Is this a cult?

(see photo). I have been seeing signs advertising the School of Practical Philosophy since I first moved to NYC in 2003. They are always either in subway stations or in the trains themselves. I suppose it is a good way to reach a wide, disparate audience quite likely disillusioned and searching for meaning, and perhaps wondering how it came to be crammed next to a a particularly malodorous person at that particular point in time, or wondering what mistakes in life destined it to be sitting next to a drunk, vomiting teenager (this has happened to me). Still, as much as I question my life choices when suffocating in the N train at rush hour or waiting 45 minutes for a D train at 2 AM, I have never been tempted to phone up the School of Practical Philosophy. A glance at the website, www.philosophyworks.org, doesn't really reveal much more than their advertisement, though it has the same vaguely creepy graphics with sun shining through clouds in a blue sky. They seem to offer courses in philosophy and economics for a fee, of course. But the whole thing feels cultish to me somehow. I am, however, happy to be proven wrong if any former or current students of the school want to speak up for it. I am also happy to be proven right if anyone wants to confirm that it is in fact a cult out to recruit vulnerable subway patrons.
