It may be objected that the Bible has been the fruitful source of contention and war; and some may suppose it cannot therefore be a standard of union to the world; but it should be remembered that, when it has become a cause of dissension, it has been by the perversion of man, who has separated doctrine from life,—has put asunder that which God joined. No contention has ever risen in the world regarding religious life, but many and terrible ones regarding religious doctrine separated from life; and it is perfectly apparent, that, had those who were engaged in them, looked to religious life with the same earnestness they did toward doctrine, all these dissensions must have ceased. Christian life is, as it were, a building, of which faith is the foundation. The foundation is subservient to the superstructure, and should be strong and well laid; but has no value excepting as it is the support of a worthy building. The Lord is very explicit in all his teachings on the subject of life, and it is hardly possible that any one could faithfully study his words, and then exalt abstract doctrine into the place that belongs of right to Christian life.

Whoever studies the direct teachings of the Lord, recorded by the Evangelists, and makes them the rules of his Thoughts, must necessarily be wise. Everything connected with daily life, if his mind be really permeated with these teachings, takes its proper place before him. He sees what has a transient, and what a permanent value,—what is merely temporal, and what eternal; and so learns to appreciate the relative value of all things. Everything that occurs becomes a subject for his thoughts to work upon, and while working in heavenly light his mind grows in wisdom day by day. This action of Thought will not be confined to events as they occur around him, but whatever is read, all the events of the past, all art and science, are brought under the same analysis. The thoughtless person reads merely for the amusement of the moment, remembers little of what he reads, and that little to no purpose. A fact is, to such a man, a mere fact standing by itself, and having no relation to anything else. However much he may read, the thoughtless man can never be instructed. He is of those who, seeing, perceive not, and who, hearing, do not understand. The thoughtful person, on the contrary, reads everything with a purpose. His mind works upon what he reads, and he is instructed and made intelligent, even though he may see only with the light of this world. His intelligence will, however, be very different and very inferior in degree to that of the man who looks at objects in the light of heaven. He will measure things by an uncertain, varying standard, and will appreciate things only according to their temporal value. He will, therefore, never become truly wise. With those whose minds are nurtured by the words of the Lord, everything is judged by the standard of eternal truth. Whatever is learned is digested by the thoughts, and so the powers of the mind are strengthened and enlarged. Thus the mind becomes constantly more and more wise. The merely intellectual man has the desire to become wise, but his eye is not single, and therefore his mind is obscured by many clouds,—the dark exhalations of worldliness. When a man fixes his eye upon the Lord he is filled with light, and sees with a clearness of vision such as can be gained from no other source.

The cultivation of Thought lies at the root of all intellectuality, while it elevates and enlarges the sphere of the Affections. Affection is above Thought, but it is sustained and invigorated by its influence. Thought being the foundation upon which Affection is built, the strength, permanence and reliability of Affection must depend on the solidity and justice of the underlying Thought.

The mind may be stored with the most varied and extensive knowledge, and yet be neither improved nor adorned thereby. Robert Hall once remarked of an acquaintance, that he had piled such an amount of learning upon his brain, it could not move under the weight. It is little matter whether the amount of learning be large or small; the brain is only encumbered by it, unless it has taken it into its own texture, and made it by Thought a part of itself. Some persons love facts as a miser loves gold, merely because they are possessions; but without any desire to make use of them. A fact or thought is just as valuable in itself as a piece of money. Gold and silver are neither food, nor raiment, nor shelter; but we value them because through their means we can obtain all these. So facts and thoughts are neither rationality, nor wisdom, nor virtue, and their value lies in their being mediums whereby we may obtain them all.

Undigested learning is as useless and oppressive as undigested food; and as in the dyspeptic patient the appetite for food often grows with the inability to digest it, so in the unthinking patient an overweening desire to know often accompanies the inability to know to any purpose. Thought is to the brain what gastric juice is to the stomach,—a solvent to reduce whatever is received to a condition in which all that is wholesome and nutritive may be appropriated, and that alone. To learn merely for the sake of learning, is like eating merely for the taste of the food. The mind will wax fat and unwieldy, like the body of the gormand. The stomach is to the frame what memory is to the mind; and it is as unwise to cultivate the memory at the expense of the mind, as it would be to enlarge the capacity of the stomach by eating more food than the wants of the frame require, or food of a quality that it could not appropriate. To learn in order to become wise makes the mind active and powerful, like the body of one who is temperate and judicious in meat and drink. Learning is healthfully digested by the mind when it reflects upon what is learned, classifies and arranges facts and circumstances, considers the relations of one to another, and places what is taken into the mind at different times in relation to the same subjects under their appropriate heads, so that the various stores are not heterogeneously piled up, but laid away in order, and may be referred to with ease when wanted. If a person's daily employments are such as demand a constant exercise of the thoughts, all the leisure should not be devoted to reading, but a part reserved for reflecting upon and arranging in the mind what is read. The manner of reading is much more important than the quantity. To hurry through many books, retaining only a confused knowledge of their contents, is but a poor exercise of the brain; it is far better to read with care a few well-selected volumes.

There is a strong tendency towards superficial culture at the present day, which is the natural result of the immense amount of books and periodicals constantly pouring from the press, and tempting readers to dip a little into almost everything, and to study nothing. Much is said of the pernicious consequences arising from lectures and periodicals, as though a short account of anything must of necessity be a superficial one; but this is far from the truth. A quarto volume on one theme may be entirely superficial, while a lecture or review-article on the same theme may contain the whole gist of the matter. Prolixity is oftener superficial than brevity. Books are superficial if they relate only to the outside of a subject,—if they describe only its husk; and the reverse, if they give its kernel. Many an able review-article contains the kernel of a whole volume, and if the pleased reader of the review goes to the book itself, expecting to enjoy that in a degree proportionate to its size, he will often find he has got nothing but a dry husk for his pains.

Those who have little time for books, but who wish really to know many things, can accomplish a great deal by being careful to hunt for meats rather than for shells and husks; for though the outsides of things make a great show, and can be displayed by the pedant to great advantage before those who are superficial as himself, they contain no healthful nutriment for the mind. Take, for instance, the study of botany. Let a person master the whole vocabulary of the science, and know the arrangement of its classifications so well that he can turn at once to the description of any plant he may find. Let him do this until, like King Solomon, he knows every plant by name, from the "hyssop on the wall to the cedar of Lebanon"; but if at the same time he knows nothing more about them than the name, his knowledge of botany is entirely superficial, though he may have spent a vast deal of time and labor in its acquisition. Let another person have studied the physiology of plants till he has learned all that has yet been discovered of their curious and beautiful structure,—till he appreciates as far as mortals may the Divine wisdom, that even in the formation of a blade of grass transcends not only all that man with all his pride of science and mechanical skill can perform, but goes far—we cannot even guess how far—beyond all that human intellect can comprehend; and still more if the mind of this student be lifted upward in adoration as he learns, he is the true botanist, though he may have studied far less, if we count by time, than his superficial brother.

So it is with all the sciences. The kernel is what nourishes the mind,—the knowledge of what God has created, and not the mere power of repeating the classifications and vocabularies that man has invented to describe these creations: not that these also have not an eminent use; but still it is one that should always be esteemed secondary in all our studies.

So, too, it is with history. One may have all the important dates, names, and facts of the world's history at the tongue's end, and yet be none the wiser; for such knowledge is but the surface of history. To know history well, is to have so arranged its facts in the mind that it may be contemplated as a continuous exhibition of God's providence. It is to study the succession of events, not as separate units, but as links of one vast chain, on every one of which is inscribed a phrase discoursing of the progress of the human race, and showing the growth of man in the complex, from infancy to adolescence. Further than that, we can hardly venture to believe the race has yet advanced. Thus studied, history is the noblest of all sciences, since it treats of the highest of God's creations; but studied as a mere congeries of facts, all sciences are alike worthless; and from the mousings of the mere antiquarian to the dredgings of the student of the shelly coverings of the Mollusca, all end in naught.

When a person's employment is one that does not require a constant exercise of the thoughts, there is the greater need of a constant supply of nutritious food for the mind, that it may be growing all the time by reflection, and thus be saved from falling into a morbid state, such as too often results from long confinement to an occupation demanding little exertion of its powers. The farmer at his plough, the mechanic at his bench, the seamstress at her needle, and a host of others, too often suffer the thoughts to wander into realms of morbid egotism and discontent, when, if they would turn them upon moral or intellectual themes, they might be growing wiser and better every day.
