We explain a basic theory of human knowledge, in the style of Kant, to help illustrate some essentials of what we can know.
Logic is a branch of philosophy that deals with reasoning. Logic is used in mathematics, computing, philosophy, culture, and more. This section covers all formal and informal logic and all sub-sets of logic.
Reason and logic are two closely related forms of thinking involving the comparison of terms that can be studied in terms of mathematics or philosophy and can be considered together as well as apart.
All knowledge, all human understanding, can be said to be of four types: physical (empirical), logical (reason), ethical (philosophy in-action), and metaphysical (pure philosophy).
We explore the nature of truth, the different types of truth, and the different types of entities who report truth to better understand the nature of information.
Identifying a problem is often harder than solving it. Solving a problem requires a proper diagnosis, and that requires asking the right questions.
The major branches of philosophy are (roughly), metaphysics (what is), epistemology (what we can know), logic and reason, ethics and morality, and aesthetics (beauty and art).
