In conversing with books we may choose our company, and disengage without ceremony or exception. Here we are free from the formalities of custom and respect: we need not undergo the penance of a dull story from a fop of figure; but may shake off the haughty, the impertinent, and the vain, at pleasure. Besides, authors, like women, commonly dress when they make a visit. Respect to themselves makes them polish their thoughts, and exert the force of their understanding more than they would or can do in ordinary conversation: so that the reader has as it were the spirit and essence in a narrow compass; which was drawn off from a much larger proportion of time, labour, and expense. Like an heir, he is born rather than made rich; and comes into a stock of sense, with little or no trouble of his own. 'Tis true, a fortune in knowledge which descends in this manner, as well as an inherited estate, is too often neglected and squandered away; because we do not consider the difficulty in raising it. Books are a guide in youth, and an entertainment for age. They support us under solitude, and keep us from being a burthen to ourselves. They help us to forget the crossness of men and things; compose our cares and our passions; and lay our disappointments asleep. When we are weary of the living, we may repair to the dead, who have nothing of peevishness, pride, or design in their conversation. However, to be constantly in the wheel has neither pleasure nor improvement in it. A man may as well expect to grow stronger by always eating, as wiser by always reading. Too much overcharges Nature, and turns more into disease than nourishment. 'Tis thought and digestion which makes books serviceable, and gives health and vigour to the mind. Neither ought we to be too implicit or resigning to authorities, but to examine before we assent, and preserve our reason in its just liberties. To walk always upon crutches is the way to lose the use of our limbs. Such an absolute submission keeps us in a perpetual minority, breaks the spirits of the understanding, and lays us open to imposture.
