Free Will and Determinism Revision Powerpoint

Key Words to be happy withFree will – autonomy, freedom to choose on the basis

of reasonScientific worldview - every event has a cause eg

cognitive science (the mind is like a computer)Determinism or necessity – everything is subject to

the laws of cause and effectHard determinism – free will is an illusion because

the will is causally predeterminedCompatibilism – free will is real even though the will

is causally determined: freedom requires determinism.

Libertarianism – free will is a metaphysical idea so freedom and determinism are incompatible.

Key assumptionsHard determinists assume free will means a causally

determined act over which I have no control.Compatibilists assume freedom means “absence of

constraint”.Libertarians assume freedom means “subject to

reason alone”, outside of the scientific realm of cause and effect.

Honderich’s viewpoint

Honderich is a hard determinist.Our wills are causally determined.Freedom means “without strict causal antecedents”.Free will is incompatible with determinism.Therefore we have no free will.

Hume’s viewpointNote: Bowie* incorrectly labels Hume a libertarian.

Hume is a compatibilist or soft determinist.Free will means “absence of constraint”.Constraints could be psychological (eg mental

illness), physical (eg lack of strength) or logical (eg I can’t be in two places at once).

Free will requires necessity (Hume’s word for determinism) for without a cause, our wills would be random.

AJ Ayer is a modern compatibilist (see Freedom and Reason)

Kant’s viewpointKant is a libertarian, and his key assumption is

autonomy (self-rule or freedom with reason).Free will belongs to the realm of ideas (the noumenal

world or world of things in themselves where concepts like space, time and causation exist).

Moral acts can only be moral if they are free, coming from reason alone (a priori reason, meaning before experience).

CA Campbell (1976) is a modern libertarian. He sees freedom at points of struggle with decisions, ie “it could have been otherwise”.

Problems with different viewpoints

Honderich’s view seems to abandon hope for controlling our futures.

Hume’s view seems to take a rather minimal view of freedom (isn’t freedom a power, as Hume himself suggests?). Key question: could I have done otherwise? Honderich says “no”.

Kant’s view seems to divide human experience between the realm of reason, of pure ideas (called the noumenal world), and the realm of cause and effect (which he calls the phenomenal world).

AJ Ayer’s viewAyer (1910-1989) argues that determinism is

misleading idea suggesting “one event is in the power of another” rather than just factually correlated. Caused does not mean forced.

Laws of nature aren’t prescriptive in the way laws of the country are prescriptive....they don’t place eg the human will under obligations. They simply lay down established patterns in the nature of things.

“The laws of mechanics do not compel the planets to move in their orbits; they simply describe planetary motion.” DJ O’Connor , Free Will (1971:73)

Behaviourism and psychologyFreud and Laplace were hard determinists (will and

conscience come from our upbringing)Skinner argues we are conditioned to behave by

experiences (Pavlov’s dog). So we can condition new types of behaviour (eg advertising…where Skinner made a fortune in the USA).

JB Watson argues that if we change people’s environment we can change their behaviour (genes and environment are important).

Some films you could mentionA Clockwork Orange takes a hard determinist view:

we are compelled by both internal and external constraints.

Truman Show starts with Truman inhabiting a hard determinist world where everything is programmed. But Truman uses reason to work this out and break out of John Locke’s locked room (see textbook for Locke’s analogy). So in the end this is a Kantian, libertarian view.
