In Synthesis of the Doctrine of Race Evola sets out his own racial doctrine on the premise of the tripartition of the human being into body, soul, spirit, on the basis of which the connections, correspondences and affinities between the different degrees of race (the corporeal sphere, the soul, and finally the spiritual sphere), are considered by analogy. In the first part, race is seen as a revolutionary idea. The three degrees of race are defined in the second part and elaborated upon in the third one. The fourth part begins with a clear definition of the term "Aryan" and ends with considerations of the racial issue from the point of view of law. Finally, the problem of the rectification of race is approached both on the basis of the principles of the doctrine of race and in a concrete manner.
