There are no fundamental changes across history in the laws governing the economic and scientific evolutions of civilizations. The same drive and intellectual talent was needed to discover the mathematic rules of the planetary movements in -XVIIIth-century Babylon as to find the laws of electromagnetism in XIXth century Britain. Developping its business requires the same kind of talent and impulse for an entrepreneur, for a maritime investor in Sumer in IIIrd millenium b.c. as for a venture capitalist today. The are no deep qualitative transition between "primitive economy" and "capitalism", just a quantitative one. The same laws of evolution govern the evolution of societies at all stages.
