the earliest form of organic life began with mere naked specks of protoplasm, non-nucleated, or with no easily recognisable nucleus, which gave rise to the so-called unicellular creatures. These were followed by those whose bodies consisted of more cells, the multicellular. In this manner the manifestation of organic life became more and more complex, till it reached its culminating point in man. The evolution of sychic functions has also been traced out very elaborately. It has been surmised that the nervous system developed side by side with the physical body, so that when the organism became multicellular, the nervous system spread out like a network of nerve wires and centres. In man this has reached a very extraordinary state of complexity, which accounts for his wonderful mental powers, though it is impossible to avoid the conclusion that the lower animals also possess the power of thinking and reasoning in proportion to the development of the brain and the nervous system. Such, briefly, is the explanation which modern science gives of our Universe.
At this stage it is worth while to enquire into the nature of force itself. The question is, what is force ? There is a great diversity of opinion on this point, and men of learning are divided amongst themselves, some thinking that it must be of the nature of matter, others denying it. But, since it is impossible to look upon anything as being altogether devoid of substantiveness, force must be held to be bound up in some kind of substance. Thus understood, force becomes an aspect or function of substance ; for there can be no such thing as an immaterial entity. According to Prof. Haeckel,
