Though Aristotle wrote in a methodical manner, his writings exhibit great parsimony of language. There is no fascination in his style. It is without ornament, and very condensed. His merit consisted in great logical precision and scrupulous exactness in the employment of terms.
Philosophy, as a great system of dialectics, as an analysis of the power and faculties of the mind, as a method to pursue inquiries, culminated in Aristotle. He completed the great fabric of which Thales laid the foundation. The subsequent schools of philosophy directed attention to ethical and practical questions, rather than to intellectual phenomena. The Sceptics, like Pyrrho, had only negative doctrines, and held in disdain those inquiries which sought to penetrate the mysteries of existence. They did not believe that absolute truth was attainable by man; and they attacked the prevailing systems with great plausibility. They pointed out the uncertainty of things, and the folly of striving to comprehend them.
The Epicureans despised the investigations of philosophy, since in their view these did not contribute to happiness. The subject of their inquiries was happiness, not truth. What will promote this? was the subject of their speculation. Epicurus, born 342 B.C., contended that pleasure was happiness; that pleasure should be sought not for its own sake, but with a view to the happiness of life obtained by it. He taught that happiness was inseparable from virtue, and that its enjoyments should be limited. He was averse to costly pleasures, and regarded contentedness with a little to be a great good. He placed wealth not in great possessions, but in few wants. He sought to widen the domain of pleasure and narrow that of pain, and regarded a passionless state of life as the highest. Nor did he dread death, which was deliverance from misery, as the Buddhists think. Epicurus has been much misunderstood, and his doctrines were subsequently perverted, especially when the arts of life were brought into the service of luxury, and a gross materialism was the great feature of society. Epicurus had much of the spirit of a practical philosopher, although very little of the earnest cravings of a religious man. He himself led a virtuous life, because he thought it was wiser and better and more productive of happiness to be virtuous, not because it was his duty. His writings were very voluminous, and in his tranquil garden he led a peaceful life of study and enjoyment. His followers, and they were numerous, were led into luxury and effeminacy,--as was to be expected from a sceptical and irreligious philosophy, the great principle of which was that whatever is pleasant should be the object of existence. Sir James Mackintosh says:--
"To Epicurus we owe the general concurrence of reflecting men in succeeding times in the important truth that men cannot be happy without a virtuous frame of mind and course of life,--a truth of inestimable value, not peculiar to the Epicureans, but placed by their exaggerations in a stronger light; a truth, it must be added, of less importance as a motive to right conduct than to the completeness of moral theory, which, however, it is very far from solely constituting. With that truth the Epicureans blended another position,--that because virtue promotes happiness, every act of virtue must be done in order to promote the happiness of the agent. Although, therefore, he has the merit of having more strongly inculcated the connection of virtue with happiness, yet his doctrine is justly charged with indisposing the mind to those exalted and generous sentiments without which no pure, elevated, bold, or tender virtues can exist."
The Stoics were a large and celebrated sect of philosophers; but they added nothing to the domain of thought,--they created no system, they invented no new method, they were led into no new psychological inquiries. Their inquiries were chiefly ethical; and since ethics are a great part of the system of Greek philosophy, the Stoics are well worthy of attention. Some of the greatest men of antiquity are numbered among them,--like Seneca, Epictetus, and Marcus Aurelius. The philosophy they taught was morality, and this was eminently practical and also elevated.
The founder of this sect, Zeno, was born, it is supposed, on the island of Cyprus, about the year 350 B.C. He was the son of wealthy parents, but was reduced to poverty by misfortune. He was so good a man, and so profoundly revered by the Athenians, that they intrusted to him the keys of their citadel. He lived in a degenerate age, when scepticism and sensuality were eating out the life and vigor of Grecian society, when Greek civilization was rapidly passing away, when ancient creeds had lost their majesty, and general levity and folly overspread the land. Deeply impressed with the prevailing laxity of morals and the absence of religion, he lifted up his voice more as a reformer than as an inquirer after truth, and taught for more than fifty years in a place called the Stoa, "the Porch," which had once been the resort of the poets. Hence the name of his school. He was chiefly absorbed with ethical questions, although he studied profoundly the systems of the old philosophers. "The Sceptics had attacked both perception and reason. They had shown that perception is after all based upon appearance, and appearance is not a certainty; and they showed that reason is unable to distinguish between appearance and certainty, since it had nothing but phenomena to build upon, and since there is no criterion to apply to reason itself." Then they proclaimed philosophy a failure, and without foundation. But Zeno, taking a stand on common-sense, fought for morality, as did Buddha before him, and long after him Reid and Beattie, when they combated the scepticism of Hume.
Philosophy, according to Zeno and other Stoics, was intimately connected with the duties of practical life. The contemplation, meditation, and thought recommended by Plato and Aristotle seemed only a covert recommendation of selfish enjoyment. The wisdom which it should be the aim of life to attain is virtue; and virtue is to live harmoniously with Nature. To live harmoniously with Nature is to exclude all personal ends; hence pleasure is to be disregarded, and pain is to be despised. And as all moral action must be in harmony with Nature the law of destiny is supreme, and all things move according to immutable fate. With the predominant tendency to the universal which characterized their system, the Stoics taught that the sage ought to regard himself as a citizen of the world rather than of any particular city or state. They made four things to be indispensable to virtue,--a knowledge of good and evil, which is the province of the reason; temperance, a knowledge of the due regulation of the sensual passions; fortitude, a conviction that it is good to suffer what is necessary; and justice, or acquaintance with what ought to be to every individual. They made perfection necessary to virtue; hence the severity of their system. The perfect sage, according to them, is raised above all influence of external events; he submits to the law of destiny; he is exempt from desire and fear, joy or sorrow; he is not governed even by what he is exposed to necessarily, like sorrow and pain; he is free from the restraints of passion; he is like a god in his mental placidity. Nor must the sage live only for himself, but for others also; he is a member of the whole body of mankind. He ought to marry, and to take part in public affairs; but he is to attack error and vice with uncompromising sternness, and will never weakly give way to compassion or forgiveness. Yet with this ideal the Stoics were forced to admit that virtue, like true knowledge, although theoretically attainable is practically beyond the reach of man. They were discontented with themselves and with all around them, and looked upon all institutions as corrupt. They had a profound contempt for their age, and for what modern society calls "success in life;" but it cannot be denied that they practised a lofty and stern virtue in their degenerate times. Their God was made subject to Fate; and he was a material god, synonymous with Nature. Thus their system was pantheistic. But they maintained the dignity of reason, and sought to attain to virtues which it is not in the power of man fully to reach.
Zeno lived to the extreme old age of ninety-eight, although his constitution was not strong. He retained his powers by great abstemiousness, living chiefly on figs, honey, and bread. He was a modest and retiring man, seldom mingling with a crowd, or admitting the society of more than two or three friends at a time. He was as plain in his dress as he was frugal in his habits,--a man of great decorum and propriety of manners, resembling noticeably in his life and doctrines the Chinese sage Confucius. And yet this good man, a pattern to the loftiest characters of his age, strangled himself. Suicide was not deemed a crime by his followers, among whom were some of the most faultless men of antiquity, especially among the Romans. The doctrines of Zeno were never popular, and were confined to a small though influential party.
With the Stoics ended among the Greeks all inquiry of a philosophical nature worthy of especial mention, until centuries later, when philosophy was revived in the Christian schools of Alexandria, where the Hebrew element of faith was united with the Greek ideal of reason. The struggles of so many great thinkers, from Thales to Aristotle, all ended in doubt and in despair. It was discovered that all of them were wrong, or rather partial; and their error was without a remedy, until "the fulness of time" should reveal more clearly the plan of the great temple of Truth, in which they were laying foundation stones.
The bright and glorious period of Greek philosophy was from Socrates to Aristotle. Philosophical inquiries began about the origin of things, and ended with an elaborate systematization of the forms of thought, which was the most magnificent triumph that the unaided intellect of man ever achieved. Socrates does not found a school, nor elaborate a system. He reveals most precious truths, and stimulates the youth who listen to his instructions by the doctrine that it is the duty of man to pursue a knowledge of himself, which is to be sought in that divine reason which dwells within him, and which also rules the world. He believes in science; he loves truth for its own sake; he loves virtue, which consists in the knowledge of the good.
