ceased to exist. Now that he is by himself in facing the danger, he may surely think it greater. The fact is, therefore, that panic dread presupposes a relaxation in the libidinal structure of the group and reacts to it in a justifiable manner, and the contrary view—that the libidinal ties of the group are destroyed owing to dread in the face of the danger—can be refuted.
The contention that dread in a group is increased to enormous proportions by means of induction (contagion) is not in the least contradicted by these remarks. McDougall's view meets the case entirely when the danger is a really great one and when the group has no strong emotional ties—conditions which are fulfilled, for instance, when a fire breaks out in a theatre or a place of amusement. But the really instructive case and the one which can be best employed for our purposes is that mentioned above, in which a body of troops breaks into a panic although the danger has not increased beyond a degree that is usual and has often been previously faced.
