J. H. Levy

It is useless to consume our energies in mere verbal disputes. I must, however, caution students that definition is not a matter of indifference. Nine-​tenths of the embarrassments which surround most philosophical questions arise from the difficulty of getting a firm hold of them. When this is done, the solution is comparatively easy. Until it is done no solution can be rationally hoped for.
