"Indians conducted far more elaborate speculations than the Westerners of antiquity and the Middle Ages with respect to the theory of numbers, the analysis of psychological phenomena, and the study of linguistic structures. The Indians are highly rationalistic, insofar as their ideal is to recognize eternal laws concerning past, present, and future. The thought represented by Tertullian's aphorism, "credo quia absurdum," or "I believe because it is absurd," had no receptivity in India. The Indians are, at the same time, logical since they generally have a tendency to sublimate their thinking to the universal; they are at once logical and rationalistic. On the contrary, many religions of the West are irrational and illogical, and this is acknowledged by the Westerners themselves. For example, Schweitzer, a pious and most devoted Christian, says, "Compared to the logical religions of Asia, the gospel of Jesus is illogical.""
