As we brew, we must bake

Invisible things are the only realities; invisible things alone are the things that shall remain.

Truth is powerful, and, if not instantly, at least by slow degrees, may make good her possession. Gleams of good sense may penetrate through the thickest clouds of error. But we are supposing in the present case that truth is the object of the preceptor. Upon that assumption it would be strange indeed, if he were not able to triumph over corruption and sophistry, with the advantage of being continually at hand, of watching every change and symptom as they may arise, and more especially with the advantage of real voice, of accommodated eloquence, and of living sympathies, over a dead letter. These advantages are sufficient; and, as the true object of education is not to render the pupil the mere copy of his preceptor, it is rather to be rejoiced in, than lamented, that various reading should lead him into new trains of thinking; open to him new mines of science and new incentives to virtue; and perhaps, by a blended and compound effect, produce in him an improvement which was out of the limits of his lessons, and raise him to heights the preceptor never knew.
