  Obviously, it is not possible to explain to somebody outside of our thought collective the meanings of the concepts we use through verbal definitions, for we define words by other words which she does not understand to the same degree as she does not understand the defined word. It is not possible to define a word ostensively, for that person does not perceive in the world those objects which we perceive as belonging to the scope of the term defined. The only thing we can do is to teach her the basis of our thought style, like we teach our children and the young. The first step sometimes consists in creating a platform of partial understanding with a member of other collective for the price of impoverishing content and some deformations. But this is not argumentation but propaganda (1936, III).
