“It is actually a rather sorry tale. In the late nineteenth century most English economists thought that economics was about happiness. They thought of a persons happiness as in principle measurable, like temperature, and they thought we could compare one persons happiness with anothers. They also assumed that extra income brought less and less extra happiness as a person got richer.”
“Another study suggested that getting one extra hour of sleep each night would do more for a person's happiness than getting a $60,000 raise.”
“The source of love is deep in us and we can help others realize a lot of happiness. One word, one action, one thought can reduce another person’s suffering and bring that person joy.”
“What could be worse than another person's happiness? Not that his unhappiness would make us happy, but we need it in order to bear our own.”
“...the word 'love' designates a subjective condition in which the welfare and happiness of another person are essential to one's own happiness.”
“A happy person is not a person in a certain set of circumstances, but rather a person with a certain set of attitudes.”
