The search for the self-identity is forever the ultimate goal of an alive human being. I indeed discussed about some related issues with my friend on similar topics, e.g., if being gay is an illness or not, if color blindness is a deficiency or are we ‘normal people’ seeing ‘too much’ than we ought to see. Actually it is a quite pleasant and interesting topic when discussing some unique features not that serious in nowadays and especially when they are not occurring to you. I once wondered that if color blindness is due to the deficiency of the eyes or the deficiency of the brain and it turned out that science proves the correctness of the former explanation. However, as we know color blindness is a kind of heritable gene differences from the rest of us, how we argue a ‘correct sample’ out of all different kinds of gene mutations. Correctness is hard to define, yet we are trying to form a standardized reference out of the the great majority. We say that it is the ‘right’ one when most people possess this feature - an obvious double standard when saying that truth always rests in the hands of a few people.
