"A wise man proportions his belief to the evidence"
About this Quote
The subtext is quietly radical: most of what passes for certainty is a social habit, not an intellectual achievement. Hume wrote in the Enlightenment, when science was beginning to outmuscle inherited authority, but theology, superstition, and political loyalty still claimed automatic deference. His philosophy is famous for puncturing the idea that reason rules us; we’re driven by custom, feeling, and convenience. So this sentence doubles as a self-diagnostic: if your belief is fixed while your evidence shifts, you’re not reasoning, you’re performing.
It also anticipates modern fights over misinformation without sounding like a TED Talk. Hume isn’t saying “trust experts” or “follow the science” as slogans. He’s describing a discipline: demand receipts, weigh them, and let uncertainty remain when the evidence is thin. Wisdom, in his frame, looks less like having the right answers and more like resisting the human urge to turn hunches into holy writ.
