Keep the Imagination under Control; sometimes correcting, sometimes assisting it. For it is all-important for our happiness, and even sets the reason right. It can tyrannise, and is not content with looking on, but influences and even often dominates life, causing it to be happy or burdensome according to the folly to which it leads. For it makes us either contented or discontented with ourselves. Before some it continually holds up the penalties of action, and becomes the mortifying lash of these fools. To others it promises happiness and adventure with blissfuldelusion. It can do all this unless the most prudent self-control keeps it in subjection.
