sentimental way, who crowd round a singer or pianist after his performance. It would certainly be easy for each of them to be jealous of the rest; but, in face of their numbers and the consequent impossibility of their reaching the aim of their love, they renounce it, and, instead of pulling out one another's hair, they act as a united group, do homage to the hero of the occasion with their common actions, and would probably be glad to have a share of his flowing locks. Originally rivals, they have succeeded in identifying themselves with one another by means of a similar love for the same object. When, as is usual, a situation in the field of the instincts is capable of various outcomes, we need not be surprised if the actual outcome is one which involves the possibility of a certain amount of satisfaction, while another, even though in itself more obvious, is passed over because the circumstances of life prevent its attaining this aim. What appears later on in society in the shape of _Gemeingeist_, _esprit de corps_, 'group spirit', etc., does not belie its derivation from what was originally envy. No one must want to put himself forward, every one must be the same and have the same. Social justice means that we deny ourselves many things so that others may have to do without them as well, or, what is the same thing, may not be able to ask for them.

It reveals itself unexpectedly in the syphilitic's dread of infecting other people, which psycho-analysis has taught us to understand. The dread exhibited by these poor wretches corresponds to their violent struggles against the unconscious wish to spread their infection on to other people; for why should they alone be infected and cut off from so much? why not other people as well? And the same germ is to be found in the pretty anecdote of the judgement of Solomon. If one woman's child is dead, the other shall not have a live one either. The bereaved woman is recognized by this wish.
