 The fact that humans reason is no guarantee that those who do reflect on which reasoning is good and which is bad. Clearly, the activity of reasoning, on the one hand, and the activity of reflecting on which reasoning is good and which is not, on the other, are distinct, though naturally they are intimately related. The exposition here, while reporting primarily on what is explicit, will also report on what is implicit. In looking at the origins of reasoning in India, it is natural to begin with the practices in which reasoning played a role and which, as a result, were likely candidates for reflection. The obvious starting points for such practices are all forms of rational inquiry.
