_Super-sensuous._ Contrasted with and opposed to the sensuous. What is exclusively related to sense or imparted through the sensuous ideas is super-sensuous. See _Transcendental_. _Transcendental._ What exceeds the limits of sense and empirical observation. “I apply the term _transcendental_ to all knowledge which is not so much occupied with objects as with the mode of our cognition of these objects, so far as this mode of cognition is possible _à priori_.” Kant’s “Critique,” _op. cit._ p. 16. _Understanding_ (Verstand). The thought of faculty, the source of conceptions and notions (Begriffe) of the laws of logic, the categories, and judgment. LETTERS ON THE ÆSTHETICAL EDUCATION OF MAN. LETTER I. By your permission I lay before you, in a series of letters, the results of my researches upon _beauty_ and _art_. I am keenly sensible of the importance as well as of the charm and dignity of this undertaking. I shall treat a subject which is closely connected with the better portion of our happiness and not far removed from the moral nobility of human nature. I shall plead this cause of the beautiful before a heart by which her whole power is felt and exercised, and which will take upon itself the most difficult part of my task in an investigation where one is compelled to appeal as frequently to feelings as to principles. That which I would beg of you as a favor, you generously impose upon me as a duty; and, when I solely consult my inclination, you impute to me a service. The liberty of action you prescribe is rather a necessity for me than a constraint. Little exercised in formal rules, I shall scarcely incur the risk of sinning against good taste by any undue use of them; my ideas, drawn rather from within than from reading or from an intimate experience with the world, will not disown their origin; they would rather incur any reproach than that of a sectarian bias, and would prefer to succumb by their innate feebleness than sustain themselves by borrowed authority and foreign support. In truth, I will not keep back from you that the assertions which follow rest chiefly upon Kantian principles; but if in the course of these researches you should be reminded of any special school of philosophy, ascribe it to my incapacity, not to those principles. No; your liberty of mind shall be sacred to me; and the facts upon which I build will be furnished by your own sentiments; your own unfettered thought will dictate the laws according to which we have to proceed.
