Human beings are the only animals of which I am thoroughly and cravenly afraid.

Man is a two-legged animal without feathers.

Mankind is made great or little by its own will.

If man had created man, he would be ashamed of his performance.

The human race was always interesting and we know by its past that it will always continue so, monotonously.

If your heart is touched and tender Towards sinner log and low, It might help him to do better If you could only tell him so.
