“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.”
