Religious Emotions & Religious Logic

I'm reading the biography of Jonathan Edwards by George Marsden (Marsden is a professor of Church History at Notre Dame). One of the most interesting things in the book so far is the amount of emotion (religious emotion) that Edwards experienced. Everyone knows that he was a very good thinker, in fact, he might be a top-five theologian. I think the top four are pretty cemented regardless of what order you put them in, but for purposes here I list them in chronological order: St. Augustine, Thomas Aquinas, Martin Luther, and John Calvin. Now the fifth is either Jonathan Edwards, Freidrich Schliermacher, or Karl Barth (Roman Catholics might even consider John Henry Newman). Regardless, in many ways Edwards was similar to a contemporary evangelical, but in other ways he was far from one. The amount of intellectual rigor that Edwards put into his everyday life and his theology is far greater than any pastor I've ever met - but the most interesting thing is that his dad was intellectually rigorous, as were the other pastors of his day. In other words, Edwards might have worked harder and been more of an ascetic than the typical pastor of his time, but by no means was Edwards a freak compared to the other pastors. In our time he would be a freak, because he takes intellectual faith seriously. The thing that has been made clear to me from reading Edward's biography is that intellectual rigor and emotional faith are compatible.
