“Men and women ... must be nothing more than post-horses”

“Men and women ... must be nothing more than post-horses” is Claire de Beauséant’s image for the instrumental treatment of people in the pursuit of social success. Addressing Eugène de Rastignac, she urges him to use each connection as a temporary means of progress, then leave it behind when it can no longer carry him toward his goal.

The Metaphor and Its Advice

Claire frames ambition as a journey toward a destination, with human relationships recast as a succession of mounts. Her instruction to take a fresh relay and leave the last behind makes advancement depend not on loyalty but on replacement: a person’s value is measured by how far that person can help the ambitious traveler go. The metaphor compresses a broad code of conduct into a practical image of use and disposal.

Social Success as Calculation

The advice belongs to a larger argument about how power operates in Parisian society. Claire tells Eugène that success requires cold-blooded calculation and warns that a young, wealthy woman of the world can provide the social connection he needs. Her counsel therefore makes the post-horse image more than a general cynicism about human nature: it applies directly to relationships cultivated for access and advancement.

Yet Claire also distinguishes calculation from emotional exposure. She advises Eugène to keep any genuine affection hidden, since an ambitious person who loves openly risks becoming vulnerable rather than remaining in control. The metaphor’s hard efficiency is thus set against the possibility of attachment: a heart, if present, must be carefully guarded from the same world in which people are treated as replaceable instruments.

The Image’s Warning and Significance

The figure is both instruction and warning. Claire offers it as a way to reach the goal of ambition, but her surrounding counsel reveals the cost of adopting it: suspicion becomes a safeguard, affection a liability, and other people’s worth a matter of usefulness. The image gives social climbing the shape of a relentless journey, where progress is purchased by abandoning those who have served their turn.
