Metaphysics I: Free Will

This is Unit Four of Philosophy: the first metaphysics unit, on free will. Almost everyone holds two beliefs that sit badly together. Choices feel genuinely up to us. And every event, including everything happening inside a person, looks like the product of what came before it. Both convictions are hard to abandon, and they resist each other. Note what the problem is not. Nobody in this unit denies that people deliberate, weigh options, and decide. The question is what deciding would have to be for the word "free" to be earned. Three answers get built: the two cannot both hold, so drop one; the two cannot both hold, so drop the other; or they can both hold once freedom is understood properly. That third answer is the most popular among philosophers, and all of its work happens inside the word "properly". By the end you will be able to do five things. One: tell determinism from fatalism, and say why they get run together. Two: state the argument that powers the incompatibilist case, and say what it proves and what it leaves open. Three: say why undetermined choices do not by themselves buy freedom. Four: state the principle that blame seems to require, and the case built to break it. Five: place any thinker on the map with three questions.

Four entries setting up the collision. The thesis on one side, the doctrine people mistake it for — and the mistake matters, because the two recommend opposite behaviour — and then the denial of the thesis, which turns out not to help as much as expected.

The collision.

Philosophy 0145 The Problem of Free Will

You chose breakfast this morning. Follow the choice back through mood, habit, upbringing and biology, and it starts to look like something that happened rather than something you did.

The thesis.

Philosophy 0146 Determinism

Every event, decisions included, settled by the prior state of things together with the laws. Given the world a century ago and the physics, a sufficient calculator could in principle have named your breakfast.

And the doctrine it is not.

Philosophy 0147 The Fatalism Confusion

One says the outcome arrives whatever you do; the other says the outcome arrives through what you do. The first skips the appointment. The second keeps it, because treatment is one of the causes.

The denial of the thesis.

Philosophy 0148 Indeterminism

Some events may be fixed by nothing — an individual atom's decay having no prior cause setting the moment. But hold the celebration: an undetermined decision might be random rather than yours, which is a problem two topics ahead.

The first answer, and the argument behind it. That argument is the strongest thing in the unit, and it is worth being precise about what it does: it argues a conditional, and it leaves the condition open for someone else to settle.

The claim.

Philosophy 0150 Incompatibilism

If every choice was settled before you existed, no choice is yours. Two exits follow from accepting that — abandon freedom, or abandon the fixing — and the camp divides between them.

The engine.

Philosophy 0151 The Consequence Argument

Nobody controls the distant past or the laws of nature. If today's act follows from both, then today's act is not up to anyone either. Note that this argues the conditional — it never establishes that the condition holds.

Both exits, and the price of each. One abandons a conviction most people cannot shake. The other keeps it and immediately meets an objection that is harder than it looks — because the thing that rescues openness threatens to remove ownership.

The first exit.

Philosophy 0152 Hard Determinism

Both claims accepted, so freedom goes — and praise and blame need rebuilding the way lightning was rebuilt once its causes were known. The position does not say deliberating is pointless; it says the deliberating is caused too.

The second exit.

Philosophy 0153 Libertarianism (Metaphysical)

Freedom is kept, so the fixing must be false — at the fork, both directions remain available until the person settles it. Note the word: this shares nothing with the political doctrine that sounds the same.

The objection waiting there.

Philosophy 0154 The Randomness Objection

A decision settled by nothing at all — not your character, not your reasons — is a decision nobody made. Chance secures the openness and takes the ownership with it, which is the wrong trade.

The answer, and its cost.

Philosophy 0155 Agent Causation

The person does the causing — not earlier events, and not chance. One writer called such an agent a mover that nothing moved. Critics ask what that amounts to beyond giving the mystery a name.

The most widely held position, and the one that changes the question instead of answering it: perhaps freedom never required an uncaused choice, only the right kind of caused one. Then the objection that presses hardest, and a repair that moves the whole question inside the person.

The move.

Philosophy 0158 Compatibilism

The two claims can hold together, because what freedom demands was misdescribed. Surveys find this the majority view among professional philosophers — and every difficulty in it lives in how the redescription is done.

The first version.

Philosophy 0159 Classical Compatibilism

Free means caused by your own desires without external compulsion. The prisoner is not free and the diner choosing dessert is, whatever the causal history behind the wanting.

The objection.

Philosophy 0160 The Manipulation Objection

Someone implants the wants, and the victim then acts on them willingly. That satisfies the definition and nobody calls it free — and the objection presses that ordinary causal history differs only in having no one behind it.

The repair.

Philosophy 0161 Hierarchical Freedom

You act freely when the desire moving you is one you endorse. The addict who hates his craving and the addict at peace with his behave identically and differ in freedom. The account admits the obvious follow-up: who endorses the endorsing?

Now what the whole debate was for. One principle every position keeps, one principle that sounded undeniable, and a case designed to break the second while leaving the first standing — followed by a move that questions whether any of this needed settling first.

The shared principle.

Philosophy 0165 Responsibility Requires Control

Praise and blame only apply where something was up to the person. Nobody is held responsible for a sneeze. Every position ahead keeps this and disagrees about what satisfies it.

The one that sounded undeniable.

Philosophy 0166 The Principle of Alternative Possibilities

Responsibility requires that the person could have acted otherwise — blame seeming to need an available alternative that was passed over. Stated plainly it is very hard to doubt.

And the case built to break it.

Philosophy 0167 Frankfurt Cases

A hidden mechanism stands ready to force the act if the person shows signs of wavering. He does not waver, so it never activates. He could not have done otherwise, and blame still lands on him.

A different move entirely.

Philosophy 0168 Reactive Attitudes

Resentment and gratitude are built into how people live with each other, and need no metaphysical permission to continue. Critics reply that this relocates the question rather than closing it — whether attitudes can settle what is warranted.

One entry, and it is the unit's most uncomfortable position, because it declines both exits: whichever way the metaphysics goes, the control that responsibility needs is not delivered.

The position.

Philosophy 0169 Free Will Skepticism

Settled choices trace back to what you were given; unsettled ones trace to luck. Either way the ultimate control goes missing. Its defenders do not abandon justice — many argue for protective confinement and forward-looking blame instead.

One experiment gets cited in this debate more than everything else combined, usually as though it had settled something. It is worth knowing precisely what was measured, and the three separate grounds on which the popular reading is disputed.

The experiment.

Philosophy 0170 Neuroscience and the Libet Experiments

Brain activity indicating readiness appeared before people reported becoming aware of deciding to move. The popular reading has the brain deciding first — and it is contested on the timing reports, on what the signal means, and on whether flexing a wrist resembles a decision at all.

One procedure to close, and its value is practical: thinkers in this area use the same words for different things, so the classification runs on what someone answers rather than on what they call themselves.

Three questions, in order.

Philosophy 0175 Classifying a Free-Will Position

Ask whether they take the world to be settled by prior causes, whether they think freedom could survive that, and whether they think anyone has it. The three answers locate anyone — and classify from the answers, because the word "freedom" is used for three different things here.

Five things you can now do. You can tell determinism from fatalism: one says outcomes come about through what you do, the other says they arrive regardless — which is why one of them skips the appointment and the other keeps it. You can state the consequence argument — nobody controls the distant past or the laws — and say that it argues a conditional and leaves the condition for someone else to settle. You can say why undetermined choices do not buy freedom on their own: a decision settled by nothing, including your own reasons, is one nobody made. You can state the principle that blame requires an available alternative, and the case that breaks it — a device ready to force the act that never has to. And you can place any thinker with three questions, classifying from their answers rather than from the word they use for themselves.
