§ XXVI. Therefore, with respect to knowledge, we are to reason and act exactly as with respect to food. We no more live to know, than we live to eat. We live to contemplate, enjoy, act, adore; and we may know all that is to be known in this world, and what Satan knows in the other, without being able to do any of these. We are to ask, therefore, first, is the knowledge we would have fit food for us, good and simple, not artificial and decorated? and secondly, how much of it will enable us best for our work; and will leave our hearts light, and our eyes clear? For no more than that is to be eaten without the old Eve-sin. § XXVII. Observe, also, the difference between tasting knowledge, and hoarding it. In this respect it is also like food; since, in some measure, the knowledge of all men is laid up in granaries, for future use; much of it is at any given moment dormant, not fed upon or enjoyed, but in store. And by all it is to be remembered, that knowledge in this form may be kept without air till it rots, or in such unthreshed disorder that it is of no use; and that, however good or orderly, it is still only in being tasted that it becomes of use; and that men may easily starve in their own granaries, men of science, perhaps, most of all, for they are likely to seek accumulation of their store, rather than nourishment from it. Yet let it not be thought that I would undervalue them. The good and great among them are like Joseph, to whom all nations sought to buy corn; or like the sower going forth to sow beside all waters, sending forth thither the feet of the ox and the ass: only let us remember that this is not all men's work. We are not intended to be all keepers of granaries, nor all to be measured by the filling of a storehouse; but many, nay, most of us, are to receive day by day our daily bread, and shall be as well nourished and as fit for our labor, and often, also, fit for nobler and more divine labor, in feeding from the barrel of meal that does not waste, and from the cruse of oil that does not fail, than if our barns were filled with plenty, and our presses bursting out with new wine.
