Pretty sure Jung was Jєωιѕн, psychology and psychiatry are most likely Jєωιѕн pseudo-science with some degrees of truth to them.
No, he wasn’t Jєωιѕн. His family was part of the Swiss Reformed Church though he was to become basically a pantheist.
I don't even know how to proceed. Is psychology just a completely irrational science? Is the study of the human will, intellect, and emotions all of the occult? Where is the Catholic thought on this? I read one Catholic book, written by a priest I think, and it had hardly anything on the phlegmatic.
I was employed at the front desk of a London Jungian Institute for 2 years. (It was ecuмenical). I loved it and found it fascinating at the time. No, psychology is not a completely irrational science but it is much misused.
I can’t answer about Catholic thought but I believe it is applicable in the Catholic situation.
Beware, just because a book is written by a Catholic priest doesn’t make it worthwhile reading, though of course you know this already.
