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.

What might be said of things in themselves, separated from all relationship to our senses, remains for us absolutely unknown.

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.

Without man and his potential for moral progress, the whole of reality would be a mere wilderness, a thing in vain, and have no final purpose.

Give me matter and I will build a world out of it.

The possession of power inevitably spoils the free use of reason.

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

What’s courage? Letting love in.

You’ve got to jump off cliffs and build your wings on the way down.

Living at risk is jumping off the cliff and building your wings on the way down.

Life wants us to succeed if only we have the courage to listen.
