Eine jede Wissenschaft ist für sich ein System; und es ist nicht genug, in ihr nach Principien zu bauen und also technisch zu verfahren, sondern muß … - Immanuel Kant

Nature, therefore, is subject with absolute precision to all the precepts of geometry as to all the properties of space there demonstrated, this being the subjective condition, not hypothetically but intuitively given, of every phenomenon in which nature can ever be revealed to the senses.

The child must be brought up free (that he allow others to be free). He must learn to endure the restraint to which freedom subjects itself for its own preservation (experience no subordination to his command). Thus he must be disciplined. This precedes instruction. Training must continue without interruption. He must learn to do without things and to be cheerful about it. He must not be obliged to dissimulate, he must acquire immediate horror of lies, must learn so to respect the rights of men that they become an insurmountable wall for him. His instruction must be more negative. He must not learn religion before he knows morality. He must be refined, but not spoiled (pampered). He must learn to speak frankly, and must assume no false shame. Before adolescence he must not learn fine manners ; thoroughness is the chief thing. Thus he is crude longer, but earlier useful and capable.

Finer feeling, which we now wish to consider, is chiefly of two kinds: the feeling of the *sublime* and that of the *beautiful*. The stirring of each is pleasant, but in different ways. The sight of a mountain whose snow-covered peak rises above the clouds, the description of a raging storm, or Milton's portrayal of the infernal kingdom, arouse enjoyment but with horror; on the other hand, the sight of flower strewn meadows, valleys with winding brooks and covered with grazing flocks, the description of Elysium, or Homer's portrayal of the girdle of Venus, also occasion a pleasant sensation but one that is joyous and smiling. In order that the former impression could occur to us in due strength, we must have *a feeling of the sublime*, and, in order to enjoy the latter well, *a feeling of the beautiful*. Tall oaks and lonely shadows in a sacred grove are sublime; flower beds, low hedges and trees trimmed in figures are beautiful. Night is sublime; day is beautiful. Temperaments that possess a feeling for the sublime are drawn gradually, by the quiet stillness of a summer evening as the shimmering light of the stars breaks through the brown shadows of night and the lonely moon rises into view, into high feelings of friendship, of disdain for the world, of eternity. The shining day stimulates busy fervor and a feeling of gaiety. The sublime *moves*, the beautiful *charms*.
