I think it’s generally known that one wing of the New Atheism, led primarily by Jerry Coyne, has made the denial of free will a major cause. Well, so have Calvinists! (Just for somewhat different reasons.) I think all aspects of the Great Free Will Debate are illuminated by this wonderful passage from Leszek Kolakowski’s magisterial book on Pascal and the Jansenist controversy, God Owes Us Nothing:
The belief that everything is preordained by God is psychologically compatible with the belief that I am free in my actions. Personal freedom is an irresistible and elementary experience; it is not analyzable any further because of its elementary character. The former belief acts as a source of trust in life: God rules and orders everything, thus everything is directed toward a good outcome, even if we cannot know or see the cunning tactics of providence. This psychological compatibility proves doubtful when exposed to theological scrutiny, and the task is then to make a coherent, logically sound whole out of the two experiences.… The most elementary facts of experience – “I,” existence, freedom – once converted into theoretical concepts, tend to resist logical examination and are therefore threatened with a verdict of theoretical annihilation; indeed, they have on many occasions been denounced as figments of the imagination. Still, they do not vanish from experience; they stubbornly refuse to evaporate, all philosophers’ condemnations notwithstanding. To accept all-embracing providence without denying the irresistible experience of freedom is psychologically possible even for people who cannot be accused of having simply failed to learn their first lesson in logic; they do not necessarily feel mental discomfort because they believe in, or experience, both. But to unite both in a consistent “theory” seems hopeless, and when theologians ultimately admit that there is a “mystery” in combining providence and freedom, they do not claim to explain anything, but accept the inadequacy of “human reason.” Rationalists normally shrug off the idea of “mystery” (as distinct from something not yet known) as a verbal cover for simple illogicality. However, when people think of ultimate realities, the experience of mystery, which often includes a logical helplessness, may be intellectually more fruitful than rationalist self-confidence that simply cancels metaphysical questions, relying on doctrinal dogmas. To be sure, we have only one logic at our disposal but we are not sure how far its validity can extend when dealing with those ultimate realities.
