Context-dropping is one of the chief psychological tools of evasion. In regard to one’s desires, there are two major ways of context-dropping: the issues of range and of means.
A rational man sees his interests in terms of a lifetime and selects his goals accordingly. This does not mean that he has to be omniscient, infallible or clairvoyant. It means that he does not live his life short-range and does not drift like a bum pushed by the spur of the moment. It means that he does not regard any moment as cut off from the context of the rest of his life, and that he allows no conflicts or contradictions between his short-range and long-range interests. He does not become his own destroyer by pursuing a desire today which wipes out all his values tomorrow.
A rational man does not indulge in wistful longings for ends divorced from means. He does not hold a desire without knowing (or learning) and considering the means by which it is to be achieved.
Whenever you tear an idea from its context and treat it as though it were a self-sufficient, independent item, you invalidate the thought process involved. If you omit the context, or even a crucial aspect of it, then no matter what you say it will not be valid . . . .
A context-dropper forgets or evades any wider context. He stares at only one element, and he thinks, “I can change just this one point, and everything else will remain the same.” In fact, everything is interconnected. That one element involves a whole context, and to assess a change in one element, you must see what it means in the whole context.
