Premise and Conclusion
Lessons
Introduction to learning what an argument is, what a conclusion is, and what premises are. You will also learn how to identify premises and conclusions in arguments. Logical arguments consist of statements - sentences that assert something, capable of being true or false. Statements can be in forms of declarative sentences, questions, commands, requests or in form of exclamatory sentences. In this section, learn more about statements and understand other type of statements like ambiguous statements and rhetorical questions. This course is all about developing skills to evaluate whether arguments are good or bad. In this section, learn about different types of non-arguments with several examples. Quite often, an argument will not explicitly state a premise that we can see is needed in order for the argument to be valid. In such a case, we can supply the premise(s) needed in order to make the argument valid. Non-deductive arguments are deductively invalid because the truth of the premises does not guarantee the truth of the conclusion. What makes an argument strong or valid? In this lesson, learn the components of a good argument and how to determine the validity and strength of arguments by evaluating its true premises that are more plausible than its conclusion.
