Strength and Decency, Theodore Roosevelt's speech, used a range of rhetorical tactics to encourage educated, mature, and strong men to become powerful and moral human beings. Roosevelt's goal in delivering this speech was to convince the audience to behave like the strong men they are, but with decency and manners, because men behaved in a highly manly manner in the 1900s. Men, on the other hand, lacked manners and morals.
