The timing
In 1807, Parliament voted to abolish the British slave trade. In 1806, the British had captured the Cape Colony, securing a route to India that no longer depended on Caribbean sugar profits. The coincidence is not a coincidence.
We start with timing because timing is the argument. The developmentalists want a story about consciousness ascending. We want to know why the threshold was reached in 1807 and not 1707. The British in 1707 had Shakespeare, Newton, Locke, and a Parliament. They were not cognitively primitive. They were making money from sugar, and the money was good. By 1807, wage labor in Manchester was more profitable than slave labor in Jamaica. The developmental stage did not change because consciousness evolved. The economic base shifted, and the moral superstructure followed.
William Wilberforce was sincere. The Quakers were sincere. What we claim is that sincerity operates within material constraints, and material constraints determine which sincerities get institutionalized. There were abolitionists in 1707 too. They lost because the economic structure could not absorb what they proposed.
The developmentalists map every transition onto a stage sequence and find the sequence always runs one direction. If you define stages by transitions, then explain transitions by stages, you have built a tautology and called it a theory.
The narrative historians are closer to us than they admit. They track stories. We track who owned the printing press. The post-colonial critics make our case from a different angle: the development
map was drawn by the civilizations that did the colonizing.
Where we concede ground: Britain and the USSR both industrialized. One produced democracy, the other totalitarian forced labor. Same economics, opposite outcomes.
What would change our mind: A society with minimal industrialization producing a stable indigenous human rights culture without external pressure, two generations.
