He is the greatest artist who has embodied, 

in the sum of his works, 

the greatest number of the greatest ideas.

How I hate those who are dedicated to producing conformity.

Our Father which art in heaven

 — Stay there — 

And we will stay on earth

How lovely are the portals of the night, 

when stars come out to watch the daylight die.

Everyone wishes to have truth on his side, 

but not everyone wishes to be on the side of truth.

It's a poor sort of memory that only works backwards.

We live in this world

 in order always 

to learn industriously 

and to enlighten each other 

by means of discussion 

and to strive vigorously 

to promote the progress 

of science and the fine arts.

Man's inhumanity to man makes countless thousands mourn!

Physics is becoming too difficult for the physicists.

Genius is the ability to renew one's emotions in daily experience.

It will be found, in fact, 

that the ingenious are always fanciful, 

and the truly imaginative 

never otherwise than analytic.

It seems as if life and hope must cease together.

When you're finished changing, you're finished.

Feeling is the consciousness of the resulting conditions 

— of success, failure, equilibrium, compromise or balance —

in this continuous rivalry of ideas.

The greatest enemy 

of any one of our truths 

may be the rest of our truths.

There is, I conceive, no contradiction in believing 

that mind is at once the cause of matter 

and of the development of individualised human minds 

through the agency of matter.

Know or listen to those who know.

There is a magnet in your heart that will attract true friends. 

That magnet is unselfishness, 

thinking of others first; 

when you learn to live for others, 

they will live for you.

It's the job that's never started as takes longest to finish.

We cast a shadow on something wherever we stand.

Creativity takes courage.
