19.  And when, as time went on, we acknowledged our mutual affection, and that philosophy Philosophy, here, a truly Christian life. was our aim, we were all in all to one another, housemates, messmates, intimates, with one object in life, or an affection for each other ever growing warmer and stronger.  Love for bodily attractions, since its objects are fleeting, is as fleeting as the flowers of spring.  For the flame cannot survive, when the fuel is exhausted, and departs along with that which kindles it, nor does desire abide, when its incentive wastes away.  But love which is godly and under restraint, since its object is stable, not only is more lasting, but, the fuller its vision of beauty grows, the more closely does it bind to itself and to one another the hearts of those whose love has one and the same object.  This is the law of our superhuman love.  I feel that I am being unduly borne away, and I know not how to enter upon this point, yet I cannot restrain myself from describing it.  For if I have omitted anything, it seems, immediately afterwards, of pressing importance, and of more consequence than what I had preferred to mention.  And if any one would carry me tyrannically forward, I become like the polyps, which when they are being dragged from their holes, cling with their suckers to the rocks, and cannot be detached, until the last of these has had exerted upon it its necessary share of force.  If then you give me leave, I have my request, if not I must take it from myself.
