Professor Foerster, whose books on the subject of the {198} training of youth and especially on sex matters in youth attracted so much attention shortly before the war, faced frankly this problem of the necessity for the practice of mortification, or as he did not hesitate to call it, genuine asceticism, the exercise of the virtues of self-control and self-denial as the most important factor for the protection of youth. He said: "All solutions of the sex problem which tend to emancipate sex feeling from the control of moral and spiritual law (instead of making it the chief aim to place the spirit in a position of mastery over the sex nature) are essentially hostile, not only to our whole social evolution and to the development of individual character, but to actual physical health in the sphere of sex. To secure the mastery of man's higher self over the whole world of animal desire is a task, however, which demands a more systematic development of will-power and the cultivation of a deeper faith in the spiritual destiny of humanity than are to be found in the superficial intellectualistic civilization of to-day. To achieve such a result it will be necessary not only to have recourse to new methods and new ideals, but to make sure that we do not allow what is valuable and in any way worthy of imitation, in the old, to be forgotten. The ascetic principle in particular is to-day in danger of being undervalued." The cult of the body which has become so much the occupation of the present generation, which refuses to make the necessary effort of mind to secure intellectual pleasures, has always been the special deprecation of the Church. A great many of the words in the language show the effect of that religious attitude very clearly. Sensuousness, while its original meaning is only anything connected with the senses, has come to mean the quality {199} of being particularly alive to the pleasure that is received through the senses and therefore by implication, at least, not particularly intellectual. The _Edinburgh Quarterly_ reviewer long ago, in the famous article which Byron suggested as having snuffed out the "fiery particle" of Keats' soul, hurt him most by suggesting his lack of intellectuality and declaring that he was "too soft and sensuous by nature to be exhilarated by the conflict of modern opinions", hence "he found an opiate for his despondency in the old tales of Greek mythology." Sensuality even more than sensuousness has come to mean under the sway of the senses and the bodily desires rather than of the mind. Pope spoke of men "sensualized by pleasure" like those who were "changed into brutes by Circe."
