The three most fundamental sources of knowledge are physics, math, and human history. They offer us endless learning and mental models.

Physics and math, from which we derive the rules the universe plays by; biology, from which we derive the rules life on Earth plays by; and human history, from which we derive the rules humans have played by.

History is subject to geology.

To the geologic eye all the surface of the earth is a fluid form, and man moves upon it

History repeats itself in the large because human nature changes with geological leisureliness, and man is equipped to respond in stereotyped ways to frequently occurring situations and stimuli like hunger, danger, and sex.

Most importantly, fragile relationships break, but strong win-win relationships have super glue that keeps parties together.

that a lack of adaptiveness to changing reality is a losing strategy when the surrounding environment shifts enough.

Our various systems of political and economic organization are fundamentally driven by decisions on how to give order and fairness to the brutal reality created by human competition.

Life is Competition. Life is Selection. Life must Replicate.

Knowledge — the kind which can be passed from generation to generation in an accumulative way — is a unique outcome in the human culture bucket. Other biological creatures only pass down DNA, not accumulated learning.
