Extract

There is a well-known argument which is an attempt to show that all arguments in favour of determinism are self-defeating. Proponents of the Determinism-Is-Self-Defeating Argument (hereafter referred to as DISDA) claim that all pro-deterministic arguments, if successful, undermine rationality and epistemic justification. Indeed, the proponents of DISDA claim that since the truth of determinism implies that we cannot claim to know the truth of any proposition, then it follows, of course, that proponents of determinism cannot claim to know that determinism is itself true. Hence, the self-defeating nature of determinism.

Kant states: “But we cannot possibly conceive of a reason as being consciously directed from outside in regard to its judgments; for in that case the subject would attribute the determination of his power ofjudgment, not to his reason, but to an impulsion. Reason must look upon itself as the author of its own principles independently of alien influences. Therefore as practical reason or as the will ofa rational being, it must be regarded by itself as free.” Also, “[B]ut we have been quite unable to demonstrate freedom as something actual in ourselves and in human nature; we saw merely that we must presuppose it if we wish to conceive a being as rational and as endowed with consciousness of his causality in regard to actions…” (116).

Also “the autonomy of intelligence, or of ‘reason’ as we used to say is thus the keystone of the whole edifice. What then does truth owe to freedom? Why everything, of course!” (537).

7 I assume, of course, that in order for an agent to be free from causal compulsion it must be true that in a given situation he could have chosen to do (or believe) otherwise. I also assume that we can gain evidence for freedom (or the lack of it) through introspection.
