Life & Wisdom Quote by Voltaire

"Faith consists in believing when it is beyond the power of reason to believe"

About this Quote

Voltaire’s line is a compliment that lands like an insult. “Faith,” he suggests, isn’t a noble partner to reason; it’s what you reach for when reason taps out. The phrasing is surgical: “consists in” reduces faith to a single function, while “beyond the power of reason to believe” paints belief as an act that must overpower the mind’s own limits. It’s a definition that quietly smuggles in a verdict: if you need faith, you’re already in territory where evidence can’t do the job.

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.

Evidence:
La foi consiste à croire non ce qui semble vrai, mais ce qui semble faux à notre entendement. (Article: « Foy » (also spelled « Foi » in later printings); 6e éd., tome 1, p. 265 (Wikisource facsimile page)). 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. For first-publication bibliographic details of the work’s first edition: the Morgan Library catalog describes the first edition as dated [1764], with fictitious imprint “Londres” but actually Geneva, and identifies Cramer/Geneva in brackets. (Morgan Library record: https://www.themorgan.org/printed-books/175360). A Folger Shakespeare Library catalog record likewise gives “Londres [i.e. Geneva], 1764” and notes the imprint is false and printed in Geneva. (Folger record: https://catalog.folger.edu/record/858742).
