Book I, section 22
De Officiis – On Duties (44 BC)
Original: (la) Non nobis solum nati sumus ortusque nostri partem patria vindicat, partem amici.

Chapter XXXIV, section 120
Orator Ad M. Brutum (46 BC)
Original: (la) Nescire autem quid ante quam natus sis acciderit, id est semper esse puerum. Quid enim est aetas hominis, nisi ea memoria rerum veterum cum superiorum aetate contexitur? ( 120 http://www.thelatinlibrary.com/cicero/orator.shtml#120)
Variant: Not to know what happened before you were born is to be a child forever. For what is the time of a man, except it be interwoven with that memory of ancient things of a superior age?

Dennis McHenry in a 2011 post at theCAMPVS.com http://thecampvs.com/2011/08/03/cicero-on-books-and-the-soul/ identified a source for the exact form of words in the essay "On the Pleasure of Reading" http://books.google.com/books?id=0YfQAAAAMAAJ&dq=cicero%20%22room%20without%20books%22%20%2B%22contemporary%20review%22&pg=PA240#v=onepage&q&f=false by Sir John Lubbock, published in The Contemporary Review, vol. 49 (1886) https://archive.org/details/contemporaryrev55unkngoog, pp. 240–51 https://archive.org/stream/contemporaryrev55unkngoog#page/n250/mode/2up, in which Lubbock wrote that "Cicero described a room without books as a body without a soul" (p. 241). The same sentence may also be found on p. 61 https://archive.org/stream/thepleasuresofli01lubbuoft#page/60/mode/2up of Lubbock's collection The Pleasures of Life. Part I. 18th edition (London and New York : Macmillan and Co. 1890) https://archive.org/details/thepleasuresofli01lubbuoft, in a lecture titled "A Song of Books". McHenry suggested that Lubbock may have had in mind the words "postea vero quam Tyrannio mihi libros disposuit mens addita videtur meis aedibus" at Cicero, Ad Atticum 4.8, which are translated by E. O. Winstedt on p. 293 https://archive.org/stream/letterstoatticus01ciceuoft#page/292/mode/2up of Cicero: Letters to Atticus I (London : William Heinemann, and New York : G. P. Putnam's Sons 1912) https://archive.org/details/letterstoatticus01ciceuoft "Since Tyrannio has arranged my books, the house seems to have acquired a soul", and by Evelyn Shuckburgh on p. 234 https://archive.org/stream/cu31924012541433#page/n283/mode/2up of The Letters of Cicero. Vol. I. B. C. 68–52 (London : George Bell and Sons 1908) https://archive.org/details/cu31924012541433 "Moreover, since Tyrannio has arranged my books for me, my house seems to have had a soul added to it" (although the Latin word " mens http://athirdway.com/glossa/?s=mens", rendered "soul" by both Winstedt and Shuckburgh, is more usually translated by the English "mind"). D. R. Shackleton Bailey in Cicero's Letters to Atticus (Harmondsworth : Penguin Books 1978), p. 162, translated "And now that Tyrannio has put my books straight, my house seems to have woken to life".

Variant: Ut conclave sine libris ita corpus sine anima" A room without books is like a body without a soul

To Varro, in Ad Familiares IX, 4
Original: (la) Si hortum in bibliotheca habes, nihil deerit.

De Re Publica [Of The Republic], Book III Section 22; as translated by Francis Barham
Variant translations:
True law is right reason in agreement with nature; it is of universal application, unchanging and everlasting; it summons to duty by its commands, and averts from wrongdoing by its prohibitions. And it does not lay its commands or prohibitions upon good men in vain, though neither have any effect on the wicked. It is a sin to try to alter this law, nor is it allowable to attempt to repeal any part of it, and it is impossible to abolish it entirely. We cannot be freed from its obligations by senate or people, and we need not look outside ourselves for an expounder or interpreter of it. And there will not be different laws at Rome and at Athens, or different laws now and in the future, but one eternal and unchangeable law will be valid for all nations and all times, and there will be one master and ruler, that is, God, over us all, for he is the author of this law, its promulgator, and its enforcing judge. Whoever is disobedient is fleeing from himself and denying his human nature, and by reason of this very fact he will suffer the worst penalties, even if he escapes what is commonly considered punishment.
As translated by Clinton W. Keyes (1928)<!-- ; in De Re Publica, De Legibus (1943), p. 211 -->
Original: (la) Est quidem vera lex recta ratio naturae congruens, diffusa in omnes, constans, sempiterna, quae vocet ad officium iubendo, vetando a fraude deterreat; quae tamen neque probos frustra iubet aut vetat nec improbos iubendo aut vetando movet. Huic legi nec obrogari fas est neque derogari ex hac aliquid licet neque tota abrogari potest, nec vero aut per senatum aut per populum solvi hac lege possumus, neque est quaerendus explanator aut interpres eius alius, nec erit alia lex Romae, alia Athenis, alia nunc, alia posthac, sed et omnes gentes et omni tempore una lex et sempiterna et immutabilis continebit, unusque erit communis quasi magister et imperator omnium deus, ille legis huius inventor, disceptator, lator; cui qui non parebit, ipse se fugiet ac naturam hominis aspernatus hoc ipso luet maximas poenas, etiamsi cetera supplicia, quae putantur, effugerit.
Context: There is a true law, a right reason, conformable to nature, universal, unchangeable, eternal, whose commands urge us to duty, and whose prohibitions restrain us from evil. Whether it enjoins or forbids, the good respect its injunctions, and the wicked treat them with indifference. This law cannot be contradicted by any other law, and is not liable either to derogation or abrogation. Neither the senate nor the people can give us any dispensation for not obeying this universal law of justice. It needs no other expositor and interpreter than our own conscience. It is not one thing at Rome and another at Athens; one thing to–day and another to–morrow; but in all times and nations this universal law must for ever reign, eternal and imperishable. It is the sovereign master and emperor of all beings. God himself is its author,—its promulgator,—its enforcer. He who obeys it not, flies from himself, and does violence to the very nature of man. For his crime he must endure the severest penalties hereafter, even if he avoid the usual misfortunes of the present life.

Cato Maior de Senectute – On Old Age (44 BC)
Original: (la) Itaque adulescentes mihi mori sic videntur, ut cum aquae multitudine flammae vis opprimitur, senes autem sic, ut cum sua sponte nulla adhibita vi consumptus ignis exstinguitur; et quasi poma ex arboribus, cruda si sunt, vix evelluntur, si matura et cocta, decidunt, sic vitam adulescentibus vis aufert, senibus maturitas; quae quidem mihi tam iucunda est, ut, quo propius ad mortem accedam, quasi terram videre videar aliquandoque in portum ex longa navigatione esse venturus.
Context: When the young die I am reminded of a strong flame extinguished by a torrent; but when old men die it is as if a fire had gone out without the use of force and of its own accord, after the fuel had been consumed; and, just as apples when they are green are with difficulty plucked from the tree, but when ripe and mellow fall of themselves, so, with the young, death comes as a result of force, while with the old it is the result of ripeness. To me, indeed, the thought of this "ripeness" for death is so pleasant, that the nearer I approach death the more I feel like one who is in sight of land at last and is about to anchor in his home port after a long voyage.

Book V, chapter 15, section 43; translated by Andrew P. Peabody
Tusculanae Disputationes – Tusculan Disputations (45 BC)
Original: (la) Atque cum perturbationes animi miseriam, sedationes autem vitam efficiant beatam, duplexque ratio perturbationis sit, quod aegritudo et metus in malis opinatis, in bonorum autem errore laetitia gestiens libidoque versetur, quae omnia cum consilio et ratione pugnent, his tu tam gravibus concitationibus tamque ipsis inter se dissentientibus atque distractis quem vacuum solutum liberum videris, hunc dubitabis beatum dicere? atqui sapiens semper ita adfectus est; semper igitur sapiens beatus est.
Context: Now since perturbations of mind create misery, while quietness of mind makes life happy, and since there are two kinds of perturbations, grief and fear having their scope in imagined evils, inordinate joy and desire in mistaken notions of the good, all being repugnant to wise counsel and reason, will you hesitate to call him happy whom you see relieved, released, free from these excitements so oppressive, and so at variance and divided among themselves? Indeed one thus disposed is always happy. Therefore the wise man is always happy.

Philippica II, Sections 5 & 6, as translated by Michael Grant, in Cicero : Selected Works (1960), Part One: Against Tyranny; Ch. 3: Attack on an Enemy of Freedom: The Second Philippic against Antony, p. 104
Variant translation:
What kind of favour is it to abstain from doing evil?
Philippicae – Philippics (44 BC)
Original: (la) Quod est aliud, patres conscripti, beneficium latronum, nisi ut commemorare possint iis se dedisse vitam, quibus non ademerint? Quod si esset beneficium, numquam, qui illum interfecerunt, a quo erant conservati, quos tu clarissimos viros soles appellare, tantam essent gloriam consecuti. Quale autem beneficium est, quod te abstinueris nefario scelere? Qua in re non tam iucundum mihi videri debuit non interfectum me a te quam miserum te id impune facere potuisse.
Sed sit beneficium, quandoquidem maius accipi a latrone nullum potuit; in quo potes me dicere ingratum? An de interitu rei publicae queri non debui, ne in te ingratus viderer?
Context: Nevertheless, let us imagine that you could have killed me. That, Senators, is what a favour from gangsters amounts to. They refrain from murdering someone; then they boast that they have spared him! If that is a true favour, then those who killed Caesar, after he had spared them, would never have been regarded as so glorious — and they are men whom you yourself habitually describe as noble. But the mere abstention from a dreadful crime is surely no sort of favour. In the situation in which this "favour" placed me, my dominant feelings ought not to have been pleasure because you did not kill me, but sorrow because you could have done so with impunity.
However, let us even assume that it was a favour; at any rate the best favour that a gangster could confer. Still, in what respect can you call me ungrateful? Were my protests against the downfall of our country wrong, because you might think they showed ingratitude?

Book I, section 42; Translation by C.D. Yonge)
De Legibus (On the Laws)
Original: (la) Est enim unum ius quo deuincta est hominum societas et quod lex constituit una, quae lex est recta ratio imperandi atque prohibendi. Quam qui ignorat, is est iniustus, siue est illa scripta uspiam siue nusquam.
Context: For there is but one essential justice which cements society, and one law which establishes this justice. This law is right reason, which is the true rule of all commandments and prohibitions. Whoever neglects this law, whether written or unwritten, is necessarily unjust and wicked.

Book II, section 7; translation by Walter Miller
De Officiis – On Duties (44 BC)
Original: (la) Multorum autem odiis nullas opes posse obsistere, si antea fuit ignotum, nuper est cognitum. Nec vero huius tyranni solum, quem armis oppressa pertulit civitas ac paret cum maxime mortuo interitus declarat, quantum odium hominum valeat ad pestem, sed reliquorum similes exitus tyrannorum, quorum haud fere quisquam talem interitum effugit. Malus enim est custos diuturnitatis metus contraque benivolentia fidelis vel ad perpetuitatem.
Context: And we recently discovered, if it was not known before, that no amount of power can withstand the hatred of the many. The death of this tyrant (Julius Caesar), whose yoke the state endured under the constraint of armed force and whom it still obeys more humbly than ever, though he is dead, illustrates the deadly effects of popular hatred; and the same lesson is taught by the similar fate of all other despots, of whom practically no one has ever escaped such a death. For fear is but a poor safeguard of lasting power; while affection, on the other hand, may be trusted to keep it safe for ever.
