The only freedom which deserves the name, is that of pursuing our own good in our own way, so long as we do not attempt to deprive others of theirs, … - John Stuart Mill

Supposing it true that contrary to appearances these horrors when perpetrated by Nature, promote good ends, still as no one believes that good ends would be promoted by our following the example, the course of Nature cannot be a proper model for us to imitate. Either it is right that we should kill because nature kills ; torture because nature tortures ; ruin and devastate because nature does the like; or we ought not to consider at all what nature does, but what it is good to do. If there is such a thing as a reductio ad absurdum, this surely amounts to one. If it is a sufficient reason for doing one thing, that nature does it, why not another thing? If not all things, why anything?

The strongest of all arguments against the interference of the public with purely personal conduct, is that when it does interfere, the odds are that it interferes wrongly, and in the wrong place.
