1. Gurdjieff wrote a unique trilogy with the Series title All and Everything. The first volume, finalized by Gurdjieff shortly before his death and first published in 1950, is the First Series and titled An Objectively Impartial Criticism of the Life of Man or Beelzebub's Tales to His Grandson. At 1238 pages it is a lengthy allegorical work that recounts the explanations of Beelzebub to his grandson concerning the beings of the planet Earth and laws which govern the universe. It provides a vast platform for Gurdjieff's deeply considered philosophy. A controversial redaction of Beelzebub's Tales was published by some of Gurdjieff's followers as an alternative "edition," in 1992. On his page of Friendly Advice facing the first Contents page of Beelzebub's Tales Gurdjieff lays out his own program of three obligatory initial readings of each of the three series in sequence and concludes, "Only then will you be able to count upon forming your own impartial judgment, proper to yourself alone, on my writings. And only then can my hope be actualized that according to your understanding you will obtain the specific benefit for your self which I anticipate."
2. The posthumous second series, edited by Jeanne de Salzmann is titled Meetings with Remarkable Men (1963) and is written in a seemingly accessible manner as a memoir of his early years, but also contains some 'Arabian Nights' embellishments and allegorical statements.
3. His posthumous Third Series, written as if unfinished and also edited by Jeanne de Salzmann (Life Is Real Only Then, When 'I Am') contains an intimate account of Gurdjieff's inner struggles during his later years, as well as transcripts of some of his lectures. There is an enormous and growing amount written about Gurdjieff's ideas and methods but his own challenging writings remain the primary sources.
Reception and influence
Opinions on Gurdjieff's writings and activities are divided. Sympathizers regard him as a charismatic master who brought new knowledge into Western culture, a psychology and cosmology that enable insights beyond those provided by established science. On the other hand, some critics assert he was a charlatan with a large ego and a constant need for self-glorification. Gurdjieff had significant influence on some artists, writers, and thinkers, including Walter Inglis Anderson, Peter Brook, Kate Bush, Muriel Draper, Robert Fripp, Keith Jarrett, Timothy Leary, Dennis Lewis, James Moore, A. R. Orage, P. D. Ouspensky, Maurice Nicoll, Louis Pauwels, Robert S de Ropp, George Russell (composer), Jean Toomer, Jeremy Lane (writer), P. L. Travers, Alan Watts, Colin Wilson, Robert Anton Wilson and Frank Lloyd Wright.
