The supreme vice is shallowness.
Oscar Wilde: De profundis (1897).
El supremo defecto es la vacuidad.
Hadrian Bagration is a humble and avid reader and perhaps an author. He pleads guilty to a few titles. He is also an enthusiastic but somewhat negligent follower of such intellects as those of the early Sartre, Albert Camus, Harold Bloom, Jorge Luis Borges, the French encyclopaedists, epistemologist Mario Bunge, Richard Dawkins and the insufferable (in today's ludicrous politically correct view) paleontologist Peter Ward. Beyond the above, and besides a vague vital skepticism and abhorrence of the cult of zeal, he is known for being unremarkably collected.
