This is a pretty odd paper. At first i was very critical of it. But its really a hard job to diagnosticize what is wrong with filosofy, exactly becus filosofy is so many different things. it seems like a catch-all category of whatever didnt fit in other disciplines. there is some truth to this, which is why things like astrology are sometimes categorized as filosofy. but there are also clear subfields of filosofy, which have different things wrong with them. the author gives a reasonable first hatchet job at categorizing these and noting what is wrong with them. worth reading if one likes metafilosofy.
