“The spiritualist or the idealist believes in a spiritual essence of force; spiritual, that is to say phantomatic, inexplicable. The man of materialist science is an unbeliever. Nowhere does a scientific justification exist either for belief or unbelief. Materialism has the advantage that it is not seeking the transcendental, the essence, the cause, the force behind phenomena nor that beyond matter. But when he misconstrues the distinction between force and matter, when he denies the existence of the whole problem, he merely slips around behind idealism. The materialist asserts the real indivisibility of matter and force and to explain their seperation, gives value solely to "an exterior reason, born of the need for systemisation of our consciousness.”
