 The Pyrrhonian use of the three modes of Agrippa in order to induce suspension of judgment can be presented in the form of an argument, which has been called “Agrippa’s trilemma”. It is at least somewhat misleading to present the Pyrrhonian position in terms of an argument, because when someone presents an argument they are usually committed to the truth of its premises and its conclusion, whereas Pyrrhonian skeptics would suspend judgment with respect to them. Nevertheless, presenting an argument for Pyrrhonian Skepticism doesn’t do much violence to this skeptical position, because what is important is not whether the Pyrrhonians themselves accept the premises or the validity of the argument, but rather whether we do. If we do, then it seems that we ourselves should be Pyrrhonian skeptics (and if we do become Pyrrhonian skeptics as a result of this argument, we can then start worrying about what to do with respect to the fact that an argument whose premises we believed—and perhaps still believe—to be true convinced us that we are not justified in believing anything). If we do not think that the argument is sound, then we stand to learn something interesting about the structure of an epistemological theory—because each of the premises of the apparently valid argument looks plausible at first sight.
