"But it would seem important to the continued success of this system, that its several parts should still be kept distinct and subordinate. I will not say that they may not subsist harmoniously, and be conducted usefully upon the same ground. I will not say that an university, sectional or national, that shall, in its separate colleges and halls, prepare our youth for the various departments of life, may not consist with the spirit of our civil governments, and be guarded against the evils which have generally attended establishments so complicate, and of such numerous resort. However this may be judged, it will be found, I apprehend, the wisdom of our scattered institutions, to preserve their individuality, and remain true, as to their general regulations, to the purpose of their foundation. With respect, particularly, to the arrangements of a college, it would seem not less true than in regard to the efforts of an individual mind, or the operations of a machine, that however numerous and various these arrangements may be in detail, the most beneficial results cannot be expected without unity of design. Between that kind of cultivation and discipline necessary as a foundation for professional eminence, and that which is required for success in mercantile, mechanical, or agricultural occupation, there is a very natural and obvious distinction. And not only is it desirable that they who will be successful mainly as they shall be conversant with books, who require to be learned men, and they whose concern lies principally in the active business of life, in skill or labor, should have in some respects a different course of study, but be subjected to the influence of different minds, and examples, and rules, and scenes, and associations, corresponding to the different relations which they will sustain. 'Non omnia possumus omnes,' is a proverb applicable both to teachers and to pupils, and it would forbid the supposition, that minds which act upon others for widely different purposes, should do it always with the best effect, or that they who are so acted upon, should not sometimes suffer injury from the inadequate or ill appropriated influence that is exerted over them.
