The following is the opening argument I made in a debate years ago over whether absolute truths exist with a friend . Please tell me if you agree or disagree.
To say that absolute truth does not exist, is to imply that in some sense, that all knowledge is subjective or relative, and that no piece of information could be independently and objectively verifiable. In abstract concepts like numbers and mathematics we clearly find universal constants that have no deviation. Einstein’s beautiful equation that E=mc2, has been proven repetitively by the most modern scientific instruments of today. And even if it were to be disproven, all that would simply mean is that there is another truth out there, which is currently beyond our scope of knowledge.
Surely of course there are ideas that have their truth lay in opinion. For example, if one were to ask “Is Brittany Spears talented?” this of course would be a matter of individual tastes. An absolute truth cannot lay in opinion or preference, or even consensus, it must be objective. It must be true and verifiable regardless of whether anyone agrees with it or not. That is one of the beauties of science: it’s true whether you believe in it or not. The close-minded religious fundamentalists who think the Earth is just 6,000 years old and that dinosaurs coexisted with man have no argument in the face of contradictory evidence. Their “reality” is forever intellectually silenced, and the evidence in this case is the objective truth.
Now suppose that you believe that reality is just a projection of one’s thoughts and ideas. So in a sense, if in my reality the inverse-square law doesn’t apply, then it is not an absolute truth. Let’s say I regard it just as another person’s mathematical theory, unsupported by evidence, easily falsifiable, and made up by some geek with too much time on his hands. Or let’s say that in my reality, the Aztecs defeated the Spanish conquistadors and their empire is still prospering to this day, unabated. One can go on believing these things all they want, and for as long as they want, but wouldn’t they be a little detached from reality, much as the wildly imaginative Don Quixote? This also reminds me of my gullible father falling for The Secret and thinking that his mere thoughts were going to change the nature of the whole Cosmos.
Absolute truth is also married to absolute reality; that is to say, a reality that is objective to anyone’s subjective interpretation of it. September 11th, was a joyous day for some, but a devastating day for others. Regardless what how one thinks about those events that transpired that day, the objective truth is that they happened. Now I don't deny that we have evidence that our consciousness can affect quantum particles and in a sense affect reality, but even if aspects of reality are subjectively true, it would still be absolutely true that aspects of reality are subjectively true.
Logically speaking, saying that absolute truth, or any truth for that matter, doesn’t exist, is contradictory. For example, if you assert absolute truth does not exist, then if you’re right, wouldn’t your statement then be an absolute truth? In other words, wouldn’t it be absolutely true, that absolute truth doesn’t exist? This assertion would then be a logical contradiction, because such a statement would be completely self defeating. You cannot say that truth doesn’t exist, because in order for this to be right, it would have to be true. The only logical option is that truth does exist, and if truth does exist, absolute truth follows thereafter.
