"Reason is, and ought only to be the slave of the passions, and can never pretend to any other office than to serve and obey them"
About this Quote
The subtext is less anti-intellectual than anti-self-deceit. Hume isn’t praising impulsiveness; he’s stripping away the comforting story we tell ourselves after the fact. Reason “pretend[s]” to command because we like thinking our choices come stamped with impartial authority. In practice, reason mostly functions like a good press secretary: it marshals evidence, invents coherence, and sanitizes motives that began elsewhere. That cynicism is the point. It’s a warning about how easily “rational” justifications become moral cover for what we already want.
Context matters: Hume is writing against thinkers who grounded morality in pure reason and treated passions as noise to be silenced. He instead locates moral judgment in sentiment and habit, making ethics a social and psychological project, not an algebra problem. The line still stings today because it explains both our personal contradictions and our public ones: technocratic arguments don’t persuade unless they touch identity, status, and belonging. Reason can map the route; passion chooses the destination.
