Where's the Boundary?
I recall two distinct conversations with fellow philosophy friends on the subject of philosophy and logic, where both have rather interesting implications for philosophers, and what we do:
(1) S mentioned to me that if logic is a part of philosophy, then arguments (as part of logic) fall under philosophy. That said, do we want to consider folks that argue their points (whether or not they do well according to the lights of logic) as doing philosophy? For example, should we call scientists/politicians/scholars, etc., who argue for their views philosophers?
(2) N mentioned to me, where I found a non-philosopher's argument lacking according to the lights of logic (though it isn't relevant here exactly how), that I shouldn't hold non-philosopher's arguments to the same logical standard as that of philosopher's arguments. That is, I should overlook the logical deficiencies, wherever they might be, and remember that the author of the argument wasn't a philosopher, so that this feature takes them off the radar of logical scrutiny, as far as the argument in question goes. But, if N is right, then doesn't this leave logic to the assessment of only philosopher's arguments?
Now for the interesting implications:
In (1) S's argument makes the category of philosopher too broad, for certainly we don't want to admit any person who happens to use the logical rigor of argumentation into the philosophical fold, for there is something more to being a philosopher than simply making (good or bad) arguments. But what might function as a plausible premise for this assertion?
In (2) N's point seems to limit logic to the point of almost trivializing it. Logic should be more than simply the assessment of philosopher's arguments, but all arguments, both good and bad, made by all folks everywhere, which includes the category non-philosopher, whatever that might be. But can an argument be made in support of this without (methodologically or otherwise) begging the question?
It seems to me that we might want to consider defining what philosophers are and what such folks do. I seem to recall calls for papers on such subjects a few years back. Naturally, if we define philosopher broad enough, we can deal with (1) and (2) in one fell swoop, for if we are all philosophers, then logic pertains to all our arguments. But we might want to avoid this conclusion, and opt for some other way, since it would be hard to consider all folks as philosophers. At the same time, though, we need to keep the application of logic on the broadest level possible, so as to pertain to all arguments, not just those belonging to philosophers. So, what should be done about all this?
