BTW just to make it clear re. recent posts about academic referencing: I wasn't referring to anyone personally - Susanna or anyone else. This forum seems an eminently civilised place, unlike a few other cyber-spaces I've wandered into. Its one thing I like about it. Philosophical discourse is one thing; personal remarks are something else, and I am also included in this equation. So referencing....philosophical or otherwise, but especially in philosophy, I think: I know its the way academia works, and I do it myself. However if philosophy is a method where the conceptual tools are themself examined - amongst other things - then my remark has to be seen in that context. In which they were intended. Et cetera. Onwards...
