This idea of the eternal reality of the body springs directly from those ideas of truth, beauty and goodness which are pre-existent in the universe and therefore springs directly from that emotion of love which is the synthesis of these.
The forms and shapes of stars and plants and rivers and hills are all realized and consummated in the form and shape of the human body. The magic of the elements, the mystery of earth and air and water and fire, are incarnated in this miracle of flesh and blood. In the countenance of a human child, in the countenance of a man or a woman, the whole unfathomable drama of life is expressed. The most evil of the children of men, asleep or dead, has in his face something more tragic and more beautiful than all the waters and all the land.
Not to "love" flesh and blood, not to will the eternal existence of flesh and blood, is not to know "love" at all. To loathe flesh and blood, to will the annihilation of flesh and blood, is to be a victim of that original "motiveless malignity" which opposes itself to the creative force.
This insistence upon "the eternal idea of the body" does not necessarily limit "the idea of the body" to the idea of the human body; but practically it does so. And it practically does so because the human body evidently incarnates the beauty and the nobility of all other forms and shapes and appearances which make up our existing universe.
There may be other and different bodies in the unfathomable spaces of the world; but for those among us who are content to deal with the actual experiences which we have, the human body, summing up the magical qualities of all other terrestrial forms and shapes, must, as far as we are concerned, remain our permanent standard of truth and beauty.
The substitution in art, in philosophy, and in religion, of other symbols, for this natural and eternal symbol of the human body is always a sign of a weakening of the creative impulse. It is a sign of a relative disintegration of the power of "love" and a relative concentration of the power of "malice." Thus when, by an abuse of the metaphysical reason, "thought-in-the-abstract" assumes the rights of a personality the principle of love is outraged, because the eternal idea of the body is denied.
