To be happy in this world, especially when youth is past, it is necessary to feel oneself not merely an isolated individual whose day will soon be over, but part of the stream of life slowing on from the first germ to the remote and unknown future.
Happiness is a sunbeam which may pass through a thousand bosoms without losing a particle of its original ray; nay, when it strikes on a kindred heart, like the converged light on a mirror, it reflects itself with redoubled brightness. It is not perfected till it is shared.
Most of us experience happiness when we are enjoying life and feeling free, enjoying the process and products of our creative and intellectual processes, enjoying the ecstasy of transcendent oneness with the universe.
Happiness is a matter of one's most ordinary everyday mode of consciousness being busy and lively and unconcerned with self. To be damned is for one's ordinary everyday mode of consciousness to be unremitting agonizing preoccupation with self.
There is something ridiculous and even quite indecent in an individual claiming to be happy. Still more a people or a nation making such a claim. The pursuit of happiness... is without any question the most fatuous which could possibly be undertaken. This lamentable phrase the pursuit of happiness is responsible for a good part of the ills and miseries of the modern world.
