The OP goes into some detail on the essentialness of honesty and integrity when it comes to inquiry. Without both, your pursuit of deep understanding will short-circuit. The best way I know to overlook truth is to willfully presume you know something, especially something unknowable. And that's faith. To exercise faith, you must stop questioning, shut your eyes, and jump into the abyss. You stop thinking. If some sort of understanding arises from faith, it most certainly is not the fruit of intellectual pursuit.
