Abstract
Evidentialism as Earl Conee and Richard Feldman present it is a philosophy with distinct aspects or sides: Evidentialism as a conceptual analysis of epistemic justification, and as a prescriptive ethics of belief. I argue that Conee and Feldman's ethics of belief has 'weak roots and sour fruits.' It has "weak roots" because it is premised on their account of epistemic justification qua synchronic rationality, and this is neither necessary nor sufficient for knowledge. Also, Conee and Feldman's thesis O2 (An agent ought to always have just exactly that attitude towards a proposition supported by his / her evidence at that particular moment) is not support by in their “Ethics of Belief” article by V3 (Being synchronically rational at every moment is uniformly what it is to constitute epistemic success and to maximize epistemic value). That austere ethics of belief has "sour fruits" because the austere evidentialist ethic of belief is unable to support reasonable disagreement, and conflates psychographic contrareity epistemic fault or irrationality. The "hard line" and universal agnostic suspension it takes as the only rational stances of disagreement are really caricatures of different extreme responses to contrareity found among dogmatists and skeptics, respectively. I contrast this with John Rawls' understanding of "reasonable pluralism" and of the many sources of faultless disagreement over what Rawls termed comprehensive conceptions of the good.
