A double distinction may be made amongst human activities. In the first place, there are activities which we presume to be constituted in the same manner in all men (such as the logical activity) and are called activities of identity; and others whose diversity is presumed, which are called activities of difference or individual activities. Secondly, there are activities which exhaust themselves in the internal life, and others which actualize themselves in the external world: immanent activities and practical activities. To which of the two classes in each of the two orders does artistic activity belong? There can be no doubt of its different modes of development, if not actually in each individual person, at least in different peoples and nations; therefore it belongs properly to activities of difference or individual activities.[6] As for the other distinction, it is true that art does realize itself in the external world, but this fact is something superadded ("_ein später Hinzukommendes_") "which stands to the internal fact as the communication of thought by means of speech or writing stands to thought itself": art's true work is the internal image ("_das innere Bild ist das eigentliche Kunstwerk_"). Exceptions to this might be adduced, such as mimicry; but they would be apparent only. Between a really angry man and the actor who plays the part of an angry man on the stage there is this difference: in the second case anger appears as controlled and therefore beautiful; that is, the internal image is in the actor's soul interposed between the fact of passion and its physical manifestation.[7] Artistic activity "belongs to those human activities in which we presuppose the individual in its differentiation; it belongs equally to those activities developing essentially within themselves and not completing themselves in any external world. Art, therefore, is an immanent activity in which we presuppose differentiation." Internal, not practical: individual, not universal or logical. [Sidenote: _Artistic truth and intellectual truth._]
