There are seven characteristics which differentiate the wise man from the fool.
A wise man:
- Does not speak before one who is wiser than he.
- Does not interrupt his friend.
- Does not fear to respond.
- Asks questions to the point and responds likewise.
- Responds first to what he was asked first.
- When asked about something he has not learned about he says so.
- Recognizes the truth in views which contradict his own.
... and the opposite is the case as for the fool.
