Volume 6.7 of The Journal for the History of Analytical Philosophy (JHAP) has now been published online, with full open-access.

It features an article by Stefania Centrone and Mark Siebel entitled “Collections in Early Bolzano.” Here is an abstract:

There are quite a few studies on late Bolzano’s notion of a collection (Inbegriff). We try to broaden the perspective by scrutinising the forerunner of collections in Bolzano’s early writings, namely the entities referred to by expressions with the technical term “et”. Special emphasis is laid on the question whether these entities are set-theoretical or mereological plenties. Moreover, similarities and differences to Bolzano’s mature conception are pointed out. We argue that early Bolzano’s particular blend of set-theoretical and mereological features is best interpreted as a set-theoretically enhanced mereology.
