Swami Vivekananda confronted the problem on the other front too. He was critical of the extravagant claims put forth by science on man's allegiance. If religion has its superstitions. As soon as a great scientist's name like Darwin or Huxley is quoted, people accept the statement blindly. He critically examined the mechanical and evolutionary theories and found them inadequate and unsatisfactory. He was of the firm opinion that no system or philosophy based purely on materialistic or utilitarian ideas can satisfy or explain the whole of human existence or can provide answer to all the problems of human existence. The Swami shows that the theory of evolution was incomplete, because the very evolution presupposes an involution. Something cannot come out of nothing. We can get from a machine only that much amount of energy which we put into it. If a man is an evolution of mollusc, the perfect man, the Buddha man, the Christ man must be involved in the mollusc. Secondly our struggle for higher life shows that we have been degraded from higher states. Another point of controversy which Vivekananda took up, was whether the aggregate of materials we call body is the cause of the manifestation of force we call thought? Taking the position that thought is simply the outcome of adjustment of the parts of the machine called body leaves the question unanswered. What makes the body? What force combines the molecules into the body form? To say that the force called soul is the outcome of body is to put the cart before the horse. The cause is always finer than the effect. That theory must be accepted which explains most facts, if not all, without contradicting most of the theories already existing. It is more logical to say that the force which takes up the matter and forms the body is the same which manifests through the body.

Neither can force evolve out of matter. Rather it is possible to demonstrate that what we call matter does not exist at all. It is only a certain state of force. Solidity, hardness, or any other state of matter can be proved to be the result of motion. Increased vortex motion imparted to fluids gives them the force of solids. A mass of air in vortex motion as in a tornado becomes solid-like and by its impact breaks or cuts through solids. A spider's web if it could be moved at almost infinite velocity, could be as strong as an iron chain and would cut through an oak tree.
