Synchronicity, Chance and Intention
Your questions do raise the question as to what extent are ideas related to autobiographical constructs? On this forum, it varies so much how much people disclose and it is probably more related to choice than anything else. But, it may also be connected to the expression of ideas as academic ones or in connection with experience. Some people write from a more detached point of view whereas others make more links with personal experience. One writer who has written philosophy more as an autobiographical expression is Bryan McGee. Jung himself wrote his autobiography, ' Memories, Dreams and Reflections', but this was towards the end of his life.
In connection with Jung and criticism of his work, his writings have been a source of inspiration for some but attacked fiercely by others. Of course, he was writing on psychoanalysis, but his writings explored so much more, especially in relation to esoteric philosophy, such as alchemy and Gnostic thinking, alongside reflections on his own clinical work.
From the standpoint of philosophy, he is a bit of a 'fringe' writer, and I think that this needs to be taken into account when thinking about his ideas about synchronicity. It would probably be hard for him to present his ideas in the cultural context of the twentieth first century, although a lot of people do write all kinds of ideas which appear in 'mind, body and spirit' sections of bookshops. Such ideas may be regarded as 'woo woo' by some, but there is academic philosophy, on the other hand, which can be seen as an intellectual pursuit. But, how real is the split in construction of thinking about experience and do the ones who write academic texts hide behind the cloak of theory, and how much is separate from the pursuit of philosophy as a way of making sense of life experiences? How much is the preference for the academic or other expression of written ideas bound up with an underlying personal philosophy position firstly?
