This circumstance in the structure of the human understanding is well known, and is the foundation of many provisions that occur in the constitution of political society. How each man shall form his creed, and arrange those opinions by which his conduct shall be regulated, is of course a matter exclusively subjected to his own discretion. But, when he is called upon to act in the name of a community, and to decide upon a question in which the public is interested, he of necessity feels himself called upon to proceed with the utmost caution. A judge on the bench, a chancellor, is not contented with that sudden ray of mental illumination to which an ingenuous individual is often disposed to yield in an affair of abstract speculation. He feels that he is obliged to wait for evidence, the nature of which he does not yet anticipate, and to adjourn his decision. A deliberative council or assembly is aware of the necessity of examining a question again and again. It is upon this principle that the two houses of the English parliament are required to give a first, a second and a third reading, together with various other forms and technicalities, to the provision that is brought before them, previously to its passing into a law. And there is many a fundamental dogma and corner-stone of the sentiments that I shall emphatically call my own, that is of more genuine importance to the individual, than to a nation is a number of those regulations, which by courtesy we call acts of parliament. Nothing can have a more glaring tendency to subvert the authority of my opinion among my fellow-men, than instability. "What went ye out into the wilderness to see" said Jesus Christ: "a reed shaken with the wind?" We ought at all times to be open to conviction. We ought to be ever ready to listen to evidence. But, conscious of our human frailty, it is seldom that we ought immediately to subscribe to the propositions, however specious, that are now for the first time presented to us. It is our duty to lay up in our memory the suggestions offered upon any momentous question, and not to suffer them to lose their inherent weight and impressiveness; but it is only through the medium of consideration and reconsideration, that they can become entitled to our full and unreserved assent.
