Combining Pragmatic and Alethic Reasons for Belief [Ch. 3 of _The true and the good: a new theory of theoretical reason_]

This chapter sets out a theory of how to weigh alethic and pragmatic (non-alethic) reasons for belief, or more precisely, to say how alethic and non-alethic considerations jointly determine what one ought to believe. It replaces my earlier (2008) weighing account. It is part of _The true and the good: a new theory of theoretical reason_, which develops a view, welfarist pluralism, which comprises central two theses. One is that there are both irreducibly alethic or epistemic reasons for belief and irreducibly pragmatic (and non-alethic) reasons for belief. The other is that despite this, the source of all normativity is pragmatic in a particular way, i.e. that all reasons are reasons in virtue of their being conducive to wellbeing. The pluralist theory of reasons emerges from the irreducibly plural nature of the components of wellbeing, on of which is being in a positively-valenced epistemic state. This view also offers some insight into outstanding problems concerning the scope, chronicity, and normativity of the requirements of theoretical rationality as well. (Updated 10 May 2022)
