Well, I know this will sound like a cop-out, but it depends on what you mean by truth. One person's truth is not necessarily the same as another person's. For example, to you, a hamburger might be the the yummiest thing in creation. Truth for you. But to a vegetarian...?
And knowledge or ignorance of WHAT? Would you want to know if you had inoperable cancer, or remain in ignorance? Some people will make one choice, some the other.
Ok. Nothing profound there. But the same principle, I think, applies in even profound matters. It is what works FOR YOU that matters. That is your truth.
