Agreed. I know that when I'm talking with philosophers I tend to use their special prepositions ("On X's view...", "Y consists in...") to sound more in-groupy and thus give extra weight to my arguments.

Yeah, my philosophy classes had a lot of people who would skip over discussions by using a well-known name. This is similar to what Andrew's You don't need Kant post was talking about.

That being said, the other extreme is not terribly useful, either. I have trouble remembering philosopher's names because the arguments and logic are more interesting and I never bothered associating it with the person who was speaking. As it turns out, I spend a lot of time going over ground that has already been covered because I did not learn the shortcut term.

This could be seen as a counter-point to my comment above.
