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.

Some suggestions for you :

Barking dogs occasionally bite, but laughing men hardly ever shoot.

I have found the missing link between the higher ape and civilized man; it is we.

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

It is a good morning exercise for a research scientist to discard a pet hypothesis every day before breakfast. It keeps him young.

I grew up in the large house and the larger garden of my parents in Altenberg. They were supremely tolerant of my inordinate love for animals.

Historians will have to face the fact that natural selection determined the evolution of cultures in the same manner as it did that of species.

Truth in science can be defined as the working hypothesis best suited to open the way to the next better one.

Whenever we find, in two forms of life that are unrelated to each other, a similarity of form or of behaviour patterns which relates to more than a few minor details, we assume it to be caused by parallel adaptation to the same life-preserving function.

There is indeed the possibility that the evolutionary process has, in gray antiquity, bred into us an excess of aggression.

In the course of evolution, it constantly happens that, independently of each other, two different forms of life take similar, parallel paths in adapting themselves to the same external circumstances.

I owe undying gratitude to my patient parents.

The father-mother family with two children isolated in a city flat is already insufficient.

Every man gets a narrower and narrower field of knowledge in which he must be an expert in order to compete with other people. The specialist knows more and more about less and less and finally knows everything about nothing.

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