Albert Schweitzer (14 January 1875 – 4 September 1965) was an Alsatian polymath. He was a theologian, organist, writer, humanitarian, philosopher, and physician. A Lutheran, Schweitzer challenged both the secular view of Jesus as depicted by the historical-critical method current at this time, as well as the traditional Christian view. His contributions to the interpretation of Pauline Christianity concern the role of Paul's mysticism of "being in Christ" as primary and the doctrine of Justification by Faith as secondary.

It was quite incomprehensible to me …why in my evening prayers I should pray for human beings only. So when my mother had prayed with me and had kissed me goodnight, I used to add silently a prayer that I had composed myself for all living creatures. It ran thus: "O Heavenly Father, protect and bless all things that have breath; guard them from all evil, and let them sleep in peace. "
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.
