In Iran, the government and the people don't pay much attention to humanities. There is a sense among most parents that only Engineering and Medicine are important. That view is much worse when it comes to philosophy. My friend thinks it's a non-practical, useless, confusing object. But I have discussed with him about Epistemology and talking about knowing that the truth is related to perspective and that there is no real truth. Then he said "Ok. I understood we can't know truth about anything --then what?"

I've told him that if you know all of the sciences but you can't think critically you have missed a big thing. but he just said "Ok" in an ignoring manner.
