Godlessness is a kind of shameless wickedness which bids defiance to the punishments that the idea of God inspires in us.
Have the courage to use your own understanding! This is the motto of the Enlightenment. What is Enlightenment? (1784)
Enlightenment is man’s emergence from his self-imposed immaturity. Immaturity is the inability to use one’s understanding without guidance from another. This immaturity is self-imposed when its cause lies not in lack of understanding, but in lack of resolve and courage to use it without guidance from another. What is Enlightenment? (1784)
It is so easy to be immature. If I have a book to serve as my understanding, a pastor to serve as my conscience, a physician to determine my diet for me, and so on, I need not exert myself at all. I need not think, if only I can pay: others will readily undertake the irksome work for me. What is Enlightenment? (1784)
