A July 1968 "Time" magazine study on hippie philosophy credited the foundation of the hippie movement with historical precedent as far back as the sadhu of India, the spiritual seekers who had renounced the world and materialistic pursuits by taking "Sannyas". Even the counterculture of the Ancient Greeks, espoused by philosophers like Diogenes of Sinope and the cynics were also early forms of hippie culture. It also named as notable influences the religious and spiritual teachings of Henry David Thoreau, Hillel the Elder, Jesus, Buddha, St. Francis of Assisi, Gandhi, and J.R.R. Tolkien.
