A unitary method of thought is indispensable to the interpretation of European history. The pervasive dualisms which distort the thought of western man are an element in this general condition, which therefore must be diagnosed in a language which does not take these dualisms for granted. No interpretation of European man in traditional European terms can bring the truth to light, any more than the color-blind can know their deficiency. (p. 25)

Man set out on a two-thousand-year trial of a particular method of differentiation, adapting the structure of his mental processes, conscious and unconscious, to a certain general form. We need to consider only the most general characteristics of this form, and for the purpose of this analysis, there reduce to two. Thought may be either unitary or dualistic (since other pluralistic forms may be neglected), and it may be either process or static. These two pairs produce four combinations or types of thought: unitary-process, unitary-static, dualistic-process and dualistic-static. The first and the last are the most stable and common types; the unitary-static and dualistic-process forms are less frequent and may be regarded as anomalous forms appearing at times of transition.
