“Enlightenment is man’s emergence from his self-incurred immaturity.”

What can I know? What ought I to do? What can I hope?

Dignity is a value that creates irreplaceability.

Give me matter, and I will construct a world out of it!

Enlightenment is man’s emergence from his self-imposed immaturity. Immaturity is the inability to use one’s understanding without guidance from another.

The history of nature, begins with good, for it is God’s work; the history of freedom begins with badness, for it is man’s work.

Nothing is divine but what is agreeable to reason.

If the truth shall kill them, let them die.

Experience may teach us what is, but never that it cannot be otherwise.

It is beyond a doubt that all our knowledge begins with experience.

Man must be disciplined, for he is by nature raw and wild.

Treat people as an end, and never as a means to an end.

Experience without theory is blind, but theory without experience is mere intellectual play.

We are enriched not by what we possess, but by what we can do without.

For peace to reign on Earth, humans must evolve into new beings who have learned to see the whole first.

Freedom is the opposite of necessity.

A new idea is delicate. It can be killed by a sneer or a yawn; it can be stabbed to death by a quip and worried to death by a frown on the right man’s brow.

I couldn’t help wondering if that was what God put me on Earth for–to find out how much a man could take without breaking.

I have seen men, choose violence time after time. And in turn, I have seen violence choose them.

The wise man sets bounds even to his innocent desires.

Many a man has met death from the rushing flood of his own eloquence; others from the strength and wondrous thews in which they have trusted.

An avaricious man might be tempted to betray the interests of the state for the acquisition of wealth.

“No” is such a controversial word. Clear, resounding when uttered by men. By women, Low, muffled. Sounds like “yes.”

Freedom has its life in the hearts, the actions, the spirit of men and so it must be daily earned and refreshed – else like a flower cut from its life-giving roots, it will wither and die.
