C.S. Lewis

I am reading a book by C.S. Lewis, and in my Xanga, I have made a previous entry, but it is down now, so I have moved here. The book I am reading is called Miracles. I am loving it. It shows from a metaphysical point of view why the Supernatural is necessary to allow for real reason. If we believe in Nature as being all there is, then we must also be a part of Nature. If we are only a part of Nature, and we seem to be noticing that all of Nature is governed by regular laws with Causes and Effects, then our thinking is also governed by Cause and Effect. If so, then we can explain why we think certain ways. We are thinking because some molecules have been set in motion, and our experience is simply a side effect of Nature's machine. This invalidates our logical thought. Basically then every thought is because of a Cause, instead of a Ground. Grounds are logical basis for Consequents in metaphysics. If an action has an external cause, then it is not because of Grounds A,A', and A'' that we conclude the consequent B, but rather because of some external event C (or events). In order for our reason to be real, there must be something outside of the machine called Nature that causes thoughts, and allows us to conclude B given A, despite some external influence C.
