“Darwinian social theory gives us a glimpse of an underlying symmetry and logic in social relationships which, when more fully comprehended by ourselves, should revitalize our political understanding and provide the intellectual support for a science and medicine of psychology. In the process it should also give us a deeper understanding of the many roots of our suffering.”

Preface.
A History of Science Vol.1 Ancient Science Through the Golden Age of Greece (1952)
Context: The history of science should not be an instrument to defend any kind of social or philosophic theory; it should be used only for its own purpose, to illustrate impartially the working of reason against unreason, the gradual unfolding of truth, in all its forms, whether pleasant or unpleasant, useful of useless, welcome or unwelcome.

As quoted in An Indian pilgrim: an unfinished autobiography (1997) by himself, Sisir Kumar Bose, and Sugata Bose, p. 124
Context: Reality is, after all, too big for our frail understanding to fully comprehend. Nevertheless, we have to build our life on the theory which contains the maximum truth. We cannot sit still because we cannot, or do not, know the Absolute Truth.

As We May Think (1945)
Context: If scientific reasoning were limited to the logical processes of arithmetic, we should not get far in our understanding of the physical world. One might as well attempt to grasp the game of poker entirely by the use of the mathematics of probability. The abacus, with its beads strung on parallel wires, led the Arabs to positional numeration and the concept of zero many centuries before the rest of the world; and it was a useful tool — so useful that it still exists.

Song lyrics, The Sensual World (1989)
Context: I turn to my computer like a friend.
I need deeper understanding.
Give me deeper understanding…

Context: The way of life that destroyed Hiroshima and Nagasaki and is reported to have roasted alive a million people in Tokyo overnight is international and dominates every nation of the world, but we live in the United States, so our struggle is here. With this way of life, death would be more appropriate. There could be no truce or quarter. The prejudices of patriotism, the pressures of our friends and fear of unpopularity and death should not hold us back any longer. It should be total war against the economic and political and social system which is dominant in this country. The American system has been destroying human life in peace and in war, at home and abroad for decades. Now it has produced the growing infamy of atom bombing. Besides these brutal facts, the tidbits of democracy mean nothing. Henceforth, no decent citizen owes one scrap of allegiance (if he ever did) to American law, American custom or American institutions.
