“Laziness and cowardice are the reasons why so great a portion of mankind, after nature has long since discharged them from external direction (naturaliter maiorennes), nevertheless remains under lifelong tutelage, and why it is so easy for others to set themselves up as their guardians. It is so easy not to be of age. If I have a book which understands for me, a pastor who has a conscience for me, a physician who decides my diet, and so forth, I need not trouble myself. I need not think, if I can only pay - others will easily undertake the irksome work for me.That the step to competence is held to be very dangerous by the far greater portion of mankind...”

“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. Sapere aude! 'Have courage to use your own reason!'- that is the motto of enlightenment.”

And since the costs related to maintaining peace will in this way finally become greater than those of a short war, standing armies are the cause of wars of aggression that are intended to end burdensome expenditures. Moreover, paying men to kill or be killed appears to use them as mere machines and tools in the hands of another (the nation), which is inconsistent with the rights of humanity.”

“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.”

“The schematicism by which our understanding deals with the phenomenal world ... is a skill so deeply hidden in the human soul that we shall hardly guess the secret trick that Nature here employs.”
