Taste, like the Judgement in general, is the discipline (or training) of Genius; it clips its wings closely, and makes it cultured and polished; but, at the same time, it gives guidance as to where and how far it may extend itself, if it is to remain purposive. And while it brings clearness and order into the multitude of the thoughts, it makes the Ideas susceptible of being permanently and, at the same time, universally assented to, and capable of being followed by others, and of an ever-progressive culture. If, then, in the conflict of these two properties in a product something must be sacrificed, it should be rather on the side of genius; and the Judgement, which in the things of beautiful art gives its decision from its own proper principles, will rather sacrifice the freedom and wealth of the Imagination than permit anything prejudicial to the Understanding. For beautiful art, therefore, _Imagination_, _Understanding_, _Spirit_, and _Taste_ are requisite.[87] § 51. _Of the division of the beautiful arts_ We may describe beauty in general (whether natural or artificial) as the _expression_ of aesthetical Ideas; only that in beautiful Art this Idea must be occasioned by a concept of the Object; whilst in beautiful Nature the mere reflection upon a given intuition, without any concept of what the object is to be, is sufficient for the awakening and communicating of the Idea of which that Object is regarded as the _expression_. If, then, we wish to make a division of the beautiful arts, we cannot choose a more convenient principle, at least tentatively, than the analogy of art with the mode of expression of which men avail themselves in speech, in order to communicate to one another as perfectly as possible not merely their concepts but also their sensations.[88]--This is done by _word_, _deportment_, and _tone_ (articulation, gesticulation, and modulation). It is only by the combination of these three kinds of expression that communication between the speaker [and his hearers] can be complete. For thus thought, intuition, and sensation are transmitted to others simultaneously and conjointly. There are, therefore, only three kinds of beautiful arts; the arts of _speech_, the _formative_ arts, and the art of the _play of sensations_ (as external sensible impressions). We may also arrange a division by dichotomy; thus beautiful art may be divided into the art of expression of thoughts and of intuitions; and these further subdivided in accordance with their form or their matter (sensation). But this would appear to be too abstract, and not so accordant with ordinary concepts. (1) The arts of SPEECH are _rhetoric_ and _poetry_. _Rhetoric_ is the art of carrying on a serious business of the Understanding as if it were a free play of the Imagination; _poetry_, the art of conducting a free play of the Imagination as if it were a serious business of the Understanding.
