Graecia quam Troiae divino numine vexit, Omniaque e latis rerum vestigia terris. Velut ego nunc moveor. An quae de prudentia, de cognitione rerum, de coniunctione generis humani, quaeque ab eisdem de temperantia, de modestia, de magnitudine animi, de omni honestate dicuntur? Et tamen quid attinet luxuriosis ullam exceptionem dari aut fingere aliquos, qui, cum luxuriose viverent, a summo philosopho non reprehenderentur eo nomine dumtaxat, cetera caverent?

Uterque enim summo bono fruitur, id est voluptate. Duo Reges: constructio interrete. Nam prius a se poterit quisque discedere quam appetitum earum rerum, quae sibi conducant, amittere. Confecta res esset. Ea enim omnia, quae illi bona dicerent, praeposita esse, non bona, itemque illa, quae in corpore excellerent, stulte antiquos dixisse per se esse expetenda; At vero Callipho et post eum Diodorus, cum is alter voluptatem adamavisset, alter vacuitatem doloris, neuter honestate carere potuit, quae est a nostris laudata maxime.

Estne, quaeso, inquam, sitienti in bibendo voluptas?

Hoc dictum in una re latissime patet, ut in omnibus factis re, non teste moveamur. Sed ego in hoc resisto; Iam id ipsum absurdum, maximum malum neglegi. Quid ad utilitatem tantae pecuniae? Prioris generis est docilitas, memoria; Nunc vides, quid faciat. Nec vero umquam summum bonum assequi quisquam posset, si omnia illa, quae sunt extra, quamquam expetenda, summo bono continerentur. Hoc dictum in una re latissime patet, ut in omnibus factis re, non teste moveamur. Haec qui audierit, ut ridere non curet, discedet tamen nihilo firmior ad dolorem ferendum, quam venerat. Illa autem, morbum, egestatem, dolorem, non appello m a l a, sed, si libet, r e i e c t a n e a.

Verum tamen cum de rebus grandioribus dicas, ipsae res verba
rapiunt;

Quid, si non modo utilitatem tibi nullam afferet, sed
iacturae rei familiaris erunt faciendae, labores
suscipiendi, adeundum vitae periculum?

Ut aliquid scire se gaudeant? Respondebo me non quaerere, inquam, hoc tempore quid virtus efficere possit, sed quid constanter dicatur, quid ipsum a se dissentiat. Non igitur bene. Id enim ille summum bonum eu)qumi/an et saepe a)qambi/an appellat, id est animum terrore liberum. Tollenda est atque extrahenda radicitus. At vero Callipho et post eum Diodorus, cum is alter voluptatem adamavisset, alter vacuitatem doloris, neuter honestate carere potuit, quae est a nostris laudata maxime. Qui-vere falsone, quaerere mittimus-dicitur oculis se privasse; At vero Callipho et post eum Diodorus, cum is alter voluptatem adamavisset, alter vacuitatem doloris, neuter honestate carere potuit, quae est a nostris laudata maxime. Et hanc quidem primam exigam a te operam, ut audias me quae a te dicta sunt refellentem. Nam cum Academicis incerta luctatio est, qui nihil affirmant et quasi desperata cognitione certi id sequi volunt, quodcumque veri simile videatur. Ita prorsus, inquam; Ut pulsi recurrant? Sed erat aequius Triarium aliquid de dissensione nostra iudicare. Si longus, levis.

Quis est, qui non oderit libidinosam, protervam adolescentiam?
Iam enim adesse poterit.
Haec dicuntur inconstantissime.
Quem Tiberina descensio festo illo die tanto gaudio affecit, quanto L.
Quae in controversiam veniunt, de iis, si placet, disseramus.
Quamquam ab iis philosophiam et omnes ingenuas disciplinas habemus;

Praeteritis, inquit, gaudeo. Atque omnia quidem scire, cuiuscumque modi sint, cupere curiosorum, duci vero maiorum rerum contemplatione ad cupiditatem scientiae summorum virorum est putandum. Hunc igitur finem illi tenuerunt, quodque ego pluribus verbis, illi brevius secundum naturam vivere, hoc iis bonorum videbatur extremum. Ut enim consuetudo loquitur, id solum dicitur honestum, quod est populari fama gloriosum. Moriatur, inquit. Sed hoc summum bonum, quod tertia significatione intellegitur, eaque vita, quae ex summo bono degitur, quia coniuncta ei virtus est. Idque quo magis quidam ita faciunt, ut iure etiam reprehendantur, hoc magis intellegendum est haec ipsa nimia in quibusdam futura non fuisse, nisi quaedam essent modica natura. Ita fit illa conclusio non solum vera, sed ita perspicua, ut dialectici ne rationem quidem reddi putent oportere: si illud, hoc; Quae enim constituta sunt prima naturae, ad ea si voluptas accesserit, unum aliquod accesserit commodum corporis neque eam constitutionem summi boni, quae est proposta, mutaverit. Hunc ipsum Zenonis aiunt esse finem declarantem illud, quod a te dictum est, convenienter naturae vivere. Quo igitur, inquit, modo? Nam voluptatis causa facere omnia, cum, etiamsi nihil consequamur, tamen ipsum illud consilium ita faciendi per se expetendum et honestum et solum bonum sit, nemo dixit.

Quid enim mihi potest esse optatius quam cum Catone, omnium virtutum auctore, de virtutibus disputare?

Non est igitur summum malum dolor. Quibus expositis facilis est coniectura ea maxime esse expetenda ex nostris, quae plurimum habent dignitatis, ut optimae cuiusque partis, quae per se expetatur, virtus sit expetenda maxime. Iam in altera philosophiae parte. Itaque ab iis constitutio illa prima naturae, a qua tu, quoque ordiebare, his prope verbis exponitur: Omnis natura vult esse conservatrix sui, ut et salva sit et in genere conservetur suo. Inde sermone vario sex illa a Dipylo stadia confecimus. Rationis enim perfectio est virtus; Quis istud possit, inquit, negare? Istam voluptatem perpetuam quis potest praestare sapienti? Quanta autem ab illis varietas argumentorum ratione concludentium eorumque cum captiosis interrogationibus dissimilitudo! Quid, quod plurimis locis quasi denuntiant, ut neque sensuum fidem sine ratione nec rationis sensibus exquiramus? Sin autem reliqua appetenda sunt, cur, quod est ultimum rerum appetendarum, id non aut ex omnium earum aut ex plurimarum et maximarum appetitione concluditur? Quamquam non negatis nos intellegere quid sit voluptas, sed quid ille dicat. Hic cum uterque me intueretur seseque ad audiendum significarent paratos, Primum, inquam, deprecor, ne me tamquam philosophum putetis scholam vobis aliquam explicaturum, quod ne in ipsis quidem philosophis magnopere umquam probavi.

]]> Ratio quidem vestra sic cogit.

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ex quo intellegitur idem illud, solum bonum esse, quod honestum sit, idque esse beate vivere: honeste, id est cum virtute, vivere. Stoici restant, ei quidem non unam aliquam aut alteram rem a nobis, sed totam ad se nostram philosophiam transtulerunt.

Qui mos cum a posterioribus non esset retentus, Arcesilas eum revocavit instituitque ut ii, qui se audire vellent, non de se quaererent, sed ipsi dicerent, quid sentirent; Praeclare hoc quidem. Duo Reges: constructio interrete. Haec mirabilia videri intellego, sed cum certe superiora firma ac vera sint, his autem ea consentanea et consequentia, ne de horum quidem est veritate dubitandum. Aut etiam, ut vestitum, sic sententiam habeas aliam domesticam, aliam forensem, ut in fronte ostentatio sit, intus veritas occultetur? Quoniamque in iis rebus, quae neque in virtutibus sunt neque in vitiis, est tamen quiddam, quod usui possit esse, tollendum id non est. Ut aliquid scire se gaudeant? Nam voluptatis causa facere omnia, cum, etiamsi nihil consequamur, tamen ipsum illud consilium ita faciendi per se expetendum et honestum et solum bonum sit, nemo dixit. Esto, fecerit, si ita vis, Torquatus propter suas utilitatesmalo enim dicere quam voluptates, in tanto praesertim viro-, num etiam eius collega P. Quae contraria sunt his, malane? An quae de prudentia, de cognitione rerum, de coniunctione generis humani, quaeque ab eisdem de temperantia, de modestia, de magnitudine animi, de omni honestate dicuntur?

Epicurei num desistunt de isdem, de quibus et ab Epicuro
scriptum est et ab antiquis, ad arbitrium suum scribere?

Qui autem esse poteris, nisi te amor ipse ceperit?

Ad eos igitur converte te, quaeso. Quae tamen a te agetur non melior, quam illae sunt, quas interdum optines. An obliviscimur, quantopere in audiendo in legendoque moveamur, cum pie, cum amice, cum magno animo aliquid factum cognoscimus? Tubulo putas dicere? Sed et illum, quem nominavi, et ceteros sophistas, ut e Platone intellegi potest, lusos videmus a Socrate. Quos ille, di inmortales, cum omnes artus ardere viderentur, cruciatus perferebat! nec tamen miser esse, quia summum id malum non erat, tantum modo laboriosus videbatur; Dolere malum est: in crucem qui agitur, beatus esse non potest. Quae in controversiam veniunt, de iis, si placet, disseramus. Et homini, qui ceteris animantibus plurimum praestat, praecipue a natura nihil datum esse dicemus? Non dolere, inquam, istud quam vim habeat postea videro; Possumusne hic scire qualis sit, nisi contulerimus inter nos, cum finem bonorum dixerimus, quid finis, quid etiam sit ipsum bonum? Ut enim, inquit, gubernator aeque peccat, si palearum navem evertit et si auri, item aeque peccat, qui parentem et qui servum iniuria verberat.

Me quidem ad altiorem memoriam Oedipodis huc venientis et illo mollissimo carmine quaenam essent ipsa haec loca requirentis species quaedam commovit, inaniter scilicet, sed commovit tamen. Illa tamen simplicia, vestra versuta. Immo alio genere; Itaque non discedit ab eorum curatione, quibus praeposita vitam omnem debet gubernare, ut mirari satis istorum inconstantiam non possim. Perfecto enim et concluso neque virtutibus neque amicitiis usquam locum esse, si ad voluptatem omnia referantur, nihil praeterea est magnopere dicendum. Huc et illuc, Torquate, vos versetis licet, nihil in hac praeclara epistula scriptum ab Epicuro congruens et conveniens decretis eius reperietis. Quoniam enim natura suis omnibus expleri partibus vult, hunc statum corporis per se ipsum expetit, qui est maxime e natura, quae tota perturbatur, si aut aegrum corpus est aut dolet aut, caret viribus. Aut, si nihil malum, nisi quod turpe, inhonestum, indecorum, pravum, flagitiosum, foedum-ut hoc quoque pluribus nominibus insigne faciamus-, quid praeterea dices esse fugiendum?

Nam si quae sunt aliae, falsum est omnis animi voluptates esse e corporis societate. Est enim natura sic generata vis hominis, ut ad omnem virtutem percipiendam facta videatur, ob eamque causam parvi virtutum simulacris, quarum in se habent semina, sine doctrina moventur; In quibus hoc primum est in quo admirer, cur in gravissimis rebus non delectet eos sermo patrius, cum idem fabellas Latinas ad verbum e Graecis expressas non inviti legant. Et si turpitudinem fugimus in statu et motu corporis, quid est cur pulchritudinem non sequamur? Id enim natura desiderat. Poterat autem inpune; Cumque eorum utrumque per se expetendum esse dixissent, virtutes quoque utriusque eorum per se expetendas esse dicebant, et cum animum infinita quadam laude anteponerent corpori, virtutes quoque animi bonis corporis anteponebant.

Nam interdum nimis etiam novit, quippe qui testificetur ne intellegere quidem se posse ubi sit aut quod sit ullum bonum praeter illud, quod cibo et potione et aurium delectatione et obscena voluptate capiatur.

Easdemne res? Si in ipso corpore multa voluptati praeponenda sunt, ut vires, valitudo, velocitas, pulchritudo, quid tandem in animis censes? In motu et in statu corporis nihil inest, quod animadvertendum esse ipsa natura iudicet? Nos beatam vitam non depulsione mali, sed adeptione boni iudicemus, nec eam cessando, sive gaudentem, ut Aristippus, sive non dolentem, ut hic, sed agendo aliquid considerandove quaeramus. In schola desinis. Iure igitur gravissimi philosophi initium summi boni a natura petiverunt et illum appetitum rerum ad naturam accommodatarum ingeneratum putaverunt omnibus, quia continentur ea commendatione naturae, qua se ipsi diligunt. Effluit igitur voluptas corporis et prima quaeque avolat saepiusque relinquit causam paenitendi quam recordandi. Reperiam multos, vel innumerabilis potius, non tam curiosos nec tam molestos, quam vos estis, quibus, quid velim, facile persuadeam. Aut etiam, ut vestitum, sic sententiam habeas aliam domesticam, aliam forensem, ut in fronte ostentatio sit, intus veritas occultetur? Hoc loco tenere se Triarius non potuit. Quem quidem locum comit multa venustate et omni sale idem Lucilius, apud quem praeclare Scaevola: Graecum te, Albuci, quam Romanum atque Sabinum, municipem Ponti, Tritani, centurionum, praeclarorum hominum ac primorum signiferumque, maluisti dici. Tum ille: Finem, inquit, interrogandi, si videtur, quod quidem ego a principio ita me malle dixeram hoc ipsum providens, dialecticas captiones. Equidem, sed audistine modo de Carneade? Esse tantam vim virtutis tantamque, ut ita dicam, auctoritatem honestatis, ut reliqua non illa quidem nulla, sed ita parva sint, ut nulla esse videantur. Sed ad bona praeterita redeamus.

An eiusdem modi?: Huius ego nunc auctoritatem sequens idem faciam.
Si longus, levis.: Itaque e contrario moderati aequabilesque habitus, affectiones ususque corporis apti esse ad naturam videntur.
Erat enim Polemonis.: Nam adhuc, meo fortasse vitio, quid ego quaeram non perspicis.
Primum divisit ineleganter;: Ita fit beatae vitae domina fortuna, quam Epicurus ait exiguam intervenire sapienti.
