My own paraphrasing: Essentially born out of ignorance, how would one's own reason and common sense, also derived from ignorance, help you ascertain the truth?

Here's the version I found & use..

• Do not go by revelation;
• Do not go by tradition;
• Do not go by hearsay;
• Do not go on the authority of sacred texts;
• Do not go on the grounds of pure logic;
• Do not go by a view that seems rational;
• Do not go by reflecting on mere appearances;
• Do not go along with a considered view because you agree with it;
• Do not go along on the grounds that the person is competent;
• Do not go along because "the recluse is our teacher."
• Kalamas, when you yourselves know: These things are unwholesome, these things are blameworthy; these things are censured by the wise; and when undertaken and observed, these things lead to harm and ill, abandon them...
• Kalamas, when you know for yourselves: These are wholesome; these things are not blameworthy; these things are praised by the wise; undertaken and observed, these things lead to benefit and happiness, having undertaken them, abide in them.

Kalama Sutta - Angutarra Nikaya 3.65

You can note that Gautama's telling people to trust what they have experience-induced-understanding of, not what mere-cognition or mere-idea or mere-consensus, etc, push.

In AwakeSoulism/Buddhism there is a concept of valid knowledge which helps understand what Gautama's trying to communicate:

WHEN one knows something sooo profoundly, that even being killed, again & again & again through reincarnation cannot blot-out, displace, or hide that knowing, THAT is what valid knowing means: it is simply "meaning one can take with one", but taken to its ultimate-limit, so one's continuum/soul is doing the knowing, not merely one's SurfaceMind, or one's LifeMind ( unconscious-mind, in us, or dreaming-mind ).
