A quote
But this very fall has in it nothing evil, if you consider the end, after which nature lays no man lower. The universal limit is near; yes, there is near us the point where the prosperous man is upset, and the point where the unfortunate is set free. It is we ourselves that extend both these limits, lengthening them by our hopes and by our fears. If, however, you are wise, measure all things according to the state of man; restrict at the same time both your joys and your fears. Moreover, it is worth while not to rejoice at anything for long, so that you may not fear anything for long.
