Bulversim

After reading through the essay Bulversim a few times, I was still looking for something to write about then it hit me. In the first section about the Marxist and Freudians arguments for their worldview. Lewis points out that the same argument that they make can be turned around and used against them. First Lewis clams that either every thought is tainted at the source or it is possible that only some are tainted. Since the latter is given in his next proof, Lewis then goes into his next point that, since there is no way to good way of telling which thoughts our tainted and which ones are not then, the Marxist and Freudians worldviews are just as valid and any other idea. One mistake in Marxist and Freudian arguments that Lewis makes a theme of later in the essay is the idea of Bulversim. Lewis states that because people already have a viewpoint about a certain topic it, when faced with evidence that contradicts their beliefs. People automatically discredit evidence without reason or just one the basis of not aligning with their viewpoint. As a person that loves to debate with others. I have seen this many times but never identified this phenomenon of Bulversim nearly as clearly as Lewis has.   The way I see the issue of Bulversim is that it needs to be cut out from arguments  and peoples lives because in any argument it is an easy way out of critically thinking about our own beliefs.
