them. And so one may almost take as another mark of the genius that the phrase "this is no longer true" has no meaning for him. There is nothing that is no longer true for him, probably just because he has a clearer idea than other men of the changes that come with time.
The following appears to be one of the best means for the objective examination of the endowment of a man: If after a long separation from him we resume the new intercourse with the circumstances of the last, then we shall find that the highly endowed man has forgotten nothing, that he vividly and completely takes up the subject from where it was left off with the fullest recollection of the details. How much ordinary men forget of their lives any one can prove to his astonishment and horror. It may happen that we have been for hours importantly engaged with a man a few weeks before, and we may find that he has forgotten all about it. It is true that if one recalls all the circumstances to his mind, he begins to remember, and, finally, with sufficient help, may remember almost completely. Such experience has made me think that there may be an empirical proof of the hypothesis that no absolute forgetting ever occurs; that if the right method with the individual be chosen recollection may always be induced.
It follows also that from one's own experience, from what one has thought or said, heard or read, felt or done, one can give the smallest possible to another, that the other does not already know. Consideration of the amount that a man can take in from another would seem to serve as a sort of objective measure of his genius, a measure that does not have to wait for an estimation of his actual creative efforts. I am not going to discuss the extent to which this theory opposes current views on education, but I recommend parents and teachers to pay attention to it. The extent to which a man can detect differences and resemblances must depend on his memories. This faculty will be best developed in those whose past permeates their present, all the moments of the life of whom are amalga-
