I was working today and needing to find the references to "continuous" pleasure and had a hard time finding them. Here are a couple:
Plutarch, Against Colotes, 17, p. 1117A: Such is ... the man who, in in the letter to Anaxarchus can pen such words as these: “But I, for my part, summon you to sustained pleasures and not to empty virtues, which fill us with vain expectations that destroy peace of mind.”
CICERO's ON ENDS
XII. The truth of the position that pleasure is the ultimate good will most readily appear from the following illustration. Let us imagine a man living in the continuous enjoyment of numerous and vivid pleasures alike of body and of mind, undisturbed either by the presence or by the prospect of pain: what possible state of existence could we describe as being more excellent or more desirable? One so situated must possess in the first place a strength of mind that is proof against all fear of death or of pain; he will know that death means complete unconsciousness, and that pain is generally light if long and short if strong, so that its intensity is compensated by brief duration and its continuance by diminishing severity. Let such a man moreover have no dread of any supernatural power; let him never suffer the pleasures of the past to fade away, but constantly renew their enjoyment in recollection, and his lot will be one which will not admit of further improvement.
