David Bentley Hart, in his essay “Christ and Nothing”, offers an eloquent condemnation of the modern idolatry of the unconstrained will which chooses morals according to preference:
It seems to me much easier to convince a man that he is in thrall to demons and offer him manumission than to convince him that he is a slave to himself and prisoner to his own will. Here is a god more elusive, protean, and indomitable than either Apollo or Dionysus; and whether he manifests himself in some demonic titanism of the will, like the mass delirium of the Third Reich, or simply in the mesmeric banality of consumer culture, his throne has been set in the very hearts of those he enslaves. And it is this god, I think, against whom the First Commandment calls us now to struggle.
If you aren’t familiar with Hart, I encourage you to take a look at the full article. It takes a few sittings to get through, but is a brilliant commentary on modernism as a reaction to Christianity.
