A model should be as simple as it can be but no simpler.

If I were wrong, wouldn't one be enough?
-
As an elderly man, I have remained estranged from the society here.

I believe that whoever tries to think things through honestly will soon recognize how unworthy and even fatal is the traditional bias against Negroes. What can the man of good will do to combat this deeply rooted prejudice? He must have the courage to set an example by words and deed, and must watch lest his children become influenced by racial bias.

One cannot learn so well as by experiencing it oneself.
-
It is difficult even to attach a precise meaning to the term "scientific truth." So different is the meaning of the word "truth" according to whether we are dealing with a fact of experience, a mathematical proposition or a scientific theory. "Religious truth" conveys nothing clear to me at all.
-
The State idea is not according to my heart. I cannot understand why it is needed. It is connected with narrow-minded and economic obstacles. I believe it is bad. I have always been against it.
-
The content of scientific theory itself offers no moral foundation for the personal conduct of life.
-
If there was such a thing, in the beginning, God created Newton's laws of motion together with the necessary masses and forces. This is all; everything beyond this follows from the development of appropriate mathematical methods by means of deduction.
-
A conviction akin to religious feeling of the rationality or intelligibility of the world lies behind all scientific work of a high order.
-
Artists and creative workers - people who have accomplished work worthwhile have had a very high sense of the way to do things. They haven't been contented with mediocrity. They haven't confined themselves to the beaten tracks; they have never been satisfied to do things just as others do them, but always a little better. Few are those who see with their own eyesand feel with their own hearts.

My political ideal is democracy. Let every man be respected as an individual and no man idolized.
-
From a certain temperature on, the molecules 'condense' without attractive forces; that is, they accumulate at zero velocity. The theory is pretty, but is there some truth in it.
-
There lies the weaknesss of positivists and professional atheists who are elated because they feel that they have not only successfully rid the world of gods but "bared the miracles." (That is, explained the miracles. - ed.) Oddly enough, we must be satisfied to acknowledge the "miracle" without there being any legitimate way for us to approach it . I am forced to add that just to keep you from thinking that -weakened by age-I have fallen prey to the clergy.
-
Creative energy is more critical than learning.
-
Philosophers play with the word, like a child with a doll.... It does not mean that everything in life is relative.
-
When I think of the most able students I have encountered in my teaching - I mean those who have distinguished themselves not only by skill but by independence of thought - then I must confess that all have had a lively interest in epistemology.
-
You can’t blame gravity for falling in love.
-
The words of language, as they are written or spoken, do not seem to play any role in my mechanism of thought. The physical entities which seem to serve as elements in thought are certain signs and more or less clear images.
-
I feel that you are justified in looking into the future with true assurance, because you have a mode of living in which we find the joy of life and the joy of work harmoniously combined. Added to this is the spirit of ambition which pervades your very being, and seems to make the day's work like a happy child at play.

Failing isn't bad when you learn what not to do.
-
If we think of the field as being removed, there is no 'space' which remains, since space does not have an independent existence.

Qualities I sought in a scientific theory were naturalness, inner perfection and logical simplicity from an aesthetic approach.
