The following is a contribution to the study of one general philosophical problem, that of unity, by pointing out—more doxographically than historically in the Western sense—what special viewpoints towards it are preferably taken by the Indian philosophers.

As I tried to prove in my Eigenart indischen Denkens and again in my Indian and Western Philosophy, a Study in Contrast, and as a student of mine emphasized in her thesis “The Concrete Expression of Abstract Ideas ”—-Indian philosophy as a whole takes its starting point from the Concrete, and even in its later apparently abstract deductions never loses sight of the Concrete (from Latin: con-crescere, the grown-together), as continually forced upon the Indian by the environing dynamic forces of a mainly tropical nature such as India's. The concept of unity, however, is a deduction or a postulate of human reasoning, never directly to be grasped from the Concrete, from the manifold phenomena of everyday life.
