These Studies in Philosophy represents all the published and only a few unpublished writings of Krishna Chandra Bhattacharyya. These published writing date back 1908, but his characteristic philosophical position assumes definite shape in the writings during the year 1928-36. The publications of the period outnumber and far outweigh those that fall during the previous twenty years. Of the twenty-one tracts published first in two separate Volumes, which is this edition appear as bound together in one, fourteen belong to this period, the others covering the previous years. Prof. Bhattacharyya had a deep study of ancient Indian Philosophy, particularly of Advaita Vedanta, Sankhya, Yoga and Jain Philosophies. Vol. I. contains Prof. Bhattacharyya?s constructive interpretation of these systems. He was also well-versed in classical German Philosophy, particularly that of Kant. His vast and deep study provided the intellectual background in the light of which his profoundly original mind could go on with the work of construction. He constructed a new system of his own which however is not easy to comprehend. Vol. II contains all the basic writings in which Prof. Bhattacharyya?s philosophy has been formulated. In the Introduction to this Volume the Editor has usefully analysed the Author?s philosophical position in some details.
