The American Paradox

“ A Person of Humanity, wishing to establish his own character, also establishes the character of others.” — Confucius

“ The great secret of morals is love, or a going out of our own nature, and an identification of ourselves with the beautiful which exists in thought, action or person, not our own. A man, to be greatly good, must imagine intensely and comprehensively; he must put himself in the place of another and of many others; the pains and pleasures of his species must become his own. The great instrument of moral good is the imagination.” — Shelley

Designed to be Kind “ At the most fundamental level our nature is compassionate,

and that cooperation, not conflict, lies at the heart of the basic principles that govern our human existence.” — His Holiness, the Dalai Lama

“ …the social instincts lead an animal to take pleasure in the society of his fellows, to feel a certain amount of sympathy with them, and to perform various services for them… the greater strength of the social or maternal instincts than that of any other instinct or motive; for they are performed too instantaneously for reflection, or for pleasure or even misery might be felt. In a timid man, on the other hand, the instinct of self-preservation might be so strong…” — Charles Darwin, The Descent of Man
