Egregore (also egregor) is an occult concept representing a "thoughtform" or "collective group mind", an autonomous psychic entity made up of, and influencing, the thoughts of a group of people. The symbiotic relationship between an egregore and its group has been compared to the more recent, non-occult concepts of the corporation (as a legal entity) and the meme.
The first author to adapt "egregore" in a modern language seems to be the French poet Victor Hugo, in La Légende des Siècles ("The Legend of the Ages"), First Series, 1859, where he uses the word "égrégore" first as an adjective, then as a noun, while leaving the meaning obscure. The author seems to have needed a word rhyming with words ending in the sound "or". It would not be the only example of word creation by Victor Hugo. However, the word is the normal form that the Greek word ἑγρήγορος (Watcher) would take in French. This was the term used in the Book of Enoch for great angel-like spirits.
Eliphas Lévi, in Le Grand Arcane ("The Great Mystery", 1868) identifies "egregors" with the tradition concerning the "Watchers", the fathers of the nephilim, describing them as "terrible beings" that "crush us without pity because they are unaware of our existence."
The concept was featured in Corporate Metabolism series of articles by Paco Xander Nathan, which were published in 2001.
