Euripides writes:

“Why? seeing the wealth we have uncertain is,

Why don’t we live as free from care, as pleasant

As we may?”

Similarly also, the comic poet Diphilus having said:

“The life of men is prone to change,”—

Posidippus says:

“No man of mortal mould his life has passed

From suffering free. Nor to the end again

Has continued prosperous.”
