Hi Ratbag,
Hopefully, I'm going to get this American woman's thesis, where she does a tranlsation of Cogitis Me. So I don't think I'll need your friend's help (although if the thesis thing falls through...). Also, the edition of Cogitis Me that is currently the 'correct' one in use by academics is not available in electronic format. It's 50 pages, and the woman at the photocopying place in the library would only allow me to copy 7 pages (in accordance with copyright law). So emailing it isn't really possible.
Anyway, I'll let you know what happens one way or another. Fingers crossed!
Thanks,
Hild
