You better have religion.”

The important inventions which have been brought about in every realm of science from false hypotheses number in the hundreds, indeed in the thousands.”
—Stefan Zweig (18811942)
“The three main medieval points of view regarding universals are designated by historians as realism, conceptualism, and nominalism. Essentially these same three doctrines reappear in twentieth-century surveys of the philosophy of mathematics under the new names logicism, intuitionism, and formalism.”
