You see, wire telegraph is a kind of a very, very long cat. You pull his tail in New York and his head is meowing in Los Angeles. Do you understand this? And radio operates exactly the same way: you send signals here, they receive them there. The only difference is that there is no cat.
This subject brings me to that vilest offspring of the herd mind -- the odious militia. The man who enjoys marching in line and file to the strains of music falls below my contempt; he received his great brain by mistake -- the spinal cord would have been amply sufficient. This heroism at command, this senseless violence, this accursed bombast of patriotism -- how intensely I despise them! War is low and despicable, and I had rather be smitten to shreds than participate in such doings.
I cannot seriously believe in it [quantum theory] because the theory cannot be reconciled with the idea that physics should represent a reality in time and space, free from spooky actions at a distance [spukhafte Fernwirkungen].
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.
