Here is a very stimulating place to visit, where one can begin or refine one's searches. It is wide in scope (there are plenty of related metaphysics and epistemology entries) with some original features (for example, it uniquely provides a series of profiles of key figures in the philosophy of mind) and an overall fresh approach. It deserves the description 'dictionary' insofar as every entry starts with a straightforward, three-line definition; however, as the project develops, more and more entries have long and substantial discussions attached, making it not different in format and ambition from the declared encyclopedias.

As a perfect celebration of the interdisciplinary character of cognitive sciences, this authoritative reference displays a great variety of high quality entries grouped into 6 sections (one being 'Philosophy'), spanning from the traditional ones, like a few offering profiles of some classical philosophers, to the more exotic and highly specialized. Authors are top experts in their fields. Minor defects are some overlapping and the cross-references not hyper-linked. All in all, it's a superb accomplishment.

The mind-related entries (not many so far), like everything here, are of the finest kind. Compared to the 'Mitecs' entries, they are obviously fewer in number (according to the plan), but sometimes longer, well articulated and exhaustive (from what can be viewed). Until now, it seems a little slow growing business, but no doubt a worth waiting for.
