Introduction

The book explores the worlds of actual consciousness and of the purely logical naturally involved finding the lines separating psychology and phenomenology and that separating phenomenology and the objective sciences. Edmund Husserl came to divide the world of actual consciousness into the realms of the psychological and the phenomenological. He presents pure logic as the science of the form concept to which the objective content of all logical, all scientific thinking in general is subject. The three levels of pure logic are described into Logic and Theory of Knowledge 1906/07 and of Formal and Transcendental Logic is devoted to them. Husserl saw the general theory of manifolds, or science of theory forms, as a field of free, creative investigation made possible once it is discovered that deductions, series of deductions, continue be meaningful and to remain valid when one assigns another meaning to the symbols.
