The truth lies somewhere between these two aesthetics [static Cubism and dynamic Futurism]. The 'pure form' of Ingres led inevitably to a life-less Platonism; the lyricism and Romanticism of Eugène Delacroix no longer tailed with our cerebral and geometric age.... as in all great ages, today's artwork must be the synthesis of these two things.
