Every man is in his own person the whole human race without a detail lacking....I knew I should not find in any philosophy a single thought which had not passed through my own head, nor a single thought which had not passed through the heads of millions and millions of men before I was born.
But it was ever thus, all through my life: whenever I have diverged from custom and principle and uttered a truth, the rule has been that the hearer hadn't strength of mind enough to believe it.
