Context

“We must therefore assume that there exists in all men this power of knowing the Ideas in things, and consequently of transcending their personality for the moment, unless indeed there are some men who are capable of no æsthetic pleasure at all. The man of genius excels ordinary men only by possessing this kind of knowledge in a far higher degree and more continuously. Thus, while under its influence he retains the presence of mind which is necessary to enable him to repeat in a voluntary and intentional work what he has learned in this manner; and this repetition is the work of art.” source
