In contradistinction to the underestimation in the field of rocket science and the aerospace industry, Parsons' accomplishments in the arcane sciences have been highly overrated and grossly exaggerated. As a magician he was essentially a failure. As a Thelemite he learned the hard way what was required. He loved Crowley's 'Law' but couldn't adhere to it—though he tried harder than most. He violated the rules, undertook unauthorized and unorthodox magical operations, and claimed the grade of Magister Templi without first completing all the grades below it. He couldn't handle working under authority—his ego was too big. His record of failure is valuable in that regard. He was a great promulgator of thelemic ideals in his essays, but as an idealist his elitism ruined his work. Indeed, some would say he was guilt of hubris, which the gods always punish.
