What is best for us

…matters do not stand so well with mankind that the majority should prefer the better course: the more people do a thing the worse it is likely to be. Let us therefore inquire, not what is most commonly done, but what is best for us to do, and what will establish us in the possession of undying happiness, not what is approved of by the vulgar, the worst possible exponents of truth.

Seneca, On Happy Life, II
