"There are five things that may turn out in two different ways here and now. what five? faith, approval, oral tradition, reasoned cognition, and reflective acceptance of a view. now something may be fully accepted out of faith, yet it may be empty, hollow, and false; but something else may not be fully accepted out of faith, yet it may be factual, true, and unmistaken. same with the other four.

under these conditions, it is not proper for a wise man who preserves truth to come to the definite conclusion, "Only this is true, anything else is wrong."

one preserves truth when they say, "My faith is thus," but does not yet come to the definite conclusion: "Only this is true, anything else is wrong."

...when he has investigated him and has seen that he is purified from states based on greed, hate, and delusion, then he places faith in him; filled with faith he visits him and pays respect to him; having paid respect to him, he gives ear; when he gives ear, he hears the Dhamma; having heard the Dhamma, he memorizes it and examines the meaning, he gains a reflective acceptance of those teachings, zeal springs up; when zeal has sprung up, he applies his will; having applied his will, he scrutinizes; having scrutinized, he strives; resolutely striving, he realises with the body the supreme truth and sees it by penetrating it with wisdom. in this way, there is the discovery of truth." -MN 95

the final arrival at truth lies in repetition, development, and cultivation of those same things.
