rise to the pressing question, Whence comes this compulsion? We have already suggested above that the primitive sexuality encounters a resistance which leads to a side-tracking of the libido on to substitution actions (analogy, symbolism, etc.). It is unthinkable that it is a question of any outer opposition whatsoever, or of a real obstacle, since it occurs to no savage to catch his elusive quarry with ritual charms; but it is a question of an internal resistance; will opposes will; libido opposes libido, since a psychologic resistance as an energic phenomenon corresponds to a certain amount of libido. The psychologic compulsion for the transformation of the libido is based on an original division of the will. I will return to this primal splitting of the libido in another place. Here let us concern ourselves only with the problem of the transition of the libido. The transition takes place, as has been repeatedly suggested by means of shifting to an analogy. The libido is taken away from its proper place and transferred to another substratum.
The resistance against sexuality aims, therefore, at preventing the sexual act; it also seeks to crowd the libido away from the sexual function. We see, for example, in hysteria, how the specific repression blocks the real path of transference; therefore, the libido is obliged to take another path, and that an earlier one, namely, the incestuous road which ultimately leads to the parents. Let us speak, however, of the incest prohibition, which hindered the very first sexual transference. Then the situation changes in so far that no earlier way of transference is left, except that of the presexual stage of development,
