Everyone knows that humans make decisions; that is a red herring in the debate on free will. The only real controversy here is Libertarian free will.
"Libertarian free will means that our choices are free from the determination or constraints of human nature and free from any predetermination by God. All free will theists hold that libertarian freedom is essential for moral responsibility, for if our choice is determined or caused by anything, including our own desires, they reason, it cannot properly be called a free choice. Libertarian freedom is, therefore, the freedom to act contrary to ones nature, predisposition and greatest desires. Responsibility, in this view, always means that one could have done otherwise."
The objections are (quotes are from theopedia.com):
"\1) Causality If causes are understood as conditions prior to an effect that guarantee an effect, and all events have causes, then it follows that all events were preceded by conditions that guaranteed those events. But this is the same as saying all events are determined. Since the choices of humans are events, it follows that the choices of humans are determined.
\2) Responsibility Rather than salvage human responsibility, some maintain that libertarian freedom destroys it. If our choices have no causes, in what sense are they our choices? Is it any more agreeable to reason to hold humans responsible for choices they didnt cause than to hold them responsible for choices that were caused and thus determined?"
Just as a reminder, this thread is about the above two objections. No one disputes the red herring of compatibilism; it is self evident:
"In compatibilism, free will is affected by human nature and man will never choose contrary to his nature and desires. Man will always do what he desires most at any particular moment - even when there are competing desires."
If you believe in free will, respond to the above two objections under the bolded headings.
