CHAPTER XVI

THE EPICUREANS

Epicurus was born at Samos in 342 B.C. He founded his school a year or

two before Zeno founded the Stoa, so that the two schools from the

first ran parallel in time. The school of Epicurus lasted over six

centuries. Epicurus early became acquainted with the atomism of

Democritus, but his learning in earlier systems of philosophy does not

appear to have been extensive. He was a man of estimable life and

character. He founded his school in 306 B.C. The Epicurean philosophy

was both founded and completed by him. No subsequent Epicurean to any

appreciable extent added to or altered the doctrines laid down by the

founder.

The Epicurean system is even more purely practical in tendency than

the Stoic. In spite of the fact that Stoicism subordinates logic and

physics to ethics, yet the diligence and care which the Stoics

bestowed upon such doctrines as those of the criterion of truth, the

nature of the world, the soul, and so on, afford evidence of a

genuine, if subordinate, interest in these subjects. Epicurus likewise

divided his system into logic (which he called canonic), physics, and

ethics, yet the two former branches of thought are pursued with an

obvious carelessness and absence of interest. It is evident that

learned {355} discussions bored Epicurus. His system is amiable and

shallow. Knowledge for its own sake is not desired. Mathematics, he

said, are useless, because they have no connexion with life. The

logic, or canonic, we may pass over completely, as possessing no

elements of interest, and come at once to the physics.

Physics.

Physics interests Epicurus only from one point of view--its power to

banish superstitious fear from the minds of men. All supernatural

religion, he thought, operates for the most part upon mankind by means

of fear. Men are afraid of the gods, afraid of retribution, afraid of

death because of the stories of what comes after death. This incessant

fear and anxiety is one of the chief causes of the unhappiness of men.

Destroy it, and we have at least got rid of the prime hindrance to

human happiness. We can only do this by means of a suitable doctrine

of physics. What is necessary is to be able to regard the world as a

piece of mechanism, governed solely by natural causes, without any

interference by supernatural beings, in which man is free to find his

happiness how and when he will, without being frightened by the bogeys

of popular religion. For though the world is ruled mechanically, man,

thought Epicurus in opposition to the Stoics, possesses free will, and

the problem of philosophy is to ascertain how he can best use this

gift in a world otherwise mechanically governed. What he required,

therefore, was a purely mechanical philosophy. To invent such a

philosophy for himself was a task not suited to his indolence, and for

which he could not pretend to possess the necessary {356}

qualifications. Therefore he searched the past, and soon found what he

wanted in the atomism of Democritus. This, as an entirely mechanical

philosophy, perfectly suited his ends, and the pragmatic spirit in

which he chose his beliefs, not on any abstract grounds of their

objective truth, but on the basis of his subjective needs and personal

wishes, will be noted. It is a sign of the times. When truth comes to

be regarded as something that men may construct in accordance with

their real or imagined needs, and not in accordance with any objective

standard, we are well advanced upon the downward path of decay.

Epicurus, therefore, adopted the atomism of Democritus _en bloc_, or

with trifling modifications. All things are composed of atoms and the

void. Atoms differ only in shape and weight, not in quality. They fall

eternally through the void. By virtue of free will, they deviate

infinitesimally from the perpendicular in their fall, and so clash

against one another. This, of course, is an invention of Epicurus, and

formed no part of the doctrine of Democritus. It might be expected of

Epicurus that his modifications would not be improvements. In the

present case, the attribution of free will to the atoms adversely

affects the logical consistency of the mechanical theory. From the

collision of atoms arises a whirling movement out of which the world

emerges. Not only the world, but all individual phenomena, are to be

explained mechanically. Teleology is rigorously excluded. In any

particular case, however, Epicurus is not interested to know what

particular causes determine a phenomenon. It is enough for him to be

sure that it is wholly determined by mechanical causes, and that

supernatural agencies are excluded.

{357}

The soul being composed of atoms which are scattered at death, a

future life is not to be thought of. But this is to be regarded as the

greatest blessing. It frees us from the fear of death, and the fear of

a hereafter. Death is not an evil. For if death is, we are not; if we

are, death is not. When death comes we shall not feel it, for is it

not the end of all feeling and consciousness? And there is no reason

to fear now what we know that we shall not feel when it comes.

Having thus disposed of the fear of retribution in a future life,

Epicurus proceeds to dispose of the fear of the interference of the

gods in this life. One might have expected that Epicurus would for

this purpose have embraced atheism. But he does not deny the existence

of the gods. On the contrary, he believed that there are innumerable

gods. They have the form of men, because that is the most beautiful of

all forms. They have distinctions in sex. They eat, drink, and talk

Greek. Their bodies are composed of a substance like light. But though

Epicurus allows them to exist, he is careful to disarm them, and to

rob them of their fears. They live in the interstellar spaces, an

immortal, calm, and blessed existence. They do not intervene in the

affairs of the world, because they are perfectly happy. Why should

they burden themselves with the control of that which nowise concerns

them? Theirs is the beatitude of a wholly untroubled joy.

"Immortal are they, clothed with powers,

Not to be comforted at all,

Lords over all the fruitless hours,

Too great to appease, too high to appal,

Too far to call." [Footnote 17]

[Footnote 17: A. C. Swinburne's _Felise_.]

{358}

Man, therefore, freed from the fear of death and the fear of the gods,

has no duty save to live as happily as he can during his brief space

upon earth. We can quit the realm of physics with a light heart, and

turn to what alone truly matters, ethics, the consideration of how man

ought to conduct his life.

Ethics.

If the Stoics were the intellectual successors of the Cynics, the

Epicureans bear the same relation to the Cyrenaics. Like Aristippus,

they founded morality upon pleasure, but they differ because they

developed a purer and nobler conception of pleasure than the Cyrenaics

had known. Pleasure alone is an end in itself. It is the only good.

Pain is the only evil. Morality, therefore, is an activity which

yields pleasure. Virtue has no value on its own account, but derives

its value from the pleasure which accompanies it.

This is the only foundation which Epicurus could find, or desired to

find, for moral activity. This is his only ethical principle. The rest

of the Epicurean ethics consists in the interpretation of the idea of

pleasure. And, firstly, by pleasure Epicurus did not mean, as the

Cyrenaics did, merely the pleasure of the moment, whether physical or

mental. He meant the pleasure that endures throughout a lifetime, a

happy life. Hence we are not to allow ourselves to be enslaved by any

particular pleasure or desire. We must master our appetites. We must

often forego a pleasure if it leads in the end to greater pain. We

must be ready to undergo pain for the sake of a greater pleasure to

come.

And it was just for this reason, secondly, that the {359} Epicureans

regarded spiritual and mental pleasures as far more important than

those of the body. For the body feels pleasure and pain only while

they last. The body has in itself neither memory nor fore-knowledge.

It is the mind which remembers and foresees. And by far the most

potent pleasures and pains are those of remembrance and anticipation.

A physical pleasure is a pleasure to the body only now. But the

anticipation of a future pain is mental anxiety, the remembrance of a

past joy is a present delight. Hence what is to be aimed at above all

is a calm untroubled mind, for the pleasures of the body are

ephemeral, those of the spirit enduring. The Epicureans, like the

Stoics, preached the necessity of superiority to bodily pains and

external circumstances. So a man must not depend for his happiness

upon externals; he must have his blessedness in his own self. The wise

man can be happy even in bodily torment, for in the inner tranquillity

of his soul he possesses a happiness which far outweighs any bodily

pain. Yet innocent pleasures of sense are neither forbidden, nor to be

despised. The wise man will enjoy whatever he can without harm. Of all

mental pleasures the Epicureans laid, perhaps, most stress upon

friendship. The school was not merely a collection of

fellow-philosophers, but above all a society of friends.

Thirdly, the Epicurean ideal of pleasure tended rather towards a

negative than a positive conception of it. It was not the state of

enjoyment that they aimed at, much less the excitement of the

feelings. Not the feverish pleasures of the world constituted their

ideal. They aimed rather at a negative absence of pain, at

tranquillity, quiet calm, repose of spirit, undisturbed by fears and

{360} anxieties. As so often with men whose ideal is pleasure, their

view of the world was tinged with a gentle and even luxurious

pessimism. Positive happiness is beyond the reach of mortals. All that

man can hope for is to avoid pain, and to live in quiet contentment.

Fourthly, pleasure does not consist in the multiplication of needs and

their subsequent satisfaction. The multiplication of wants only

renders it more difficult to satisfy them. It complicates life without

adding to happiness. We should have as few needs as possible. Epicurus

himself lived a simple life, and advised his followers to do the same.

The wise man, he said, living on bread and water, could vie with Zeus

himself in happiness. Simplicity, cheerfulness, moderation,

temperance, are the best means to happiness. The majority of human

wants, and the example of the thirst for fame is quoted, are entirely

unnecessary and useless.

Lastly, the Epicurean ideal, though containing no possibility of an

exalted nobility, was yet by no means entirely selfish. A kindly,

benevolent temper appeared in these men. It is pleasanter, they said,

to do a kindness than to receive one. There is little of the stern

stuff of heroes, but there is much that is gentle and lovable, in the

amiable moralizings of these butterfly-philosophers.
