Much has been done of late to render the natural sciences familiar and attractive to the popular mind, by lectures and books that bring them within the comprehension of all: and it is to be hoped, that, beginning thus with the material parts of the universe, mankind may be gradually led from matter to mind, from science to religion. The forms of external things are easily reproduced in the mind as images, and this is why natural science addresses itself more readily to the mind than any other branch of learning. When men learn to look within, and perceive that the things of the mind are as genuine realities as the objects of the external world, Philosophy will become attractive; and when the preacher warms Theology into Religion by abandoning the technicalities of abstractions for the living realities of piety towards God and charity towards the neighbor, he will rejoice in a listening audience. The amount and the quality of that which we call originality, creative power, or genius, is entirely dependent upon the activity, force, and integrity of the Imagination. Talent belongs to Thought, and works only with facts and ideas as others have done before. It may be skilful, sensible, and faithful, but it can walk only in the old, beaten tracks. It can classify and arrange, but it can never discover or invent. Talent can understand and admire the mechanical powers; Genius puts them in harness, and makes them traverse land and sea to do his bidding. Talent loves to gaze on the fair forms of nature, and depicts them upon canvas with skill and truth, neither adding to nor subtracting from its model. Genius seizes upon the hints that nature gives, and without being false to her, makes use only of that which helps to make up the beautiful, the sublime, or the terrible; showing the power that is within nature rather than nature herself. Talent sees life as it is, and so describes it, if it ventures into the domain of literature. Genius sees life as it is capable of being, and hence comes poetry and romance, depicting heroes and heroines, monsters and fiends, types rather than representatives of the human race. Talent perceives only the actualities of things, Genius their possibilities. Talent is content with things as they are, while Genius is ever striving to bring out latent capacities in whatever it deals with. If true to its higher impulses, Genius is ever striving to come nearer "the first good, first perfect, and first fair"; if false, it degrades and deforms everything it touches. Mankind differ from each other in degree, but not in kind. By his power of thinking, a man has talent; by his power of imagining, genius. Quick-wittedness is genius in its lowest form,--genius applied to material life in its daily ongoings. The power for resource in emergencies is genius in a higher form. Invention--the putting together with an adequate purpose two things or ideas that never went together before--is genius in another form.
