If we had followed materialism thus far with clear ideas, when we reached its highest point we would suddenly be seized with a fit of the inextinguishable laughter of the Olympians. As if waking from a dream, we would all at once become aware that its final result—knowledge—which it had reached so laboriously, was presupposed as the indispensable condition of its very starting-point. Mere matter; and when we imagined that we thought matter, we really thought only the subject that perceives matter: the eye that sees it, the hand that feels it, the understanding that knows it* Thus the tremendous petitio principii reveals itself 'unexpectedly ; for suddenly the last link is seen to be the startingpoint, the chain a circle; and the materialist is like Baron Münchhausen(Agrippa's trilemma), who, when swimming on horseback, drew the horse into the air with his legs, and himself by his queue. 1 . • • The crude materialism which even now, in the middle of the nineteenth century, 2 has been served up again under the ignorant delusion that it is original, . . . stupidly denies vital force, and first of all tries to explain the phenomena of life from physical and chemical forces, and those again from the mechanical effects of matter. 3 . . . But I will never believe that even the simplest chemical combination will ever admit of mechanical explanation; much less the properties of light, heat, and electricity. These will always require a dynamical explanation. 4
