producing factors we are in no position to assign to each one the resultant part which really belongs to it (see p. 131). But the situation assumed in the principle of assistance can be varied, and for these new conditions we can formulate the following combination of questions which are worthy of a reply. What usually happens if in one constellation there is a meeting of pleasurable and painful conditions? Upon what depends the result and the previous intimations of the result? Tendency-wit particularly shows these possibilities. There is one feeling or impulse which strives to liberate pleasure from a certain source and under unrestricted conditions certainly would liberate it, but there is another impulse which works against this development of pleasure, that is, which inhibits or suppresses it. The suppressing stream, as the result shows, must be somewhat stronger than the one suppressed, which however is by no means destroyed.
The Fore-pleasure Principle
But now there appears another impulse which strives to set free pleasure by this identical process, even though from different sources it thus acts like the suppressed stream. What can be the result in such a case? An example can make this clearer than this schematization. There
