ABSTRACT
If a science is to come into existence at all, it will do so as more and more powerful concepts are introduced. Their formulation is often the work of empirical investigators, but it is philosophical, nonetheless, because it is concerned with meanings rather than facts, and the systematic construction of meanings is philosophy. Wherever a new way of thinking may originate, its effect is apt to be revolutionary because it transforms questions and criteria, and therewith the appearance and value of facts.
