امپدوکلس در آکراگاس واقع در سیسیل متولد گردید. حدود سال ۴۵۰. ق. م به شهرت رسید. پس از فیثاغورس، بارزترین نمایندهٔ التقاطگران علم و عرفان است. راسل به شوخی فیثاغورس و امپدوکلس را ترکیبی از فیلسوف و پیامبر و دانشمند و شارلاتان میخواند. سیاستمداری دموکرات بود که داعیهٔ خدایی هم داشت.
نقل است زنی را که به مدت ۳۰ روز مرده میپنداشتهاند، زنده کردهاست. مشهورترین افسانهای که دربارهٔ امپدوکلس روایت کردهاند، این است که او در دهانهٔ آتشفشان اتنا پرید، به خیال آن که نمیمیرد و جاودان میماند. وی لنگه کفش خود را کنار دهانه جا گذاشت، و چون عادت داشت که کفشهای برنجین بپوشد، به آسانی شناخته شد البته دیوگنس لائرتیوس که این داستان را نقل میکند ما را آگاه میسازد که تیمائوس با همه این داستانها مخالف بود و صریحاً میگوید که وی به پلوپونز عزیمت کرد و هرگز برنگشت؛ بنابراین گزارش نحوه مرگ او مشکوک است و شاعر بزرگ آلمانی هولدرلین شعری دربارهٔ مرگ افسانه وار او نوشتهاست، که همچنان یک بازی ناتمام شعری است.
همچنین لااقل یک نمونه از نیرویی را که بعداً نیروی گریز از مرکز خوانده شد، کشف کرده بود. فهمیده بود که هرگاه یک فنجان آب را به ریسمانی ببندیم و مانند آتشگردان بگردانیم، آب از فنجان نمیریزد.
امپدوکلس عناصر اربعه را «سرچشمهٔ» زندگی مادّی میخواند. عناصر اربعه جاویدانند، ولی ممکن است به نسبتهای مختلفی با هم آمیخته شوند و مواد مرکبی را که ما در طبیعت میبینیم، به وجود آورند. تغییر، تجلّی درآمیختن و جداشدن مواد است. «مهر» یا «عشق» عنصرها را به درآمیختن با هم، و «نفرت» یا «کین» عنصرها را به گسستن دوباره از هم وامیدارد. مهر و کین نیز عنصرهایی مادیاند.
بر این اساس او هم ثبات و هم تغییر را در متافیزیکش گنجاندهاست. تغییر وجود دارد؛ اما عامل تغییر آنگونه که هراکلیتوس میگفت تنها ستیزه نیست؛ بلکه به نظر امپدوکلس «نفرت» یا «آفند» و «مهر» یا «عشق» با هم تغییر را پدیدمیآورند.«نفرت»، «عشق» و «عناصر اربعه» هم ارکان ثابت در متافیزیک او هستند، که تأثیر افکار پارمنیدس را نشان میدهند.
در کل امپدکلس کوشید تا عقیده پارمنیدس که به موجب آن وجود نه میتواند به وجود آید و نه از میان برود، و امر بدیهی و مشهود تغیر با وضع این اصل سازش برقرار کند که اختلاط اجزا نهایی چهار عنصر اشیا انضمامی، این عالم را میسازد؛ و جدایی آنها از میان رفتن این اشیا را موجب میشود. اما وی موفق به تبیین فرایند دایره وار مادی طبیعت نشد و به نیروهای اساطیری عشق و نفرت روی آورد.
در اندیشه امپدوکلس جریان هستی و فعالیت دو نیروی مهر و آفند در چهار مرحله گنجانده شدهاست که به صورت دایره ای انجام میگیرد. مرحله نخست یگانگی یا وحدت کامل عنصر هاست که در آن کثرت وجود نداشت و همه عناصر در زیر فرمان مهر در کره هستی بهم پیوسته، و بدینسان یکی بودند. مرحله دوم آغاز انتقال عنصرها از یگانگی به جدایی و پراکندگی است، که در اثر نفوذ نیروی آفند در کره هستی روی میدهد که تاکنون در بیرون آن و در پیرامون کره جای داشت. در مرحله سوم پراکندگی و از هم جداشدگی کامل عناصر روی میدهد که نشانه تسلط و فرمانروایی کامل نیروی ستیزه یا آفند است. در مرحله چهارم، بار دیگر بازگشت به حالت یگانگی یا وحدت عناصر روی میدهد. از این چهار مرحله، پیدایش هستندههای مشخص، تنها در دو مرحله دوم و چهارم امکانپذیر است؛ بنابراین هستی جریان یک کشاکش پیوسته و جاوید است میان دو نیروی مهر و آفند که میتوان از آن به کشاکش اضداد تعبیر کرد، و یگانگی هستی را در عین بسیاری و کثرت آن را در عین وحدت، یا بسیاری آن را در عین یگانگی نشان میدهد. از این لحاظ میتوان او را متأثر از اندیشههای هراکلیتوس شمرد.

Empedocles (//; Greek: Ἐμπεδοκλῆς [empedoklɛ̂ːs], Empedoklēs; c. 494 – c. 434 BC) was a Greek pre-Socratic philosopher and a citizen of Akragas, a Greek city in Sicily. Empedocles' philosophy is best known for originating the cosmogonic theory of the four classical elements. He also proposed forces he called Love and Strife which would mix and separate the elements, respectively. These physical speculations were part of a history of the universe which also dealt with the origin and development of life.
Influenced by Pythagoras (died c. 495 BC) and the Pythagoreans, Empedocles challenged the practice of animal sacrifice and killing animals for food. He developed a distinctive doctrine of reincarnation. He is generally considered the last Greek philosopher to have recorded his ideas in verse. Some of his work survives, more than is the case for any other pre-Socratic philosopher. Empedocles' death was mythologized by ancient writers, and has been the subject of a number of literary treatments.
Empedocles was born, c. 490 BC, at Akragas in Sicily to a distinguished family. Very little is known about his life. His father Meton seems to have been instrumental in overthrowing the tyrant of Akragas, presumably Thrasydaeus in 470 BC. Empedocles continued this tradition by helping to overthrow the succeeding oligarchic government. He is said to have been magnanimous in his support of the poor; severe in persecuting the overbearing conduct of the oligarchs; and he even declined the sovereignty of the city when it was offered to him.
His brilliant oratory, his penetrating knowledge of nature, and the reputation of his marvellous powers, including the curing of diseases, and averting epidemics, produced many myths and stories surrounding his name. In his poem Purifications he claimed miraculous powers, including the destruction of evil, the curing of old age, and the controlling of wind and rain.
Empedocles was acquainted or connected by friendship with the physicians Pausanias (his eromenos) and Acron; with various Pythagoreans; and even, it is said, with Parmenides and Anaxagoras. The only pupil of Empedocles who is mentioned is the sophist and rhetorician Gorgias.
Timaeus and Dicaearchus spoke of the journey of Empedocles to the Peloponnese, and of the admiration, which was paid to him there; others mentioned his stay at Athens, and in the newly founded colony of Thurii, 446 BC; there are also fanciful reports of him travelling far to the east to the lands of the Magi.
According to Aristotle, he died at the age of sixty (c. 430 BC), even though other writers have him living up to the age of one hundred and nine. Likewise, there are myths concerning his death: a tradition, which is traced to Heraclides Ponticus, represented him as having been removed from the Earth; whereas others had him perishing in the flames of Mount Etna. 
The contemporary Life of Empedocles by Xanthus has been lost.
Empedocles is considered the last Greek philosopher to write in verse. There is a debate about whether the surviving fragments of his teaching should be attributed to two separate poems, Purifications and On Nature, with different subject matter, or whether they may all derive from one poem with two titles, or whether one title refers to part of the whole poem. Some scholars argue that the title Purifications refers to the first part of a larger work called (as a whole) On Nature. There is also a debate about which fragments should be attributed to each of the poems, if there are two poems, or if part of it is called "Purifications"; because ancient writers rarely mentioned which poem they were quoting. Empedocles was undoubtedly acquainted with the didactic poems of Xenophanes and Parmenides—allusions to the latter can be found in the fragments—but he seems to have surpassed them in the animation and richness of his style, and in the clearness of his descriptions and diction. Aristotle called him the father of rhetoric, and, although he acknowledged only the meter as a point of comparison between the poems of Empedocles and the epics of Homer, he described Empedocles as Homeric and powerful in his diction. Lucretius speaks of him with enthusiasm, and evidently viewed him as his model. The two poems together comprised 5000 lines. About 550 lines of his poetry survive.
In the old editions of Empedocles, only about 100 lines were typically ascribed to his Purifications, which was taken to be a poem about ritual purification, or the poem that contained all his religious and ethical thought. Early editors supposed that it was a poem that offered a mythical account of the world which may, nevertheless, have been part of Empedocles' philosophical system. According to Diogenes Laërtius it began with the following verses:
Friends who inhabit the mighty town by tawny Acragas
In the older editions, it is to this work that editors attributed the story about souls, where we are told that there were once spirits who lived in a state of bliss, but having committed a crime (the nature of which is unknown) they were punished by being forced to become mortal beings, reincarnated from body to body. Humans, animals, and even plants are such spirits. The moral conduct recommended in the poem may allow us to become like gods again. If, as is now widely held, this title "Purifications" refers to the poem On Nature, or to a part of that poem, this story will have been at the beginning of the main work on nature and the cosmic cycle. The relevant verses are also sometimes attributed to the proem of On Nature, even by those who think that there was a separate poem called "Purifications".
There are about 450 lines of his poem On Nature extant, including 70 lines which have been reconstructed from some papyrus scraps known as the Strasbourg Papyrus. The poem originally consisted of 2000 lines of hexameter verse, and was addressed to Pausanias. It was this poem which outlined his philosophical system. In it, Empedocles explains not only the nature and history of the universe, including his theory of the four classical elements, but he describes theories on causation, perception, and thought, as well as explanations of terrestrial phenomena and biological processes.
Although acquainted with the theories of the Eleatics and the Pythagoreans, Empedocles did not belong to any one definite school. An eclectic in his thinking, he combined much that had been suggested by Parmenides, Pythagoras and the Ionian schools. He was a firm believer in Orphic mysteries, as well as a scientific thinker and a precursor of physics. Aristotle mentions Empedocles among the Ionic philosophers, and he places him in very close relation to the atomist philosophers and to Anaxagoras.
According to House (1956)
Empedocles, like the Ionian philosophers and the atomists, continued the tradition of tragic thought which tried to find the basis of the relationship of the one and many. Each of the various philosophers, following Parmenides, derived from the Eleatics, the conviction that an existence could not pass into non-existence, and vice versa. Yet, each one had his peculiar way of describing this relation of Divine and mortal thought and thus of the relation of the One and the Many. In order to account for change in the world, in accordance with the ontological requirements of the Eleatics, they viewed changes as the result of mixture and separation of unalterable fundamental realities. Empedocles held that the four elements (Water, Air, Earth, and Fire) were those unchangeable fundamental realities, which were themselves transfigured into successive worlds by the powers of Love and Strife (Heraclitus had explicated the Logos or the "unity of opposites").
The four elements
Empedocles established four ultimate elements which make all the structures in the world—fire, air, water, earth. Empedocles called these four elements "roots", which he also identified with the mythical names of Zeus, Hera, Nestis, and Aidoneus (e.g., "Now hear the fourfold roots of everything: enlivening Hera, Hades, shining Zeus. And Nestis, moistening mortal springs with tears.") Empedocles never used the term "element" (στοιχεῖον, stoicheion), which seems to have been first used by Plato. According to the different proportions in which these four indestructible and unchangeable elements are combined with each other the difference of the structure is produced. It is in the aggregation and segregation of elements thus arising, that Empedocles, like the atomists, found the real process which corresponds to what is popularly termed growth, increase or decrease. Nothing new comes or can come into being; the only change that can occur is a change in the juxtaposition of element with element. This theory of the four elements became the standard dogma for the next two thousand years.
Love and Strife
The four elements, however, are simple, eternal, and unalterable, and as change is the consequence of their mixture and separation, it was also necessary to suppose the existence of moving powers that bring about mixture and separation. The four elements are both eternally brought into union and parted from one another by two divine powers, Love and Strife or Hatred. Love (φιλότης) is responsible for the attraction of different forms of matter, and Strife (νεῖκος) is the cause of their separation. If the four elements make up the universe, then Love and Strife explain their variation and harmony. Love and Strife are attractive and repulsive forces, respectively, which are plainly observable in human behavior, but also pervade the universe. The two forces wax and wane in their dominance, but neither force ever wholly escapes the imposition of the other.
The sphere of Empedocles
As the best and original state, there was a time when the pure elements and the two powers co-existed in a condition of rest and inertness in the form of a sphere. The elements existed together in their purity, without mixture and separation, and the uniting power of Love predominated in the sphere: the separating power of Strife guarded the extreme edges of the sphere. Since that time, strife gained more sway and the bond which kept the pure elementary substances together in the sphere was dissolved. The elements became the world of phenomena we see today, full of contrasts and oppositions, operated on by both Love and Strife. The sphere being the embodiment of pure existence is the embodiment or representative of God. Empedocles assumed a cyclical universe whereby the elements return and prepare the formation of the sphere for the next period of the universe.
Empedocles attempted to explain the separation of elements, the formation of earth and sea, of Sun and Moon, of atmosphere. He also dealt with the first origin of plants and animals, and with the physiology of humans. As the elements entered into combinations, there appeared strange results—heads without necks, arms without shoulders. Then as these fragmentary structures met, there were seen horned heads on human bodies, bodies of oxen with human heads, and figures of double sex. But most of these products of natural forces disappeared as suddenly as they arose; only in those rare cases where the parts were found to be adapted to each other did the complex structures last. Thus the organic universe sprang from spontaneous aggregations that suited each other as if this had been intended. Soon various influences reduced creatures of double sex to a male and a female, and the world was replenished with organic life. It is possible to see this theory as an anticipation of Charles Darwin's theory of natural selection, although Empedocles was not trying to explain evolution.
Perception and knowledge
Empedocles is credited with the first comprehensive theory of light and vision. He put forward the idea that we see objects because light streams out of our eyes and touches them. While flawed, this became the fundamental basis on which later Greek philosophers and mathematicians like Euclid would construct some of the most important theories of light, vision, and optics.
Knowledge is explained by the principle that elements in the things outside us are perceived by the corresponding elements in ourselves. Like is known by like. The whole body is full of pores and hence respiration takes place over the whole frame. In the organs of sense these pores are specially adapted to receive the effluences which are continually rising from bodies around us; thus perception occurs. In vision, certain particles go forth from the eye to meet similar particles given forth from the object, and the resultant contact constitutes vision. Perception is not merely a passive reflection of external objects.
Empedocles noted the limitation and narrowness of human perceptions. We see only a part but fancy that we have grasped the whole. But the senses cannot lead to truth; thought and reflection must look at the thing from every side. It is the business of a philosopher, while laying bare the fundamental difference of elements, to show the identity that exists between what seem unconnected parts of the universe.
In a famous fragment, Empedocles attempted to explain the phenomena of respiration by means of an elaborate analogy with the clepsydra, an ancient device for conveying liquids from one vessel to another. This fragment has sometimes been connected to a passage in Aristotle's Physics where Aristotle refers to people who twisted wineskins and captured air in clepsydras to demonstrate that void does not exist. There is however, no evidence that Empedocles performed any experiment with clepsydras. The fragment certainly implies that Empedocles knew about the corporeality of air, but he says nothing whatever about the void. The clepsydra was a common utensil and everyone who used it must have known, in some sense, that the invisible air could resist liquid.
Like Pythagoras, Empedocles believed in the transmigration of the soul/metempsychosis, that souls can be reincarnated between humans, animals and even plants. For Empedocles, all living things were on the same spiritual plane; plants and animals are links in a chain where humans are a link too. Empedocles was a vegetarian and advocated vegetarianism, since the bodies of animals are the dwelling places of punished souls. Wise people, who have learned the secret of life, are next to the divine, and their souls, free from the cycle of reincarnations, are able to rest in happiness for eternity.
Death and literary treatments
Diogenes Laërtius records the legend that Empedocles died by throwing himself into Mount Etna in Sicily, so that the people would believe his body had vanished and he had turned into an immortal god; the volcano, however, threw back one of his bronze sandals, revealing the deceit. Another legend maintains that he threw himself into the volcano to prove to his disciples that he was immortal; he believed he would come back as a god after being consumed by the fire. Horace also refers to the death of Empedocles in his work Ars Poetica and admits poets the right to destroy themselves.
In Icaro-Menippus, a comedic dialogue written by the second century satirist Lucian of Samosata, Empedocles’ final fate is re-evaluated. Rather than being incinerated in the fires of Mount Etna, he was carried up into the heavens by a volcanic eruption. Although a bit singed by the ordeal, Empedocles survives and continues his life on the Moon, surviving by feeding on dew.
Empedocles' death has inspired two major modern literary treatments. Empedocles' death is the subject of Friedrich Hölderlin's play Tod des Empedokles (The Death of Empedocles), two versions of which were written between the years 1798 and 1800. A third version was made public in 1826. In Matthew Arnold's poem Empedocles on Etna, a narrative of the philosopher's last hours before he jumps to his death in the crater first published in 1852, Empedocles predicts:
To the elements it came from
