Famous quote,-

"Be kind, for everyone you meet is fighting a hard battle."

Several persons have e-mailed me, presuming that the saying quoted above is from Philo. But I have not been able to verify it in any of Philo's works.
Some webpages also accredit it to Philo; more often, however, it is said to come from Plato, but with no further references.

Can anyone out there help to locate the origin of this saying? Use the comment field below for your suggestions.
