Scientific truth is universal, because it is only discovered by the human brain and not made by it, as art is.

Evil, by definition, is that which endangers the good, and the good is that which we perceive as a value.

I believe that present day civilized man suffers from insufficient discharge of his aggressive drive.

I believe that both art and the human striving for cognitive comprehension are manifest forms of the grand game in which nothing more is stipulated than the game's rules; both art and actively solicited perceptions are but special cases of the recurring creative act to which we owe our existence.

One could not be a successful scientist without realizing that, a goodly number of scientists are not only narrow-minded and dull, but also just stupid.

Few animals display their mood via facial expressions as distinctly as cats.

Philosophers are people who know less and less about more and more, until they know nothing about everything. Scientists are people who know more and more about less and less, until they know everything about nothing.

In science, new ideas are at first completely neglected,

Hatred of humanity and love of animals make a very bad combination.

Every danger loses some of its terror once its causes are understood.

A man sufficiently gifted with humor is in small danger of succumbing to flattering delusions about himself, because he cannot help perceiving what a pompous ass he would become if he did.

He who has seen the intimate beauty of nature cannot tear himself away from it again. He must become either a poet or a naturalist and, if his eyes are keen and his powers of observation sharp enough, he may well become both.

No such thing as a false analogy exists: an analogy can be more or less detailed and hence more or less informative.

I see the creative accomplishments of which highly gifted humans are capable as special cases of the universal creative process, that game played by everyone against everyone else, from which wells up all that has never been before.

It ought to be realized by all dog owners that obesity shortens a dog's life quite considerably, a life which is much too short anyhow.

All too willingly man sees himself as the centre of the universe, as something not belonging to the rest of nature but standing apart as a different and higher being. Many people cling to this error and remain deaf to the wisest command ever given by a sage, the famous Know thyself inscribed in the temple of Delphi.

From a neighbour, I got a one-day-old duckling and found, to my intense joy, that it transferred its following response to my person. At the same time, my interest became irreversibly fixated on water fowl, and I became an expert on their behaviour even as a child.

Man appears to be the missing link between anthropoid apes and human beings.
