Chesterton devotes a chapter to each of Shaw's personas: the Irishman, the Puritan, the Progressive, the Critic, the Dramatist, and the Philosopher. He admires the Irishman, he admonishes the Puritan, he picks apart the Progressive, he corrects the Critic, he exposes the Dramatist, and finally, he does all five things to the Philosopher. He calls Shaw the "most savagely serious man of his time" who takes even his jokes seriously.
