This man is with us still, free, independent, lovely, powerful, rational, responsible, brave, the hero of many novels and books in moral philosophy. The raison d'être of this attractive but misleading creature is not far to seek.
He is the offspring of the age of science, confidently rational and yet increasingly aware of his alienation from the material universe which his discoveries reveal .
In fact, this man had already received a glorious incarnation nearly a century earlier in the work of Milton: his proper name is Lucifer.
