of our infancy and childhood, our senses were joint friends with the passions in such a way that whatever delighted sense pleased the passions, and whatever was harmful to the one was an enemy to the other; and so, by long agreement and familiarity, the passions had so engaged themselves to sense, and confirmed their friendship with such bonds and seals of sensual habits, that as soon as reason came into possession of her kingdom, they immediately began to rebel. For right reason often deprived sense of those pleasures he had long enjoyed, as by commanding continence and fasting, which sense most abhorred; then the passions resisted, and very often hauled her by force to yield to what they demanded, which combat and captivity were well perceived by him who said,
