Reason Without Faith

This is an interesting take on Reason.
The Big Apple Coalition on Reason

"Yet while our collective viewpoint is secular, we share commonalities with many belief systems -- including religious. We are committed to a more compassionate world; we are working for a more reasonable citizenry and a higher level of discourse; we are striving to increase the quality of life for all; and we find fellowship an integral part of the human condition. Theists and nontheists alike are the same people: we go to work everyday; we have families and friends; we are involved in our communities, state, and country; and we care deeply about life."

Here is what Pope John Paul II said in Fides et Ratio :

Deprived of what Revelation offers, reason has taken side-tracks which expose it to the danger of losing sight of its final goal. Deprived of reason, faith has stressed feeling and experience, and so run the risk of no longer being a universal proposition. It is an illusion to think that faith, tied to weak reasoning, might be more penetrating; on the contrary, faith then runs the grave risk of withering into myth or superstition. By the same token, reason which is unrelated to an adult faith is not prompted to turn its gaze to the newness and radicality of being.

This is why I make this strong and insistent appeal—not, I trust, untimely—that faith and philosophy recover the profound unity which allows them to stand in harmony with their nature without compromising their mutual autonomy. The parrhesia of faith must be matched by the boldness of reason.
