This pure and rational idea of the beautiful--supposing it can be placed in evidence--cannot be taken from any real and special case, and must, on the contrary, direct and give sanction to our judgment in each special case. It must therefore be sought for by a process of abstraction, and it ought to be deduced from the simple possibility of a nature both sensuous and rational; in short, beauty ought to present itself as a necessary condition of humanity. It is therefore essential that we should rise to the pure idea of humanity, and as experience shows us nothing but individuals, in particular cases, and never humanity at large, we must endeavour to find in their individual and variable mode of being the absolute and the permanent, and to grasp the necessary conditions of their existence, suppressing all accidental limits. No doubt this transcendental procedure will remove us for some time from the familiar circle of phaenomena and the living presence of objects, to keep us on the unproductive ground of abstract ideas; but we are engaged in the search after a principle of knowledge solid enough not to be shaken by anything, and the man who does not dare to rise above reality will never conquer this truth. LETTER XI. If abstraction rises to as great an eievation as possible, it arrives at two primary ideas, before which it is obliged to stop and to recognise its limits. It distinguishes in man something that continues, and something that changes in cessantly. That which continues it names his person; that which changes his position, his condition. The person and the condition, I and my determinations, which we represent as one and the same thing in the neces sary being, are eternally distinct in the finite being. Not withstanding all continuance in the person, the condition changes; in spite of all change of condition, the person remains. We pass from rest to activity, from emotion to indifference, from assent to contradiction, but we are always we ourselves, and what immediately springs from ourselves remains. It is only in the absolute subject that all his determinations continue with his personality. All that Divinity is, it is because it is so; consequently it is eternally what it is, because it is eternal. As the person and the condition are distinct in man, be cause he is a finite being, the condition cannot be founded on the person, nor the person on the condition. Admitting the second case, the person would have to change; and in the former case, the condition would have to continue. Thus in either supposition either the personality or the quality of a finite being would necessarily cease. It is not because we think, feel, and will, that we are; it is not because we are that we think, feel, and will. We are because we are. We feel, think, and will, because there is out of us something that is not ourselves.
