What Mathematical Certainty?
Fifth in a series on the search for meaning in a world that doesn't want to bother with it.

I found Einstein's comment among the exercises in With Good Reason, a textbook on informal fallacies by S. Morris Engel. In the exercise, Engel directed the reader to analyze the language of the statement. Two questions came to my mind. Was Einstein kidding? Was he making a defensible assertion?
Without the context of the statement, I do not know. Even with the context, I probably wouldn't know, seeing it was Einstein who said it - but I would tend to believe it because it was Einstein. If I believe him when he says that energy equals mass multiplied by the square of the speed of light, though I have no idea what that means or why it should be so, I can easily believe him when he says that mathematics has an uncertain reference to reality.
My belief proves nothing. Neither would the opposite conclusion that Einstein was talking nonsense. We know from other instances that he was not above paradox — a fancy way to kid around — as when he said that God does not play dice with the universe. While it is unlikely he had the biblical God in mind, we are not sure what or who else he had in mind. This lack of definition doesn't keep it from being one of his more popular quotations. We assume he meant something, even if we don't get it ourselves.
In the statement about mathematical certainty, however, he used "reality" as a standard of comparison. While we may or not know who God is, the concept of reality is available to all. We all live in the real world, right? Reality, to be real, only has to be. It doesn't owe anything to anybody. Mathematical descriptions apply to realities, but mathematical certainties apply only to themselves. Whether he was kidding or not, Einstein still brought into question the phrase — to a mathematical certainty — as it applies to the world beyond mathematics.
Mathematics is one of many ways we have to describe reality, not to explain it. Description is not explanation. "Two plus two" is a description. So is "Energy equals mass multiplied by the square of the speed of light."
Theist and secularist agree with each other that bigotry needs exposing and fact needs establishing, but the work of both proceeds on faith. Both the scientist and the metaphysician say at the beginning, "I will treat this statement as true and see if it leads anywhere but to a dead end." Neither should criticize the other for this commonsense approach to knowledge.
