An Illustrated Brief History of Western Philosophy, ch. 21

This chapter looks at logic and the foundation of mathematics. Frege offered what he believed to be a pure form of logic. Russel, who is also a logician, obliterated Frege's pure logic. Though the logic is still helpful, it is altogether defeated by Russel. Russel was an outspoken atheist and, when considering his analysis style, you can see how he would at least arrive at agnosticism. He is an important thinker and must be dealt with to philosophically hold a view of God.
