Key passages
“the other nerves scattered over the tongue and the parts in its vicinity are diversely moved by the particles of the same bodies, separated from each other and floating in the saliva in the mouth, and thus cause sensations of diverse tastes according to the diversity of figure in these particles.”
The nerves on the tongue and nearby areas are moved in different ways by tiny particles from food that mix with saliva, and this movement creates different taste sensations depending on the shape of those particles.
Descartes explains taste as a mechanical process where particle shape determines sensory outcome.
