Alchemy is like an inductive Turing machine, to be programmed to learn broadly or restrictedly.
The logic formulas from rules through which it represents can be inconsistent, incomplete, or even incorrect-- the learning and probabilistic reasoning will correct them. The key point is that Alchemy doesn't have to learn from scratch, proving Wolpert and Macready's no free lunch theorem wrong by performing well on a variety of classes of problems, not just some.
