Benjamin Franklin's "The Way To Wealth" signifies the change from the "puritan plain" writing style to the "protestant work ethic" style. In fact, it wasn't just the writing style that changed, it was American values, traditions, nationalism, and culture that changed during this time as well. The popularity of The Way To Wealth showed that more and more Americans were concerned with higher levels of intellectual knowledge, than they did for futile religious dogma and rhetoric. Furthermore, Americans weren't so in love with being a colony of the British Empire, so this area in time also represented a gradual change in the American value of British nationalism, to American nationalism. Therefore, besides the fact that Americans were switching from the puritan faith to the protestant doctrine, they were also beginning to change their values in regards to education and British nationalism. The reason being, they no longer wanted education for the rich, but they wanted it for everyone and they weren't fond of being taxed like crazy by Great Britain.
Logos are the rhetorical appeal that Brutus used in his funeral address. The appeal to logic, on the one hand, includes persuasion by reason, which sounds the most powerful. On the other hand, it is good to cater to feelings while persuading individuals, as it is normal.
