Let me give you a definition of ethics: It is good to maintain and further life it is bad to damage and destroy life.

The thinking (person) must oppose all cruel customs, no matter how deeply rooted in tradition and surrounded by a halo. When we have a choice, we must avoid bringing torment and injury into the life of another.

The friend of nature is the man who feels himself inwardly united with everything that lives in nature, who shares in the fate of all creatures, helps them when he can in their pain and need, and as far as possible avoids injuring or taking life.

There slowly grew up in me an unshakable conviction that we have no right to inflict suffering and death on another living creature, unless there is some unavoidable necessity for it.

You ask me for a motto. Here it is: SERVICE.

Our age is bent on trying to make the barren tree of skepticism fruitful by tying the fruits of truth on its branches.

The city of truth cannot be built on the swampy ground of skepticism.
