First Principles
A cook follows a recipe. A chef understands ingredients. First
Principles Thinking is the act of stripping away assumptions
until you reach irreducible truths.
01/Definition
Root Thought
= First Principles: The first basis from which
a thing is known.
= Deconstructing a problem into fundamental
parts and rebuilding from scratch.
02/The Contrast

ANALOGY
-
"X is like Y, so do what Y
did."
-
Inherits historical
baggage.
-
Fast, but limited by what
already exists.

"What are the irreducible
components?"

Builds from fundamental
truths.

Slow, but allows for
revolutionary solutions.
03/CLN: The First Principles Syntax
CLN forces this mindset through its very structure:
= Definitions: Force you to
say what something IS, not what it is "like."
? Questions: Expose exactly
where you are relying on an unproven assumption.
! Constraints: Define the hard
physical or logical boundaries.

Discover
* Don't look at what others did. Write a CLN
block.
* Define the truths, list the constraints, and
see what remains possible.
= The
notation is the path from assumption to truth.
