This work is a systematic and critical study of two most important problems of philosophy — Reason and Intuition. The philosophical thought of the twentieth-century Indian thinkers articulates fresh ideas. Though they accept the metaphysical doctrines of Vedànta, one finds a good deal of originality in their world-views. The great thinkers are fully aware that unless they interpret and formulate the traditional truths in the modern framework of ideas, they would cease to inspire. There seems to be a distinct change in their views concerning man's existence in the world. The book embodies a fresh approach towards critical evaluation of some theories and gives valuable insights. It attempts to make relevant comparisons of the views of Indian thinkers with those of some of the eminent thinkers of the West. In the detailed study of Sri Aurobindo, K.C. Bhattacharyya and S. Radhakrishnan, the author shows, not only a profound grasp of the concepts of Reason and Intuition, but also the admirable understanding of other important metaphysical and religious problems. This book cannot miss the sight of students of philosophy, researchers and scholars.
