suddenly i have very much warmed to experimental philosophy. once, i was skeptical or even dismissive, for one of the things that very much attracted me to philosophy was that, unlike in many less rigorous disciplines, you could do your research lying in bed, maybe with a bunch of books lying around, maybe not. but however, experimental philosophers are vindicating my theory of knowledge, which, if i'm recalling correctly, is profoundly radical yet mind-humpingly simple. i conclude from this that their research methods are unassailable. k=tb, baby.
one thing i'll say for 'knowledge is merely true belief' that perhaps i didn't say back in the day: it's pretty darn economical, oh, elegant really. i think knowledge is a richer notion than is captured in analytic epistemology. but let's restrict ourselves to an account of 'S (a person) knows that p (a proposition [or something that can be true or false])'. i actually am not quite sure how to value simplicity as a quality of theories; i am not sure that a simpler theory is likelier to be true than a complex one. but S knows that p iff S believes p and p is true (or 'S knows that p iff p and S believes that p') is an extraordinarily simple theory (iff is 'if and only if'), and i assert that it does a surprisingly good job of covering 'the phenomena', which i make out to be the ways the term is centrally or paradigmatically used in ordinary language. that it can do that is what i was arguing in my early papers, and the survey materials lend at least some support to that notion. the simplicity might be compelling at this point because of the baroque refinements to jtb-style approaches post-gettier.
[or, to review: the usual account of knowledge is jtb: justified true belief. obviously, tb is more economical. also, that little j thing or whatever we may call a similar condition, or multiplying conditions, begins to become truly rococo: dude it leads into endless labyrinths, worlds full of barn replicas.]
i generated k=tb in jim cargile's graduate seminar in epistemology at uva in the late 80s. it was explicitly an attempt to display the philosophical power of sheer perversity, a not entirely atypical bit of playful grandstanding: alright, what position is no one taking? i literally built a grid of theories and saw a big hole, and one thing about finding a fissure in the taxonomy like that is that if you jump in, you see a bunch of assumptions other people are making, which you then can try to undermine. but there could have been other perverse approaches and here's why i went for this one: it leans on truth like a mofo. as david sackris and james beebe put it, "bringing about the truth of p is (except in exceptional circumstances) not a task that falls to S. Rather, that 'task' falls to reality" (9). everyone at the time was willing to delete the truth condition; i had a lot of more or less rortyan gard contemporaries. my approach was designed to fit into a reality program. (cargile thought it was ridiculous, but in a great way or just the way i'd hoped: blasphemy! he cried, with a big old smile. also he always called me 'jean-paul'. he gave the final version for the class/first version for the world a 'B+', if i recall.)
another motivation at that moment, however, was that (almost secretly) i was reading kierkegaard, and really, as people sensed when the stuff angered them, i was going to try to derationalize knowledge; i was going to let your faith count as knowledge if its propositional content was true, i was going to encourage you to intuit, i was going to claim that even reason rested on faith, and so on. i was going to argue that there were many sources of knowledge, reason/science being only some, anarchizing epistemology. the main purpose of the papers was to take the sting out of the actual results, to show that it wasn't irrationalist at all. well, maybe it wasn't, necessarily, without some ancillary arguments. i was going to sneak all that up on you after i pulled the rational part out of the conceptual analysis of knowledge.
i did get more convinced of it as time went by; also it was my hobby to go here and there to defend it against various onslaughts, so it provided amusement if nothing else; i did delight in its perversity, or even in the fact that everyone thought it was ridiculous. some people - including some eminent epistemologists - became genuinely angry, which is also not the worst thing in the world necessarily. it was a bit of a performance piece, but people did sincerely think it was absurd. i started touring it to little conferences and stuff as a grad student and had worked it through a million counter-examples before the first version came out in american philosophical quarterly. i certainly had a notion that it would be my little reputation-maker, that i'd be associated with that idea primarily. i'm glad it didn't quite turn out that way, i suppose.
there was a little sensation at the time when the second paper came out in the journal of philosophy, i guess, and i do remember defending the whole thing in front of an angry auditorium at an apa; i remember robert audi getting pretty hostile, e.g. but really, the thing blew over. i think one problem is this: if k=tb, too many problems on which people have spent too much time do not arise. if it were true, it really would mean a lot of the epistemology of the last x decades (again, gettier and after) was barking up the wrong tree. it just had no place in the line of the discourse at that time, is another way to put it. it was one of a number of times i mistakenly thought that people would find it delightful to be provoked.
no one would publish my book on the topic, which must have been profoundly frustrating at the time. they sent it out specifically to be refereed by people who had already attacked the argument in one venue or another. for awhile, they were assigning my papers to grad students at arizona - a big center of analytic epistemology - as an exercise, like a take-home final: what has gone so terribly wrong with this argument? an object-lesson in sophism. i used to get some emails every year or two with refutations from grad students (always on the same predictable lines). i actually didn't hate that; i've always thought the whole thing was a fun little thing to play with, and it came from a grad seminar in the first place, for god's sake.
there has been a trickle of references to it, but really it just dissolved. in a way, that was ok; it let me go on to other things, like the political stuff; otherwise i might have spent a career on it. after some years i got profoundly tired of the same objections and replies, and really wanted to go write about art or something. sriously, for a very long time if i was walking the halls somewhere with a name tag, philosophers would snap their fingers, like 'aren't you that guy?' it got to where i'd be: have you read my stuff on race? i started pretending not to remember my own argument, and then i really started not remembering my own argument.
but i definitely also still feel that this sucker has legs. people are going to keep circling back to it, i think. there are problems, but there are strategies for dealing with them. i think beebe and sackris show some of these better than i did. if i myself were going to return to a defense, i'd need to bone up on my own arguments! also rethink some. also it would need to be put into relation to developments in epistemology since the early '90s, like the 'truth-makers' stuff and timothy williamson's work in epistemology, to which it is interestingly related.
i feel very distant from the person who generated this idea, so maybe if i could be permitted to comment on its strengths? it is still out there as a fundamental challenge. no one has dispensed with it. (people were relieved to regard lycan's attack as decisive. not even close, i say, as beebe and sackris point out. but lycan reviewed the manuscript for one publisher or another.) the fact that many important epistemological problems do not arise if k=tb is right is not necessarily, all things considered, a strike against it. i still endorse it as a theory within limits (man it's going to be a little hard to deal with 'propositions' in my later ontology), but there should at least be a longer line of debate about it.
