If common sense, and its associated logic, could answer the questions it poses, there would never have been a need for philosophy, or for much of science. The classic philosophical questions like “where did everything come from” cannot be answered by common sense, and therefore the answer, whatever it is, must be crazy, in common sense terms. To take an analogy, mathematicians could not answer every question in terms of integers, the counting numbers of common sense, so they had to invent fractions, and then real numbers, and eventually complex numbers, which include the notoriously crazy “imaginary” numbers. And then there is physics…the subject that gave us, thanks to Wolfgang Pauli, the phrase “not crazy enough to be true”.
