That evening I lit many candles and sat in the library wearing fresh linen and drinking good wine while I read a treatise on astronomy by a student of Kepler's and reflected on my increasing disagreement with Luther, who had judged reason to be the chief enemy of Faith, of the purity of his beliefs. He had considered reason a harlot, willing to turn to anyone's needs, but this merely displayed his own suspicion of logic. I have come to believe him the madman Catholics described him as. Most mad people see logic as a threat to the dream in which they would rather live, a threat to their attempts to make the dream reality (usually through force, through threat, through manipulation and through bloodshed). It is why men of reason are so often the first to be killed or exiled by tyrants.
