The consciousness of virtue, even if one only places oneself in thought in the position of a virtuous man, diffuses in the mind a multitude of sublime and restful feelings and a boundless prospect of a joyful future, to which no expression measured by a definite concept completely attains.[85] In a word the aesthetical Idea is a representation of the Imagination associated with a given concept, which is bound up with such a multiplicity of partial representations in its free employment, that for it no expression marking a definite concept can be found; and such a representation, therefore, adds to a concept much ineffable thought, the feeling of which quickens the cognitive faculties, and with language, which is the mere letter, binds up spirit also. The mental powers, therefore, whose union (in a certain relation) constitutes _genius_ are Imagination and Understanding. In the employment of the Imagination for cognition it submits to the constraint of the Understanding and is subject to the limitation of being conformable to the concept of the latter. On the other hand, in an aesthetical point of view it is free to furnish unsought, over and above that agreement with a concept, abundance of undeveloped material for the Understanding; to which the Understanding paid no regard in its concept, but which it applies, though not objectively for cognition, yet subjectively to quicken the cognitive powers and therefore also indirectly to cognitions. Thus genius properly consists in the happy relation [between these faculties], which no science can teach and no industry can learn, by which Ideas are found for a given concept; and on the other hand, we thus find for these Ideas the _expression_, by means of which the subjective state of mind brought about by them, as an accompaniment of the concept, can be communicated to others. The latter talent is properly speaking what is called spirit; for to express the ineffable element in the state of mind implied by a certain representation and to make it universally communicable--whether the expression be in speech or painting or statuary--this requires a faculty of seizing the quickly passing play of Imagination and of unifying it in a concept (which is even on that account original and discloses a new rule that could not have been inferred from any preceding principles or examples), that can be communicated without any constraint [of rules].[86] * * * * *
