Kindness works simply and perseveringly; it produces no strained relations which prejudice its working; strained relations which already exist it relaxes. Mistrust and misunderstanding it puts to flight, and it strengthens itself by calling forth answering kindness. Hence it is the furthest reaching and the most effective of all forces.
Albert SchweitzerVery little of the great cruelty shown by men can really be attributed to cruel instinct. Most of it comes from thoughtlessness or inherited habit. The roots of cruelty, therefore, are not so much strong as widespread. But the time must come when inhumanity protected by custom and thoughtlessness will succumb before humanity championed by thought. Let us work that this time may come.
