Kesamutti Sutta

The Kesamutti Sutta, popularly known in the West as the Kālāma Sutta, is a discourse of the Buddha contained in the Aṅguttara Nikaya (3.65) of the Tipiṭaka. It is often cited by those of the Theravada and Mahayana traditions alike as the Buddha's "charter of free inquiry."

The Kesamutti Sutta is often incorrectly used for advocating prudence by the use of sound logical reasoning arguments for inquiries in the practice that relates to the discipline of seeking truth, wisdom and knowledge whether it is religious or not. However, a plain reading of the text clearly states that one should not determine the validity of tradition based "by logical conjecture, by inference, by analogies, by agreement through pondering views, by probability, or by the thought, 'This contemplative is our teacher.'" While nothing in the text limits one from employing their own reasoning, the Buddha instructs not to make a decision based alone on it. Instead, the Buddha teaches that one can determine the validity of a tradition if "These qualities are skillful; these qualities are blameless; these qualities are praised by the wise; these qualities, when adopted & carried out, lead to welfare & to happiness' — then you should enter & remain in them." The misunderstanding of this sutta has become popular in part by reliance on a fake quote attributed to the Buddha and this sutta that includes "when you find that anything agrees with reason and is conducive to the good and benefit of one and all, then accept it and live up to it," which is in part the opposite of what the sutta actually states.
