If modern reason cannot concern itself with the question of God, then it cannot argue that a God who commands jihad is better or worse than a God who commands us not to use violence to impose our religious views on others. To the modern atheist, both Gods are equally figments of the imagination, in which case it would be ludicrous to discuss their relative merits. The proponent of modern reason, therefore, could not possibly think of participating in a dialogue on whether Christianity or Islam is the more reasonable religion, since, for him, the very notion of a "reasonable religion" is a contradiction in terms."
"Modern science cannot tell us that the emperor is right in his controversy with the learned Persian over what is or is not contrary to God's nature. Modern reason proclaims such questions unanswerable by science--and it is right to do so. But can modern reason hope to survive as reason at all if it insists on reducing the domain of reasonable inquiry to the sphere of scientific inquiry? If modern reason cannot take the side of the emperor in this debate, if it cannot see that his religion is more reasonable than the religion of those who preach and practice jihad, if it cannot condemn as unreasonable a religion that forces atheists and unbelievers to make a choice between their intellectual integrity and death, then modern reason may be modern, but it has ceased to be reason."
"Modern reason says that all ethical choices are subjective and beyond the scope of reason. But if this is so, then a man who wishes to live in a community made up of reasonable men is simply making a personal subjective choice--a choice that is no more reasonable than the choice of the man who wishes to live in a community governed by brute force. But if the reasonable man is reasonable, he must recognize that modern reason itself can only survive in a community made up of other reasonable men. Since to be a reasonable man entails wishing to live in a community made up of other reasonable men, then the reasonable man cannot afford to allow the choice between reason and violence to be left up to mere personal taste or intellectual caprice. To do so would be a betrayal of reason."
I have already ordered this author's Civilization and Its Enemies from Amazon, just after reading this essay.
