Study Philosophy together

Study philosophy together:
As most of you know, I now organize two philosophy groups in parallel, with most of the "action" in the other group, the 'Singapore Philosophy Group', where we have lively debates every 4 weeks or so.
I wonder if there are some who would like a chance for a slower but more in-depth approach, perhaps where we read a philosophy text (book or article) together? I have been in this kind of group before and it has worked well, depending a bit of course on the book and enough people being willing to lead the discussion. We might meet fortnightly or monthly. Inviting professional philosophers to lead would also be a possibility, though from previous experience they usually can only do a one-off.
If you might find this interesting and worthwhile, come and chat; we will probably try and decide how to work together in the first session, and then come back to start the learning in the next session. Much depends on a good choice of book. So cast your mind back - what did you always want to read again or read with others so you could really get to grips with the ideas? And of course, what are we prepared to buy?
