Morals excite passions, and produce or prevent actions. Reason of itself is utterly impotent in this particular. The rules of morality, therefore, are not conclusions of our reason. David Hume
Pagan philosophers set up reason as the sole guide of life, of wisdom and conduct; but Christian philosophy demands of us that we surrender our reason to the Holy Spirit; and this means that we no longer live for ourselves, but that Christ lives and reigns within us. John Calvin
We are all human, and our senses are quicker to prompt us than our reason. Every man gives off a scent, and that scent tells you how to act before your head does. Aleksandr Solzhenitsyn
We are not here concerned with hopes or fears, only with truth as far as our reason permits us to discover it. Charles Darwin
The rules of morality are not the conclusion of our reason. David Hume
Our passions are the winds that propel our vessel. Our reason is the pilot that steers her. Without winds the vessel would not move and without a pilot she would be lost. Traditional Proverb
