When philosophy has availed itself of the results of science, it has not been by
borrowing the abstract mathematical description of the pattern of events, but by borrowing
the then current pictorial description of this pattern; thus it has not appropriated certain
knowledge but conjectures. These conjectures were often good enough for the man-sized
world, but not, as we now know, for those ultimate processes of nature which control the
happenings of the man-sized world, and bring us nearest to the true nature of reality.5 Sir James Jeans, Physics and Philosophy
