"Faith consists in believing when it is beyond the power of reason to believe"
About this Quote
The intent is classic Voltairean pressure-testing. He isn’t neutrally describing religious life; he’s exposing what he saw as its dependence on suspension of judgment. The subtext reads like a dare to Enlightenment readers: if you prize rational inquiry, why celebrate a mode of thinking that begins where inquiry ends? At the same time, he’s canny enough to phrase it as taxonomy rather than attack. That’s how the sentence survives: it can be quoted by believers as a statement of spiritual courage, even as skeptics hear it as an indictment of credulity. Voltaire builds a rhetorical trap that lets both sides walk in willingly.
Context matters. Writing in an era when church authority policed public life and metaphysics elbowed out science, Voltaire made a career of defending toleration and mocking superstition, often under censorship’s shadow. This line performs that balancing act: it’s short, portable, deniable - and devastating. It reframes faith not as a higher kind of knowing, but as a workaround for not knowing, which is exactly the Enlightenment nerve he wanted to hit.

The English line “Faith consists in believing when it is beyond the power of reason to believe” appears to be a later English rendering/variant of Voltaire’s French sentence in the article « Foy/Foi » from the Dictionnaire philosophique. The primary-source wording in Voltaire is the French above.
