Famous for his arguments for teleological realism.

Derk Pereboom — Pereboom maintains that due to general facts about the nature of the universe, we lack the free will required for the aspect of moral responsibility at issue in the traditional debate. That is, whether our actions are deterministically or indeterministically caused, we will not have the control in action required for our deserving to be blamed or punished for immoral decisions, and to be praised or rewarded

Susan Wolf — Wolf's work centres on the relation between freedom, morality, happiness and meaningfulness in life. Her book Freedom Within Reason argues for a view of free will as the ability to do what one reasonably thinks is the right thing.

Galen Strawson — In the free will debate, Strawson holds that there is a fundamental sense in which free will is impossible, whether determinism is true or not. He argues for this position with what he calls his "basic argument", which aims to show that no-one is ever ultimately morally responsible for their actions, and hence that no one has free will in the sense that usually concerns us.

David Enoch — Enoch defends “Robust Realism”, the view according to which there are objective, universal, non-natural moral truths, truths that when successful in our moral inquiries we discover rather than create, that don’t constitutively depend on us and our dispositions. He is famous for his Agency Shmagency argument.

Frankfurt has rejected the principle of alternative possibilities based on a series of counterexamples, the so-called "Frankfurt cases".

Famous for his concept of Strawsonian reactive attitudes.
