imagination and making itself agreeable to the intuitive faculties; if it applies this law not only to the _operation_, but also to the _matter_ itself; if it follows this rule not only to arrange the materials, but also to choose them. When this is the case the first consideration is not the _things_ themselves, but the best mode of presenting them so as to recommend them to the senses. The logical sequence of conceptions of which only the strictness should have been hidden from us is rejected as a disagreeable impediment. Perfection is sacrificed to ornament, the truth of the parts to the beauty of the whole, the inmost nature of things to the exterior impression. Now, directly the substance is subordinated to form, properly speaking it ceases to exist; the statement is empty, and instead of having extended our knowledge we have only indulged in an amusing game. The writers who have more wit than understanding and more taste than science, are too often guilty of this deception; and readers more accustomed to feel than to think are only too inclined to forgive them. In general it is unsafe to give to the æsthetical sense all its culture before having exercised the understanding as the pure thinking faculty, and before having enriched the head with conceptions; for as taste always looks at the carrying out and not at the basis of things, wherever it becomes the only arbiter, there is an end of the essential difference between things. Men become indifferent to reality, and they finish by giving value to form and appearance only. Hence arises that superficial and frivolous _bel esprit_ that we often see hold sway in social conditions and in circles where men pride themselves, and not unreasonably, on the finest culture. It is a fatal thing to introduce a young man into assemblies where the Graces hold sway before the Muses have dismissed him and owned his majority. Moreover, it can hardly be prevented that what completes the external education of a young man whose mind is ripe turns him who is not ripened by study into a fool. I admit that to have a fund of conceptions, and not form, is only a half possession. For the most splendid knowledge in a head incapable of giving them form is like a treasure buried in the earth. But form without substance is a shadow of riches, and all possible cleverness in expression is of no use to him who has nothing to express. Thus, to avoid the graces of education leading us in a wrong road, taste must be confined to regulating the external form, while reason and experience determine the substance and the essence of conceptions. If the impression made on the senses is converted into a supreme _criterion_, and if things are exclusively referred to sensation, man will never cease to be in the service of matter; he will never clear a way for his intelligence; in short, reason will lose in freedom in proportion as it allows imagination to usurp undue influence.
