_Synthesis._--The most original and general characteristic of the poets who are the product of insanity is precisely the forcing of the mind to a state so at variance with previous conditions of life and culture. In many, it is true, the only result of this effect is a continuous flow of epigrams, plays upon words, and assonances--puns, in short, such as are praised in society as evidences of wit; though it is no wonder that they should abound in lunatic asylums, being, as they are, the very negative of truth and logic. This tendency, or, at least, the tendency to alliteration and rhyme, is evident in all their works, even those written in prose. Yet, on the other hand, we not rarely meet with improvised philosophers, who in their utterances reproduce parts of the systems of the Positivists, of Epicurus and Comte; the brain, quickened by insanity, being able to seize upon those salient points of truth from which the systems named took their rise, and that because these men have less hatred of novelty, and more originality, than normal people. Their most salient characteristic--originality heightened to the point of absurdity--is due to the overflowing of the imagination which can no longer be restrained within the bounds of logic and common sense. It is natural that the mind which has been most injured, or is by nature the most deficient, should exceed most in this respect. We need only refer now to the pretended metamorphosis and journeyings of the soul of P---- of Siena, and the writings of M---- of Pesaro, who had carried his passion for the Greek language so far as to invent a new idiom, in which gravel was called _lithiasis_, the sea, _equor_, convictions, _agonies_, the world, a _vase_.[298] Their more rapid association of ideas, and livelier imagination, often enable them to solve problems which more cultivated, but normal, intellects can scarcely attack with success. Another peculiarity characteristic of them, but which, be it noted, is often found also in the writings of criminals, is the tendency to speak of themselves or their companions, and to write autobiographies, abandoning themselves without restraint to the torrent of ambition or love. But with insane persons the form of expression is much less artificial than that used by criminals, in whose writings one finds more coherence but less creative power and originality. The use of assonances in place of reasoning is entirely peculiar to the insane, as also the use of special words, or words used in a peculiar sense, and the exaggerated importance attributed to the most trifling things. “_C’est le travail des fous d’épuiser leurs cervelles_ _Sur des riens fatigants, sur quelques bagatelles_,” said Hécart in his _Gualana_, which, by the way, is only the work of a mattoid.
