“Fundamentalists need truth to be absolute. They are extremely uncomfortable with uncertainty or estimates of truth. They think truth is an object. Jesus said, “I am the truth.” But a person cannot be the truth. Truth is not a thing. Truth is simply a measure of how well a statement matches reality. The only thing that can be true or false is a statement, a proposition. Reality is not truth: reality is reality. If the sky is blue and I say, “The sky is blue,” then there is a strong correspondence between my statement and reality, so my statement would be true. If I say, “The sky is orange with black polka dots,” there is a very low correspondence, so my statement would be false. Of course, the sky is always changing color ( it is sometimes orange), and is dark during the night, so “the sky is blue” is a true statement that has to be qualified. It is not absolute.
In science and history, truth is always a matter of probability, not 100 percent certainty. Scientists talk about needing 95 percent confidence, or 98 percent confidence before claiming something is a fact, and even then it is qualified with a small amount of uncertainty.”
