"The proletarian revolution ought now, by a little ray of kindness, to illuminate the gloomy life of prisoners, shorten Draconian sentences, abolish barbarous punishments - the use of manacles and whippings - improve, as far as possible, the medical attention, the food allowance, and the conditions of labor. That is a duty of honor."
January 1, 1970
