There are, therefore, certain rules with regard to conduct that we can arrive at and justify by strictly scientific methods.

We can demonstrate that there are certain actions which we must never tolerate, and which we must join together, as best we may, to suppress.

Actions, for instance, that would tend to generate pestilence, or to destroy our good faith in our fellows, or to render our lives and property insecure, are actions the badness of which can be scientifically verified.
But the _general good_ by which these actions are tested is something quite distinct from happiness, though it undoubtedly has a close connection with it.

It is no kind of happiness, high or low, in particular; it is simply those negative conditions required equally by every kind.

If we are to be happy in any way, no matter what, we must of course have our lives, and, next to our lives, our health and our possessions secured to us.
