Opinions and Perspectives are simply that. Not fact and not truth. Given this presumption, though, society's common thinking is that perception or perspective is truth. Is fact. Each and every one of our world's views' provides us with a frame of reference from which we develop these perceptions, these 'truths'. What we see, hear, smell, touch, taste and feel (don't forget the sixth sense) construct our own opinions and perceptions. They are our warm security blankets.
