Of course there is absolute truth. If truth were not absolute then it would make no difference what we do. Everyone has found that at about the age of 2 that what you do make a difference in results. If you have been paying attention all you life you should know by now that going against absolute truth has bad results. I think the number of repeated bad choices they make never realizing that they are making choices against basic truth may judge the intelligence of a person.
yes, we are expressions of absolute truth, but we are under illusion if we think we are representing it absolutely objectively. ie. mathematics are elitist to the nonmathematician. philosophy is elitist to the non philosopher. etc...
yet all the people (and animals and plants etc.) in the world who have there own versions of truth, still exist, and mathematicians still exist for all the others.
the complexity of ones truths reflects the individual constructor of the truth, and is also linked directly to their intentions.
for example, fish F may have the truth: subject X provides quality Y for my own survival. (one obviously cannot assume to understand another, unless one IS the other, but this is just an example)
but fish P may have the truth: subject X provides quality Z for my offsprings survival.
now, when fish F and P both desire subject X for say quality T (maybe to restore a dwelling) quality T would be considered an objective truth, no?
ohhh... maybe not but it makes you think though doesn't it?
substitute the fish F for one culture of the human race, and fish P for another and what do you get? maybe a surprisingly accurate representation of Reality.
