Henry Adams Quote

Like so many other great observers, Langley was not a mathematician, and like most physicists, he believed in physics. Rigidly denying himself the amusement of philosophy, which consists chiefly in suggesting unintelligible answers to insoluble problems, he still knew the problems, and liked to wander past them in a courteous temper, even bowing to them distantly as though recognising their existence though doubting their respectability.
