In [[philosophy]], '''supervenience''' is an [[ontological]] relation that is used to describe cases where (roughly speaking)  the lower-level properties of a system determine its higher level properties. Some philosophers hold that the world is structured in to a kind of hierarchy of properties, where the higher level properties supervene on the lower level properties.  According to this type of view, social properties supervene on psychological properties, psychological properties supervene on biological properties, biological properties supervene on chemical properties, etc.  That is, the chemical properties of the world determine a distribution of biological properties, those biological properties determine a distribution of psychological properties, and so forth. So, for example, ''mind-body supervenience'' holds that "every mental phenomenon must be grounded in, or anchored to, some underlying physical base (presumably a neural state). This means that mental states can occur only in systems that can have physical properties; namely physical systems."<ref name=Kim>

It is useful to know both when supervenience does and does not obtain.  For example, the value of a piece of paper money does not supervene on the micro-features of the paper it's made out of, because the value of the money is not just determined by internal features of the paper, but also by a broader distribution of social facts and institutionsThe paper alone does not determine the value of the money, so supervenience does not obtain between the value and the paper (though it does obtain between the value of the money and some larger part of the world which includes the relevant social institutions).  Some philosophical problems can be stated in terms of questions about supervenience.  For example: do mental properties supervene on neural properties? ([[Externalists]] in the philosophy of mind say "no", internalists say "yes.")  Do the [[aesthetic]] properties of an art object supervene on physical properties of that object?
 
Though it is intuitively clear what supervenience is, formally specifying what it means involves a complex technical apparatus and a family of related but subtly different definitions.  Most definitions involve comparisons of objects for indiscernibility. According to one standard definition, a set of properties A (e.g. mental properties) supervenes on a set of properties B (e.g. neural properties), if and only if any two objects x and y which share all properties in B (are "B-[[indiscernible]]") must also share all properties in A (are "A-indiscernible"). The intuitive idea is that if you could make a physical copy of a person, you'd also be making a psychological copy of that person.  The reverse does not hold: two people could be in the same mental state, but that mental state could be supported by different brain states (the same mental state could be "[[multiple realizability|multiply realizable]]" by different brain states)The properties in B are called the ''base properties'' (or sometimes ''subjacent'' or ''subvenient properties''), and the properties in A are called the ''supervenient properties''.
 
Supervenience has traditionally been used to describe relationships between sets of properties in a manner which does not imply a strong [[Reductionism|reductive]] relationship.<ref name = "Horgan">Horgan, Terry (1993) "From supervenience to superdupervenience: meeting the demands of a material world."  ''Mind.''  102: 555-86.</ref>  For example, many hold that economic properties supervene on physical properties, in that if two [[possible world|worlds]] were exactly the same physically, they would also be the same economically. However, this does not [[Logical consequence|entail]] that economics can be reduced in any straightforward way to physics. Thus, supervenience allows one to hold that "high-level phenomena" (like those of economics, psychology, or aesthetics) depend, ultimately, on physical substance, without assuming that one can study those high-level phenomena using means appropriate to physics.

Supervenience, which means literally "coming or occurring as something novel, additional, or unexpected",<ref name="Horgan"/> from "super," meaning on, above or, additional, and "venire," meaning to come, shows occurrences in the [[Oxford English Dictionary]] dating back to 1644.
 
Its systematic use in philosophy is considered to have begun in early 20th-century [[meta-ethics]] and [[emergentism]].  As [[G.E. Moore]] wrote in 1922, "If a given thing possesses any kind of intrinsic value in a certain degree, then... anything ''exactly like it'', must, under all circumstances, possess it in exactly the same degree".<ref name="Horgan"/>  The usage also carried over into the work [[R. M. Hare]].    For discussion of the emergentist roots of supervenience see [http://plato.stanford.edu/entries/supervenience/#2.2 Stanford Encyclopedia of Philosophy: Supervenience].
 
In the 1970s [[Donald Davidson (philosopher)|Donald Davidson]] was the first to use the term to describe a broadly physicalist (and non-reductive) approach to the philosophy of mind.  As he said in 1970, "supervenience might be taken to mean that there cannot be two events alike in all physical respects but differing in some mental respects, or that an object cannot alter in some mental respects without altering in some physical respects." <ref name = "Davidson">Davidson, Donald (1970) "Mental Events." Reprinted in ''Essays on Actions and Events''. Oxford: Clarendon Press</ref>
 
In subsequent years [[Terry Horgan]], [[David Kellogg Lewis|David Lewis]], and especially [[Jaegwon Kim]] formalized the concept and began applying it to many issues in the philosophy of mind. This raised numerous questions about how various formulations relate to one another, how adequate the formulation is to various philosophical tasks (in particular, the task of formulating [[physicalism]]), and whether it avoids or entails [[reductionism]].
 
== Definitions ==
 
In the contemporary literature, there are two primary (and non-equivalent) formulations of supervenience (for both definitions let A and B be sets of properties).
 
(1) A-properties supervene on B-properties if and only if all things that are B-indiscernible are A-indiscernible.  Formally:
*<math>\forall x \forall y (\forall X_{\in B} (Xx \leftrightarrow Xy) \rightarrow \forall Y_{\in A} (Yx \leftrightarrow Yy))</math>
(2) A-properties supervene on B-properties if and only if anything that has an A-property has some B-property such that anything that has that B-property also has that A-property. Formally:
*<math>\forall x \forall X_{\in A} (Xx \rightarrow \exists Y_{\in B} (Yx \and \forall y (Yy \rightarrow Xy)))</math>
 
For example, if one lets A be a set of mental properties, B be a set of physical properties, and chooses a [[domain of discourse]] consisting of persons, then (1) says that any two persons who are physically indiscernible are mentally indiscernible, and (2) says that any person who has a mental property has some physical property such that any person with that physical property has that mental property.
 
Some points of clarification: first, the definitions above involve quantification over properties and hence [[higher order logic]]. Second, in (1), expressions of the form <math>(\forall X (Xx \leftrightarrow Xy))</math> capture the concept of sharing all properties, or being [[indiscernible]] with respect to a set of properties.  Thus, (1) can be understood more intuitively as the claim that all objects that are indiscernible with respect to a base set of properties are indiscernible with respect to a supervenient set of properties, or, as it is also sometimes said, that B-twins are A-twins. Finally, supervenience claims typically involve some modal force, however, the way that  [[Modal logic|modal]] force is specified depends on which more specific variety of supervenience one decides upon (see below).
 
(1) and (2) are sometimes called "schemata", because they do not correspond to actual supervenience relations until the sets of properties A and B, the [[domain of discourse|domain]] of entities to which those properties apply, and a modal force have been specified. For modal forms of supervenience, the modal strength of the relation is usually taken to be a parameter (that is, the possible worlds appealed to may be physically possible, logically possible, etc.). Also, note that in the early literature properties were not always central, and there remain some who prefer to frame the relation in terms of [[Predicate (logic)|predicates]], [[fact]]s, or [[entities]] instead, for example.
 
== Varieties of supervenience ==
Beginning in the 1980s, inspired largely by [[Jaegwon Kim]]'s work, philosophers proposed many varieties of supervenience, which [[David Kellogg Lewis|David Lewis]] called the "unlovely proliferation".<ref name = "Lewis">Lewis, David (1986) ''On the Plurality of Worlds.'' Oxford: Oxford University Press.</ref> These varieties are based both on (1) and (2) above, but because (1) is more common we shall focus on varieties of supervenience based on it.
 
We can begin by distinguishing between local and global supervenience:
 
* Local: For any two objects x and y, if x and y are base-indiscernible, they are supervenient-indiscernible.
 
For example, if mental states locally supervene on brain states, then being in the same brain state entails being in the same mental state.
 
* Global: For any two worlds w1 and w2, if w1 and w2 are base-indiscernible, they are supervenient-indiscernible.
 
For example, if psychological properties globally supervene on physical properties, then any two worlds physically the same will be psychologically the same.  The value of global supervenience is that it allows for supervenient properties to be determined not by local properties of an individual thing alone, but by some wider spatiotemporal distribution of things and properties. For example, something's being a dollar bill depends not only on the paper and the inks it is made out of, but also on a widely dispersed variety of features of the world it occupies.
 
Both local and global supervenience come in many forms. Local supervenience comes in strong and weak varieties:
 
* Weak: For any world w, and for any two objects x in w and y in w, if x and y are base-indiscernible, they are supervenient-indiscernible.
 
* Strong: For any worlds w1 and w2, and for any two objects x in w1 and y in w2, if x and y are base-indiscernible, they are supervenient-indiscernible.
 
The difference is essentially whether correlations between base and supervenient properties hold within actual worlds only, or across possible worlds. For example, if psychological properties strongly locally supervene on physical properties, then any two people physically the same, in any two worlds, will also be psychologically the same. On the other hand, if psychological properties only weakly locally supervene on physical properties, then those correlations between base and supervenient properties that hold in virtue of the supervenience relation are maintained within each world, but can be different in different worlds. For example, my physical duplicates in the actual world will have the same thoughts as I have; but my physical duplicates in other possible worlds may have different thoughts than I have in the actual world.
 
There are also several kinds of global supervenience relations, which were introduced to handle cases in which worlds are the same at the base level and also at the supervenient level, but where the ways the properties are connected and distributed in the worlds differ. For example, it is consistent with global mental–physical supervenience on the simple formulation described above for two worlds to have the same number of people in the same physical states, but for the mental states to be distributed over those people in different ways (e.g. I have my father's thoughts in the other world, and he has my thoughts).  To handle this, property-preserving isomorphisms (1-1 and onto functions between the objects of two worlds, whereby an object in one world has a property if and only if the object which that function takes you to in the other world does) are used, and once this is done, several varieties of global supervenience can be defined.
 
Other varieties of supervenience include multiple-domains supervenience and similarity-based supervenience.
 
==Examples of supervenient properties==
 
===Value properties===
The [[Value theory|value]] of a physical object to an [[wiktionary:agent|agent]] is sometimes held to be supervenient upon the physical properties of the object.  In [[aesthetics]], the [[beauty]] of [[A Sunday Afternoon on the Island of La Grande Jatte|La Grande Jatte]] might supervene on the physical composition of the painting (the specific [[molecules]] that make up the painting), the artistic composition of the painting (in this case, [[Pointillism|dots]]), the figures and forms of the painted image, or the painted canvas as a whole.  In [[ethics]], the [[good and evil|goodness]] of an act of [[charity (virtue)|charity]] might supervene on the physical properties of the agent, the mental state of the agent (his or her intention), or the external [[state of affairs]] itself.  Similarly, the overall suffering caused by an earthquake might supervene on the spatio-temporal entities that constituted it, the deaths it caused, or the natural disaster itself. The claim that moral properties can supervene upon non-moral properties is, however, disputed  by proponents of a more restricted use of the concept.
 
===Mental properties===
In [[philosophy of mind]], many philosophers make the general claim that the mental supervenes on the physical. In its most recent form this position derives from the work of [[Donald Davidson (philosopher)|Donald Davidson]], although in more rudimentary forms it had been advanced earlier by others. The claim can be taken in several senses, perhaps most simply in the sense that the mental ''properties'' of a person are supervenient on their physical ''properties''. Then:
 
* If two persons are indistinguishable in all of their physical properties, they must also be indistinguishable in all of their mental properties.
 
An alternative claim, advanced especially by [[John Haugeland]], is a kind of ''weak local'' supervenience claim; or, weaker still, mere ''global'' supervenience. The claim that mental properties supervene globally on physical properties requires only a quite modest commitment: any difference between two possible worlds with respect to their instantiated mental properties entails at least ''some'' difference in the physical properties instantiated in those two worlds.  Importantly, it does ''not'' require that the mental properties of an individual person supervene ''only'' on that person's physical state.
 
This weak global thesis is particularly important in the light of [[direct reference]] theories, and [[semantic externalism]] with regard to the content both of words and (more relevant to our concerns here) of ''thoughts''.  Imagine two persons who are indistinguishable in their local physical properties. One has a dog in front of his eyes and the other has a dog-image artificially projected onto his retinae. It might be reasonable to say that the former is in the ''mental state'' of seeing a dog (and of knowing that he does so), whereas the latter is not in such a state of seeing a dog (but falsely believes that he sees one).
 
There is also discussion among philosophers about mental supervenience and our experience of duration. If all mental properties supervene only upon some physical properties at durationless moments, then it may be difficult to explain our experience of duration. The philosophical belief that mental and physical events exist as a series of durationless moments that lie between the physical past and the physical future is known as [[Presentism (philosophy of time)|presentism]], and is a form of belief in [[Galilean relativity]].
 
===Computational properties===
There are several examples of supervenience to be found in [[computer network]]ing. For example, in a dial-up internet connection, the audio signal on a phone line transports [[Internet Protocol|IP packets]] between the user's computer and the [[Internet service provider]]'s computer. In this case, the arrangement of bytes in that packet supervenes on the physical properties of the phone signal. More generally, each layer of the [[OSI Model]] of computer networking supervenes on the layers below it.
 
We can find supervenience wherever a message is conveyed by a representational medium. When we see a letter "a" in a page of print, for example, the meaning ''Latin lowercase "a"'' supervenes on the geometry of the boundary of the printed [[glyph]], which in turn supervenes on the ink deposition on the paper.
 
===Biological properties===
In biological systems [[phenotype]] can be said to supervene on [[genotype]].<ref>{{cite journal | last=Mitchell, Valone| first=W.A., T.J. | year=1990 | title=The Optimization Research Program: Studying Adaptations by Their Function | journal=The Quarterly Review of Biology | volume=65 | pages=43–52| doi=10.1086/416584 | issue=1 }}</ref> This is because any genotype encodes a finite set of unique phenotypes, but any given phenotype is not produced by a finite set of genotypes. Innumerable examples of [[convergent evolution]] can be used to support this claim. Throughout nature, convergent evolution produces incredibly similar phenotypes from a diverse set of taxa with fundamentally different genotypes underpinning the phenotypes. One example is [[Foster's rule|evolution on islands]] which is a remarkably predictable example of convergent evolution where the same phenotypes consistently evolve for the same reasons.<ref>{{cite journal | last=Foster | first=J.B. | year=1964 | title=The evolution of mammals on islands | journal=Nature | volume=202 | pages=234–235| doi=10.1038/202234a0 | bibcode=1964Natur.202..234F | issue=4929 }}</ref> Organisms released from predation tend to become larger, while organisms limited by food tend to become smaller. Yet there are almost infinite numbers of genetic changes that might lead to changes in body size.<ref>{{cite journal | last=Fisher | first=R.A. | year=1918 | title=The correlation between relatives on the supposition of Mendelian inheritance | journal=Soc Edinb. | volume=52 | pages=399–433}}</ref><ref>{{cite journal | last=Kemper | first=K.E. | last=Visscher | first=P.M. | last=Gooddard | first=M.E. | year=2012 | title=Genetic architecture of body size in mammals | journal=Genome Biol. | volume=13 | pages=244| doi=10.1186/gb-2012-13-4-244 | issue=4 }}</ref> Another example of convergent evolution is the loss of sight that almost universally occurs in [[cave fish]] living in lightless pools.<ref>{{cite journal | last=Gatenby R.A., Gillies R.J and Brown J.S. | year=2011 | title= Of cancer and cave fish  | journal= Nature Reviews Cancer | volume=11 | pages=237| doi=10.1038/nrc3036 | issue=4 }}</ref> Eyes are expensive, and in lightless cave pools there is little reason for fish to have eyes. Yet, despite the remarkably consistent convergent evolution producing sightless cave fish, the genetics that produce the loss of type phenotype is different nearly every time. This is because phenotype supervenes on genotype.
 
==Arguments against supervenience-based formulations of physicalism==
Although supervenience seems to be perfectly suited to explain the predictions of physicalism (i.e. the mental is dependent on the physical), there are four main problems with it. They are ''Ephiphenomenal ectoplasm'', the ''lone ammonium molecule problem'', ''modal status problem'' and the ''problem of necessary beings.''
 
=== Epiphenomenal ectoplasm ===
 
''Epiphenomenal ectoplasm'' was proposed by Horgan and Lewis in 1983, in which they stated, a possible world (a world that could possibly exist) ''W'' is identical to our world in the distribution of all mental and physical characteristics (i.e. they are identical), except world ''W'' contains an experience called ''epiphenomenal ectoplasm'' that does not causally interact with that world. If supervenience physicalism is true, then such a world could not exist because a physical duplicate of the actual world (the world that is known to exist) could not possess an ''epiphenomenal ectoplasm''. This was rectified by [[Frank Cameron Jackson|Frank Jackson]], by adjusting the application of supervenience within physicalism to state "Physicalism is true at a possible world ''W'' if and only if any world which is a minimal physical duplicate (i.e. identical) of ''W'' is a duplicate of ''W simpliciter.''"{{Citation needed|date=August 2008}}
 
=== The lone ammonium molecule problem ===
 
The ''lone ammonium molecule problem'' provides a problem for Jackson's solution to ''epiphenomenal ectoplasm''. It was proposed by [[Jaegwon Kim]] in 1993 when he stated that according to Jackson's idea of supervenience, a possible world ''W'' was identical to the actual world, except it possessed an extra ammonium molecule on one of Saturn's rings. This may not seem to provide much of a problem, but because Jackson's solution refers only to minimal physical duplicates, this allows for the mental properties of ''W'' to be vastly different than in the actual world. If such a difference would cause mental differences on Earth, it would not be consistent with our understanding of physicalism.
 
=== Modal status problem ===
 
The ''modal status problem'' is only problematic if one thinks of physicalism as a [[Contingency|contingent]] truth (i.e. not [[logical truth|necessary truth]]), because it is described in terms of modal notions (i.e. through modal realism). The problem is presented when from the statement "Minimal physical truths entail all truths", one derives the statement "''S'' (a statement that describes all minimal physical truths) entails ''S''* (a statement that describes the world)". This statement is a necessary truth, and therefore supervenience physicalism could not be contingent. The solution to this is to accept the above statement not as the equivalent of physicalism, but as an entailment of it.
 
=== Problem of necessary beings ===
 
The ''problem of necessary beings'' was proposed by Jackson in 1998, in which he stated that a necessary being exists in all possible worlds as a [[non-physical entity]], and therefore proves physicalism false. However, physicalism allows for the existence of necessary beings, because any minimal physical duplicate would have the same mental properties as the actual world. This however is [[paradox]]ical, based on the fact that physicalism both permits and prevents the existence of such beings. This violates [[Hume's fork]] which states, "there are no necessary connections between distinct existences".

The upper levels on this chart can be considered to supervene on the lower levels.

In philosophy, supervenience is an ontological relation that is used to describe cases where (roughly speaking) the lower-level properties of a system determine its higher level properties. Some philosophers hold that the world is structured in to a kind of hierarchy of properties, where the higher level properties supervene on the lower level properties. According to this type of view, social properties supervene on psychological properties, psychological properties supervene on biological properties, biological properties supervene on chemical properties, etc. That is, the chemical properties of the world determine a distribution of biological properties, those biological properties determine a distribution of psychological properties, and so forth. So, for example, mind-body supervenience holds that "every mental phenomenon must be grounded in, or anchored to, some underlying physical base (presumably a neural state). This means that mental states can occur only in systems that can have physical properties; namely physical systems."[1]

It is useful to know both when supervenience does and does not obtain. For example, the value of a piece of paper money does not supervene on the micro-features of the paper it's made out of, because the value of the money is not just determined by internal features of the paper, but also by a broader distribution of social facts and institutions. The paper alone does not determine the value of the money, so supervenience does not obtain between the value and the paper (though it does obtain between the value of the money and some larger part of the world which includes the relevant social institutions). Some philosophical problems can be stated in terms of questions about supervenience. For example: do mental properties supervene on neural properties? (Externalists in the philosophy of mind say "no", internalists say "yes.") Do the aesthetic properties of an art object supervene on physical properties of that object?

Though it is intuitively clear what supervenience is, formally specifying what it means involves a complex technical apparatus and a family of related but subtly different definitions. Most definitions involve comparisons of objects for indiscernibility. According to one standard definition, a set of properties A (e.g. mental properties) supervenes on a set of properties B (e.g. neural properties), if and only if any two objects x and y which share all properties in B (are "B-indiscernible") must also share all properties in A (are "A-indiscernible"). The intuitive idea is that if you could make a physical copy of a person, you'd also be making a psychological copy of that person. The reverse does not hold: two people could be in the same mental state, but that mental state could be supported by different brain states (the same mental state could be "multiply realizable" by different brain states). The properties in B are called the base properties (or sometimes subjacent or subvenient properties), and the properties in A are called the supervenient properties.

Supervenience has traditionally been used to describe relationships between sets of properties in a manner which does not imply a strong reductive relationship.[2] For example, many hold that economic properties supervene on physical properties, in that if two worlds were exactly the same physically, they would also be the same economically. However, this does not entail that economics can be reduced in any straightforward way to physics. Thus, supervenience allows one to hold that "high-level phenomena" (like those of economics, psychology, or aesthetics) depend, ultimately, on physical substance, without assuming that one can study those high-level phenomena using means appropriate to physics.

History

Supervenience, which means literally "coming or occurring as something novel, additional, or unexpected",[2] from "super," meaning on, above or, additional, and "venire," meaning to come, shows occurrences in the Oxford English Dictionary dating back to 1644.

Its systematic use in philosophy is considered to have begun in early 20th-century meta-ethics and emergentism. As G.E. Moore wrote in 1922, "If a given thing possesses any kind of intrinsic value in a certain degree, then... anything exactly like it, must, under all circumstances, possess it in exactly the same degree".[2] The usage also carried over into the work R. M. Hare. For discussion of the emergentist roots of supervenience see Stanford Encyclopedia of Philosophy: Supervenience.

In the 1970s Donald Davidson was the first to use the term to describe a broadly physicalist (and non-reductive) approach to the philosophy of mind. As he said in 1970, "supervenience might be taken to mean that there cannot be two events alike in all physical respects but differing in some mental respects, or that an object cannot alter in some mental respects without altering in some physical respects." [3]

In subsequent years Terry Horgan, David Lewis, and especially Jaegwon Kim formalized the concept and began applying it to many issues in the philosophy of mind. This raised numerous questions about how various formulations relate to one another, how adequate the formulation is to various philosophical tasks (in particular, the task of formulating physicalism), and whether it avoids or entails reductionism.

Definitions

In the contemporary literature, there are two primary (and non-equivalent) formulations of supervenience (for both definitions let A and B be sets of properties).

(1) A-properties supervene on B-properties if and only if all things that are B-indiscernible are A-indiscernible. Formally:

(2) A-properties supervene on B-properties if and only if anything that has an A-property has some B-property such that anything that has that B-property also has that A-property. Formally:

For example, if one lets A be a set of mental properties, B be a set of physical properties, and chooses a domain of discourse consisting of persons, then (1) says that any two persons who are physically indiscernible are mentally indiscernible, and (2) says that any person who has a mental property has some physical property such that any person with that physical property has that mental property.

Some points of clarification: first, the definitions above involve quantification over properties and hence higher order logic. Second, in (1), expressions of the form capture the concept of sharing all properties, or being indiscernible with respect to a set of properties. Thus, (1) can be understood more intuitively as the claim that all objects that are indiscernible with respect to a base set of properties are indiscernible with respect to a supervenient set of properties, or, as it is also sometimes said, that B-twins are A-twins. Finally, supervenience claims typically involve some modal force, however, the way that modal force is specified depends on which more specific variety of supervenience one decides upon (see below).

(1) and (2) are sometimes called "schemata", because they do not correspond to actual supervenience relations until the sets of properties A and B, the domain of entities to which those properties apply, and a modal force have been specified. For modal forms of supervenience, the modal strength of the relation is usually taken to be a parameter (that is, the possible worlds appealed to may be physically possible, logically possible, etc.). Also, note that in the early literature properties were not always central, and there remain some who prefer to frame the relation in terms of predicates, facts, or entities instead, for example.

Varieties of supervenience

Beginning in the 1980s, inspired largely by Jaegwon Kim's work, philosophers proposed many varieties of supervenience, which David Lewis called the "unlovely proliferation".[4] These varieties are based both on (1) and (2) above, but because (1) is more common we shall focus on varieties of supervenience based on it.

We can begin by distinguishing between local and global supervenience:

  • Local: For any two objects x and y, if x and y are base-indiscernible, they are supervenient-indiscernible.

For example, if mental states locally supervene on brain states, then being in the same brain state entails being in the same mental state.

  • Global: For any two worlds w1 and w2, if w1 and w2 are base-indiscernible, they are supervenient-indiscernible.

For example, if psychological properties globally supervene on physical properties, then any two worlds physically the same will be psychologically the same. The value of global supervenience is that it allows for supervenient properties to be determined not by local properties of an individual thing alone, but by some wider spatiotemporal distribution of things and properties. For example, something's being a dollar bill depends not only on the paper and the inks it is made out of, but also on a widely dispersed variety of features of the world it occupies.

Both local and global supervenience come in many forms. Local supervenience comes in strong and weak varieties:

  • Weak: For any world w, and for any two objects x in w and y in w, if x and y are base-indiscernible, they are supervenient-indiscernible.
  • Strong: For any worlds w1 and w2, and for any two objects x in w1 and y in w2, if x and y are base-indiscernible, they are supervenient-indiscernible.

The difference is essentially whether correlations between base and supervenient properties hold within actual worlds only, or across possible worlds. For example, if psychological properties strongly locally supervene on physical properties, then any two people physically the same, in any two worlds, will also be psychologically the same. On the other hand, if psychological properties only weakly locally supervene on physical properties, then those correlations between base and supervenient properties that hold in virtue of the supervenience relation are maintained within each world, but can be different in different worlds. For example, my physical duplicates in the actual world will have the same thoughts as I have; but my physical duplicates in other possible worlds may have different thoughts than I have in the actual world.

There are also several kinds of global supervenience relations, which were introduced to handle cases in which worlds are the same at the base level and also at the supervenient level, but where the ways the properties are connected and distributed in the worlds differ. For example, it is consistent with global mental–physical supervenience on the simple formulation described above for two worlds to have the same number of people in the same physical states, but for the mental states to be distributed over those people in different ways (e.g. I have my father's thoughts in the other world, and he has my thoughts). To handle this, property-preserving isomorphisms (1-1 and onto functions between the objects of two worlds, whereby an object in one world has a property if and only if the object which that function takes you to in the other world does) are used, and once this is done, several varieties of global supervenience can be defined.

Other varieties of supervenience include multiple-domains supervenience and similarity-based supervenience.

Examples of supervenient properties

Value properties

The value of a physical object to an agent is sometimes held to be supervenient upon the physical properties of the object. In aesthetics, the beauty of La Grande Jatte might supervene on the physical composition of the painting (the specific molecules that make up the painting), the artistic composition of the painting (in this case, dots), the figures and forms of the painted image, or the painted canvas as a whole. In ethics, the goodness of an act of charity might supervene on the physical properties of the agent, the mental state of the agent (his or her intention), or the external state of affairs itself. Similarly, the overall suffering caused by an earthquake might supervene on the spatio-temporal entities that constituted it, the deaths it caused, or the natural disaster itself. The claim that moral properties can supervene upon non-moral properties is, however, disputed by proponents of a more restricted use of the concept.

Mental properties

In philosophy of mind, many philosophers make the general claim that the mental supervenes on the physical. In its most recent form this position derives from the work of Donald Davidson, although in more rudimentary forms it had been advanced earlier by others. The claim can be taken in several senses, perhaps most simply in the sense that the mental properties of a person are supervenient on their physical properties. Then:

  • If two persons are indistinguishable in all of their physical properties, they must also be indistinguishable in all of their mental properties.

An alternative claim, advanced especially by John Haugeland, is a kind of weak local supervenience claim; or, weaker still, mere global supervenience. The claim that mental properties supervene globally on physical properties requires only a quite modest commitment: any difference between two possible worlds with respect to their instantiated mental properties entails at least some difference in the physical properties instantiated in those two worlds. Importantly, it does not require that the mental properties of an individual person supervene only on that person's physical state.

This weak global thesis is particularly important in the light of direct reference theories, and semantic externalism with regard to the content both of words and (more relevant to our concerns here) of thoughts. Imagine two persons who are indistinguishable in their local physical properties. One has a dog in front of his eyes and the other has a dog-image artificially projected onto his retinae. It might be reasonable to say that the former is in the mental state of seeing a dog (and of knowing that he does so), whereas the latter is not in such a state of seeing a dog (but falsely believes that he sees one).

There is also discussion among philosophers about mental supervenience and our experience of duration. If all mental properties supervene only upon some physical properties at durationless moments, then it may be difficult to explain our experience of duration. The philosophical belief that mental and physical events exist as a series of durationless moments that lie between the physical past and the physical future is known as presentism, and is a form of belief in Galilean relativity.

Computational properties

There are several examples of supervenience to be found in computer networking. For example, in a dial-up internet connection, the audio signal on a phone line transports IP packets between the user's computer and the Internet service provider's computer. In this case, the arrangement of bytes in that packet supervenes on the physical properties of the phone signal. More generally, each layer of the OSI Model of computer networking supervenes on the layers below it.

We can find supervenience wherever a message is conveyed by a representational medium. When we see a letter "a" in a page of print, for example, the meaning Latin lowercase "a" supervenes on the geometry of the boundary of the printed glyph, which in turn supervenes on the ink deposition on the paper.

Biological properties

In biological systems phenotype can be said to supervene on genotype.[5] This is because any genotype encodes a finite set of unique phenotypes, but any given phenotype is not produced by a finite set of genotypes. Innumerable examples of convergent evolution can be used to support this claim. Throughout nature, convergent evolution produces incredibly similar phenotypes from a diverse set of taxa with fundamentally different genotypes underpinning the phenotypes. One example is evolution on islands which is a remarkably predictable example of convergent evolution where the same phenotypes consistently evolve for the same reasons.[6] Organisms released from predation tend to become larger, while organisms limited by food tend to become smaller. Yet there are almost infinite numbers of genetic changes that might lead to changes in body size.[7][8] Another example of convergent evolution is the loss of sight that almost universally occurs in cave fish living in lightless pools.[9] Eyes are expensive, and in lightless cave pools there is little reason for fish to have eyes. Yet, despite the remarkably consistent convergent evolution producing sightless cave fish, the genetics that produce the loss of type phenotype is different nearly every time. This is because phenotype supervenes on genotype.

Arguments against supervenience-based formulations of physicalism

Although supervenience seems to be perfectly suited to explain the predictions of physicalism (i.e. the mental is dependent on the physical), there are four main problems with it. They are Ephiphenomenal ectoplasm, the lone ammonium molecule problem, modal status problem and the problem of necessary beings.

Epiphenomenal ectoplasm

Epiphenomenal ectoplasm was proposed by Horgan and Lewis in 1983, in which they stated, a possible world (a world that could possibly exist) W is identical to our world in the distribution of all mental and physical characteristics (i.e. they are identical), except world W contains an experience called epiphenomenal ectoplasm that does not causally interact with that world. If supervenience physicalism is true, then such a world could not exist because a physical duplicate of the actual world (the world that is known to exist) could not possess an epiphenomenal ectoplasm. This was rectified by Frank Jackson, by adjusting the application of supervenience within physicalism to state "Physicalism is true at a possible world W if and only if any world which is a minimal physical duplicate (i.e. identical) of W is a duplicate of W simpliciter."Potter or Ceramic Artist Truman Bedell from Rexton, has interests which include ceramics, best property developers in singapore developers in singapore and scrabble. Was especially enthused after visiting Alejandro de Humboldt National Park.

The lone ammonium molecule problem

The lone ammonium molecule problem provides a problem for Jackson's solution to epiphenomenal ectoplasm. It was proposed by Jaegwon Kim in 1993 when he stated that according to Jackson's idea of supervenience, a possible world W was identical to the actual world, except it possessed an extra ammonium molecule on one of Saturn's rings. This may not seem to provide much of a problem, but because Jackson's solution refers only to minimal physical duplicates, this allows for the mental properties of W to be vastly different than in the actual world. If such a difference would cause mental differences on Earth, it would not be consistent with our understanding of physicalism.

Modal status problem

The modal status problem is only problematic if one thinks of physicalism as a contingent truth (i.e. not necessary truth), because it is described in terms of modal notions (i.e. through modal realism). The problem is presented when from the statement "Minimal physical truths entail all truths", one derives the statement "S (a statement that describes all minimal physical truths) entails S* (a statement that describes the world)". This statement is a necessary truth, and therefore supervenience physicalism could not be contingent. The solution to this is to accept the above statement not as the equivalent of physicalism, but as an entailment of it.

Problem of necessary beings

The problem of necessary beings was proposed by Jackson in 1998, in which he stated that a necessary being exists in all possible worlds as a non-physical entity, and therefore proves physicalism false. However, physicalism allows for the existence of necessary beings, because any minimal physical duplicate would have the same mental properties as the actual world. This however is paradoxical, based on the fact that physicalism both permits and prevents the existence of such beings. This violates Hume's fork which states, "there are no necessary connections between distinct existences".
