"Man is so made that when anything fires his soul, impossibilities vanish"
About this Quote
“Impossibilities vanish” is the quote’s seductive magic trick. It doesn’t say obstacles are removed; it says they disappear. That’s not a description of the world changing so much as perception changing. La Fontaine is capturing the psychology of conviction: once desire, faith, ambition, or rage hits a certain temperature, the mind revises the limits of the plausible. That can birth art, discovery, courage. It can also birth catastrophes, because the same mental furnace that makes a person attempt the unthinkable makes them ignore the unthinkable costs.
Context matters: a 17th-century French writer working under monarchy, patronage, and tight social constraints knew how often “impossible” really meant “forbidden,” “impolite,” or “dangerous.” Passion becomes a workaround, a private authorization. The line is aspirational enough to be quoted on posters, but its sharper edge is La Fontaine’s: human beings don’t merely overcome limits; they are experts at burning past them, and calling the smoke a miracle.

| Source | Verified source: Fables (Livre VIII): « Les deux Chiens et l’Âne mort » (Jean de La Fontaine, 1678)
Evidence: L'homme est ainsi bâti : quand un sujet l'enflamme, L'impossibilité disparaît à son âme. (Livre VIII, fable 25 (« Les deux Chiens et l’Âne mort »)). The English line (“Man is so made that when anything fires his soul, impossibilities vanish”) is a translation/paraphrase of these two French alexandrines. The quote occurs verbatim within La Fontaine’s fable « Les deux Chiens et l’Âne mort », which is commonly cataloged as Book VIII, fable 25. Multiple secondary pages identify the fable as belonging to the 1678 volume (Book VIII) of the expanded Fables collection (“Fables choisies…”, volumes published 1678–1694), e.g., an explainer page that explicitly states Book VIII belongs to the second tome published in 1678. ([chien.com](https://www.chien.com/culture/les-deux-chiens-et-l-ane-mort-la-fontaine-24772-12575.php?utm_source=openai)) For primary-source-grade verification of “first published”, the next step would be to consult a scan of the 1678 printed edition (or a critical edition) and capture the exact page number; the web sources I found reproduce the text but don’t provide the original 1678 page foliation.
