Objects as Useful Categories

Objects as Useful Categories
A reassuring world
Roquentin once recognized things by their qualities and uses, treating names as adequate guides to what objects were. Such classifications let him handle the world without confronting its bare presence.
Existence stays unnoticed
The ordinary system makes objects seem like scenery rather than independent realities. Its usefulness conceals a deeper question: why are these things here at all?
Names Lose Their Grip

Names Lose Their Grip
A seat becomes strange
Roquentin looks at a tram seat and can no longer make the word match the thing. The object’s material presence feels excessive compared with the category that once made it familiar.
Classification proves shallow
The names still exist, but they no longer settle his experience. He feels surrounded by things that remain present without needing to conform to the meanings people assign them.
The Root Exceeds Its Function

The Root Exceeds Its Function
A thing without explanation
The chestnut root is more than a plant part performing a biological function. Roquentin encounters its color, form, and presence as realities that no explanation can fully reduce.
The distinction becomes lived
Existence is not an added quality that leaves an object unchanged. It is the overwhelming fact that the root is there, making familiar essences seem like a thin surface over contingent presence.
