More than measure

According to some in Elysium, which is considered to be ruled by Cronos, live also those who are not yet born.

These souls swarm along the banks of the river Lethe (Oblivion). Some say that:

"They were all required to drink a measure of the water, and those who were not saved by their good sense, drank more than the measure, and each one as he drank forgot all things."

[Plato, Republic 10.618a]
