Herodotus on Laughter

There are three kinds of laughter, according to Herodotus:

- Those who are innocent of wrong-doing, but ignorant of their own vulnerability.

- Those who are mad.

- Those who are overconfident.

I like this because there is often something really wrong with laughter. But these are all reflections, more or less, of one of category. Those ignorant of their own vulnerability are by nature overconfident. Those who are mad are by nature ignorant. Those who are overconfident are naturally not mindful...
