Blow away (Freud)

The deficiencies in our description would probably vanish if we were already in a position to replace the psychological terms with physiological or chemical ones.... We may expect [physiology and chemistry] to give the most surprising information and we cannot guess what answers it will return in a few dozen years of questions we have put to it. They may be of a kind that will blow away the whole of our artificial structure of hypothesis.
