Material for Thought began under the direction of John Pentland and was published sporadically by members of the Gurdjieff Foundation of California from 1972 until 2000. It started primarily with book reviews and over the years added excerpts, essays, articles, and poetry by noted authors, scholars and experts in their fields. 
 
Those who produced it were concerned with an inner search for meaning and in their own words they ask: “What does it mean to be practical, spiritually? Surely the real sense of community, so universally wished for, cannot exist without each of us learning to think.”
