Before marriage both sexes have two different states, one before there is any inclination towards marriage, and another after there is one. The changes of these two states, and the consequent forming of minds, follow one after the other, as these states continually develop. But there is no time to describe these changes here, since they are varied and differ from one individual to another.

The actual inclinations towards marriage are, before marriage, only ideas in the mind, but they become more and more perceptible as feelings in the body. But after marriage the state of these inclinations tends towards linking and also reproduction. It is obvious that these are as different from the earlier states as results are from intentions.
