The study of the errors into which great minds have fallen in the pursuit of truth can never be uninstructive. - Charles Mackay

Let us not, in the pride of our superior knowledge, turn with contempt from the follies of our predecessors. The study of the errors into which great minds have fallen in the pursuit of truth can never be uninstructive.

The greatest ladies thither came, And plied in chariots daily, Or pawned their jewels for a sum To venture in the Alley.

You have no enemies, you say? Alas, my friend, the boast is poor. He who has mingled in the fray of duty that the brave endure, must have made foes.

You’ve been a coward in the fight.
