Whatever his blood type was and whether or not it was an Rh- one, Carl Jung was the first to coin and bring to light many phenomena.
Synchronicity, empathy, intuition and dreams were ongoing themes in his works.
What helps when reading anything from him is letting go completely of what we have learned wrong first. The media loves to create “geniuses”, but those who discover seem to understand the origin of it all.
Nobody “discovered” the wheel.
Some managed to adjust to what is without having been taught.
It is the difference between intuitive and trained minds.
Many perform based on what others taught them. Others are not satisfied with it. Their search for the not-yet-discovered is an endless road with many great stops along the way.
