Concerning culture as a process, one would say that it means learning a great many things and then forgetting them; and the forgetting is as necessary as the learning.

Diligent as one must be in learning, one must be as diligent in forgetting; otherwise the process is one of pedantry, not culture.

Learning has always been made much of, but forgetting has always been deprecated; therefore pedantry has pretty well established itself throughout the modern world at the expense of culture.

Considered now as a possession, one may define culture as the residuum of a large body of useless knowledge that has been well and truly forgotten.

Perhaps the prevalence of pedantry may be largely accounted for by the common error of thinking that, because useful knowledge should be remembered, any kind of knowledge that is at all worth learning should be remembered too.

The process of learning requires not only hearing and applying but also forgetting and then remembering again.
