A note that captures exactly one idea can be understood without its original context, linked to any argument, and recombined indefinitely — a note that captures two ideas can do none of these things reliably.
You do not understand something until you can decompose it — and the act of decomposition will show you exactly where your understanding breaks down.
The smallest useful unit is the level of decomposition where each piece carries independent meaning — small enough to be precise, large enough to be self-contained.
An idea that looks like one thing is often several things fused together, each carrying unstated assumptions that silently constrain what you can do with it.
You choose how finely to decompose based on your purpose — not on some inherent "correct" level of detail. The same material supports different grain sizes for different uses.
The definitions you use quietly shape every conclusion built on top of them.
The goal is not perfect decomposition but steadily improving your ability to decompose.
