More than any other product of human scientific culture scientific knowledge is the collective property of all mankind.

Natural selection does not give any preference at all to anything that, in the long run, could be advantageous for the species but blindly rewards everything that, momentarily, affords greater procreative success.

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.

The competition between human beings destroys with cold and diabolic brutality... Under the pressure of this competitive fury we have not only forgotten what is useful to humanity as a whole, but even that which is good and advantageous to the individual. [...] One asks, which is more damaging to modern humanity: the thirst for money or consuming haste... in either case, fear plays a very important role: the fear of being overtaken by one's competitors, the fear of becoming poor, the fear of making wrong decisions or the fear of not being up to snuff...

Every mutation through a new combination of genetic factors that provides the organism with a new opportunity for coming to terms with the conditions of its environment signifies no more and no less than that new information about this environment has got into that organic system. Adaptation is essentially a cognitive process.

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.

The fidelity of a dog is a precious gift.
