The subject is the moral de-evolution of the human race.
Twain uses Darwin's theory of the evolution of man as a pretext to put forward his opposite theory.
Twain speaks to the entire human race and/or the general public.
Twain wants to challenge the accepted view that humans are superior to animals and make people think about their collective behavior.
Twain appears thoughtful and intelligent; he is also cynical and exhibits a keen sense of humor. He often uses witty writing and proposes a scientific point of view.
He has a negative tone shown by words such as: damned, incurably foolish Gloomy: He makes it sound like the point of no return is approaching, says things like the descent of man from the higher animals Hostile: He attacks the subject harshly, "indecency, vulgarity, obscenity--these are all strictly confined to man." Sarcastic: The whole piece has a sarcastic tone-"seems to suggest that the earl was descended from the anaconda and ha lost a good deal in the transition."
It is organized as an argumentative essay. It starts with the main idea and backs it up with reasoning and evidence. It is written to be attention grabbing and dramatic.
Satire: Used to draw attention the main ideas of the piece
Irony: Goes beyond what is needed to convey his point to the audience Hyperbole: All of the 'experiments' he conducts are exaggerated for effect, as are many of his statements. Metaphor: He makes opposite metaphors, comparing animals to the ideal view of man and men to the stereotypical animal.
