But free circulation of thought and feeling composes the chief influence of free institutions on the mind. The beauty, union, and elevation of society depend upon the action and re-action of mind. Indeed, this reciprocal influence of mind is the final cause in the formation of society. Where it is unfelt all relations, political and social, are frail and disregarded. If we look through society we shall find that all national mental greatness and power, originates in the influence which a few mighty minds exert in setting the great mass of mind to thinking and feeling. How great have been the effects of the minds of the Newtons, Bacons, Ciceros and Luthers on the world! How many millions of minds have they not excited to strong and elevated action! Now, free governments, from their very nature, encourage this interchange, this mutual action of mind on mind. And mark the results. The original brightness of one mind throws new light on the path of another. A superior thought, like the blast of the Highland warrior's trump bounding from crag to crag, and causing, quick as sound, a hundred minds to beat for action, spreads with electric rapidity through every nerve of the social frame. Thoughts once clouded in darkness assume a blinding brightness. Thoughts once confused and incomprehensible are mastered and imbodied in enchanting forms. Patient and ambitious investigation, surmounting every obstacle, and penetrating to the lowest depths of knowledge, brings forth its rich treasures; truths, brilliant and irresistible. Free discussion is awakened, eliciting talent, intellectual energies and glories. Nor is this all. In philosophy, a few mighty minds arise and unfold new principles in human nature; and, immediately, a spirit of revolution, rapid but glorious, rages through society, destroying false and unnatural relations, and strengthening those that are genuine by holier and imperishable ties. In literature, a few mighty minds arise, profound in thought, imperial in fancy and conception, which like so many meridian suns, casting their beams upon the mental world, draw forth the native graces, and beauties, and grandeur of mind, and disseminate through every department of letters an influence enlivening and beautifying: an influence, which arouses the slumbering spirit of poetry, and throws an immortal radiance over the Elysian realms of fiction. In science, a few mighty minds arise, expose old fallacies, explore the rich mines of the earth, develope the mysterious principles of matter, explain the nature of their application, and suddenly an unusual mental splendor encircles the temple of learning. Art wields her sceptre with greater skill and precision, improving and adorning every branch of mechanism, that administers to the uses and comforts of society. And this influence of these few mighty minds on the general mind of society reacts in resilient bounds, again acts, and again rebounds, continually increasing in vigor and majesty.
