It was for a long time the custom to recommend knowledge to the attention of the people by depicting the material advantages and pleasures incident to its pursuit. Glowing and attractive pictures were exhibited of the career and progress of meritorious and successful persons, who had been elevated by their intelligence to positions of consideration and distinction. Universal history and biography were ransacked to furnish instances of a persevering and well-rewarded prosecution of knowledge 'under difficulties;' and the general mind was invited to contemplate and reflect on these, as worthy exemplars for its imitation. The inference, moreover, that was almost uniformly intended to be drawn, was such a one as was naturally acceptable to the crude and undisciplined understanding--the obvious purpose of all such representations being to stimulate the energies and enterprise of the ambitious, by the offer or indication of material rewards, and to make intelligence respected and desirable for the sake of its sensible compensations. There might perhaps be reasons adducible to justify the employment of such incitements, as there may doubtless be circumstances under which the cultivation of knowledge might, for a time, be more effectually advanced by means of interested considerations, than by an appeal to motives more strictly rational, and accordant with a disinterested reverence for its spiritual worth and dignity. There are evidently stages of human progress when a regard for their personal interests has a more powerful efficacy in urging men into improvement, than any of the finer influences of which they are susceptible, or which an advanced culture would probably awaken. Thus, as an exoteric or introductory intimation of the value and desirableness of knowledge, it may not be amiss to attract a people, otherwise indisposed to its acquirement, by an exhibition of the conventional advantages and distinctions which it may contribute, more or less successfully, to realise. And though it cannot be allowed that the culture of the intellect is to be subordinated to the acquisition of any of the temporal benefits of life, yet inasmuch as an increase of intelligence and sagacity may be reasonably applied to the promotion of such comforts and conveniencies as tend to enhance the rational satisfactions of existence, it is not to be questioned that the latter may be innocently, and even serviceably, urged upon the attention, as reasons and motives for stimulating the slothful or indifferent mind to an appropriate activity, whensoever higher and worthier considerations may have been found to be ineffectual, or are in any likelihood of being imperfectly apprehended. The sole condition needful
