i think what you guys mean by an absolute truth is actually called an analytical truth... which does exist. an analytical truth is a proposition that is self-evidently true, such as: no bachelors are married, all squares have 4 sides, or as arbiter said, 1 + 1 = 2. in contrast to analytical truths (or analytical falsities) there are synthetic truths (and falsities) which require us to go out into the world and see if they are true, such as: i am over 6 feet tall. however, truth is an objective property, independant of people's thoughts or beliefs. a proposition can either be true, or false, never both.
