In Matthew Arnold’s essay “The Function of Criticism at the Present Time”, the essence of criticism is described as disinterestedness—which is why option 3 is correct. Here's a detailed breakdown of why this is Arnold’s key idea:
Disinterestedness in Arnold’s Criticism
Arnold argues that the critic's role is not to advocate for personal, political, or ideological agendas but to see things as they are, without bias or attachment. Criticism, in his view, should be guided by intellectual independence—detached from vested interests. He believed that the critic must approach art, literature, and ideas with a focus on truth and objectivity, striving for the free play of thought.
This disinterested pursuit of truth enables critics to assess literature and culture fairly, without being clouded by personal preferences or cultural pressures. Arnold insists that only through such impartial reflection can society advance intellectually.
