I have no doubt that philosophers such as Quine enjoyed their mental calisthenics. But they fiddled while Rome burned. Their successors must rally to the colours. The linguistic analysts must deconstruct the new authoritarians. Epistemologists must reveal politicians' speech codes that appear devoid of meaning.
Nobody expects philosophers to agree, any more than do economists or political scientists.
They merely need to make their voices heard. He should dare to make the earth move.
