To educate yourself for the feeling of gratitude means to take nothing for granted, but to always seek out and value the kindness that stands behind the action. Nothing that is done for you is a matter of course. Everything originates in a will for the good, which is directed at you. Train yourself never to put off the word or action for the expression of gratitude.
Albert SchweitzerNot less strong than the will to truth must be the will to sincerity. Only an age, which can show the courage of sincerity, can possess truth, which works as a spiritual force within it.
Albert SchweitzerWe wander through this life together in a semi-darkness in which none of us can distinguish exactly the features of his neighbour. Only from time to time, through some experience that we have of our companion, or through some remark that he passes, he stands for a moment close to us, as though illuminated by a flash of lightning. Then we see him as he really is.
Albert SchweitzerWhat does Reverence for Life say abut the relations between [humanity] and the animal world? Whenever I injury any kind of life I must be quite certain that it is necessary. I must never go beyond the unavoidable, not even in apparently insignificant things. The farmer who has mowed down a thousand flowers in his meadow in order to feed his cows must be careful on his way home not to strike the head off a single flower by the side of the road in idle amusement, for he thereby infringes on the law of life without being under the pressure of necessity.
