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.
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, deduction, induction, symbolic logic, and the Socratic Method.  I don't think the most important truths in life can be solved by logic or science, they must be experienced. Still, logic and science are excellent tools for discovering empirical truths and patterns. Like hammers, they are quite useful because there are many nails out there.
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:  In progress. My current focus is on wisdom traditions (Buddhism, Taoism, Christian Mysticism, Epicureanism, Socrates, Psychology of Evil, Counseling, Eckhart Tolle, Thomas Merton, etc).
