Okay, I never went to university , or had a college education, though I`m damn sure that "Truth" is "TRUTH" and it never changes
No truth does change. Phlogiston theory gave way to knowledge of oxygen. For most of us astrology gave way to astronomy. Alchemy gave way to chemistry. Natural philosophy gave us mathematics and geometry. In medicine antibiotics were a life-saving cure during World War 2 when they first started to be used. Now we know they destroy the friendly flora in the intestines and cause all sorts of problems if over used.
Truth does change because we are apes and it has taken us a heck of a long time to understand our planet and the cosmos and we are still learning. I heard a quiz-master on TV the other day say, 'what Pluto is no longer a planet, when did that happen?' When I was a child we had nine planets in the solar system, in fact in the known universe. Now we have eight but hundreds have been detected elsewhere in the galaxy.
I know you are talking about GB 'Truth' but you seemed to be so certain that truth never changes it bothered me.
