A way to justify Occam and Induction more explicitly is by appealing to natural selection. Take large groups of anti-inductor anti-occamians and occamian inductors, and put them in a partially-hostile environment. The Inductors will last much longer. Now, possibly the quality of maximizing inclusive fitness is somehow based on induction or Occam's Razor, but in a lawful universe it will usually be the case that the inductor wins.
