Seneca · On the fickleness of fortune
Letters 98.15
By these words, and words of a like kind, the malignity of the ulcer is quieted down; and I hope indeed that it can be reduced, and either cured or brought to a stop, and grow old along with the patient himself. I am, however, comfortable in my mind regarding him; what we are now discussing is our own loss—the taking-off of a most excellent old man. For he himself has lived a full life, and anything additional may be craved by him, not for his own sake, but for the sake of those who need his services.
Seneca, Letters to Lucilius 98.15, translated by Richard Mott Gummere
