_Properly an Emotion._--Among the sources of rational enjoyment which the constitution of our nature affords, must be reckoned the feeling awakened by the perception of the _ludicrous_. We class this among the emotions, inasmuch as it is a matter of feeling, and of pleasurable feeling, differing in its nature not more from the intellectual faculties, on the one hand, than from the affections and desires, on the other. It is a species of joy or gladness, a pleasurable excitement of feeling, awakened by a particular class of objects. Whatever else may be true of the feeling in question, the character of agreeableness is inseparable from it. It falls, therefore, properly into that class of feelings which comprises the various modifications of joy and sorrow, and which we have denominated simple emotions. _Why rational._--We term it _rational_, rather than instinctive, inasmuch as it implies, if I mistake not, the exercise of the higher intellectual faculties. It is the prerogative of reason. The brute nature has no perception, and of course no enjoyment, of the ludicrous. The idiot has none. The uncultivated savage nature has it only in a slight degree. In this respect the feeling under consideration is quite analogous to the enjoyment of the beautiful and sublime, and also to the feeling awakened in view of right or wrong action, the approbation or disapprobation of our past conduct. All these, though founded in our nature and constitution, are rational rather than instinctive, as implying the exercise of those faculties which more peculiarly distinguish man from the lower orders of being. _In what Way to be defined._--To define precisely the emotion of the ludicrous would be as difficult as to give an exact definition of any other feeling. We must content ourselves, as in all such cases, by determining the circumstances or conditions which give occasion for the feeling. Though we cannot define the emotion itself, we can carefully observe and specify the various objects and occasions that give rise to it.
