You never step in the same river of thought twice, because neither you nor it are the same. - Jacques Barzun

Like Rousseau, whom he resembles even more than he resembles Voltaire, Shaw never gave a social form to his assertiveness, never desired to arrive and to assimilate himself, or wield authority as of right.

On reflection, moral judgment in the arts appears rather as a tribute to their power to influence emotion and possibly conduct. And reflecting further on what some critics do today, one sees that a good many have merely shifted the ground of their moralism, transferring their impulse of righteousness to politics and social issues.

Shaw knows at any moment, on any subject, what he thinks, what you will think, what others have thought, what all this thinking entails; and he takes the most elaborate pains to bring these thoughts to light in a form which is by turns abstract and familiar, conciliatory and aggressive, obvious and inferential, comic and puzzling. In a word, Shaw is perhaps the most consciously conscious mind that has ever thought — certainly the most conscious since Rousseau; which may be why both of them often create the same impression of insincerity amounting to charlatanism. Yet it is by excess of honesty that Shaw himself lent color to his representation as an inconsequential buffoon bent on monopolizing the spotlight.
