Nobody can fully understand the meaning of love until he's owned a dog. He can show you more honest affection with a flick of his tail than a man can gather through a lifetime of handshakes.
From thence the beasts be brought in, killed and clean washed by the hands of their bondsmen. For they permit not their free citizens to accustom themselves to the killing of beasts, through the use whereof they think clemency, the gentlest affection of our nature, by little and little to decay and perish.
It is better to give love. Hatred is a low and degrading motion and is so poisonous that no man is strong enough to use it safely. The hatred we think we are directing against some person or thing or system has a devilish way of turning back upon us. When we seek revenge we administer slow poison to ourselves. When we administer affection it is astonishing what magical results we obtain.
Affection towards clan-mates, love of children, deference to authority, disinclination to kill those who have reminded us of common humanity, even some respect for property; these features of human life do not, it seems, stem from our intellectual gifts. We share them with our cousins.
To laugh often and much; To win the respect of intelligent people and the affection of children; To earn the approbation of honest critics and endure the betrayal of false friends; To appreciate beauty; To find the best in others; To give of one's self; To leave the world a bit better, whether by a healthy child, a garden patch, or a redeemed social condition; To have played and laughed with enthusiasm and sung with exultation; To know even one life has breathed easier because you have lived - This is to have succeeded.
