We often read nowadays of the valor or audacity with which some rebel attacks a hoary tyranny or an antiquated superstition. There is not really any courage at all in attacking hoary or antiquated things, any more than in offering to fight one’s grandmother. The really courageous man is he who defies tyrannies young as the morning and superstitions fresh as the first flowers. The only true free-thinker is he whose intellect is as much free from the future as from the past. He cares as little for what will be as for what has been; he cares only for what ought to be.
