There is a direct relationship between epistemology and one's attitude toward those with whom one disagrees. Those who think that the truth is difficult to ascertain can be expected, other things equal, to tend to tolerate (in the sense of sympathizing with) those with whom they disagree, as the blameless victims of an opaque reality. Those who think that the truth is easy to ascertain can be expected, other things equal, to tend to be intolerant (in the sense of being (...) unsympathetic) toward those with whom they disagree, who perversely refuse to acknowledge what should be clear to any well-intentioned inquirer. However, these tendencies toward tolerant or intolerant attitudes can be offset by other factors; and they do not, in any case, necessarily dictate whether one will favor tolerant or intolerant policies regarding those toward whom one feels tolerant or intolerant. The complex relationship between epistemology, tolerant or intolerant attitudes, and tolerant or intolerant policies is evident in the thought of prominent early-modern Protestant theologians who, under the pressure of rampant and violent religious disagreement, theorized tolerance.
