This is the highest wisdom that I own; freedom and life are earned by those alone who conquer them each day anew.

Time does not relinquish its rights, either over human beings or over mountains.

If we examine every stage of our lives, we find that from our first breath to our last we are under the constraint of circumstances. And yet we still possess the greatest of all freedoms, the power of developing our innermost selves in harmony with the moral order of the universe, and so winning peace of heart whatever obstacles we meet.

One should not search for anything behind the phenomena. They themselves are the message.

Men are so constituted that every one undertakes what he sees another successful in, whether he has aptitude for it or not.

With the growth of knowledge our ideas must from time to time be organized afresh. The change takes place usually in accordance with new maxims as they arise, but it always remains provisional.

Whatever is the lot of humankind I want to taste within my deepest self. I want to seize the highest and the lowest, to load its woe and bliss upon my breast, and thus expand my single self titanically and in the end go down with all the rest.
