The phrase “structure of feeling” is attributed to

The correct option is Raymond Williams.

The term “structure of feeling” is a key concept in cultural studies coined by the influential Welsh academic, novelist, and critic Raymond Williams. He first introduced the phrase in Preface to Film (1954) and later developed it in detail in his seminal works The Long Revolution (1961) and Marxism and Literature (1977).
Williams defined a “structure of feeling” as the shared values, lived experiences, and emerging consciousness of a particular generation or historical period. It represents the felt, active, and lived aspects of social life that are still in process and have not yet been fully formalized or institutionalized into official ideologies or beliefs.
