This one I found not on the internets, but in the Berkeley math library! John Burgess has a collection of philosophical papers out: Mathematics, Models, and Modality. It includes the classics “Why I am not a nominalist”, “Mathematics and Bleak House”, “Can truth out?”, and “Quinus ab omni noevo vindicatus”. Must buy, must read!
A collection of (admittedly seminal but) previously published papers that Cambridge sells for $99.00 ($79.00 for the e-Book version)? Is Cambridge channeling Springer?
