He who joyfully marches to music rank and file, has already earned my contempt. He has been given a large brain by mistake, since for him the spinal cord would surely suffice. This disgrace to civilization should be done away with at once. Heroism at command, how violently I hate all this, how despicable and ignoble war is; I would rather be torn to shreds than be a part of so base an action. It is my conviction that killing under the cloak of war is nothing but an act of murder.
I sometimes ask myself how it came about that I was the one to develop the theory of relativity. The reason, I think, is that a normal adult never stops to think about problems of space and time. These are things which he has thought about as a child. But my intellectual development was retarded,as a result of which I began to wonder about space and time only when I had already grown up.
If the possibility of the spiritual development of all individuals is to be secured, a second kind of outward freedom is necessary. The development of science and of the creative activities of the spirit in general requires still another kind of freedom, which may be characterised as inward freedom. It is this freedom of the spirit which consists in the interdependence of thought from the restrictions of authoritarian and social prejudices as well as from unphilosophical routinizing and habit in general. This inward freedom is an infrequent gift of nature and a worthy object for the individual.
Knowledge of what is does not open the door directly to what should be. If one asks the whence derives the authority of fundamental ends, since they cannot be stated and justifed merely by reason, one can only answer: they exist in a healthy society as powerful traditions, which act upon the conduct and aspirations and judgements of the individuals; they are there, that is, as something living, without its being necessary to find justification for their existence. They come into being not through demonstration but through revelation, through the medium of powerful personalities. One must not attempt to justify them, but rather to sense their nature simply and clearly.
