Ambedkar traces Buddha's rational approach, which he values so much, to Kapila, the founder of the Samkhya-Darshana, the 'viewpoint' focusing on cosmology: 'Among the ancient philosophers of India the most preeminent was Kapila (') The tenets of his philosophy were of a startling nature. Truth must be supported by proof. This is the first tenet of the Samkhya system. There is no truth without proof. For purposes of proving the truth Kapila allowed only two means of proof-1) perception, and 2) inference.
