[Max Planck] was one of the finest people I have ever known... but he really didn't understand physics, [because] during the eclipse of 1919 he stayed up all night to see if it would confirm the bending of light by the gravitational field. If he had really understood [general relativity], he would have gone to bed the way I did
The foundation of morality should not be made dependent on myth nor tied to any authority lest doubt about the myth or about the legitimacy of the authority imperil the foundation of sound judgment and action.
Formerly, people thought that if matter disappeared from the universe, space and time would remain. Relativity declares that space and time would disappear with matter.
There is nothing divine about morality; it is a purely human affair. If people are good only because they fear punishment, and hope for reward, then we are a sorry lot indeed. What the individual can do is to give a fine example, and to have the courage to uphold ethical values .. in a society of cynics.
If we trace out what we behold and experience through the language of logic, we are doing science; if we show it in forms whose interrelashionships are not accessible to our conscious thought but we are intuitively recognized as meaningful, we are doing art.
I am not a positivist. Positivism states that what cannot be observed does not exist. This conception is scientifically indefensible, for it is impossible to make valid affirmations of what people 'can' or 'cannot' observe. One would have to say 'only what we observe exists,' which is obviously false.
In two weeks the sheeplike masses of any country can be worked up by the newspapers into such a state of excited fury that men are prepared to put on uniforms and kill and be killed, for the sake of the sordid ends of a few interested parties. Compulsory military service seems to me the most disgraceful symptom of that deficiency in personal dignity from which civilized mankind is suffering today.
Well, I have considered myself to be very fortunate in that I have been able to do mostly only that which my inner self told me to do... I am also aware that I do receive much criticism from the outside world for what I do and some people actually get angry at me. But this does not really touch me because I feel that these people do not live in he same world as do I.
To act intelligently in human affairs is only possible if an attempt is made to understand the thoughts, motives, and apprehension of one's opponent so fully that one can see the world through their eyes.
