Jeez, that was my essay subject for my philosophy exam for high school graduation : "Does the truth depend on us?" I concluded "yes". Got 10/20
What is commonly accepted as "the truth" depends on a lot of factors.
Fourthdan, sometimes the earth
is flat. When we want to build a house we'd better consider the Earth is locally flat.
Okay, this example is a bit provocative, but I want to point out that even in science, most "truths" depend very much on the hypotheses we choose to consider.
