The           which all feel that a viper is a
poisonous animal, and that a tiger is constrained, by the inevitable
condition of his existence, to devour men, does not induce us to avoid
them lass sedulously, or, even more, to hesitate in destroying them: but
he would surely be of a hard heart who, meeting with a serpent on a
desert island, or in a situation where it was incapable of injury,
should wantonly deprive it of existence.
