Cartier-Bresson is often quoted so much that the substance can get buried under reputation. These lines keep the focus on the things that mattered most to him: perception, timing, restraint, and the discipline of seeing clearly.

To photograph is to place head, eye, and heart on the same axis.

The decisive moment is recognition.

Sharpness is a bourgeois concept.

Photography is an immediate reaction.

The eye must work with the mind.

Geometry matters.

Timing is everything.

You have to live life.

Do not crop your life.

The photograph is a fraction of a second with meaning.

Cartier-Bresson's influence survives because the advice is still practical. His best lines are about attention, restraint, and the exact instant when a scene becomes a picture.
