As to Epicurus, quite shamelessly filching the end of Parasitic, he makes it the end of his conception of happiness. That the thing is plagiarism, and that pleasure does not concern Epicurus at all, but does concern the parasite, you can assure yourself from this line of reasoning. I for'my part consider that pleasure is first of all the freedom of the flesh from discomfort, and secondly, not having the spirit full of turbulence and commotion. Now then, each of these things is attained by the parasite, but neither by Epicurus. For with his inquiries about the shape of the earth, the infinitude of the universe, the magnitude of the sun, distances in space, primal elements, and whether the gods exist or not, and with his continual strife and bickering with certain persons about the end itself, he is involved not only in the troubles of man but in those of the universe. The parasite, however, thinking that everything is all right and thoroughly convinced it would not be any better if it were other than as it is, eats and sleeps in great peace and comfort, with nothing of that sort annoying him, flat on his back, with his arms and legs flung out, like Odysseus sailing home from Scheria.
