Information for Participants

(Last Modified: 12-Jan-2003.)

What is it?

The Critical Café is an email based open forum, operated by The Karl Popper Web.

It provides a meeting place for those interested in Popper's ideas to converse on an informal level. This may be especially useful for East European thinkers developing personal contacts with others in the West interested in Popper's idea of an Open Society--but the Café is open to all interested participants, and for the discussion of all aspects of Popperian philosophy. Not everyone with a genuine interest in Popper's work has the time to contribute serious articles, but would nevertheless like to be involved in the life of philosophical debate. He or she can do so in the Critical Café.

The Café can also be a place for trial-balloons or brainstorming sessions, where the emphasis is on free expression of even half-baked, incipient ideas that need a little cultivation before being developed into a substantial article.

The Café may be used for the dissemination of notices of interest to the community--such as announcements of relevant meetings or conferences, calls for papers, availability of preprints etc. However, we request that any given meeting or conference should be notified here at most twice--first with the initial call for papers, and then a final reminder with the programme.

Finally, The Critical Café can (and should) be used for discussion of The Karl Popper Web itself. Specifically, news of new services etc. will be announced here, and we encourage subscribers to provide feedback (critical or otherwise!) about any and all of the facilities provided by TKPW. We will be especially interested in suggestions for additional services, or enhancements of existing ones.
