"Again. Self-culture is Intellectual. We cannot look into ourselves without discovering the intellectual principle, the power which thinks, reasons, and judges, the power of seeking and acquiring truth.... By education, men mean almost exclusively intellectual training. For this, schools and colleges are instituted, and to this the moral and religious discipline of the young is sacrificed. Now I reverence, as much as any man, the intellect; but let us never exalt it above the moral principle. With this it is most intimately connected. In this its culture is founded, and to exalt this is its highest aim. Whoever desires that his intellect may grow up to soundness, to healthy vigor, must begin with moral discipline. Reading and study are not enough to perfect the power of thought. One thing above all is needful, and that is, the disinterestedness which is the very soul of virtue. To gain truth, which is the great object of the understanding, I must seek it disinterestedly. Here is the first and grand condition of intellectual progress. I must choose to receive the truth, no matter how it bears on myself. I must follow it, no matter where it leads, what interests it opposes, to what persecution or loss it lays me open, from what party it severs me, or to what party it allies. Without this fairness of mind, which is only another phrase for disinterested love of truth, great native powers of understanding are perverted and lead astray ; genius runs wild ; " the light within us becomes darkness." The subtilest reasoners, for want of this, cheat themselves as well as others, and become entangled in the web of their own sophistry. It is a fact well known in the history of science and philosophy, that men, gifted by nature with singular intelligence, have broached the grossest errors, and even sought to undermine the grand primitive truths on which human virtue, dignity, and hope depend. And on the other hand, I have known instances of men of naturally moderate powers of mind, who by a disinterested love of truth and their fellow-creatures, have gradually risen to no small force and enlargement of thought. Some of the most useful teachers, in the pulpit and in schools, have owed their power of enlightening others, not so much to any natural superiority, as to the simplicity, impartiality, and disinterestedness of their minds, to their readiness to live and die for the truth. A man, who rises above himself, looks from an eminence on nature and providence, on society and life. Thought expands as by a natural elasticity, when the pressure of selfishness is removed. The moral and religious principles of the soul, generously cultivated, fertilize the intellect. Duty, faithfully performed, opens the mind to Truth, both being of one family, alike immutable, universal, and everlasting.
I have enlarged on this subject, because the connexion between moral and intellectual culture is often overlooked, and because the former is often sacrificed to the latter. The exaltation of talent, as it is called, above virtue and religion is the curse of the age. Education is now chiefly a stimulus to learning, and thus men acquire power without the principles which alone make it a good. Talent is worshipped ; but, if divorced from rectitude, it will prove more of a demon than a god."
