Are facts and the truth really the same thing? Einstein was probably more concerned with his theory than the truth. But, he needed the truth, facts to prove that what he was thinking was correct. He depended on concrete to prove his jello wasn’t just jello. Without the concrete, well, you get the idea.
But, if the concrete he had wasn’t gonna make what he wanted… if it wasn’t going to set hard enough, he needed to find the concrete that would. So, just because something isn’t as it seems with what’s in front of you, it doesn’t mean that seeming can’t be believing. Keep working at it… keep researching… but also know when the point to stop is reached. If you waste your time looking for something to prove what seems, you’ve lost.
