“But only he who, himself enlightened, is not afraid of shadows.”

“But to unite in a permanent religious institution which is not to be subject to doubt before the public even in the lifetime of one man, and thereby to make a period of time fruitless in the progress of mankind toward improvement, thus working to the disadvantage of posterity - that is absolutely forbidden. For himself (and only for a short time) a man may postpone enlightenment in what he ought to know, but to renounce it for posterity is to injure and trample on the rights of mankind.”

“Enlightenment is man's exodus from his self-incurred tutelage. Tutelage is the inability to use one's understanding without the guidance of another person..'Dare to Know'(sapere aude) Have the courage to use your own understanding;this is the motto of the Enlightenment.”

“One who makes himself a worm cannot complain afterwards if people step on him.”

“Enlightenment is man's release from his self incurred tutelage.Tutelage is man's inability to make use of his understanding without direction from another. Self-incurred is this tutelage when its cause lies not in lack of reason but in lack of resolution and courage to use it without direction from another. " Have courage to use your own reason" that's the motto of enlightenment .”
