Technically it is true to say that the stoics, or some of them, did not despise the pleasure which was not a passion but a 'rational affection'. Erasmus, as usual, is making learned fun and perhaps remembering that, for Seneca, the 'pleasure' which is the final end of human endeavour is for the Epicurean identified with the 'virtue' which the stoics cultivate (de beata vita, 13).
