 Worse still, some philosophers maintain that degrees of belief are the only doxastic attitudes that are, in some sense, “real”, or at least the only ones that genuinely matter. According to them, only degrees of belief are deserving of a place in our most promising accounts of both theoretical (broadly Bayesian) and practical (broadly decision-theoretic) accounts of rationality. Full belief talk is either to be eliminated altogether (Jeffrey 1970), or reduced to talk of degrees of belief (ontologically, explanatorily or otherwise). Others still acknowledge that the concept of full belief plays an indispensable role in our folk-psychological practices, but nevertheless deem it to be too blunt an instrument to earn its keep in respectable philosophical and scientific theorizing (Christensen 2004). Virtually all such “credence-first” approaches have in common that they threaten to eliminate the normative role of logic, which is superseded or “embedded” (Williams 2015) in probabilism.
