Again, let us take the science of Physiology. At present this is mainly carried on by means of Dissection or Vivisection. But both these methods are unsatisfactory. Dissection, because it amounts to studying the organisation of a living creature by the examination of its dead carcase; and Vivisection, because it is not only open to a similar objection, but because it necessarily violates the highest relation of man to the animal he is studying. There is, I believe, another method--a method which has been known in the East for centuries, though little regarded in the West--which may perhaps be called the method of Health. It consists in rendering the body, by proper habits of life, pure and healthy, till it becomes, as it were, transparent to the inner eye, and then projecting the consciousness _inward_ so as to become almost as sensible of the structure and function of the various internal organs, as it usually is of the outer surface of the body. Of course this is a process which cannot be effectuated at once, and which may need help and corroboration by external methods of study, but I believe it is one which will lead to considerable results. There is no doubt that many of the Yogis of India attain to great skill in it. Similarly, from what we have already said about Political Economy, it is obvious that satisfactory results in that science must depend immensely on the high degree of social instinct and feeling with which the student approaches it, and on the thoroughness of his acquaintance with the _actual life_ of a people; and that the development of these factors is fully as important a part of the science as that which consists in the logical ordering and arrangement of the material obtained.
