Philosophical theories are theories that are philosophical, rather than purely scientific by nature. Meanwhile, philosophical concepts can be loosely describes as ideas or “concepts” that are philosophical in nature.

Generally, a concept is a single idea, a theory is an explanation of how something works, and philosophy is simply the study of that which we can’t know for sure (see the branches of philosophy.).

So then, for our purposes, philosophical theories and concepts is simply a broad category that contains all non-scientific theories worth discussing.

TIP: For a great explainer on the basics of Philosophy see Tamar Gendler: An Introduction to the Philosophy of Politics and Economics by Big Think.

NOTE: Some scientific theories that spark metaphysical philosophical questions are categorized here (as well as under their respective scientific fields). Learn more about scientific theories.
