Compatibilism based on ''the Right Stuff'' and the Pereboom rebuttal:
Character-based account: A decision can be said to be “free” if it is caused by, and not out of character for, a particular agent. This is the view traditionally associated with the likes of David Hume. It is probably too simplistic to be useful. Other compatibilist accounts offer more specific conditions.
Second-order desire account: A decision can be said to be free if it is caused by a first-order desire (e.g. I want some chocolate) that is reflexively endorsed by a second-order desire (e.g. I want to want some chocolate). This is the account associated with Harry Frankfurt (and others).
Reasons-responsive account: A decision can be said to be free if it is caused by a decision-making mechanism that is sufficiently responsive to reasons. In other words, if the mechanism had been presented with a different set of reasons-for-action, it would have produced a different decision (in at least some possible worlds). This is the account associated with Fischer and Ravizza, and comes in several different forms (weak, moderate and strong responsiveness).
Moral reasons-sensitivity account: A decision can be said to be free if it is produced by a decision-making mechanism that is capable of grasping and making use of moral reasons for action. This is the account associated with R. Jay Wallace. It is similar to Fischer and Ravizza’s account, but pays particular attention to the role of moral reasons in decision-making.
As you can see, all of these accounts claim that a certain type of causal sequence has the “right stuff” for free will, irrespective of whether the decisions produced are fully determined by those causal sequences.
To put it more formally, Pereboom adopts the following argument against compatibilism:
(1) If one agent's decision is manipulated by another agent, then that first agent's action is not freely willed.
(2) There is no difference between a manipulation by another agent and causation by a causal factor external to the agent.
(3) On determinism, all of an agent's actions are determined (causally influenced) by at least some factors beyond that agent's control.
(4) Therefore, on determinism, no agent can be said to freely will their actions (or be morally responsible for them). (from 1, 2 and 3)
