Seneca,
Moral letters to Lucilius — Letter 63…
“ But what man will ever be so blessed with that ideal steadfastness of soul, unless he has already risen far above the reach of Fortune? Even such a man will be stung by an event like this, but it will be only a sting. We, however, may be forgiven for bursting into tears, if only our tears have not flowed to excess, and if we have checked them by our own efforts. Let not the eyes be dry when we have lost a friend, nor let them overflow. ”
