I don't claim to know enough Heidegger (does anyone?), but I think that Heidegger was making the case that we can never know the whole truth. Our brains can not hold all the information equally at the same moment in time to comprehend the "truth" of anything. The very process of turning our attention and focusing excludes some aspect (I could use the word characteristic or quality or variable here in the place of aspect) of the truth or falsely emphasizes one aspect of a thing (to include anything one is examining - a mathematical formula, a table, an idea, etc...)over other aspects.Robert Tulip wrote: Heidegger was widely interpreted as saying that truth is subjective, but his point was rather that truth should be integrated with life, and cannot be a pure abstract idea. Such an integrated vision of truth still has room for objective certainty. Burton seems to want a similar integration of truth and life, except that his radical skepticism about any knowledge claims seems to deny any human access to truth of the type claimed by Einstein.
In away I think Burton is getting at a similar idea. Truth, knowledge, knowing is a slippery fish and maybe the most important first step in getting a hold of it is to understand the limitations of a human brain in knowing a truth. I think even Einstein would agree.
You know, the old adage: The more I know the more I realize I don't know.
