1903. As exhibited in a series of articles contributed to the Calcutta Review. Those interested in the general history of philosophy will find in this volume an account of a very early attempt on the part of thinkers of a rude age and race to form a cosmological theory. The Upanishads are so many songs before sunrise-spontaneous effusions of awakening reflection, half poetical, half metaphysical, that precede the conscious and methodical labor of the long succession of thinkers to construct a thoroughly intelligible conception of the sum of things. This introduction to the Upanishads will prove indispensable for readers who are interested in Indian matters.
