Классификация наук в рамках философско-педагогической концепции С.И. Гессена

Hessen’s science classification is considered to be a tree of scientific methods which should contain brunches developing in three directions of basic science conceptions. The paper shows that each direction of science method has its own field of practical application, pedagogy being the field of practical application of philosophy. On the basis of the logical criterion three pedagogical rules are drawn out in the article.
