The Problem of Induction Although James and Clifford disagree about the reasonableness of belief in a special class of propositions(when they constitute a genuine choice for us), they agree that in the majority of cases empirical investigation and the scientific pursuit of evidence is at least a, if not the proper way to proceed in forming beliefs. It

1. The\Wager\and the Practical Rationality Principle Practical Rationality Principle: The practically rational thing to do is the thing with the highest expected value(or utility \) Version A: Do the thing with higher expected value than all its competitors --In the case of a tie, neither action/belief is permitted Version B: Find the actions with highest expected value and perform whichever of them you like --In the case of a tie, Theism is practically rational. Just like choosing pie over cake 2. Evidentialism(Clifford)

What is Online Learning? In an online lesson, the computer displays material in response to a learner's request. The computer promotes the learner for more information and presents appropriate material based on the learners response. The material can be traditional lessons and tests that are transcribed into a computer program. The material can also be a complex program that tracks users'input and
