Continuing the search for the _physical laws_ or for the _objective conditions of the beautiful_, it has been asked: To what physical facts does the beautiful correspond? To what the ugly? To what unions of tones, colours, sizes, mathematically determinable? Such inquiries are as if in Political Economy one were to seek for the laws of exchange in the physical nature of the objects exchanged. The constant infecundity of the attempt should have at once given rise to some suspicion as to its vanity. In our times, especially, has the necessity for an _inductive_ Aesthetic been often proclaimed, of an Aesthetic starting _from below_, which should proceed like natural science and not hasten its conclusions. Inductive? But Aesthetic has always been both inductive and deductive, like every philosophical science; induction and deduction cannot be separated, nor can they separately avail to characterize a true science. But the word "inductive" was not here pronounced accidentally and without special intention. It was wished to imply by its use that the aesthetic fact is nothing, at bottom, but a physical fact, which should be studied by applying to it the methods proper to the physical and natural sciences. With such a presupposition and in such a faith did inductive Aesthetic or Aesthetic of the inferior (what pride in this modesty!) begin its labours. It has conscientiously begun by making a collection of _beautiful things_, for example of a great number of envelopes of various shapes and sizes, and has asked which of these give the impression of the beautiful and which of the ugly. As was to be expected, the inductive aestheticians speedily found themselves in a difficulty, for the same objects that appeared ugly in one aspect would appear beautiful in another. A yellow, coarse envelope, which would be extremely ugly for the purpose of enclosing a love-letter, is, however, just what is wanted for a writ served by process on stamped paper. This in its turn would look very bad, or seem at any rate an irony, if enclosed in a square English envelope. Such considerations of simple common sense should have sufficed to convince inductive aestheticians, that the beautiful has no physical existence, and cause them to remit their vain and ridiculous quest. But no: they have had recourse to an expedient, as to which we would find it difficult to say how far it belongs to natural science. They have sent their envelopes round from one to the other and opened a _referendum_, thus striving to decide by the votes of the majority in what consists the beautiful and the ugly. We will not waste time over this argument, because we should seem to be turning ourselves into narrators of comic anecdotes rather than expositors of aesthetic science and of its problems. It is an actual fact, that the inductive aestheticians have not yet discovered _one single law_. [Sidenote] _Astrology of Aesthetic._
