What is truth:
As a Professor Person, I value Truth a lot and I don’t like to see the concept perverted.
Of course the world isn’t flat, popular book title notwithstanding. The evidence is overwhelming that it is very nearly a sphere. But the Flat Earth Society claims it is and summarily rejects the evidence to the contrary. I could attach a url to their homepage, but they don’t deserve the visibility. Very simply: Their beliefs are wrong. I’m not making a moral judgment – they might be very fine people, perhaps even qualified to run for VP on the GOP ticket – and they are entitled to believe anything they want. But it is a fact that what they believe is not correct. They are wrong, mistaken, in error. Their beliefs do not correspond to the Truth. As a person, I grant each of them the right to believe any hare-brained absurdity. I don’t grant any of them the ability to make it true. I can’t grant that, since I don’t control the Truth. Truth is.
Truth is.
Truth is that the Theory of Evolution explains how biology works and is brilliant Science. It predicts the results of experiments and we use it all the time to make sound medical and financial decisions (like which hybrids to plant).
Truth is that the universe is about fifteen billion years olde (Very Olde!) and expanding and cooling. This is based on Einstein’s Theory of Relativity, which has been validated by experiment and observation thousands of times, and the Red Shift and detection of the remnants of the Big Bang. And by the way “Theory” in these sentences does not mean “guess.”
A smart guy named Alfred Tarski defined Truth in 1933 in Polish. The essence of that one hundred plus pages of carefully reasoned logic is that a statement like “Snow is white” is Capital-T True if and only if real-live snow is real-live white.
The point: You don’t get to choose what is True. The universe determines Truth.
So you can believe the Moon is made of green cheese, humans and apes were created as is 6000 years ago, the world is flat and sits on the back of a big damned elephant, or π = 3. Believin’ don’t make it so.
