William james version of the wager pragmatism: truth = the useful for most beliefs, evidence matters for some, there is no evidential grip the provide a (vital benefit) they are low cost evidentially. It is wrong to believe with out evidence because we will stop trying to test things and we will loose our ability to try and prove things, and thus go back into a state of savagery. If god is omniscient, he knows there is evil. If god is omni-potent he can eliminate what he abhors. Therefore there is no evil if god exists. But there is too much soul improving evil. People are free beings and sometimes do evil. Natural evil are evils that are not the result of the free will of any agent. What is the difference between knowledge and belief. When (if x then y) is true the y is a necessary condition for x. Altering either belief or desire alters the action.
