An American cannot converse, but he can discuss, and his talk falls into a dissertation. He speaks to you as if he was addressing a meeting; and if he should chance to become warm in the discussion, he will say 'Gentlemen' to the person with whom he is conversing.

In this quote, Alexis de Tocqueville, a French political thinker and historian, observes a distinct cultural characteristic of Americans in their style of communication. He notes that rather than engaging in a simple conversation, an American tends to engage in a discussion that resembles a formal dissertation. Tocqueville is commenting on the tendency of Americans to elevate casual dialogue into more structured, intellectual exchanges, even when they are speaking with just one person. This reflects a more formal and argumentative mode of communication, often characterized by an intellectual approach.

The phrase "He speaks to you as if he was addressing a meeting" highlights how Americans, in Tocqueville's view, often treat informal conversations as if they were public speeches or debates. This reflects the egalitarian and democratic spirit of American society, where individuals feel free to voice their opinions and engage in discourse in an open, sometimes formal manner, even in personal interactions. The idea of speaking as if addressing a group reveals a certain formality in American communication that may stand in contrast to other cultures with more relaxed, intimate conversation styles.

Tocqueville also humorously notes that if an American becomes particularly passionate during a discussion, they might refer to the person they are conversing with as "Gentlemen," as if speaking to a group of people. This indicates the tendency of Americans to carry an air of respect and formality even in one-on-one exchanges, emphasizing the seriousness with which they approach dialogue, regardless of the setting.

Alexis de Tocqueville is best known for his work "Democracy in America", where he analyzed American society in the early 19th century. His observations on American democracy and culture highlight both the strengths and contradictions of American life. This quote exemplifies his interest in how egalitarianism, individualism, and democratic ideals shaped American interactions and communication styles in ways that might seem unusual to people from other cultures.
