In 1957, New Republic editor Gilbert A. Harrison asked pioneering psychologist Carl Jung for his take on the “modern myth” of UFOs. From his reply:
[T]he problem of the Ufos is, as you rightly say, a very fascinating one, but it is as puzzling as it is fascinating; since, in spite of all observations I know of, there is no certainty about their very nature. On the other side, there is an overwhelming material pointing to their legendary or mythological aspect. As a matter of fact the psychological aspect is so impressive, that one almost must regret that the Ufos seem to be real after all. I have followed up the literature as much as possible and it looks to me as if something were seen and even confirmed by radar, but nobody knows exactly what is seen. In consideration of the psychological aspect of the phenomenon I have written a booklet about it, which is soon to appear. It is also in the process of being translated into English. Unfortunately being occupied with other tasks I am unable to meet your proposition. Being rather old, I have to economize my energies.
Colin Marshall comments:
Jung, as you can see, doubled his own interest in the subject by not only considering flying saucers a social phenomenon, but as a real physical phenomenon as well. Serious enthusiasts of both Jung and UFOs might consider bidding on the original letter, now up for auction. Estimated sale price: $2,000 to 3,000.
