Natalia Huacar introduces the first part of the 'Introduction to Scientific Thinking' course, focusing on argumentation. Argumentation is presented as a linguistic activity crucial for critical thinking, used to persuade, resolve conflicts, answer questions, and comprehend phenomena.
The video defines arguments as collections of statements, which are linguistic entities. Statements are further defined as a type of sentence that asserts or denies something, making them verifiable as true or false. Examples are provided to distinguish statements from other types of sentences like questions or commands.
Not all sets of statements constitute an argument. An argument requires a specific structure: premises (reasons) that support a conclusion. The video illustrates this with an example about the oldest universities in Argentina, highlighting the role of indicator words like 'therefore' in identifying the conclusion.
The speaker explains that indicator words help identify premises and conclusions. Words like 'given that,' 'since,' 'because' signal premises, while 'therefore,' 'consequently,' 'in conclusion' indicate conclusions. Even without these indicators, the meaning of the text helps in discerning the argument's structure.
To recognize arguments, it's recommended to first ask if a text contains an argument, look for indicator words, and try to identify the conclusion first, as there's only one. Examples, including Galileo's discussions about Earth's movement and continental drift, illustrate how to apply these tips.
The video offers key warnings: arguments can be contained within a single sentence, and the conclusion is not always at the end; it can appear at the beginning or in the middle. The distinction between premises and conclusion is relative—what is a conclusion in one argument can be a premise in another. Also, there are no arguments without both premises and a conclusion, and complex arguments can contain sub-arguments, though this topic won't be explored deeply in this course.
