Specific information about this course and its requirements can be found below. For more general information about taking Saylor Academy courses, including information about Community and Academic Codes of Conduct, please read the Student Handbook.
Improve your practice of nearly every major discipline, from the physical sciences and medicine to politics, law, and the humanities, by learning how to think critically and reason through problems.
This course will introduce you to critical thinking, informal logic, and a small amount of formal logic. Its purpose is to provide you with the basic tools of analytical reasoning, which will give you a distinctive edge in a wide variety of careers and courses of study. While many university courses focus on the presentation of content knowledge, the emphasis here is on learning how to think effectively. Although the techniques and concepts covered here are classified as philosophical, they are essential to the practice of nearly every major discipline, from the physical sciences and medicine to politics, law, and the humanities.
The course touches upon a wide range of reasoning skills, from verbal argument analysis to formal logic, visual and statistical reasoning, scientific methodology, and creative thinking. Mastering these skills will help you become a more perceptive reader and listener, a more persuasive writer and presenter, and a more effective researcher and scientist.
The first unit introduces the terrain of critical thinking and covers the basics of meaning analysis, while the second unit provides a primer in analyzing arguments. All of the material in these first units will be built upon in subsequent units, which cover informal and formal logic, Venn diagrams, scientific reasoning, as well as strategic and creative thinking.
This course includes the following units:
- Unit 1: Introduction and Meaning Analysis
- Unit 2: Argument Analysis
- Unit 3: Basic Sentential Logic
- Unit 4: Venn Diagrams
- Unit 5: Fallacies
- Unit 6: Scientific Reasoning
- Unit 7: Strategic Reasoning and Creativity

Tips for Success
PHIL102: Introduction to Critical Thinking and Logic is a self-paced course, which means that you can decide when you will start and when you will complete the course. There is no instructor or an assigned schedule to follow. We estimate that the "average" student will take 40 hours to complete this course. We recommend that you work through the course at a pace that is comfortable for you and allows you to make regular progress. It's a good idea to also schedule your study time in advance and try as best as you can to stick to that schedule.
Learning new material can be challenging, so we've compiled a few study strategies to help you succeed:
- Take notes on the various terms, practices, and theories that you come across. This can help you put each concept into context, and will create a refresher that you can use as you study later on.
- As you work through the materials, take some time to test yourself on what you remember and how well you understand the concepts. Reflecting on what you've learned is important for your long-term memory, and will make you more likely to retain information over time.
