When do we fight, and when do we run away? In the past, to fight would have been the best survival strategy ,so to be without fear would have been beneficial. The problem is when fear is lost, then anxiety (perception of fear) is lost, and without anxiety there can be no conscience, so we get this collateral damage of tribal warfare and criminality, It does seem that feeling fear and anxiety is essential for the survival of our species because it gives us a conscience.</p>TjgreenWed, 10 Sep 2008 08:29:55 -0000
