The Kesamutti Sutta states:
Do not go upon what has been acquired by repeated hearing,
nor upon tradition,
nor upon rumor,
nor upon what is in a scripture
nor upon surmise,
nor upon an axiom,
nor upon specious reasoning,
nor upon a bias towards a notion that has been pondered over,
nor upon another's seeming ability,
nor upon the consideration 'The monk is our teacher'
Kalamas, when you yourselves know 'These things are good; these things are not blameable; these things are praised by the wise; undertaken and observed, these things lead to benefit and happiness,' enter on and abide in them.
Thus, the Buddha named ten specific sources whose knowledge should not be immediately viewed as truthful without further investigation to avoid fallacies:
Oral history
Tradition
News sources
Scriptures or other official texts
Suppositional reasoning
Philosophical dogmatism
Common sense
One's own opinions
Experts
Authorities or one's own teacher
Instead, the Buddha says, only when one personally knows that a certain teaching is skillful, blameless, praiseworthy, and conducive to happiness, and that it is praised by the wise, should one then accept it as true and practice it.
