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.

Conway’s Game of Life Models Evolution


The Game of Life - a cellular automaton

Conway’s Game of Life is a simple rule-set that models the evolution of systems. It’s a “zero-player” computer program that demonstrates “cellular automata”.

All Types of Systems are Generally Comparable


All Systems are Generally Analogous

General systems theory shows us there are commonalities between different types of physical and conceptual systems which we can study to better understand complex systems.

Everything Depends on Frame of Reference


Everything we perceive depends on our frame of reference. What we observe is relative to our point of view. In other words, “it is all a matter of perspective”.

Being Equal Means Having Equivalent Value


Being Equal Means Having Equivalent Value

The term ‘equal’ can mean ‘identical’, but more-so it describes “equivalence.” For example, social equality describes equity, not “exact the sameness.”

People Can be Truly Unbiased


Can People Truly be Unbiased?

People can’t be truly unbiased; we are hardwired with bias and create bias constantly as part of the natural neurological process of learning.

Bayes’ Theorem Can Calculate Probable Truth


Bayes' theorem

Bayes’ theorem is a probability theory used to calculate the likelihood of an event being true or not true based on conditions related to the event. (i.e. an equation used for calculating conditional probabilities).

We Learn Best by Being Taught


Do We Learn Best by Being Taught?

The best way to learn isn’t “being taught”, its mixing self-directed learning with the roles of student, peer, and teacher in different social settings.

Humans are Hardwired to be Social Beings


Are Humans Hardwired to be Social Beings?

Humans are hardwired to be social beings. We naturally cooperate, care, and compete. From quarks, to cells, to plants, to animals, cooperation is in our DNA.
