Happiness is something final and complete in itself, as being the aim and end of all practical activities whatever .... Happiness then we define as the active exercise of the mind in conformity with perfect goodness or virtue.
There is nothing more distressing ... than the hard, scoffing spirit which treats the allegation of dishonesty in a public man as a cause for laughter. Such laughter is worse than the crackling of thorns under a pot, for it denotes not merely the vacant mind, but the heart in which high emotions have been choked before they could grow to fruition.
Music makes me forget my real situation. It transports me into a state which is not my own. Under the influence of music I really seem to feel what I do not feel, to understand what I do not understand, to have powers which I cannot have. Music seems to me to act like yawning or laughter; I have no desire to sleep, but I yawn when I see others yawn; with no reason to laugh, I laugh when I hear others laugh. And music transports me immediately into the condition of soul in which he who wrote the music found himself at that time. ~The Kreutzer Sonata
Avoid excessive merriment. A mind in that state never becomes calm; it becomes fickle. Excessive merriment will always be followed by sorrow. Tears and laughter are near kin. People so often run from one extreme to the other.
Will a day come when the race will detect the funniness of these juvenilities and laugh at them—and by laughing at them destroy them? For your race, in its poverty, has unquestionably one really effective weapon—laughter. Power, Money, Persuasion, Supplication, Persecution--these can lift at a colossal humbug,—push it a little— crowd it a little—weaken it a little, century by century: but only Laughter can blow it to rags and atoms at a blast. Against the assault of Laughter nothing can stand. - "The Chronicle of Young Satan," Mysterious Stranger Manuscripts
Laughter springs from the lawless part of our nature, and is purifying only in so far as there is a natural and unschooled goodness in the human heart.
I must say that, beyond occasionally exposing me to laughter, my constitutional shyness has been no dis-advantage whatever. In fact I can see that, on the contrary, it has been all to my advantage.
That older and greater church to which I belong: the church where the oftener you laugh the better, because by laughter only can you destroy evil without malice
But at the same time, in reality, what a difference there is between the world today, and what it used to be! And with the passage of more time, some two or three hundred years, say, people will look back at our own times with horror, or with sneering laughter, because all of our present day life will appear so clumsy, and burdensome, extraordinarily inept and strange. Yes, certainly, what a life it will be then, what a life!
