Enlightenment is man's emergence from his self-imposed nonage. Nonage is the inability to use one's own understanding without another's guidance. This nonage is self-imposed if its cause lies not in lack of understanding but in indecision and lack of courage to use one's own mind without another's guidance. Dare to know!
Playing the part of a charitable soul was only for those who were afraid of taking a stand in life. It is always far easier to have faith in your own goodness than to confront others and fight for your rights. It is always easier to hear an insult and not retaliate than have the courage to fight back against someone stronger than yourself; we can always say we're not hurt by the stones others throw at us, and it's only at night - when we're alone and our wife or our husband or our school friend is asleep - that we can silently grieve over our own cowardice.
As to moral courage, I have very rarely met with the two o'clock in the morning kind. I mean unprepared courage, that which is necessary on an unexpected occasion, and which, in spite of the most unforeseen events, leaves full freedom of judgement and decision.
There is a persuasion in the soul of man that he is here for cause, that he was put down in this place by the Creator to do the work for which he inspires him, that thus he is an overmatch for all antagonists that could combine against him.
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.
