Meaning

James is not making a literal argument that these are the most useful or important words in English. He is instead describing a feeling, the way certain words, when placed together, carry a whole atmosphere inside them. The phrase "summer afternoon" conjures warmth, leisure, long light, and freedom from obligation. Saying it twice slows the reader down and lets the feeling settle, which is itself a small performance of what a summer afternoon actually does.

Context

James was famous for his precise and careful attention to the texture of experience, and this line is a good example of that attention applied to something as simple as a time of day. He was deeply interested in how language shapes perception, and the observation has the quality of a personal confession rather than a formal literary claim. It has been quoted widely over the years because it does exactly what it describes: it makes the reader pause and feel something pleasant at the sound of two quiet words.
