What 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.

But merely accepting authoritarian truth, even if that truth has some virtue, does not bring skepticism to an end. To blindly accept a truth one has never reflected upon retards the advance of reason. Our world rots in deceit. . . .

But our age pretends to make a sterile tree bear fruit by tying fruits of truth onto its branches.

We wander through this life together in a semi-darkness in which none of us can distinguish exactly the features of his neighbour.

Then we see him as he really is.
