“Neither reason nor faith will ever die; for men would die if deprived of either. The wildest mystic uses his reason at some stage; if it be only by reasoning against reason. The most incisive sceptic has dogmas of his own; though when he is a very incisive sceptic, he has often forgotten what they are. Faith and reason are in this sense co-eternal; but as the words are popularly used, as loose labels for particular periods, the one is now almost as remote as the other. What was called the Age of Reason has vanished as completely as what are called the Ages of Faith.”

Context: There is neither advance nor service without faith. Nobody can rationally explain why he should sacrifice his life and his happiness for the sake of the good. The conviction that I must obey the ethical imperatives is not derived from logical argument but originates from an intuitive certitude, in a certitude of faith.
There is no conspiracy against reason, no random obstinacy, no sluggish inertia of mind or smug self-assurance entrenched behind the walls of believing. Faith does not detach a man from thinking, it does not suspend reason. It is opposed not to knowledge but to backwardness and dullness, to indifferent aloofness to the essence of living. … It is a distortion to regard reason and faith as alternatives. Reason is a necessary coefficient of faith. Faith without explication by reason is mute, reason without faith is deaf. There can be a true symbiosis of reason and faith.
