Mmmm - I (if I am an individual) have never (as far as I know), wrestled in the same way as Jonathan Turner, with the meaning of my existence and the reality or otherwise of being a person on a trajectory from birth to death. At times it has crossed my mind that I might be a simulation in a cosmic computer game, or that I might wake up each day being a totally different person. But that is about as far as I have got. Nevertheless, Jonathan gives a good argument about how we can never know the truth about our own existence, about the existence of others or the existence and workings of the world in general. So, according to his philosophy all our notions about our existence etc. are beliefs (predicated on "consciousness" and we have no idea what that is)... beliefs which we need to give up or suspend in order to live at peace, without anxiety. We need to act and respond in the present experience of ourselves as entities perceiving now, and act (non judgementally) to do the best for other perceived entities and for our own health and wellbeing. Sounds good. However, he argues, to be able to function in our perceived world we need to behave "as if" some of these beliefs are true without actually believing them. Not sure I can get my head around this but I will certainly give it some thought (actually I may not be able to trust my own thought as it is mysterious as the rest of me). Seriously, I will read this book again and ponder on it, as it feels as though it might contain some grains of helpfulness.
