functioning of the different organs and finally seriously injuring them. To support this second claim I bring forward the following arguments: (a) Till now little or no attention on a practical psycho-physical basis has been given to the vital and harmful influence of this faulty direction (of subconscious origin) and of the erroneous preconceived ideas and faulty posture associated therewith. Under such influences the subject can hardly fail to cultivate a wrong mental attitude towards life in general and towards the art of living (evolving satisfactorily), especially in regard to the primary causation of the defects which may be present or which may develop eventually, but also in regard to the essential laws connected with the eradication of these defects. (b) Owing to the lack of distinction between reasoned (conscious) and unreasoned (subconscious or partly-conscious) actions, the subject suffers from various forms of mental and physical delusions, notably with regard to the physical acts he performs. Incidentally it should be pointed out that if this is true of the ordinary acts of everyday life how much more so of those physical acts which may be necessary to meet the demands of some new environment! As a striking instance of delusion in physical acts let us take the case of a man _who believes himself to be merely overcoming what he regards as essential inertia, when he is really fighting the resistance of undue antagonistic muscular action exerted by himself_, a resistance of which he is not consciously aware. In all such cases there is a constant conflict between two great forces, the one (subconscious) destined to exercise supreme directive powers during the early stages of human evolution, the other (conscious) to supersede this limited direction and finally to prove the reliable guide through the higher and highest stages of the great evolutionary scheme which leads to the full enjoyment of his potentialities. It must be remembered that the former became firmly established during centuries of subconscious direction, holding undisputed sway until the first glimmering of reasoned conscious guidance came in its crudest form to disturb its power, a power which it is destined one day to overthrow. In the present stage of our mental and physical progress the conflict continues with gradually increasing energy, and while the conflict is being waged the subject is influenced first in one direction by the dictates of his subconsciousness (called by some “instinct,” by others “intuition”), and then in another by his awakened conscious powers which he is gradually but slowly developing. Of the real significance of this conflict he has, unfortunately, no true realisation. At the same time he undoubtedly feels the force of these two influences as conflicting energies, but only in a dim, mysterious way. He is swayed first by one force and then by the other as happens when we hear a man or woman say,
