   Format: MarkdownItexI've just been reading the [MacTutor biography of Bolzano](http://www-groups.dcs.st-and.ac.uk/~history/Biographies/Bolzano.html) and I find it quite incredible the number of things he anticipated (more than I knew of, and I knew he worked out things Cauchy gets credit for). I would be interested if there was anything of particular interest to people here in his four-volume _Wissenschaftslehre_. See eg [Wikipedia](https://en.wikipedia.org/wiki/Bernard_Bolzano#Introduction_to_Wissenschaftslehre) for some section outlines. Digitised versions: [vol 1](http://dml.cz/handle/10338.dmlcz/400454), [vol 2](http://dml.cz/handle/10338.dmlcz/400475), [vol 3](http://dml.cz/handle/10338.dmlcz/400490), [vol 4](http://dml.cz/handle/10338.dmlcz/400504). In particular, he had what seems to be good views on mathematical foundations, but perhaps didn't have the weight of material that the later foundationalists (Frege, Cantor, Russell, Zermelo) had access to.
