Begin with the assumption that everything you know about software is wrong. Every framework, every pattern, every "best practice" -- subject them to radical doubt. What survives the fire of skepticism is the only material worth building upon.
The Cartesian method demands we disassemble our certainties. Not in anger or cynicism, but with the quiet precision of a geometer who discovers an axiom may be a mere convention. What if the foundations are dreaming?
Here, at coordinates we cannot yet trust, we plot the first uncertain points. The grid beneath our feet may warp. The shadows our constructs cast may not correspond to their true forms. This is the starting condition: productive doubt.
In the depths of doubt, one certainty survives: the act of thinking itself. If I doubt, I think. If I think, I exist. This irreducible fact is the foundation upon which everything else can be rebuilt.
Software, too, has its cogito -- the moment when abstraction meets execution, when the idea becomes the running process. Not the specification, not the documentation, but the living computation. I compute, therefore I am.
From this single fixed point, we can begin to plot new coordinates with confidence. The grid stabilizes. The shadows begin to align. What was uncertain becomes the substrate for construction.
Decompose until irreducible. Each component must justify its own existence -- no inherited assumptions, no cargo-cult patterns. Build only from what you have proven to yourself.
Divide each difficulty into as many parts as possible. Solve each part separately. Then compose the solution from these verified fragments. The order of assembly matters.
Make enumerations so complete, and reviews so general, that nothing is omitted. Every edge case catalogued. Every state transition mapped. Exhaustive verification.
Begin with the simplest objects and ascend step by step to the most complex. Dependencies must flow in one direction. The architecture is the argument.
An idea is clear when it is present and apparent to an attentive mind. Clean interfaces. Transparent state management. Code that reveals its intention without commentary.
An idea is distinct when it is so precise that it contains nothing which is not clear. Separation of concerns elevated to epistemological principle. Each module a universe unto itself.
