... the only way to get an absolute truth about something is that u created it, and you will just have the absolute truth of its function nothing else... so if theres an absolute truth about nature, any human can get it, just because we are humans, we think subjetively, and we r not taht smart to discover all the things that nature could hide.
finally im with opti... as i said each one has his own absolute truths but as a group the truth is relative >.<
