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

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

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.

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

We do not take humor seriously enough.

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

We had better dispense with the personification of evil, because it leads, all too easily, to the most dangerous kind of war: religious war.

Most of the vices and mortal sins condemned today correspond to inclinations that were purely adaptive or at least harmless in primitive man.

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

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

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

The bond with a true dog is as lasting as the ties of this earth will ever be.

'I don't need brains,' says the billionaire contemptuously. 'I'm brainy enough myself!' The broker cries out in desperation, 'What, in heaven's name, do you want?' 'Goodness,' is the answer.

Ethologists are often accused of drawing false analogies between animal and human behaviour. However, no such thing as a false analogy exists: an analogy can be more or less detailed and, hence, more or less informative.

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.

I consider early childhood events as most essential to a man's scientific and philosophical development.

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.

I owe undying gratitude to my patient parents.

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.

Practically all animals which move fast in a homogeneous medium have found means of giving their body a streamlined shape, thereby reducing friction to a minimum.

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

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

When I was about ten, I discovered evolution by reading a book by Wilhelm Boelsche and seeing a picture of Archaeopteryx.

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.

The human mind in taking us down the path of technocracy has become the adversary of life itself and collaterally the adversary of the human soul.

Man has been driven out of the paradise in which he could trust his instincts.

The cat is a wild animal that inhabits the homes of humans.

The bond with a dog is as lasting as the ties of this earth can ever be

I did work out every day. I needed it to have the endurance to do what needed to be done and not get hurt. I have such a new respect for action stars now.

I mean the only thing that is hopefully good about us is after the arguments we can actually still face each other the next day or the day after and talk about something else and sort of get over it.

My favorite singer to this day is Nat King Cole. I've tried to emulate his phrasing. It is so absolutely beautiful to listen to his lovely voice.

I want to have babies one day but not right now. When I do it I want to do it really well. I want it to be my best project in life.

I think I've become a much better singer and a much better player. Years and years of playing a couple of hours every day will do that.

I am tomorrow, or some future day, what I establish today. I am today what I established yesterday or some previous day.

I just wrote one song at a time. Kinda like an alcoholic. One day at a time.

Working mothers do an hour more per day than working fathers do and working mothers do on average an hour more per day with the kids than working fathers do.

When it is time to get to work, I go away completely and don't do anything except the work. And that can be 16 hours a day.

George Pal had total control, and he was there on the set every day. You never met a more charming man in your entire lifetime - what a lovely gentleman.

I'll tell you what I did need to learn was tolerance, and I think I've been actually given a daily opportunity to practice that, and it's - it's - and I know that that sounds almost like a backhanded slap, and it is in a way because I haven't been successful at it every day.

Since the beginning, I always loved the game. When you grow up in Montreal, one day you want to be a professional hockey player. When I was six or seven, I knew that was what I wanted.

Depending on what day of the week it is and what time of the month it is, I'm a good friend or not a good friend. I'm more or less a good mom or not a good mom, more or less a good mate or not a good mate. That's just life, whether or not you're public.

Even if you walk exactly the same route each time - as with a sonnet - the events along the route cannot be imagined to be the same from day to day, as the poet's health, sight, his anticipations, moods, fears, thoughts cannot be the same.

A play is much easier to maintain your personal life with because if you're rehearsing, you're working like from 11 to 6 or 11 to 5 and you get to have your whole morning and your whole evening. When you're doing the play, you have all day.

I'd like to one day play Amanda, the mother, in The Glass Menagerie.

Even a stopped clock is right twice a day.

I'm working harder than ever now, and I'm putting on my pants the same as I always have. I just get up every day and try to do a little better than the day before, and that is to run a great restaurant with great food, great wine, and great service. That's my philosophy.

Failure happens all the time. It happens every day in practice. What makes you better is how you react to it.

The day cold and fair with a high easterly wind: we were visited by two Indians who gave us an account of the country and people near the Rocky mountains where they had been.
