Truly the singing of birds is a great solace and pleasure to us, and all other animals. This fact is not, I believe, so much due to the sweetness of the sounds, nor to their variety and harmony, as to the joyful signification of songs generally, and those of birds in particular. Birds laugh, as it were, to show their contentment and happiness. It may therefore be said that they partake in a degree of man's privilege of laughter, unpossessed by other animals. Now some people think that man may as well be termed a laughing animal, as an animal possessed of mind and reason; for laughter seems to them quite as much peculiar to man as reason. And it is certainly wonderful that man, the most wretched and miserable of all creatures, should have the faculty of laughter, which is wanting in other animals. Marvellous also is the use we make of this faculty! We see people suffering from some terrible calamity or mental distress, others who have lost all love of life, and regard every human thing as full of vanity, who are almost incapable of joy, and deprived of hope, laugh nevertheless. Indeed, the more such men realise the vanity of hope, and the misery of life, the fewer their expectations and pleasures, so much the more do they feel inclined to laugh. Now it is scarcely possible to explain or analyse the nature of laughter in general, and its connection with the human mind. Perhaps it may aptly be termed a species of momentary folly or delirium. For men can have no reasonable and just cause for laughter, because nothing really satisfies nor truly pleases them. It would be curious to discover and trace out the history of this faculty. There is no doubt that in man's primitive and wild state, it was expressed by a peculiar gravity of countenance, as in other animals, who show it even to the extent of melancholy. For this reason I imagine that laughter not only came into the world after tears, which cannot be questioned, but that a long time passed before it appeared. During that time, neither the mother greeted her child with a smile, nor did the child smilingly recognise her, as Virgil says. And the reason why, in the present day, among civilised people, children smile as soon as they are born, is explainable by virtue of example: they see others smile, therefore they also smile. It is probable that laughter originated in drunkenness,[1] another peculiarity of the human race. This vice is far from being confined to civilised nations, for we know that scarcely any people can be found that do not possess an intoxicating liquor of some kind, which they indulge in to excess. And this cannot be wondered at, when we remember that men, the most unhappy of all animals, are above all pleased with anything that easily alienates their minds, such as self-forgetfulness, or a suspension of their usual life; from which interruption and temporary diminution of the sense and knowledge of their peculiar evils they receive no slight benefit. And whereas
