Two forces are succesfully influencing the education of a cultivated man: art and science. Both are united in the book.
To speak the truth is the most difficult of all arts, for in its "pure" form, not connected with the interests of individuals, groups, classes, or nations, truth is almost completely unsuitable for use by the Philistine and is unacceptable to him.
The good qualities in our soul are most successfully and forcefully awakened by the power of art. Just as science is the intellect of the world, art is its soul.
