Sure, and bracketing the difference between a mathematically defined relation like a circle and a social practice like science, I'm wondering where the boundary between systematic knowledge and science lies. Blacksmiths, midwives, monks, farmers, warriors, stone masons, fisherfolk, cooks, and healers have all had systematic knowledge... are they Scientists now? Even though they are note defined that way under modernity?
^^^^^ CB: Yes, many of them are scientists, materialists. In _Les Pensees Sauvage_, Levi-Strauss illustrates the scientific knowledge, botany, of prehistoric peoples.
Here's a first epistemological principle: the test of theory is practice; the proof of the pudding is in the eating. The blacksmith demonstrates his metalugical scientific knowledge when the horseshoes function well. The stone masons who built Mexican or Egyptian pyramids proved their scientific and geometric knowledge in practice still evident to us today.
Science didn't begin in Europe in the 1400's.
