“The man has the possibilities of getting free gradually from the mechanical laws.”

Personality in man is what is “not his own” . . . what come from outside, what he has learned, or reflects, all traces of exterior impressions left in the memory.

Would a CONSCIOUS human being destroy himself through war, and crime, and quarrels? No, a man simply knows not what he does to himself.

Man must use what he has, not hope for what is not.

What is possible for individual man is impossible for the masses.

The first reason for people’s slavery is our ignorance, and above all, our ignorance of ourselves.

There is a cosmic law which says that every satisfaction must be paid for with a dissatisfaction.

Humanity is moving in a circle. The progress in mechanical things of the past hundred years has proceeded at the cost of losing many other things which perhaps were much more important for it.

A miracle is not the breaking of physical laws, but rather represents laws which are incomprehensible to us.

Real love is a cosmic force which goes through us. If we crystallize it, it becomes the greatest power in the world.

That which is easy is bad for your inner life.

Time began when you were born. It will end when you die.

Sincerity is the key which will open the door through which you will see your separate parts, and you will see something quite new. You must go on trying to be sincere. Each day you put on a mask, and you must take it off little by little.

One of the strongest motives for wishing to work on yourself is the realization that you may die at any moment – only you must first realize this.

To know means to know all. Not to know all means not to know. In order to know all, it is only necessary to know a little. But, in order to know this little, it is first necessary to know pretty much.

Religion is doing; a man does not merely think his religion or feel it, he ‘lives’ his religion as much as he is able, otherwise it is not religion but fantasy or philosophy.

All who have come to me must have enema each day.

In 1924, I became a Dozent in Gottingen and worked out the quantum mechanics during a holiday stay on Heligoland.

I was 17 and just learning what high fidelity was, what good sound was, and learning the mechanics of tape machines.

This is the reason why quantum mechanics seems so foreign to our everyday existence.

Certainly we do not need quantum mechanics for macroscopic objects, which are well described by classical physics.

The development of quantum mechanics early in the twentieth century obliged physicists to change radically the concepts they used to describe the world.

The true secret to genius is in creativity, not in technical mechanics.

[Heisenberg’s seminal 1925 paper initiating quantum mechanics marked] one of the great jumps-perhaps the greatest-in the development of twentieth century physics.

Once you have your practice and you have your mechanics, you must be able to go out there and trust your mechanics.
