James was once praised by British novelist Joseph Conrad as "a historian who described a beautiful conscience", but his lack of profound understanding of politics and society and his occasional dabbling also reflected his conservative thoughts. He even satirized and mocked the progressive democratic movement. He ignored the social roots of moral quality and seldom described the social environment. Although he has a deep understanding of the upper class and is often critical, he knows little about the lower class and has a lot of spiritual aristocratic prejudice against people and things. His writing style is consistent with his ideological realm; Especially in later works, sentences are often long and complicated, and adverbs are used extensively to reflect the depth of thoughts and feelings carefully, accurately and appropriately. He has many innovations in artistic techniques, such as the so-called "angle" method, that is, he thinks that a writer can't know everything, and he can only tell stories and spread the plot through the "angle" of an insightful character in his works.
