ABSTRACT
MASSON-OURSEL says that every intellectual culture possesses its own logic.1 An intellectual culture is expressed in the philosophy of the nation to which it belongs. Philosophy is the expression of systematized outlook. It is connected and consistent formulation of a people's beliefs, their achievements and aspirations. It is the best clue to the mind of the nation. It contains its soul, the guiding principle of the nation's reaction to the environment. In it can be found the pattern of thought and behaviour of the individual belonging to the nation. The pattern is the way in which the guiding principle leads and which it is. And it is the business of logic to study this pattern. In this study logic extricates the principle from the material in which it is entangled. Of course, the principle owes its form to the material. Yet logic studies the form and so far is admittedly an abstraction. That logic which studies the principle as it is exhibited in the various forms of thought is philosophical logic. And if every nation possesses its own outlook and therefore its own philosophy, then it must have its own logic, which is the study of the principle of the structure of its philosophy as a whole.
