(_a_) _First_, then, in the invention of the riddle, the point from which the process starts, is the apprehended meaning, the signification of it. (_b_) The _second_ step consists in the intentional selection of traits of character and other qualities from the common experience of the external world, which--such is always the aspect of Nature and external objects of every kind--are placed relatively to one another in piecemeal fashion, and in thus setting them forth in disparate contiguity, which makes their singularity the more striking. And inasmuch as they are so placed they are without the enfolding unity of mind, and their array and association intentionally distract has so far no intrinsic significance whatever. And yet for all that, and this is the other aspect of the riddle, they do expressly point to a unity in relation to which even traits to all appearance most heterogeneous contain, notwithstanding, both a real sense and significance. (_c_) This unity, which may be styled the subject of these distract predicates, is just the simple preconception, the word that solves our riddle, to discover or divine which from the apparently confused medley of the mode under which it is propounded is the riddle's problem. Thus interpreted we may call the riddle the facetiousness of symbolism, aware that it is such which puts to the proof acuteness of insight and aptness at putting things together, and finally, by stimulating the zest of solution, breaks into and destroys the very mode of presentation it has itself set up. In the main we shall find this, form, therefore, most employed in human speech, though we may find exceptional examples of it also in the plastic arts[89], architecture, horticulture, and painting. With regard to its historical appearance the East is first and foremost responsible, and we may date its advent in that intermediate and transitional period out of the more obtuse type of symbolism into one of more intelligent knowledge and comprehension. Entire peoples and historical epochs have taken delight in the solution of such problems. It also plays an important part in the Middle Ages among the Arabs and the Scandinavians, and as a particular example it is much in evidence in the minstrel tourneys on the Wartburg. In modern times it is mainly under the more modest guise of recreation and purely social pleasantry that we cross it. In the riddle we have opened a practically limitless field for witty and striking conceits, which in their reference to any given circumstance, occurrence, or object take the form of a play upon words or an epigrammatical sentence. On the one hand we have presented an object trite to a degree, on the other some conceit of the mind which emphasizes unexpectedly with conspicuous force some aspect or relation, which we failed to perceive in that object on first confronting it, and which now attaches to it the light of a new significance. 2.
