Although Man and Superman can be performed as a light comedy of manners Shaw intended the drama to be something much deeper, as suggested by the title. This title comes from Friedrich Nietzsche's philosophical ideas about the "Übermensch" ("Superman"). The plot centers on John Tanner, author of "The Revolutionist's Handbook and Pocket Companion," which is published with the play as a 58-page appendix. Tanner is a confirmed bachelor despite the pursuits of Ann Whitefield and her persistent efforts to make him marry her. Ann is referred to as "the Life Force" and represents Shaw's view that in every culture, it is the women who force the men to marry them rather than the men who take the initiative.
Roebuck Ramsden is in his study, opening the morning letters. The study, handsomely and solidly furnished, proclaims the man of means. Not a speck of dust is visible: it is clear that there are at least two housemaids and a parlormaid downstairs, and a housekeeper upstairs who does not let them spare elbow–grease. Even the top of Roebuck's head is polished: on a sunshiny day he could heliograph his orders to distant camps by merely nodding. In no other respect, however, does he suggest the military man. It is in active civil life that men get his broad air of importance, his dignified expectation of deference, his determinate mouth disarmed and refined since the hour of his success by the withdrawal of opposition and the concession of comfort and precedence and power. He is more than a highly respectable man: he is marked out as a president of highly respectable men, a chairman among directors, an alderman among councillors, a mayor among aldermen. Four tufts of iron–grey hair, which will soon be as white as isinglass, and are in other respects not at all unlike it, grow in two symmetrical pairs above his ears and at the angles of his spreading jaws. He wears a black frock coat, a white waistcoat (it is bright spring weather), and trousers, neither black nor perceptibly blue, of one of those indefinitely mixed hues which the modern clothier has produced to harmonize with the religions of respectable men. He has not been out of doors yet to–day; so he still wears his slippers, his boots being ready for him on the hearthrug. Surmising that he has no valet, and seeing that he has no secretary with a shorthand notebook and a typewriter, one meditates on how little our great burgess domesticity has been disturbed by new fashions and methods, or by the enterprise of the railway and hotel companies which sell you a Saturday to Monday of life at Folkestone as a real gentleman for two guineas, first class fares both ways included. How old is Roebuck? The question is important on the threshold of a drama of ideas; for under such circumstances everything depends on whether his adolescence belonged to the sixties or to the eighties. He was born, as a matter of fact, in 1839, and was a Unitarian and Free Trader from his boyhood, and an Evolutionist from the publication of the Origin of Species. Consequently he has always classed himself as an advanced thinker and fearlessly outspoken reformer.
