How do our experiences change us and our philosophical outlooks?
It is interesting that you speak of going through different phases at different ages. Strangely, I went through my Nietszche phase before I really questioned my religious background. However, I have generally preferred to see him as more of a poet than take his ideas literally, especially the idea of superman. It seems to be so ego inflated.
As you know, I am into the rock and alternative music and that has been as much as my worldview in relation to psychological change. I would say that it was during one of my most difficult periods that I embraced nu metal music and began going to dark metal live music events. It was while I was studying art psychotherapy, and the whole psychodynamic approach to life.
I also wonder about my question in relation to having worked in mental health care. I have seen people who have been driven beyond their breaking point. I do believe that some people don't just find books and music to cope. Of course, this is complex because it does depend on genetics and support structures people have. I do believe that we all have our limits as to what would be too much to cope with in some ways.
I often think about worse possible scenarios. My own are becoming blind or becoming homeless. Either could happen because I do have some minor retinal abnormalities and securing long term accommodation in London is extremely difficult. I do wonder how I would cope if one of these two ever occurred. But, it is quite likely that neither will happen and if they did I would cope better than imagined. It can sometimes be the unexpected smaller things which can be the stumbling blocks.
I am not sure that we are best thinking too much about the worst possible things which could happen too much. But, I think that it is useful to be aware of them partly as a way of thinking about life and the minor setbacks in proportion, and probably being grateful that the worst have not happened and possibly never will. I also think that the underlying philosophy of CBT can be useful for reflecting on experience in a critical but positive way.
