TAGORE: I was discussing with Dr. Mendel today the new mathematical discoveries which tell us that in the realm of infinitesimal atoms chance has its play; the drama of existence is not absolutely predestined in character.
EINSTEIN: The facts that make science tend toward this view do not say good-bye to causality.
TAGORE: Maybe not, yet it appears that the idea of causality is not in the elements, but that some other force builds up with them an organized universe.
EINSTEIN: One tries to understand in the higher plane how the order is. The order is there, where the big elements combine and guide existence, but in the minute elements this order is not perceptible.
TAGORE: Thus duality is in the depths of existence, the contradiction of free impulse and the directive will which works upon it and evolves an orderly scheme of things.
EINSTEIN: Modern physics would not say they are contradictory. Clouds look as one from a distance, but if you see them nearby, they show themselves as disorderly drops of water.
TAGORE: I find a parallel in human psychology. Our passions and desires are unruly, but our character subdues these elements into a harmonious whole. Does something similar to this happen in the physical world? Are the elements rebellious, dynamic with individual impulse? And is there a principle in the physical world which dominates them and puts them into an orderly organization?
EINSTEIN: Even the elements are not without statistical order; elements of radium will always maintain their specific order, now and ever onward, just as they have done all along. There is, then, a statistical order in the elements.
TAGORE: Otherwise, the drama of existence would be too desultory. It is the constant harmony of chance and determination which makes it eternally new and living.
EINSTEIN: I believe that whatever we do or live for has its causality; it is good, however, that we cannot see through to it.
