This is a bad translation of the Kalama Sutta — so bad, in fact, that it contradicts the message of the sutta, which says that reason and common sense are not sufficient for ascertaining the truth.

Here’s the original version, from Access to Insight:

“Now, Kalamas, don’t go by reports, by legends, by traditions, by scripture, by logical conjecture, by inference, by analogies, by agreement through pondering views, by probability, or by the thought, ‘This contemplative is our teacher.’ When you know for yourselves that, ‘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.
