Q: 다음 글의 빈칸에 들어갈 말로 알맞은 것은? 

  Freud’s original idea of the unconscious was that it was a sort of receptacle or storehouse for repressed material, infantile wishes, and the like. But the unconscious is far more than that: it is (                                                          ). It represents the unconscious functioning of the psyche in general. It is psychic life before, during, and after consciousness. And inasmuch as the newborn child is presented with a ready-made, highly developed brain which owes its differentiation to the accretions of untold centuries of ancestral life, the unconscious psyche must consist of inherited instincts, functions, and forms that are peculiar to the ancestral psyche. This collective heritage is by no means made up of inherited ideas, but rather of the possibilities of such ideas-in other words, of a priori categories of possible functioning. Such an inheritance could be called instinct, using the word in its original sense. But it is not quite so simple. On the contrary, it is a most intricate web of what I have called archetypal conditions. This implies the probability that a man will behave much as his ancestors behaved, right back to Methuselah. Thus the unconscious is seen as the collective predisposition to extreme conservatism, a guarantee, almost, that nothing new will ever happen.
