What I mean by giving credence to propositions is pretty much the same as having “no doubt” about them. It is the sort of assent which we give to those opinions and professed facts which are ever presenting themselves to us without any effort of ours, and which we commonly take for granted, thereby obtaining a broad foundation of thought for ourselves, and a medium of intercourse between ourselves and others. This form of notional assent comprises a great variety of subject-matters; and is, as I have implied, of an otiose and passive character, accepting whatever comes to hand, from whatever quarter, warranted or not, so that it convey nothing on the face of it to its own disadvantage. From the time that we begin to observe, think, and reason, to the final failure of our powers, we are ever acquiring fresh and fresh informations by means of our senses, and still more from others and from books. The friends or strangers whom we fall in with in the course of the day, the conversations or discussions to which we are parties, the newspapers, the light reading of the season, our recreations, our rambles in the country, our foreign tours, all pour their contributions of intellectual matter into the storehouses of our memory; and, though much may be lost, much is retained. These informations, thus received with a spontaneous assent, constitute the furniture of the mind, and make the difference between its civilized condition and a state of nature. They are its education, as far as general knowledge can so be called; and, though education is discipline as well as learning, still, unless the mind implicitly welcomes the truths, real or ostensible, which these informations supply, it will gain neither formation nor a stimulus for its activity and progress. Besides, to believe frankly what it is told, is in the young an exercise of teachableness and humility.
