The Academic Questions, Treatise De Finibus, and Tusculan Disputations, of M.T. Cicero, With a Sketch of the Greek Philosophers Mentioned by · Marcus Tullius Cicero
CONTENTS
_Diagoras_ was a native of Melos, and a pupil of Democritus, and flourished about B.C. 435. He is remarkable as having been regarded by all antiquity as an Atheist. In his youth he had some reputation as a lyric poet; so that he is sometimes classed with Pindar, Simonides, and Bacchylides. Aristophanes, in the Clouds, alludes to him where he calls Socrates “the Melian;” not that he was so, but he means to hint that Socrates was an atheist as well as the Melian Diagoras. He lived at Athens for many years till B.C. 411, when he fled from a prosecution instituted against him for impiety, according to Diodorus, but probably for some offence of a political nature; perhaps connected with the mutilation of the Hermæ. That he was an atheist, however, appears to have been quite untrue. Like Socrates, he took new and peculiar views respecting the Gods and their worship; and seems to have ridiculed the honours paid to their statues, and the common notions which were entertained of their actions and conduct. (See De Nat. Deor. iii. 37.) He is said also to have attacked objects held in the greatest veneration at Athens, such as the Eleusinian Mysteries, and to have dissuaded people from being initiated into them. He appears also, in his theories on the divine nature, to have substituted in some degree the active powers of nature for the activity of the Gods. In his own conduct he was a man of strict morality and virtue. He died at Corinth before the end of the century.
_Protagoras_ was a native of Abdera; the exact time of his birth is unknown, but he was a little older than Socrates. He was the first person who gave himself the title of σοφιστὴς, and taught for pay. He came to Athens early in life, and gave to the settlers who left it for Thurium, B.C. 445, a code of laws, or perhaps adapted the old laws of Charondas to their use. He was a friend of Pericles. After some time he was impeached for impiety in saying, That respecting the Gods he did not know whether they existed or not; and banished from Athens (see De Nat. Deor. i. 23). He was a very prolific author: his most peculiar doctrines excited Plato to write the Theætetus to oppose them. His fundamental principle was, that everything is motion, and that that is the efficient cause of everything; that nothing _exists_, but that everything is continually _coming into existence_. He divided motion (besides numerous subordinate divisions) into active and passive; though he did not consider either of these characteristics as permanent. From the concurrence of two such motions he taught that sensations and perceptions arose, according to the rapidity of the motion. Therefore he said that there is or exists for each individual, only that of which he has a sensation or perception; and that as sensation, like its objects, is engaged in a perpetual change of motion, opposite assertions might exist according to the difference of the perception respecting such object. Moral worth he attributed to taking pleasure in the beautiful; and virtue he referred to a certain sense of shame implanted in man by nature; and to a certain conscious feeling of justice, which secures the bonds of connexion in private and political life.
_Socrates_, the son of Sophroniscus, a statuary, and Phænarete, a midwife, was born B.C. 468. He lived all his life at Athens, serving indeed as a soldier at Potidæa, Amphipolis, and in the battle of Delium; but with these exceptions he never left the city; where he lived as a teacher of philosophy; not, however, founding a school or giving lectures, but frequenting the market-place and all other places of public resort, talking with every one who chose to address him, and putting questions to every one of every rank and profession, so that Grote calls him “a public talker for instruction.” He believed himself to have a special religious mission from the Gods to bring his countrymen to knowledge and virtue. He was at last impeached before the legal tribunals, on the ground of “corrupting the youth of the city, and not worshipping the Gods whom the city worshipped;” and disdaining to defend himself, or rather making a justificatory defence of such a character as to exasperate the judges, he was condemned to death, and executed by having hemlock administered to him, B.C. 399.
From his disciples Plato and Xenophon we have a very full account of his habits and doctrines; though it has been much disputed which of the two is to be considered as giving the most accurate description of his opinions. As a young man he had been to a certain extent a pupil of Archelaus (the disciple of Anaxagoras), and derived his fondness for the dialectic style of argument from Zeno the Eleatic, the favourite Pupil of Parmenides. He differed, however, from all preceding philosophers in discarding and excluding wholly from his studies all the abstruse sciences, and limiting his philosophy to those practical points which could have influence on human conduct. “He himself was always conversing about the affairs of men,” is the description given of him by Xenophon. Astronomy he pronounced to be one of the divine mysteries which it was impossible to understand and madness to investigate; all that man wanted was to know enough of the heavenly bodies to serve as an index to the change of seasons and as guides for voyages, etc.; and that knowledge might, he said, easily be obtained from pilots and watchmen. Geometry he reduced to its literal meaning of land-measuring, useful to enable one to act with judgment in the purchase or sale of land; but he looked with great contempt on the study of complicated diagrams and mathematical problems. As to general natural philosophy, he wholly discarded it; asking whether those who professed to apply themselves to that study knew _human_ affairs so well as to have time to spare for _divine_; was it that they thought that they could influence the winds, rain, and seasons, or did they desire nothing but the gratification of an idle curiosity? Men should recollect how much the wisest of them who have attempted to prosecute these investigations differ from one another, and how totally opposite and contradictory their opinions are.
Socrates, then, looked at all knowledge from the point of view of human practice. He first, as Cicero says, (Tusc. Dis. v. 4,) “called philosophy down from heaven and established it in the cities, introduced it even into private houses, and compelled it to investigate life, and manners, and what was good and evil among men.” He was the first man who turned his thoughts and discussions distinctly to the subject of Ethics. Deeply imbued with sincere religious feeling, and believing himself to be under the peculiar guidance of the Gods, who at all times admonished him by a divine warning voice when he was in danger of doing anything unwise, inexpedient, or improper, he believed that the Gods constantly manifested their love of and care for all men in the most essential manner, in replying through oracles, and sending them information by sacrificial signs or prodigies, in cases of great difficulty; and he had no doubt that if a man were diligent in learning all that the Gods permitted to be learnt, and if besides he was assiduous in paying pious court to them and in soliciting special information by way of prophecy, they would be gracious to him and signify their purposes to him.
Such then being the capacity of man for wisdom and virtue, his object was to impart that wisdom to them; and the first step necessary, he considered to be eradicating one great fault which was a barrier to all improvement. This fault he described as “the conceit of knowledge without the reality.” His friend and admirer Chærephon had consulted the oracle at Delphi as to whether any man was wiser than Socrates; to which the priestess replied that no other man was wiser. Socrates affirms that he was greatly disturbed at hearing this declaration from so infallible an authority; till after conversing with politicians, and orators, and poets, and men of all classes, he discovered not only that they were destitute of wisdom, but that they believed themselves to be possessed of it; so that he was wiser than they, though wholly ignorant, inasmuch as he was conscious of his own ignorance. He therefore considered his most important duty to be to convince men of their ignorance, and to excite them to remedy it, as the indispensable preliminary to virtue; for virtue he defined as doing a thing well, after having learnt it and practised it by the rational and proper means; and whoever performed his duties best, whether he was a ruler of a state or a husbandman, was the best and most useful man and the most beloved by the Gods.
And if his objects were new, his method was no less so. He was the parent of dialectics and logic. Aristotle says, “To Socrates we may unquestionably assign two novelties—inductive discourses, and the definitions of general terms.” Without any predecessor to copy, Socrates fell as it were instinctively into that which Aristotle describes as the double tract of the dialectic process, breaking up the one into the many, and recombining the many into the one; though the latter or synthetical process he did not often perform himself, but strove to stimulate his hearer’s mind so as to enable him to do it for himself. The fault of the Socratic theory is well remarked by Grote to be, that while he resolved all virtue into knowledge or wisdom, and all vice into ignorance or folly, he omitted to notice what is not less essential to virtue, the proper condition of the passions, desires, &c., and limited his views too exclusively to the intellect; still while laying down a theory which is too narrow, he escaped the erroneous consequences of it by a partial inconsistency. For no one ever insisted more emphatically on the necessity of control over the passions and appetites, of enforcing good habits, and on the value of that state of the sentiments and emotions which such a course tended to form. He constantly pointed out that the chief pleasures were such as inevitably arise from the performance of one’s duty, and that as to happiness, a very moderate degree of good fortune is sufficient as to external things, provided the internal man be properly disciplined.
Grote remarks further, (and this remark is particularly worth remembering in the reading of Cicero’s philosophical works,) that “Arcesilaus and the New Academy thought that they were following the example of Socrates, (and Cicero appears to have thought so too,) when they reasoned against everything, and laid it down as a system, that against every affirmative position an equal force of negative argument could be brought as a counterpoise: now this view of Socrates is, in my judgment, not only partial, but incorrect. He entertained no such doubts of the powers of the mind to attain certainty. About physics he thought man could know nothing; but respecting the topics which concern man and society, this was the field which the Gods had expressly assigned, not merely to human practice, but to human study and knowledge; and he thought that every man, not only might know these things, but ought to know them; that he could not possibly act well unless he did know them; and that it was his imperative duty to learn them as he would learn a profession, otherwise he was nothing better than a slave, unfit to be trusted as a free and accountable being. He was possessed by the truly Baconian idea, that the power of steady moral action depended upon, and was limited by, the rational comprehension of moral ends and means.”
The system, then, of Socrates was animated by the truest spirit of positive science, and formed an indispensable precursor to its attainment. And we may form some estimate of his worth and genius if we recollect, that while the systems and speculations of other ancient philosophers serve only as curiosities to make us wonder, or as beacons to warn us into what absurdities the ablest men may fall, the principles and the system of Socrates and his followers, and of that school alone, exercise to this day an important influence on all human argument and speculation. _Aristippus_ (whom we will consider before Plato, that Aristotle may follow Plato more immediately) came when a young man to Athens, for the express purpose of becoming acquainted with Socrates, with whom he remained almost till his death. He was, however, very different from his master, being a person of most luxurious and sensual habits. He was also the first of Socrates’ disciples who took money for teaching. He was the founder of the Cyrenaic school of philosophy, which followed Socrates in limiting all philosophical inquiries to ethics; though under this name they comprehended a more varied range of subjects than Socrates did, inasmuch as one of the parts into which they divided philosophy, referred to the feelings; another to causes, which is rather a branch of physics; and a third to proofs, which is clearly connected with logic.
He pronounced pleasure to be the chief good, and pain the chief evil; but he denied that either of these was a mere negative inactive state, considering them, on the contrary, both to be motions of the soul,—pain a violent, and pleasure a moderate one. As to actions, he asserted that they were all morally indifferent, that men should only look to their results, and that law and custom are the only authorities which make an action either good or bad. Whatever conduces to pleasure, he thought virtue; in which he agreed with Socrates that the mind has the principal share. _Plato_, the greatest of all the disciples of Socrates, was the son of Ariston and Perictione, and was born probably in the year B.C. 428, and descended, on the side of his father, from Codrus, and on his mother’s side related to Solon. At the age of twenty, he became a constant attendant of Socrates, and lived at Athens till his death. After this event, in consequence of the unpopularity of the very name of his master, he retired to Megara, and subsequently to Sicily. He is said also to have been at some part of his life, after the death of Socrates, a great traveller. About twelve years after the death of Socrates he returned to Athens, and began to teach in the Academy, partly by dialogue, and partly, probably, by connected lectures. He taught gratuitously; and besides Speusippus, Xenocrates, Aristotle, Heraclides Ponticus, and others, who were devoted solely to philosophical studies, he is said to have occasionally numbered Chabrias, Iphicrates, Timotheus, Phocion, Isocrates, and (by some) Demosthenes among his hearers. He died at a great age, B.C. 347.
His works have come down to us in a more complete form than those of any other ancient author who was equally voluminous; and from them we get a clear idea of the principal doctrines which he inculcated on his followers. Like Socrates, he was penetrated with the idea, that knowledge and wisdom were the things most necessary to man, and the greatest goods assigned to him by God. Wisdom he looked on as the great purifier of the soul; and as any approach to wisdom presupposes an original communion with _Being_, properly so called, this communion also presupposes the divine nature, and consequent immortality of the soul, his doctrine respecting which was of a much purer and loftier character than the usual theology of the ancients. Believing that the world also had a soul, he considered the human soul as similar to it in nature, and free from all liability to death, in spite of its being bound up with the appetites, in consequence of its connexion with the body, and as preserving power and consciousness after its separation from the body. What he believed, however, to be its condition after death is far less certain, as his ideas on this subject are expressed in a mythical form.
The chief point, however, to which Plato directed his attention, was ethics, which, especially in his system, are closely connected with politics. He devotes the Protagoras, and several shorter dialogues, to refute the sensual and selfish theories of some of his predecessors, in order to adopt a more scientific treatment of the subject; and in these dialogues he urges that neither happiness nor virtue are attainable by the indulgence of our desires, but that men must bring these into proper restraint, if they are desirous of either. He supposes an inward harmony, the preservation of which is pleasure, while its disturbance is pain; and as pleasure is always dependent on the activity from which it springs, the more this activity is elevated the purer the pleasure becomes. Virtue he considered the fitness of the soul for the operations that are proper to it; and it manifests itself by means of its inward harmony, beauty, and health. Different phases of virtue are distinguishable so far as the soul is not pure spirit, but just as the spirit should rule both the other elements of the soul, so also should wisdom, as the inner development of the spirit, rule the other virtues.
Politics he considered an inseparable part of ethics, and the state as the copy of a well-regulated individual life: from the three different activities of the soul he deduced the three main elements of the state, likening the working class to the appetitive element of the soul, both of which equally require to be kept under control; the military order, which answered, in his idea, to the emotive element, ought to develop itself in thorough dependence on the reason; and from that the governing order, answering to the rational faculty, must proceed. The right of passing from a subordinate to a dominant position must depend on the individual capacity and ability for raising itself. But from the difficulties of realizing his theories, he renounces this absolute separation of ranks in his book on Laws, limits the power of the governors, attempts to reconcile freedom with unity and reason, and to mingle monarchy with democracy. With respect to his theology, he appears to have agreed entirely with Socrates.
_Aristotle_ was born at Stageira, B.C. 384. His father, Nicomachus, was physician to Amyntas II., king of Macedon. At the age of seventeen he went to Athens, in hopes to become a pupil of Plato; but Plato was in Sicily, and did not return for three years, which time Aristotle applied to severe study, and to cultivating the friendship of Heraclides Ponticus. When Plato returned, he soon distinguished him above all his other pupils. He remained at Athens twenty years, maintaining, however, his connexion with Macedonia; but on the death of Plato, B.C. 347, which happened while Aristotle was absent in Macedonia on an embassy, he quitted Athens, thinking, perhaps, that travelling was necessary to complete his education. After a short period, he accepted an invitation from Philip to superintend the education of Alexander. He remained in Macedonia till B.C. 335, when he returned to Athens, where he found Xenocrates had succeeded Speusippus as the head of the Academy. Here the Lyceum was appropriated to him, in the shady walks (περίπατοι) of which he delivered his lectures to a number of eminent scholars who flocked around him. From these walks the name of Peripatetic was given to the School which he subsequently established. Like several others of the Greek philosophers, he had a select body of pupils, to whom he delivered his esoteric doctrines; and a larger, more promiscuous, and less accomplished company, to whom he delivered his exoteric lectures on less abstruse subjects. When he had resided thirteen years at Athens, he found himself threatened with a prosecution for impiety, and fled to Chalcis, in Eubœa, and died soon after, B.C. 322.
His learning was immense, and his most voluminous writings embraced almost every subject conceivable; but only a very small portion of them has come down to us. Cicero, however, alludes to him only as a moral philosopher, and occasionally as a natural historian; so that it may be sufficient here for us to confine our view of him to his teaching on the Practical Sciences; his Ethics, too, being one of his works which has come down to us entire. God he considered to be the highest and purest energy of eternal intellect,—an absolute principle,—the highest reason, the object of whose thought is himself; expanding and declaring, in a more profound manner, the νοῦς of Anaxagoras. With respect to man, the object of all action, he taught, was happiness: and this happiness he defines to be an energy of the soul (or of life) according to virtue, existing by and for itself. Virtue, again, he subdivided into moral and intellectual, according to the distinction between the reasoning faculty and that quality in the soul which obeys reason. Again, moral virtue is the proper medium between excess and deficiency, and can only be acquired by practice; intellectual virtue can be taught; and by the constant practice of moral virtue a man becomes virtuous, but he can only practise it by a resolute determination to do so. Virtue, therefore, is defined further as a habit accompanied by, or arising out of, deliberate choice, and based upon free and conscious action. From these principles, Aristotle is led to take a wider view of virtue than other philosophers: he includes friendship under this head, as one of the very greatest virtues, and a principal means for a steady continuance in all virtue; and as the unrestricted exercise of each species of activity directed towards the good, produces a feeling of pleasure, he considers pleasure as a very powerful means of virtue.
Connected with Aristotle’s system of ethics was his system of politics, the former being only a part, as it were, of the latter; the former aiming at the happiness of individuals, the latter at that of communities; so that the latter is the perfection and completion of the former. For Aristotle looked upon man as a “political animal”—as a being, that is, created by nature for the state, and for living in the state; which, as a totality consisting of organically connected members, is by nature prior to the individual or the family. The state he looked upon as a whole consisting of mutually dependent and connected members, with reference as well to imaginary as to actually existing constitutions. The constitution is the arrangement of the powers in the state—the soul of the state, as it were,—according to which the sovereignty is determined. The laws are the determining principles, according to which the dominant body governs and restrains those who would, and punishes those who do, transgress them. He defines three kinds of constitutions, each of them having a corresponding perversion:—a republic, arising from the principle of equality; this at times degenerates into democracy; monarchy, and aristocracy, which arise from principles of inequality, founded on the preponderance of external or internal strength and wealth, and which are apt to degenerate into tyranny and oligarchy. The education of youth he considers as a principal concern of the state, in order that, all the individual citizens being trained to a virtuous life, virtue may become predominant in all the spheres of political life; and, accordingly, by means of politics the object is realized of which ethics are the groundwork, namely, human happiness, depending on a life in accordance with virtue.
_Heraclides_ Ponticus, as he is usually called, was, as his name denotes, a native of Pontus. He migrated to Athens, where he became a disciple of Plato, who, while absent in Sicily, entrusted him with the care of his school. _Speusippus_ was the nephew of Plato, and succeeded him as President of the Academy; but he continued so but a short time, and, within eight years of the death of Plato, he died at Athens, B.C. 339. He refused to recognise _the Good_ as the ultimate principle; but, going back to the older theologians, maintained that the origin of the universe was to be set down indeed as a cause of the Good and Perfect, but was not the Good and Perfect itself; for that was the result of generated existence or development, just as plants are of the seeds. When, with the Pythagoreans, he reckoned _the One_ in the series of good things, he probably thought of it only in opposition to _the Manifold_, and wished to point out that it is from _the One_ that _the Good_ is to be derived. He appears, however, (see De Nat. Deor. i. 13,) to have attributed vital activity to the primordial unity, as inseparably belonging to it. _Theophrastus_ was a native of Eresus, from whence he migrated to Athens, where he became a follower of Plato, and afterwards of Aristotle, by whom, when he quitted Athens for Chalcis, he was designated as his successor in the presidency of the Lyceum; while in this position, he is said to have had two thousand disciples, and among them the comic poet Menander. When, B.C. 305, the philosophers were banished from Athens, he also left the city, but returned the next year on the repeal of the law. He lived to a great age, though the date of his birth is not certainly known.
