Learn critical thinking and logical reasoning to create valid arguments, avoid logical fallacies, and solve real-world problems using tools like if-then implications and Aristotle’s logic.

Critical and logical thinking are essential in today’s democratic society and professional organizations. This course lays a foundation for these skills by embedding logic into everyday language and situations.

You will learn to create logically valid arguments, recognize and avoid logical fallacies, and focus on the form of an argument rather than its content. You’ll explore how to prove the validity or invalidity of arguments and understand the historical development of logic from Aristotle’s syllogism to modern predicate logic.

By the end of the course, you’ll be equipped to tackle real-world problems more effectively using logical operators, if-then implications, and other tools in logical reasoning. You’ll gain skills in using logic and language judiciously in both your professional and civic life.

Logical Thinking

"To be, or not to be..." contemplates Hamlet, and by asking such a childlike question, Shakespeare also ends up making a remark about the structure of reality, that we can't be in two opposing states at the same time.





Just as physics has laws that act on every physical object, and it's physically impossible to escape these laws, so does the world of logic.

There are some laws of thought that the cognitive objects in our mind must obey. There'd be chaos in our world otherwise. In the world of binary logic that we’re navigating, there are some situations that just can't be in any other way. And because of these laws, some situations can never be. Let's turn to a real-life case study in order to understand these laws.
