A DILEMMA FOR SINNOTT-ARMSTRONG'S MODERATE PYRRHONIAN MORAL SCEPTICISM

In order for us to have epistemic justification, Sinnott-Armstrong believes we do not have to be able to rule out all sceptical hypotheses. He suggests that it is sufficient if we have 'modestly justified beliefs', i.e., if our evidence rules out all non-sceptical alternatives. I argue that modest justification is not sufficient for epistemic justification. Either modest justification is independent of our ability to rule out sceptical hypotheses, but is not a kind of epistemic justification, or else modest justification is a kind of epistemic justification, but is not truly independent of our ability to rule out sceptical hypotheses.     

CONTESTING PYRRHONIAN CONTRASTIVISM

I air three kinds of problem to which Sinnott-Armstrong's epistemological contrastivism seems to be exposed: (a) the theory gives an unplausible account of justification attributions; (b) the Pyrrhonism which results from its inability to identify relevant contrast classes bars us from epistemic responsibility; (c) contextualism does just as well as Pyrrhonism, despite Sinnott-Armstrong's arguments to the contrary.     

SCEPTICISM ABOUT PHILOSOPHY

Suppose a person who is agnostic about most philosophical issues wishes to have true philosophical beliefs but equally wishes to avoid false philosophical beliefs. I argue that this truth-seeking, error-avoiding agnostic would not have good grounds for pursuing philosophy. Widespread disagreement shows that pursuing philosophy is not a reliable method of discovering true answers to philosophical questions. More likely than not, pursuing philosophy leads to false belief. Many attempts to rebut this sceptical argument fail.     

POLITICAL LIBERALISM WITHOUT SCEPTICISM

Political liberalism famously requires that fundamental political matters should not be decided by reference to any controversial moral, religious or philosophical doctrines over which reasonable people disagree. This means we, as citizens, must abstain from relying on what we believe to be the whole truth when debating or voting on fundamental political matters. Many critics of political liberalism contend that this requirement to abstain from relying on our views about the good life commits political liberalism to a kind of scepticism: we should abstain from relying on our views about the good life because we should be uncertain about the truth of those views. But this kind of scepticism is itself a controversial epistemic position which many reasonable people reject, thus apparently making political liberalism internally incoherent. This is the sceptical critique of political liberalism. This paper shows the sceptical critique to be false. The paper argues that the epistemic restraint required of citizens in political liberalism does not assume or imply any version of scepticism about our ability to know the good life. Liberal neutrality is motivated not by scepticism about our own views, but rather by a desire to justify fundamental political principles to others. ¹ 1 I would like to thank Rebecca Stone, Steve De Wijze, and an anonymous referee for many helpful comments on earlier versions of this paper.

A CLOSER LOOK AT CLOSURE SCEPTICISM

The paper argues that there is no valid closure principle that can be used to infer sceptical conclusions. My argument exploits the Gettier Intuition that knowledge is incompatible with accidentally true belief. This intuition is interpreted as placing a constraint on beliefs that can count as knowledge: only beliefs which are based on reasons that are relevantly linked to the beliefs' truth can qualify as knowledge. I argue that closure principles are to reflect this constraint by accommodating the requirement that a subject's belief p needs to be based on her competent derivation of p from a known q . The emerging account is finally argued to reconcile Dretske's anti-closure intuitions with the intuition that we can extend knowledge by deduction, while simultaneously blocking closure arguments for scepticism about the external world.     

MORAL CONTEXTUALISM AND MORAL RELATIVISM

Moral relativism provides a compelling explanation of linguistic data involving ordinary moral expressions like 'right' and 'wrong'. But it is a very radical view. Because relativism relativizes sentence truth to contexts of assessment it forces us to revise standard linguistic theory. If, however, no competing theory explains all of the evidence, perhaps it is time for a paradigm shift. However, I argue that a version of moral contextualism can account for the same data as relativism without relativizing sentence truth to contexts of assessment. This version of moral contextualism is thus preferable to relativism on methodological grounds.
