Courage becomes a worthwhile and meaningful virtue when it is regarded not so much as a willingness to die manfully but as a determination to live decently.
Persevere in thy quest and thou shalt find what thou seekest. Pursue thy aim unswervingly and thou shalt gain victory. Struggle earnestly and thou shalt triumph.
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.
