Contingency

Hieronymus Bosch - The Garden of Earthly Delights

The progress of scientific Analysis has revealed several perfectly objective profound effects that limit the power of scientific Analysis. I identify three such phenomena: projection (i.e., the fact that we don’t get to see everything), the probabilistic logic of quantum mechanics, and chaos (i.e., extreme sensitivity to initial conditions). These effects will make it impossible, in practice, to go from the solution (if we had it) of the basic equations (if we had them) to a complete description of the experience. The technical word for this is contingency – you can’t analyze everything, some things are just accidents … Thus reason discovers its own limitations.
