M. CICERO S. D. C. CASSIO
puto te iam suppudere, quem haec tertia iam epistula ante oppressit quam tu scidam aut litteram. sed non urgeo ; longiores enim exspectabo vel potius exigam. ego si semper haberem cui darem, vel ternas in hora darem ; is fit enim nescio qui ut quasi coram adesse videare cum scribo aliquid ad te, neque id κατ᾽ εἰδώλων φαντασίας, ut dicunt tui amici novi, qui putant etiam διανοητικὰς φαντασίας spectris Catianis excitari ; nam ne te fugiat, Catius Insuber, Ἐπικούρειος, qui nuper est mortuus, quae ille Gargettius et iam ante Democritus εἴδωλα, hic 'spectra' nominat.  his autem spectris etiam si oculi possent feriri, quod quae velis ipsa incurrunt, animus qui possit ego non video. doceas tu me oportebit, cum salvus veneris, in meane potestate sit spectrum tuum, ut, simul ac mihi conlibitum sit de te cogitare, illud occurrat ; neque solum de te, qui mihi haeres in medullis, sed si insulam Britanniam coepero cogitare, eius εἴδωλον mihi advolabit ad pectus?  sed haec posterius ; tempto enim te quo animo accipias. si enim stomachabere et moleste feres, plura dicemus postulabimusque, ex qua αἱρέσει 'VI HOMINIBVS ARMATIS' deiectus sis, in eam restituare. in hoc interdicto non solet addi 'IN HOC ANNO.' qua re si iam biennium aut triennium est cum virtuti nuntium remisisti delenitus inlecebris voluptatis, in integro res nobis erit. quamquam quicum loquor? Cum uno fortissimo viro qui, postea quam forum attigisti, nihil fecisti nisi plenissimum amplissimae dignitatis. in ista ipsa αἱρέσει metuo ne plus nervorum sit quam ego putarim, si modo eam tu probas. 'qui id tibi in mentem venit?' inquies. quia nihil habebam aliud quod scriberem ; de re p. enim nihil scribere possum ; nec enim quod sentio is libet scribere.
DXXX (F XV, 16)
TO C. CASSIUS LONGINUS (AT BRUNDISIUM)
I think you must be a little ashamed at this being the third letter inflicted on you before I have a page or a syllable from you. But I will not press you: I shall expect, or rather exact, a longer letter. For my part, if I had a messenger always at hand, I should write even three an hour. For somehow it makes you seem almost present when I write anything to you, and that not "by way of phantoms of images," as your new friends express it, 1 who hold that "mental pictures" are caused by what Catius called "spectres"—for I must remind you that Catius Insuber the Epicurean, lately dead, calls "spectres" what the famous Gargettius, and before him Democritus, used to call "images." Well, even if my eyes were capable of being struck by these "spectres," because they spontaneously run in upon them at your will, I do not see how the mind can be struck. You will be obliged to explain it to me, when you return safe and sound, whether the "spectre" of you is at my command, so as to occur to me as soon as I have taken the fancy to think about you; and not only about you, who are in my heart's core, but supposing I begin thinking about the island of Britain—will its image fly at once into my mind? But of this later on. I am just sounding you now to see how you take it. For if you are angry and annoyed, I shall say more and demand that you be restored to the sect from which you have been ejected by "violence and armed force." 2 In an injunction of this sort the words "within this year" are not usually added. Therefore, even if it is now two or three years since you divorced Virtue, 3 seduced by the charms of Pleasure, 4 it will still be open for me to do so. And yet to whom am I speaking? It is to you, the most gallant of men, who ever since you entered public life have done nothing that was not imbued to the utmost with the highest principle. In that very sect of yours I have a misgiving that there must be more stuff than I thought, if only because you accept it. "How did that come into your head?" you will say. Because I had nothing else to say. About politics I can write nothing: for I don't choose to write down my real opinions.
