Martin Luther on Philosophy

"so it is with human reason, which strives not against faith, when enlightened, but rather furthers and advances it."

"Let all the 'free-will' in the world do all it can with all its strength; it will never give rise to a single instance of ability to avoid being hardened if God does not give the Spirit, or of meriting mercy if it is left to its own strength."

"Unless I am convinced by the testimony of the Scriptures or by clear reason , I am bound by the Scriptures I have quoted and my conscience is captive to the Word of God. I cannot and will not recant anything, since it is neither safe nor right to go against conscience. May God help me. Amen."

It seems an iniquitous, cruel, intolerable thought to think of God; and it is this that has been such a stumbling block to so many great men down through the ages. And who would not stumble at it? I have stumbled at it myself more than once, down to the deepest pit of despair, so that I wished I had never been made a man.
