From Self-Help (1859) by Samuel Smiles:

It is possible that at this day we may even exaggerate the importance of literary culture. We are apt to imagine that because we possess many libraries, institutes, and museums, we are making great progress. But such facilities may as often be a hindrance as a help to individual self-culture of the highest kind. The possession of a library, or the free use of it, no more constitutes learning, than the possession of wealth constitutes generosity. Though we undoubtedly possess great facilities it is nevertheless true, as of old, that wisdom and understanding can only become the possession of individual men by travelling the old road of observation, attention, perseverance, and industry. The possession of the mere materials of knowledge is something very different from wisdom and understanding, which are reached through a higher kind of discipline than that of reading, — which is often but a mere passive reception of other men’s thoughts; there being little or no active effort of mind in the transaction. Then how much of our reading is but the indulgence of a sort of intellectual dram-drinking, imparting a grateful excitement for the moment, without the slightest effect in improving and enriching the mind or building up the character. Thus many indulge themselves in the conceit that they are cultivating their minds, when they are only employed in the humbler occupation of killing time, of which perhaps the best that can be said is that it keeps them from doing worse things.

It is also to be borne in mind that the experience gathered from books, though often valuable, is but of the nature of learning; whereas the experience gained from actual life is of the nature of wisdom; and a small store of the latter is worth vastly more than any stock of the former. Lord Bolingbroke truly said that “Whatever study tends neither directly nor indirectly to make us better men and citizens, is at best but a specious and ingenious sort of idleness, and the knowledge we acquire by it, only a creditable kind of ignorance — nothing more.”
