Philosophy is a system of reasoning that is applied to Theology. Self correcting in that with more study and deeper reasoning prior mistakes get corrected. Like relativity correcting Newtonian laws. Einstein did that theoretically, with thought experiments. Lotsa new data. For example the considerations implied by the expanding universe (Lematre). You would say nothing new since Aristotle's day?
The key elements in human thinking are not numbers but labels of fuzzy sets. -- L. Zadeh
