Human Intercourse

A book on Human Intercourse might be written in a variety of ways, and amongst them might be an attempt to treat the subject in a scientific manner so as to elucidate those natural laws by which intercourse between human beings must be regulated. If we knew quite perfectly what those laws are we should enjoy the great convenience of being able to predict with certainty which men and women would be able to associate with pleasure, and which would be constrained or repressed in each other’s society. Human intercourse would then be as much a positive science as chemistry, in which the effects of bringing substances together can be foretold with the utmost accuracy. Some very distant approach to this scientific state may in certain instances actually be made. When we know the characters of two people with a certain degree of precision we may sometimes predict that they are sure to quarrel, and have the satisfaction of witnessing the explosion that our own acumen has foretold.
