A clear-cut division must be made between general culture and the special branches. To-day the latter threaten more and more to devote themselves exclusively to the service of Mammon. To counterbalance this tendency, general culture should be preserved, at least in its ideal forms. The principle should be repeatedly emphasized, that industrial and technical progress, trade and commerce, can flourish only so long as a folk community exists whose general system of thought is inspired by ideals, since that is the preliminary condition for a flourishing development of the enterprises I have spoken of. That condition is not created by a spirit of materialist egotism but by a spirit of self-denial and the joy of giving one's self in the service of others.
