Stultorum plena sunt omnia.
(M. Tullius Cicero, Ad Familiares 9.22.4)

Everything is full of fools.

Pon = stool-TOH-room PLAY-nah soont OHM-nee-ah.

Comment: Cicero is not pleased with the stupid things people say and
do in and out of the court, in and about giving their word of "honor".
He speaks as the attorney par excellence, and we would not expect
him to be very patient with foolish people saying foolish things.

Most of us probably find ourselves in those situations where we have
some appreciation for how a thing should be--because of our education,
experiences, responsiblities, etc. We can identify foolish actions
and behaviors in our realm of expertise, and can be fairly justified
in not entertaining such fools.

There is another take on the "fool" though, that is a good balance for
us when we take ourselves too seriously. He is the Fool of the court,
the Jester, the eternal child, the one who is free to play and take
risks and laugh out loud. He shows up in people all around us every
day, reminding us that sometimes it is just better to let go and
laugh, to try something new and out of the ordinary. This kind of
Fool gets us out of our heads, off our self-righteous mounts, and
invites us to climb mountains, set sail, jump off a cliff into the
water below, and to laugh.

The whole universe is full of fools, some to beware, some to befriend.
