The second is more constant; as being “regulated” by some desire, and design. For the impression made by such things as we desire, or fear, is strong, and permanent, or, if it cease for a time, of quick return: so strong it is sometimes, as to hinder and break our sleep. From desire, ariseth the thought of some means we have seen produce the like of that which we aim at; and from the thought of that, the thought of means to that mean; and so continually, till we come to some beginning within our own power. And because the end, by the greatness of the impression, comes often to mind, in case our thoughts begin to wander, they are quickly again reduced into the way: which observed by one of the seven wise men, made him give men this precept, which is now worn out, Respice finem; that is to say, in all your actions, look often upon what you would have, as the thing that directs all your thoughts in the way to attain it.
