"The sense of smell explores; deleterious substances almost always have an unpleasant smell"
About this Quote
The second clause is where the period’s confidence shows. "Deleterious substances almost always have an unpleasant smell" carries a lawyer’s hedging ("almost always") while still wanting the force of a rule. It’s Enlightenment-era common sense packaged as practical wisdom: nature, if read correctly, warns you. The subtext is moral as much as biological. Bad things advertise themselves; the discerning person learns to trust revulsion as a form of judgment. In a culture fascinated by classification - of plants, bodies, manners - odor becomes another taxonomy, separating the wholesome from the corrupt.
Context matters: Brillat-Savarin wrote in a France reshaped by revolution, urban crowding, and anxieties about contamination long before germ theory clarified what "bad air" really meant. Miasma thinking hovered in the background; smells were treated as both evidence and cause of illness. His line flatters the gourmand while defending him: attention to scent isn’t decadence, it’s prudence. The nose, he suggests, is where pleasure and self-preservation shake hands.
