I think the average man is very apt to forget that he cannot assume a position of stable equilibrium and a position which ensures a perfect mobility, unless his feet are so placed as to furnish at once a stable pose and a ready pivot and fulcrum. The most perfect base is obtained by setting the feet at an angle of about forty-five degrees to one another. In all other erect positions (the defects becoming exaggerated as this angle is decreased), it will be found that there is a tendency to hollow and shorten the back and to protrude the stomach, and if any effort is made to avoid these serious faults in posture, such effort will only result—unless the feet are moved to the correct position—in a stiffened, uneasy, and unstable attitude. It is not possible, however, to set out in written language the correct pose of the feet and legs in the ideal standing position, and I therefore subjoin four photographs which have been specially taken for this purpose (first published on 22nd October, 1910), and which show quite clearly not only the correct position of the feet, the fundamental problem, but also how the whole body of the person is thereby thrown into gear. But when this ideal position is realised, the task of obtaining it by each individual has still to be undertaken. With reference to this task, I cannot do better than quote my pamphlet of July, 1908, entitled _Why “Deep Breathing” and Physical Culture Exercises Do More Harm than Good_, from which it will be clearly seen that the ideal position varies slightly according to the idiosyncrasies of the person concerned. The passage in question is as follows: “In the first place, to allow a pupil to assume, of himself, a certain standing position, means that his own perceptions and sensations are given the sole onus of bringing about the co-ordination upon which such standing position depends, an onus which they are quite unable to bear. “The perceptions and sensations of all who need respiratory and physical re-education are absolutely unreliable. It is the teacher who should have the responsibility of certain detailed orders, the literal carrying out of which will ensure for the pupil _what is then the correct standing position for him_. I emphasise this last, because no one stereotyped position can be correct for each and every pupil. When the person so employs the different parts of his body that one can speak of his ‘harmful position in standing or walking,’ it is only by causing the physical machinery gradually to resume correct and harmonious working, thus changing the position from time to time, that serious harm can be averted and satisfactory results secured. I may point out, moreover, that in trying to assume the ‘proper standing position’ at the outset, the pupil unavoidably puts severe strain upon the throat, thereby paving the way for throat, ear, and eye disorders.”
