seeing that the essential nature of Matter is quite alien to Mind? Or how in these circumstances should Mind act upon Matter, so as to translate its intentions into actions? The most absurd hypotheses have been propounded to answer these questions. However, up to the present the Monists are not in a much better position. They have tried three different ways of meeting the difficulty. Either they deny Mind and become Materialists; or they deny Matter in order to seek their salvation as Spiritualists; or they assert that, even in the simplest entities in the world, Mind and Matter are indissolubly bound together, so that there is no need to marvel at the appearance in man of these two modes of existence, seeing that they are never found apart. Materialism can never offer a satisfactory explanation of the world. For every attempt at an explanation must begin with the formation of thoughts about the phenomena of the world. Materialism, thus, begins with the thought of Matter or material processes. But, in doing so, it is ipso facto confronted by two different sets of facts, viz., the material world and the thoughts about it. The Materialist seeks to make these latter intelligible by regarding them as purely material processes. He believes that thinking takes place in the brain, much in the same way that digestion takes place in the animal organs. Just as he ascribes mechanical, chemical, and organic processes to Nature, so he credits her in certain circumstances with the capacity to think. He overlooks that, in doing so, he is merely shifting the problem from one place to another. Instead of to himself he ascribes the power of thought to Matter. And thus he is back again at his starting-point. How does Matter come to think of its own nature? Why is it not simply satisfied with itself and content to accept its own existence? The Materialist has turned his attention away from the definite subject, his own self, and occupies himself with an indefinite shadowy somewhat. And here the old problem meets him again. The materialistic theory cannot solve the problem; it can only shift it to another place.
