Intellect distinguishes between the possible and the impossible reason distinguishes between the sensible and the senseless. Even the possible can be senseless.

Something which is against natural laws seems to me rather out of the question because it would be a depressive idea about God. It would make God smaller than he must be assumed. When he stated that these laws hold, then they hold, and he wouldn't make exceptions. This is too human an idea. Humans do such things, but not God.

I believe there is no philosophical high-road in science, with epistemological signposts. No, we are in a jungle and find our way by trial and error, building our road behind us as we proceed.

The human race has today the means for annihilating itself--either in a fit of complete lunacy, i.e., in a big war...or by the careless handling of atomic technology, through a slow process of poisoning and of deterioration in its genetic structure.

Physics as we know it will be over in six months.

It is true that many scientists are not philosophically minded and have hitherto shown much skill and ingenuity but little wisdom.

Those who say that the study of science makes a man an atheist, must be rather silly people.

The belief that there is only one truth and that oneself is in possession of it seems to me the deepest root of all evil that is in the world.

But in practical affairs, particularly in politics, men are needed who combine human experience and interest in human relations with a knowledge of science and technology.

We need to make a world in which fewer children are born, and in which we take better care of them.

Science?is so greatly opposed to history and tradition that it cannot be absorbed by our civilization.

No language which lends itself to visualizability can describe quantum jumps.

The problem of physics is how the actual phenomena, as observed with the help of our sense organs aided by instruments, can be reduced to simple notions which are suited for precise measurement and used of the formulation of quantitative laws. Experiment and Theory in Physics

The difficulty involved in the proper and adequate means of describing changes in continuous deformable bodies is the method of differential equations. ... They express mathematically the physical concept of contiguous action. Einstein's Theory of Relativity
