Waking up - mechanically, versus, on purpose

If there actually ARE truths, TRUTHS, correct facts about life, humanity, humans, the universe - thoughts and ideas that you can't immediately "put your finger on" right now (of that, you are pretty certain), but when you hear them, you recognize them AS truth - then, why do you think you need to HEAR them, in the first place, to acknowledge their existence?

If you hear a truth, or more correctly represented, a tru-ism - like, "honesty is the best policy" - then why does it need to be stated, when, at the time you do hear it, you instantly go, "yes, right, that's correct." That is, you already KNOW it, you already LIVE by it, it's already a part of your ordinary consciousness.

(Note, you will be very hard-pressed to find someone who goes: "wait, just a minute, I always thought dishonesty and thievery were the best policies - that's how I've been living - maybe I should rethink that.")
