It is difficult to string together a more insubstantial mass of contradictions. But Batteux is rivalled and outdone by the English philosophers or rather scribblers on Æsthetic or rather on things in general which sometimes accidentally include æsthetic facts. Happening to find in Lomazzo some words attributed to Michæl Angelo on the beauty of shapes, Hogarth the artist took into his head the idea that the figurative arts can be regulated by a special principle which can be expressed in a particular fine.[2] Filled with this discovery, in 1745 he designed a frontispiece for a volume of his engravings; it depicted a painter's palette scored across with an undulating line and the words _The Line of Beauty._ Public curiosity was immediately aroused by this hieroglyphic, to be satisfied a little later by the publication of his book _The Analysis of Beauty_ (1753).[3] In this he combated the mistake of judging pictures either by the subject or the excellence of the imitation instead of by their form, which is the true essential of art and is composed "of symmetry, variety, uniformity, simplicity, intricacy and quantity; all things which co-operate in the production of beauty, correcting and restraining each other as required."[4] But immediately afterwards Hogarth proclaims that there must also be correspondence and agreement with the thing copied; for "regularity, uniformity and symmetry give pleasure in so far only as they serve to give the illusion of faithful correspondence."[5] Further on, the reader learns that "amongst the immense variety of undulating lines which may be conceived, there is but one which truly merits the name of the Line of Beauty, and this is a precisely serpentine line which may be called the Line of Grace."[6] Again, we are told that intricacy of lines is beautiful because "the active mind likes to be engaged," and the eye delights in being "guided in a sort of hunt."[7] A straight line has no beauty, and the pig, the bear, the spider and the toad are ugly because devoid of undulating lines.[8] The ancients showed much judgement in the management and grouping of lines, "varying from the precise line of grace only on those occasions when the character or action demanded."[9] [Sidenote: _E. Burke._] With similar indecision Edmund Burke wavers between the principle of imitation and other heterogeneous or imaginary principles in his book, _An Enquiry into the Origin of our Ideas of the Sublime and the Beautiful_ (1756). He observes, "Natural properties contained in an object give pleasure or displeasure to the imagination: beyond this, however, imagination may delight in the likeness of a copy to its original"; he asserts that from "these two reasons" arises the whole pleasure of imagination.[10]
