Surplus
The Economic Aspect
the Neolithic — the present
What conditions let a clever trick become a permanent technology?
A tool invented and forgotten is not yet technology; it becomes technology when a society can afford to keep, teach, and improve it. Surplus, specialization, and exchange are the soil in which inventions take root — which is why the Neolithic settling-down, not any single device, is the true origin of cumulative technology.
01Man makes himself
The archaeologist V. Gordon Childe named the 'Neolithic Revolution' and the 'Urban Revolution': farming produced storable surplus, surplus freed some hands from food, freed hands became potters, smiths, scribes, priests. Specialization is a technology for making technologies — and the city is the machine that concentrates enough minds and materials for invention to compound.
02Why writing was born in a warehouse
The earliest writing, Mesopotamian cuneiform, did not begin as poetry but as accounting — tallies of grain, sheep, and beer owed to the temple. Number and the written sign were born from the bookkeeping of surplus. Marx put the general case sharply: a society's tools and its social relations shape each other, so technology's origins are never purely technical. They are also about who stores the grain, and who counts it.
“Invention is cheap; keeping is dear. Technology accumulates only where a society can pay to remember.”
In short
- Storable surplus from farming freed specialists who could refine tools.
- Childe: the city is the engine that compounds invention.
- Writing began as accounting for grain, not as literature.
