Actual world
The world as it is. The actual world is a poccible world, specfically the one we live in.
Argument from analogy
The argument that I can use the behaviour of other people to infer that they have minds because they behave as I do, and I have a mind.
Aquinas’ First Way
A form of cosmological argument presented by Aquinas, said to be from ‘motion’. By ‘motion’, Aquinas means ‘change’ from the porential to actual state of something. Such change must be caused by something that is already actual. If the cause was previously potential, then it must in turn have been caused to become actual. There must be a ‘first cause’ of change in this sequence, a cause that is not itself changed from actual to potential. This is God.
Aquinaas’ Second Way
A form of cosmological argument presented by Aquinas, said to be from ‘atemporal’ or ‘sustaining’ causation. As nothing depends on itself, things are sustained in their continued existence. Therefore, there must be a first sustaining cause, which does not depend on any other cause. This is God.
Aquinas’ Third Way
A form of cosmo;ogical argument from contingency by Aquinas. Anything that exists contingently, at some time does not exist. If everything exists contingently, then at some point time does not exist. If nothing existed, then nothing could begin to exist. Therefore, something must exist necessarily, not contigently. This is God.
‘Hard’ behaviourism
Hempel’s version of philosophical behaviourism that claims that statements containing mentla concepts can be reduced or translated into statements about behaviour and physical.
Methodological behaviourism
The theory that claims that because science can only investigate what is publicly accessible, psychology is concerned only with the explanation and prediction of behaviour an.
Philosophical behaviourism
The family of theories that claim that our talk about the mind can be analysed in terms of talk about behaviour. The meaning of our mental concepts is given by behaviour and behavioural dispositions. Also known as ‘logical’ behaviourism.
‘Soft’ behaviourism
Ryle’s version of philosophical behaviourism that claims that our talk of the mind is talk of how someone does or would behave under certain conditions. However, behavioural dispositions are not reducible to a finite set of statements about how someone would behave, nor to a set of statements containing no mental concepts.
Blik
An attitude or view of the world that is not held or withdrawn on the basis of empirical evidence.
Category mistake
Treating a concept as belonging to a logical category that it doesn’t belong to, e.g. ‘this number is heavy’ commits a category mistake as numbers are not the sorts of things that can have weight.
Causal closure
Another term for the completeness of physics.
Causal principle
The claim that everything that exists has a cause.
China thought experiment
A thought experiment presented by Block, presented as an objection to functionalism. If the population of China, using radios, duplicated the functioning of your brain, would this create conscious experiences (just as your brain does)? If not, functionalism (about consciousness) is false.
Cognitive
Language or thought that can be true or false and aims to express how things are.
Compatibilism
The theory that the causal determination of human conduct is consistent with the freedom required for responsible moral agency.
Completeness of physics
The thesis that every physical event has a sufficient physical cause that brings it about in accordance with the laws of physics. Also known as causal closure.
Conceivability argument
Arguments for dualism from conceivability of mind and body being distinct. Descartes argues that:
1) It is conceivable that the mind can exist without the body
2) Conceivability entails possibility
3) It is possible that the mind can exist without the body
Therefore the mind and the body are distinct substances. The zombie argument is a form of conceivability argument for property dualism.
Conceivable
Capable of being imagined or grasped mentally without incoherence or contradiction.
Consciousness
The subjective phenomenon of awareness of the world and/or of one’s mental states.
Easy problem of consciousness
The problem of analysing and explaining the functions of consciousness, e.g. that we can consciously control our behaviour, report on our mental states, and focus on our attention. According to Chalmers, it is ‘easy’ to provide a successful analysis of these facts in physical and/or functional terms.
Hard problem of consciousness
The problem of analysing and explaining the phenomenal properties of consciousness, what it is like to undergo conscious experiences. According to Chalmers, it is ‘hard’ to provide a successful analysis of these properties in physical and/or functional terms.
Contingent existence
The type of existence had by a being, such as human beings, that can exist or not exist.
Correlation
A relationship between two things whereby one always accompanies the other, e.g. the properties of size and shape are correlated. Correlation should be distinguished from identity.
Cosmological argument
Arguments for God’s existence that claim that unless God exists, the question ‘why does anything exist?’ is unanswerable. Oversimplified, arguments from causation claim that everything must have a cause, and causal chains cannot be infinite so there must be a first cause. Arguments from contingency claim that every contingent thing must have an explanation for it’s existence, and this can ultimately only be provided by something that exists necessarily.
Free will defence
An argument to show that there is no inconsistency between the existence of evil and the existence of God, because it if possible that God would allow evils to arise from free will in order that we (or other beings) can have free will.
Design argument
Arguments for God's existence that claim that there is complexity in the world that is evidence of design, and design requires a designer, which is God. The evidence of design that is appealed to is usually the organisation of parts for a purpose or temporal regularities expressed by the laws of nature. Also known as teleological arguments.
Determinism
Commonly understood as the claim that everything that happens, including each human choice and action, has a cause, in accordance with laws of nature. Many philosophers argue that given a particular cause, only one outcome is possible.
Disposition
How something or someone will or is likely to behave under circumstances: what it or they would do, could do, or is liable to do in particular situations or under particular conditions that they are not in at the moment. For example, sugar is soluble (it tends to dissolve when placed in water) while someone who has a friendly disposition tends to smile when they are smiled at.
Interactionist dualism
The theory that mental and physical events can cause one another even though the mind and the body are distinct substances (interactionist substance dualism) or mental and physical properties are distinct fundamental properties (interactionist property dualism).
Property dualism
The theory that there is only one kind of substance, physical substance, but two ontologically fundamental types of property - mental properties and physical properties.
Substance dualism
The theory that two kinds of substance exist, mental substance and physical substance.
Elimination
Ceasing to use a concept on the grounds that what it refers to does not exist. E.g. the idea of ‘caloric fluid’ was eliminated by a new theory of heat as molecular motion.
Eliminative materialism
The theory that at least some of our basic mental concepts, such as consciousness or intentionality, are fundamentally mistaken and should be abandoned, as they don’t refer to anything that exists.
Epiphenomenalism
The theory that mental states and events are epiphenomena, by-products, the effects of some physical process, but with no causal influence of their own. Often combined with property dualism.
Eschatological
The study (-ology) of the ‘last things’ (Greek eskhatos) - death, the final judgement, and the ultimate destiny of human beings.
Eternal
Timeless (atemporal). What is eternal cannot have a beginning or end.
Euthyphro dilemma
Does God will what is morally good because it is good, or is it good because he wills it? If the former, God is not omnipotent, if the latter, morality is arbitrary and ‘God is good’ is tautologous.
Everlasting
Existing throughout all time, without beginning or end.
Moral evil
Bad things that arise as a result of the actions of free agents, e.g. murder.
Natural evil
Bad things, especially pain or suffering, that arise as a result of natural processes, e.g. people dying in earthquakes.
Falsifiable
A claim that is logically incompatible with some (set of) empirical evidence.
Falsification principle
A claim is meaningful only if it is falsifiable, i.e. it rules out some possible experience.
Fatalism
The view that human choice and action makes no (important) difference to what will happen in the future.
Folk psychology
A body of knowledge or theory regarding the prediction and explanation of people’s behaviour constituted by the platitudes of the mind ordinary people are inclined to endorse, i.e. ‘if someone is thirsty, they will normally try to find something to drink’.
Free will
The capacity of rational agents to choose a course of action from among various alternatives.
Function
A mapping from each of the possible inputs to some state to its output. The description of a state’s function describes what that state does.
Functionalism
The theory that mental states are (can be reduced to) functional states, i.e. what it is to be a mental state is just to be a state with certain input and output relations to certain stimuli, behaviour, and other mental states.
Functionalism, causal role
The version of functionalism that interprets the function of mental states in terms of the role they play in a network of causes and effects. The mental state can be ‘realised’ by any state that plays that causal role.
Ghost in the Machine
Ryle’s name for substance dualism
Idealism
The theory that minds are the only kind of substance. Therefore, all that exists are minds and what depends on them (ideas).
Incompatibilism
The belief that determinism and free will cannot both be true. If human beings have free will, determinism is false; if determinism is true, human beings do not have free will.
Indefinitely heterogenous dispositions
Dispositions that can be manifested in many, many different ways. Ryle argued that mental states are indefinitely heterogeneous behavioural dispositions, so that while mental concepts can be analysed in terms of behaviour, they cannot be reduced to talk about behaviour.
Indiscernibility of identicals
Leibniz’ principle that if two things are identical (i.e. are just one thing") then they share all their properties and are so indiscernible, i.e. you cannot have numerical identity without qualitative identity.
Indivisibility argument
Descartes’ argument that bodies are divisible into spacial parts, but minds have no such parts. Therefore, the mind is a distinct substance from the body.
Intentionality
The property of mental states whereby they are ‘directed’ towards an ‘object’, that is they are ‘about’ something; e.g. the belief that Paris is the capital of France is about Paris and the desire to eat chocolate is about chocolate.
Conceptual interaction problem
The objection to interaction dualism that mind and body (mental and physical properties) cannot interact causally, because they are too different in nature, e.g. the mind is outside of space while the body is space.
Empirical interaction problem
The objection to interactionalist dualism that the claim that the mind or mental states cause changes to the body or physical states conflicts with scientific theory or evidence, e.g. hat the total energy in the universe stays constant.
Intrinsic/extrinsic
Distinction in the properties of things. The intrinsic properties of a thing are those which it has in and of itself, e.g. the size of a physical object. Its extrinsic (or relational) features are those which it has only in relation to something else, e.g. the function of a mental state.
Introspection
Direct, first-personal awareness of ones own mental states.
Inverted qualia
The thought experiment that supposes that two people experience subjectively different colours when looking at the same object, but otherwise think and behave in identical ways; e.g. they both call the same object ‘red’. The argument is presented as an objection to a functionalist account of phenomenal consciousness.
