Welcome to lucidphilosophy. I created this site for my students and anyone interested in philosophy. I am a philosophy professor in the United States.
Like my Youtube channel teachphilosophy, the purpose of this website is to explore philosophical concepts in a lucid, relevant and sometimes humorous way (attempted humor). 
This site currently has four sections:
1. Quizzes: Interactive quizzes are a fun and effective way to learn. As you answer each question, you will receive immediate feedback to help you master the concept. If you do poorly on a quiz, then you should read the corresponding chapter and complete the chapter exercises.
2. Logic course/book: Each chapter contains text, video, and practice activities to help you master essential logical skills like informal fallacies, formal fallacies, falsifiability, logical consistency, the two ways arguments go bad, scientific problem solving, thought experiments, deduction, induction, and the Socratic Method. 
3. Ethics course/book: In Progress.  These are my lecture notes and videos on various topics in ethics. Most chapters include a lecture and video. Some include questions and activities. 
4. Philosophy Course: Coming eventually. This is where I explore miscellaneous topics in philosophy like consciousness, mathematical realism, etc.
