I should say that the useful results of science had accumulated, but that there had been no accumulation of knowledge, strictly speaking, for posterity; for knowledge is to be acquired only by a corresponding experience. How can we know what we are told merely? Each man can interpret another's experience only by his own.

He too, however, occupies an equally narrow house at present.
