"Bad company is as instructive as licentiousness. One makes up for the loss of one's innocence with the loss of one's prejudices"
About this Quote
The line works because it treats corruption as pedagogy. “Instructive” is the key Enlightenment verb, and Diderot aims it at experiences that official culture brands as mere vice. Bad company becomes a laboratory for seeing how people actually behave when the chaperones leave. Licentiousness becomes an education in desire, power, hypocrisy, and the gap between public virtue and private life. That’s not a celebration of debauchery so much as a refusal to grant bourgeois respectability a monopoly on wisdom.
The subtext is editorial in the deepest sense: Diderot, a chief architect of the Encyclopedie, spent his life fighting the idea that truth should be curated by priests, censors, and decorum. Here he’s editing morality itself, revising the cost-benefit analysis. Innocence is framed as a kind of ignorance with good branding; prejudice is ignorance with bad branding. Losing the first hurts your self-image. Losing the second expands your mind.
Context matters: in a world where the state and church policed bodies and books, arguing that “vice” can dismantle prejudice is a sly political claim. Experience, even the disreputable kind, can be an antidote to inherited certainties.
