Knowledge is never complete, can never be complete. That is a fact, the scientists can explore not only the atom but also the universe, the stars, what is beyond the stars, but their knowledge is limited, they can never, never have complete knowledge of the universe, any more than a mathematician, or a biologist, or any kind of specialist's knowledge must invariably be limited, which means, listen carefully, that knowledge always goes with ignorance. You follow my point? I wonder if you do. As knowledge can never be complete, it must always have the shadow of ignorance with it. And out of this knowledge springs thought. So thought is always limited. Right? Please come with me, move.
