How then is perfection to be sought? Wherein lies our hope? In education, and in nothing else.

But a lie is a lie, and in itself intrinsically evil, whether it be told with good or bad intents.

A lie is the abandonment and, as it were, the annihilation of the dignity by man.

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!

By a lie a man throws away and, as it were, annihilates his dignity as a man. A man who himself does not believe what he tells another ... has even less worth than if he were a mere thing. ... makes himself a mere deceptive appearance of man, not man himself.
