Knowledge is probabilistic

Knowledge itself is probabilistic in nature, a notion emphasized by some currents of philosophical pragmatism.

We are certain of nothing because as our knowledge changes we can reinterpret the facts of the past. History is alive because knowledge is probabilistic. Economics is alive because our views are adapting with new theories. The Great Depression is being reinterpreted because our knowledge of economics is adapting.
