A while back I had started to look into the history of our Philosophy Club. After giving up on individuals memories I recently had a dig through the archives under Auchmuty Library. I didn't find much, as I suspect that there is more material relevant to this gathering dust in various parts of McMullin building, but I did manage to extract a few key facts.
Officially, the Philosophy Club was founded in early 1966. I don't know if this is older than the Engineering Fraternity, which claims to be the oldest social club on campus, without ever giving an actual foundation date. (I doubt any of their members/ex-members can remember that far back). But I think we can safely claim to be the oldest Academic club on campus, even if we don't pre-date Autonomy (1965) as I had previously speculated.
As for the Dialectic journal, I have yet to pin down a firm first issue date, but the 2nd volume was published in 1968, so I think it seems fair to assume that Volume 1 was created in 1967. The archive has Volume 2, Number 1 (Feb 1968), the archivists and myself would be very keen to track down anything earlier.
I have been investigating other clubs similar to our own via the web, and many seem to have only lasted a few years, with a high rate of attrition apparent in over the last 10 years or so. In light of this, the age of 41 is an impressive figure.
