After some research I have realised that my Dad’s predicament is not an uncommon situation with men of his age and circumstance. Across the internet there are articles and reports of similar occurrences, a common theme is that men feel a sense of loss when their perceived purpose is removed, and this in compounded as (generally speaking) many men of this generation feel that vulnerability is a sign of weakness,and so reject what it is they are experiencing.
There is a book I want to read surely, and I will recommend it to my dad if I think it will be helpful/enjoyable. It is written by Jungian analysts and called King, warrior, magician, lover. They define Jung’s four mature male archetypes – the king (the energy of just and creative ordering), the warrior (the energy of aggressive but nonviolent action), the magician (the energy of initiation and transformation), and the lover (the energy that connects one to others and the world) – as well as the four immature patterns (divine child, oedipal child, trickster and hero).
This to me sounds fascinating, and I imagine that there are some aspects that both my father and I would ideally develop. I’ll read and post a review on the blog when I have had the chance.
