In case my life should end with the cannibals, I hope they will write on my tombstone, 'We have eaten Dr. Schweitzer. He was good to the end.'

The great fault of all ethics hitherto has been that they believed themselves to have to deal only with the relations of man to man. In reality, however, the question is what is his attitude to the world and all life that comes within his reach.

In the past we have tried to make a distinction between animals which we acknowledge have some value and other which, having none, can be liquidated when we wish. This standard must be abandoned. Everything that lives has value simply as a living thing, as one of the manifestations of the mystery that is life.

Anyone who proposes to do good must not expect people to roll stones out of his way, but must accept his lot calmly if they even roll a few more on it. A strength which becomes clearer and stronger through experiences of such obstacles is the only strength that can conquer them. Resistance is only a waste of strength.

We need a boundless ethics which will include animals also.

Knowing all truth is less than doing a little bit of good.

Very 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.
