Do not fill this in! ===Incompatibilism=== {{Main|Incompatibilism}} Incompatibilism is the position that free will and determinism are logically incompatible, and that the major question regarding whether or not people have free will is thus whether or not their actions are determined. "Hard determinists", such as [[Baron d'Holbach|d'Holbach]], are those incompatibilists who accept determinism and reject free will. In contrast, "[[Libertarianism (metaphysics)|metaphysical libertarians]]", such as [[Thomas Reid]], [[Peter van Inwagen]], and [[Robert Kane (philosopher)|Robert Kane]], are those incompatibilists who accept free will and deny determinism, holding the view that some form of indeterminism is true.<ref name="Wagen">{{Cite book |last=van Invagen |first=P. |title=An Essay on Free Will |publisher=[[Clarendon Press]]|isbn=0-19-824924-1 |year=1983 |location=Oxford}}</ref> Another view is that of hard incompatibilists, which state that free will is incompatible with both [[determinism]] and [[indeterminism]].<ref name="Derk1">{{cite book |author=Pereboom, D. |year=2003 |title=Living without Free Will |publisher=Cambridge University Press |url=https://books.google.com/books?id=9sKZ1rAO2BwC |isbn=978-0-521-79198-4}}</ref> Traditional arguments for incompatibilism are based on an "[[intuition pump]]": if a person is like other mechanical things that are determined in their behavior such as a wind-up toy, a billiard ball, a puppet, or a robot, then people must not have free will.<ref name="Wagen" /><ref>{{cite journal | last1 = Fischer | first1 = J.M. | year = 1983 | title = Incompatibilism | journal = Philosophical Studies | volume = 43 | pages = 121–37 | doi = 10.1007/BF01112527 }}</ref> This argument has been rejected by compatibilists such as [[Daniel Dennett]] on the grounds that, even if humans have something in common with these things, it remains possible and plausible that we are different from such objects in important ways.<ref name="DD1"/> Another argument for incompatibilism is that of the "causal chain". Incompatibilism is key to the idealist theory of free will. Most incompatibilists reject the idea that freedom of action consists simply in "voluntary" behavior. They insist, rather, that free will means that someone must be the "ultimate" or "originating" cause of his actions. They must be ''[[causa sui]]'', in the traditional phrase. Being responsible for one's choices is the first cause of those choices, where first cause means that there is no antecedent cause of that cause. The argument, then, is that if a person has free will, then they are the ultimate cause of their actions. If determinism is true, then all of a person's choices are caused by events and facts outside their control. So, if everything someone does is caused by events and facts outside their control, then they cannot be the ultimate cause of their actions. Therefore, they cannot have free will.<ref>{{Cite book |last=Kane |first=R. |title=The Significance of Free Will |publisher=Oxford University Press |year=1996 |isbn=0-19-512656-4 |location=Oxford}}</ref><ref>{{Cite book |last=Campbell |first=C.A. |title=On Selfhood and Godhood |publisher=George Allen and Unwin |year=1957 |isbn=0-415-29624-2 |location=London}}</ref><ref>{{Cite book |last=Sartre |first=J.P. |title=Being and Nothingness |publisher=Washington Square Press |year=1943 |edition=reprint 1993 |location=New York}} Sartre also provides a psychological version of the argument by claiming that if man's actions are not his own, he would be in ''bad faith''.</ref> This argument has also been challenged by various compatibilist philosophers.<ref>{{Cite book |last=Fischer |first=R.M. |title=The Metaphysics of Free Will |publisher=Blackwell |year=1994 |location=Oxford}}</ref><ref>{{Cite book |last=Bok |first=H. |title=Freedom and Responsibility |publisher=Princeton University Press |year=1998 |isbn=0-691-01566-X |location=Princeton}}</ref> A third argument for incompatibilism was formulated by [[Carl Ginet]] in the 1960s and has received much attention in the modern literature. The simplified argument runs along these lines: if determinism is true, then we have no control over the events of the past that determined our present state and no control over the laws of nature. Since we can have no control over these matters, we also can have no control over the ''consequences'' of them. Since our present choices and acts, under determinism, are the necessary consequences of the past and the laws of nature, then we have no control over them and, hence, no free will. This is called the ''consequence argument''.<ref>{{Cite book |last=Ginet |first=Carl |title=Freedom and Determinisim |publisher=Random House |year=1966 |editor-last=Lehrer |editor-first=Keith |pages=87–104 |chapter=Might We Have No Choice}}</ref><ref name="Ving">{{Cite book |last1=van Inwagen |first1=P. |title=Metaphysics: The Big Questions |last2=Zimmerman |first2=D. |publisher=Blackwell |location=Oxford |year=1998}}</ref> [[Peter van Inwagen]] remarks that C.D.

For example, if Jane is a compatibilist and she has just sat down on the sofa, then she is committed to the claim that she could have remained standing, if she had so desired. But it [[Logical consequence|follows from]] the consequence argument that, if Jane had remained standing, she would have either generated a contradiction, violated the laws of nature or changed the past. Hence, compatibilists are committed to the existence of "incredible abilities", according to Ginet and van Inwagen. One response to this argument is that it equivocates on the notions of abilities and necessities, or that the free will evoked to make any given choice is really an illusion and the choice had been made all along, oblivious to its "decider".<ref name="Ving" /> [[David Kellogg Lewis|David Lewis]] suggests that compatibilists are only committed to the ability to do something otherwise if ''different circumstances'' had actually obtained in the past.<ref>{{cite journal | doi = 10.1111/j.1755-2567.1981.tb00473.x | last1 = Lewis | first1 = D. | s2cid = 170811962 | year = 2008| title = Are We Free to Break the Laws? | journal = Theoria | volume = 47 | issue = 3| pages = 113–21 }}</ref> Using ''T'', ''F'' for "true" and "false" and ''?'' for undecided, there are exactly nine positions regarding determinism/free will that consist of any two of these three possibilities:<ref name=Strawson> {{cite book |title=Freedom and belief |url=https://archive.org/details/freedombelief00stra |url-access=limited |author= Strawson, Galen|page=[https://archive.org/details/freedombelief00stra/page/n66 6] |isbn=978-0-19-924750-9 |edition=Revised |year=2010 |publisher=Oxford University Press}} </ref> {| class="wikitable" style="text-align:center; width:50%;" |+Galen Strawson's table<ref name=Strawson/> |- | ! scope="col" | 1 ! scope="col" | 2 ! scope="col" | 3 ! scope="col" | 4 ! scope="col" | 5 ! scope="col" | 6 ! scope="col" | 7 ! scope="col" | 8 ! scope="col" | 9 |- !scope="row"| Determinism ''D'' |T |F |T |F |T |F |? |? |? |- !scope="row"| Free will ''FW'' |F |T |T |F |? |? |F |T |? |- |} ''Incompatibilism'' may occupy any of the nine positions except (5), (8) or (3), which last corresponds to ''soft determinism''.

Non-physical theories hold that the events in the brain that lead to the performance of actions do not have an entirely physical explanation, which requires that the world is not closed under physics. This includes [[interactionist dualism]], which claims that some non-physical [[mind]], will, or [[soul]] overrides physical [[causality]]. Physical determinism implies there is only one possible future and is therefore not compatible with libertarian free will. As consequent of incompatibilism, metaphysical libertarian explanations that do not involve dispensing with [[physicalism]] require physical indeterminism, such as probabilistic subatomic particle behavior – theory unknown to many of the early writers on free will. Incompatibilist theories can be categorised based on the type of indeterminism they require; uncaused events, non-deterministically caused events, and agent/substance-caused events.<ref name=stanfordincompatibilismtheories>{{cite encyclopedia|last=Randolph |first=Clarke |editor=Edward N.

They either rely upon a world that is not causally closed, or physical indeterminism. Non-causal accounts often claim that each intentional action requires a choice or volition – a willing, trying, or endeavoring on behalf of the agent (such as the cognitive component of lifting one's arm).<ref name=LumerNannini2007>{{cite book|author1=Christoph Lumer|author2=Sandro Nannini|title=Intentionality, Deliberation and Autonomy: The Action-Theoretic Basis of Practical Philosophy|url=https://books.google.com/books?id=4LzldxvSk4kC|access-date=27 December 2012|year=2007|publisher=Ashgate Publishing, Ltd.|isbn=978-0-7546-6058-3}}</ref><ref name=McCann1998>{{cite book|author=Hugh McCann|title=The Works of Agency: On Human Action, Will, and Freedom|url=https://archive.org/details/worksofagencyonh00mcca_0|url-access=registration|access-date=27 December 2012|year=1998|publisher=Cornell University Press|isbn=978-0-8014-8583-1}}</ref> Such intentional actions are interpreted as free actions. It has been suggested, however, that such acting cannot be said to exercise control over anything in particular. According to non-causal accounts, the causation by the agent cannot be analysed in terms of causation by mental states or events, including desire, belief, intention of something in particular, but rather is considered a matter of spontaneity and creativity. The exercise of intent in such intentional actions is not that which determines their freedom – intentional actions are rather self-generating. The "actish feel" of some intentional actions do not "constitute that event's activeness, or the agent's exercise of active control", rather they "might be brought about by direct stimulation of someone's brain, in the absence of any relevant desire or intention on the part of that person".<ref name=stanfordincompatibilismtheories /> Another question raised by such non-causal theory, is how an agent acts upon reason, if the said intentional actions are spontaneous. Some non-causal explanations involve invoking [[panpsychism]], the theory that a quality of [[mind]] is associated with all particles, and pervades the entire universe, in both animate and inanimate entities. ====Event-causal theories==== Event-causal accounts of incompatibilist free will typically rely upon physicalist models of mind (like those of the compatibilist), yet they presuppose physical indeterminism, in which certain indeterministic events are said to be caused by the agent. A number of event-causal accounts of free will have been created, referenced here as ''deliberative indeterminism'', ''centred accounts'', and ''efforts of will theory''.<ref name=stanfordincompatibilismtheories /> The first two accounts do not require free will to be a fundamental constituent of the universe. Ordinary randomness is appealed to as supplying the "elbow room" that libertarians believe necessary. A first common objection to event-causal accounts is that the indeterminism could be destructive and could therefore diminish control by the agent rather than provide it (related to the problem of origination). A second common objection to these models is that it is questionable whether such indeterminism could add any value to deliberation over that which is already present in a deterministic world. ''Deliberative indeterminism'' asserts that the indeterminism is confined to an earlier stage in the decision process.<ref name=Ekstrom2000>{{cite book|author=Laura Waddell Ekstrom|title=Free Will: A Philosophical Study|url=https://books.google.com/books?id=oaOpa7qlz3kC|access-date=27 December 2012|year=2000|publisher=Westview Press|isbn=978-0-8133-9093-2}}</ref><ref name=Mele2006>{{cite book|author=Alfred R.

''Efforts of will theory'' is related to the role of will power in decision making. It suggests that the indeterminacy of agent volition processes could map to the indeterminacy of certain physical events – and the outcomes of these events could therefore be considered caused by the agent. Models of [[Volition (psychology)|volition]] have been constructed in which it is seen as a particular kind of complex, high-level process with an element of physical indeterminism.

It is also required that the agent's causing of that event is not causally determined by prior events. A number of problems have been identified with this view. Firstly, it is difficult to establish the reason for any given choice by the agent, which suggests they may be random or determined by ''luck'' (without an underlying basis for the free will decision). Secondly, it has been questioned whether physical events can be caused by an external substance or mind – a common problem associated with [[dualism (philosophy of mind)|interactionalist dualism]]. ====Hard incompatibilism==== Hard incompatibilism is the idea that free will cannot exist, whether the world is deterministic or not. [[Derk Pereboom (philosopher)|Derk Pereboom]] has defended hard incompatibilism, identifying a variety of positions where free will is irrelevant to indeterminism/determinism, among them the following: :#Determinism (D) is true, D does not imply we lack free will (F), but in fact we do lack F. :#D is true, D does not imply we lack F, but in fact we don't know if we have F. :#D is true, and we do have F. :#D is true, we have F, and F implies D. :#D is unproven, but we have F. :#D isn't true, we do have F, and would have F even if D were true. :#D isn't true, we don't have F, but F is compatible with D. ::::::Derk Pereboom, ''Living without Free Will'',<ref name="Derk1"/> p. xvi. Pereboom calls positions 3 and 4 ''soft determinism'', position 1 a form of ''hard determinism'', position 6 a form of ''classical libertarianism'', and any position that includes having F as ''compatibilism''. [[John Locke]] denied that the phrase "free will" made any sense (compare with [[theological noncognitivism]], a similar stance on the [[existence of God]]). He also took the view that the truth of determinism was irrelevant. He believed that the defining feature of voluntary behavior was that individuals have the ability to ''postpone'' a decision long enough to reflect or deliberate upon the consequences of a choice: "...the will in truth, signifies nothing but a power, or ability, to prefer or choose".<ref>Locke, J. (1689). ''[[An Essay Concerning Human Understanding]]'' (1998, ed). Book II, Chap. XXI, Sec. 17. Penguin Classics, Toronto.</ref> The contemporary philosopher [[Galen Strawson]] agrees with Locke that the truth or falsity of determinism is irrelevant to the problem.<ref name="GStraw">Strawson, G. (1998, 2004). "Free will". In E. Craig (ed.), ''Routledge Encyclopedia of Philosophy''. London: Routledge. Retrieved August 17, 2006, [http://www.rep.routledge.com/article/V014 ((online))] {{webarchive|url=https://web.archive.org/web/20070825055350/http://www.rep.routledge.com/article/V014 |date=2007-08-25 }}</ref> He argues that the notion of free will leads to an infinite regress and is therefore senseless. According to Strawson, if one is responsible for what one does in a given situation, then one must be responsible for the way one is in certain mental respects. But it is impossible for one to be responsible for the way one is in any respect. This is because to be responsible in some situation ''S'', one must have been responsible for the way one was at ''S<sup>−1</sup>''. To be responsible for the way one was at ''S<sup>−1</sup>'', one must have been responsible for the way one was at ''S<sup>−2</sup>'', and so on. At some point in the chain, there must have been an act of origination of a new causal chain. But this is impossible. Man cannot create himself or his mental states ''[[ex nihilo]]''. This argument entails that free will itself is absurd, but not that it is incompatible with determinism. Strawson calls his own view "pessimism" but it can be classified as [[hard incompatibilism]].<ref name="GStraw"/> ===== Causal determinism ===== {{Main|Determinism}} Causal determinism is the concept that [[Event (philosophy)|events]] within a given [[paradigm]] are bound by [[causality]] in such a way that any state (of an object or event) is completely determined by prior states. Causal determinism proposes that there is an unbroken chain of prior occurrences stretching back to the origin of the universe. Causal determinists believe that there is nothing uncaused or [[Causa sui|self-caused]]. The most common form of causal determinism is nomological determinism (or scientific determinism), the notion that the past and the present dictate the future entirely and necessarily by rigid natural laws, that every occurrence results inevitably from prior events. [[Quantum mechanics]] poses a serious challenge to this view. Fundamental debate continues over whether the physical universe is likely to be [[causal determinism|deterministic]]. Although the scientific method cannot be used to rule out [[indeterminism]] with respect to violations of [[causal closure]], it can be used to identify indeterminism in natural law. [[Interpretations of quantum mechanics]] at present are both [[deterministic system|deterministic]] and [[indeterminism|indeterministic]], and are being constrained by ongoing experimentation.<ref name=GroblacherPaterek2007>{{cite journal|last1=Groblacher|first1=Simon|last2=Paterek|first2=Tomasz|last3=Kaltenbaek|first3=Rainer|last4=Brukner|first4=Caslav|last5=Zukowski|first5=Marek|last6=Aspelmeyer|first6=Markus|last7=Zeilinger|first7=Anton|title=An experimental test of non-local realism|journal=Nature|volume=446|issue=7138|year=2007|pages=871–75|issn=0028-0836|doi=10.1038/nature05677|pmid=17443179|arxiv=0704.2529|bibcode=2007Natur.446..871G|s2cid=4412358}}</ref> ===== Destiny and fate ===== {{Main|Destiny}} Destiny or fate is a predetermined course of events. It may be conceived as a predetermined future, whether in general or of an individual. It is a concept based on the belief that there is a fixed natural order to the cosmos. Although often used interchangeably, the words "fate" and "destiny" have distinct connotations. [[Fate]] generally implies there is a set course that cannot be deviated from, and over which one has no control. Fate is related to [[determinism]], but makes no specific claim of physical determinism. Even with physical indeterminism an event could still be fated externally (see for instance [[theological determinism]]). Destiny likewise is related to determinism, but makes no specific claim of physical determinism. Even with physical indeterminism an event could still be destined to occur. [[Destiny]] implies there is a set course that cannot be deviated from, but does not of itself make any claim with respect to the setting of that course (i.e., it does not necessarily conflict with [[incompatibilist]] free will). Free will if existent could be the mechanism by which that destined outcome is chosen (determined to represent destiny).<ref name="Blackwell2011">{{cite book|author=Ben C. Blackwell|title=Christosis: Pauline Soteriology in Light of Deification in Irenaeus and Cyril of Alexandria|url=https://books.google.com/books?id=WDZxSq9nx4IC|access-date=8 December 2012|year=2011|publisher=Mohr Siebeck|isbn=978-3-16-151672-6|page=50}}</ref> ===== Logical determinism ===== {{See also|B-theory of time}} Discussion regarding destiny does not necessitate the existence of supernatural powers. Logical [[determinism]] or determinateness is the notion that all propositions, whether about the past, present, or future, are either true or false. This creates a unique problem for free will given that propositions about the future already have a truth value in the present (that is it is already determined as either true or false), and is referred to as the [[problem of future contingents]]. ===== Omniscience ===== {{Main|Omniscience}} [[Omniscience]] is the capacity to know everything that there is to know (included in which are all future events), and is a property often attributed to a creator deity. Omniscience implies the existence of destiny. Some authors have claimed that free will cannot coexist with omniscience. One argument asserts that an omniscient creator not only implies destiny but a form of high level [[predeterminism]] such as hard [[theological determinism]] or [[predestination]] – that they have independently fixed all events and outcomes in the universe in advance. In such a case, even if an individual could have influence over their lower level physical system, their choices in regard to this cannot be their own, as is the case with libertarian free will. Omniscience features as an [[incompatible-properties argument]] for the existence of [[God]], known as the [[argument from free will]], and is closely related to other such arguments, for example the incompatibility of [[omnipotence]] with a good creator deity (i.e. if a deity knew what they were going to choose, then they are responsible for letting them choose it). =====Predeterminism===== {{Main|Predeterminism}} {{See also|Predestination}} [[Predeterminism]] is the idea that all events are determined in advance.<ref name="McKewan">{{cite encyclopedia |last=McKewan |first=Jaclyn |editor=H.

Predeterminism is frequently taken to mean that human actions cannot interfere with (or have no bearing on) the outcomes of a pre-determined course of events, and that one's destiny was established externally (for example, exclusively by a creator deity). The concept of predeterminism is often argued by invoking [[causal determinism]], implying that there is an unbroken [[chain of prior occurrences]] stretching back to the origin of the universe. In the case of predeterminism, this chain of events has been pre-established, and human actions cannot interfere with the outcomes of this pre-established chain. Predeterminism can be used to mean such pre-established causal determinism, in which case it is categorised as a specific type of [[determinism]].<ref name="McKewan" /><ref>{{cite web |url=http://philosophy.lander.edu/ethics/notes-determinism.html |title=Some Varieties of Free Will and Determinism |author=<!--Staff writer(s); no by-line.--> |date=10 September 2009 <!-- date found by checking page's source code where format of date given as m.d.y -->|work=Philosophy 302: Ethics |publisher=philosophy.lander.edu |access-date=19 December 2012| quote=Predeterminism: the philosophical and theological view that combines God with determinism.

A rejection of theological determinism (or [[omniscience|divine foreknowledge]]) is classified as theological incompatibilism also (see figure, bottom), and is relevant to a more general discussion of free will.<ref name="stanfordforeknowledge"/> The basic argument for theological fatalism in the case of weak theological determinism is as follows: # Assume divine foreknowledge or [[omniscience]] # [[infallibility|Infallible]] foreknowledge implies destiny (it is known for certain what one will do) # Destiny eliminates alternate possibility (one cannot do otherwise) # Assert incompatibility with metaphysical libertarian free will This argument is very often accepted as a basis for theological incompatibilism: denying either libertarian free will or divine foreknowledge (omniscience) and therefore theological determinism. On the other hand, theological compatibilism must attempt to find problems with it. The formal version of the argument rests on a number of premises, many of which have received some degree of contention. Theological compatibilist responses have included: * Deny the truth value of [[Problem of future contingents|future contingents]], although this denies foreknowledge and therefore theological determinism. * Assert differences in non-temporal knowledge (space-time independence), an approach taken for example by [[Boethius]],<ref>{{cite book | author=Boethius | title=The Consolation of Philosophy | chapter-url=https://archive.org/details/theconsolationof14328gut | chapter=Book V, Prose vi}}</ref> [[Thomas Aquinas]],<ref>{{cite book | author=Aquinas, St. Thomas | title=Summa Theologica | chapter-url=https://archive.org/details/in.ernet.dli.2015.126741 | chapter=Ia, q. 14, art 13.| year=1923 }} See [[Summa Theologica]]</ref> and [[C.S.

By the same principle, metaphysical libertarianism (a form of incompatibilism with respect to physical determinism) might be classified as compatibilism with respect to theological determinism (if it was assumed such free will events were pre-ordained and therefore were destined to occur, but of which whose outcomes were not "predestined" or determined by God). If hard theological determinism is accepted (if it was assumed instead that such outcomes were predestined by God), then metaphysical libertarianism is not, however, possible, and would require reclassification (as hard incompatibilism for example, given that the universe is still assumed to be indeterministic – although the classification of hard determinism is technically valid also).<ref name=VanArragon2010 /> ====Mind–body problem==== {{Main|Mind–body problem}} {{See also|Philosophy of mind|Dualism (philosophy of mind)|Monism|Physicalism}} [[File:Frans Hals - Portret van René Descartes.jpg|thumb|upright|[[René Descartes]]]] The idea of ''free will'' is one aspect of the [[mind–body problem]], that is, consideration of the relation between [[mind]] (for example, consciousness, memory, and judgment) and body (for example, the [[human brain]] and [[nervous system]]). [[Philosophy of Mind|Philosophical models of mind]] are divided into [[Physicalism|physical]] and non-physical expositions. [[Dualism (philosophy of mind)#Substance dualism|Cartesian dualism]] holds that the mind is a nonphysical substance, the seat of consciousness and intelligence, and is not identical with physical states of the brain or body. It is suggested that although the two worlds do interact, each retains some measure of autonomy. Under cartesian dualism external mind is responsible for bodily action, although unconscious brain activity is often caused by external events (for example, the instantaneous reaction to being burned).<ref name=Peruzzi>See for example: {{cite book |title=Mind and Causality |chapter=Chapter 5: Mental causation and intentionality in a mind naturalizing theory |author=Sandro Nannini |editor=Alberto Peruzzi |chapter-url=https://books.google.com/books?id=zYEPifPTQK4C&pg=PA75 |pages=69 ''ff'' |isbn=978-1-58811-475-4 |publisher=John Benjamins Publishing |year=2004}}</ref> Cartesian dualism implies that the physical world is not deterministic – and in which external mind controls (at least some) physical events, providing an interpretation of [[incompatibilism|incompatibilist]] free will. Stemming from Cartesian dualism, a formulation sometimes called ''[[Dualism (philosophy of mind)#Interactionism|interactionalist dualism]]'' suggests a two-way interaction, that some physical events cause some mental acts and some mental acts cause some physical events. One modern vision of the possible separation of mind and body is the [[Popper's three worlds|"three-world" formulation]] of [[Karl Popper|Popper]].<ref name=Popper>{{cite book |title=All Life is Problem Solving |chapter=Notes of a realist on the body-mind problem |author=Karl Raimund Popper |chapter-url=https://books.google.com/books?id=Pa3cZYwdq28C&pg=PA23 |pages=23 ''ff'' |isbn=978-0-415-17486-2 |year=1999 |publisher=Psychology Press |quote=The body-mind relationship...includes the problem of man's position in the physical world...'World 1'.

Other forms of epistemological pluralist dualism include [[psychophysical parallelism]] and [[epiphenomenalism]]. Epistemological pluralism is one view in which the mind-body problem is ''not'' reducible to the concepts of the natural sciences. A contrasting approach is called [[physicalism]]. Physicalism is a [[philosophical theory]] holding that everything that [[existence|exists]] is no more extensive than its [[physical properties]]; that is, that there are no non-physical substances (for example physically independent minds). Physicalism can be reductive or non-reductive. [[Reductive physicalism]] is grounded in the idea that everything in the world can actually be reduced analytically to its fundamental physical, or material, basis. Alternatively, [[non-reductive physicalism]] asserts that mental properties form a separate ontological class to physical properties: that mental states (such as [[qualia]]) are not ontologically reducible to physical states. Although one might suppose that mental states and neurological states are different in kind, that does not rule out the possibility that mental states are correlated with neurological states. In one such construction, [[anomalous monism]], mental events [[Supervenience|''supervene'']] on physical events, describing the [[emergence]] of mental properties correlated with physical properties – implying causal reducibility. Non-reductive physicalism is therefore often categorised as [[property dualism]] rather than [[monism]], yet other types of property dualism do not adhere to the causal reducibility of mental states (see epiphenomenalism). [[Incompatibilism]] requires a distinction between the mental and the physical, being a commentary on the incompatibility of (determined) physical reality and one's presumably distinct experience of will. Secondarily, [[metaphysical libertarianism|metaphysical libertarian]] free will must assert influence on physical reality, and where mind is responsible for such influence (as opposed to ordinary system randomness), it must be distinct from body to accomplish this. Both substance and property dualism offer such a distinction, and those particular models thereof that are not causally inert with respect to the physical world provide a basis for illustrating incompatibilist free will (i.e. interactionalist dualism and non-reductive physicalism).
