Semantic Reasoning: A Scientific Commentary on Nyaya Sutras

Nyāya is one of the Six Systems of Vedic philosophy, and Nyāya Sūtra is the oldest and most authoritative text on this philosophy. This book translates and comments on this ancient text. Nyāya presents an alternative system of logic and reasoning in which reality exists as a potential, and it manifests an answer based on a question. This question is called "e;absence"e; and the answer is called "e;presence"e;. We are all combinations of some presence and absence—i.e., some answers and questions. Our interactions with the world are thus described just like conversations between two people. Happiness is created when the answers match the questions and the questions match the answers. Unhappiness is produced when the questions and answers are mismatched. This match or mismatch is based on the meanings in the question and answer; hence all reality must be studied as a text. It is just like sentences comprised of words and letters, not physical matter, force, or deterministic laws. The sequence of questions and answers is not deterministic because each question can be answered in different ways, and each answer can lead to different questions. Therefore, this scheme of logic is not contrary to free will. Free will in this description of logic is the ability to ask a different question based on a given answer, or the ability to provide a different answer to a given question. By exercising this choice of changing our questions and answers, the soul can alter its trajectory in the world.
