Heraclitus's writings have exerted a wide influence on
Western philosophy, including the works of
Plato and
Aristotle, who interpreted him in terms of their own doctrines. His influence also extends into art, literature, and even medicine, as writings in the
Hippocratic corpus show signs of Heraclitean themes. Heraclitus is also considered a potential source for understanding the
Ancient Greek religion since the discovery of the
Derveni papyrus, an
Orphic poem which contains two fragments of Heraclitus.
Ancient It is unknown whether or not Heraclitus had any students in his lifetime. Diogenes Laertius states Heraclitus's book "won so great a fame that there arose followers of him called Heracliteans." Scholars took this to mean Heraclitus had no disciples and became renowned only after his death. According to one author, "The school of disciples founded by Heraclitus flourished for long after his death". According to another, "there were no doubt other Heracliteans whose names are now lost to us". In his dialogue
Cratylus, Plato presented
Cratylus as a Heraclitean and as a
linguistic naturalist who believed that names must apply naturally to their objects. According to Aristotle, Cratylus went a step beyond his master's doctrine and said that one cannot step into the same river once. He took the view that nothing can be said about the ever-changing world and "ended by thinking that one need not say anything, and only moved his finger". To explain both characterizations by Plato and Aristotle, Cratylus may have thought continuous change warrants skepticism because one cannot define a thing that does not have a permanent nature. Diogenes Laertius also lists an otherwise historically obscure Antisthenes who wrote a commentary on Heraclitus. The
Pythagorean and comic writer
Epicharmus of Kos has fragments which seem to reproduce the thought of Heraclitus, and wrote a play titled
Heraclitus.
Eleatics , a contemporary who espoused a doctrine of unchanging Being, has been contrasted with Heraclitus and his doctrine of constant change.
Parmenides of Elea, a philosopher and near-contemporary, proposed a doctrine of changelessness, in contrast to the doctrine of flux put forth by Heraclitus. He is generally agreed to either have influenced or been influenced by Heraclitus. Different philosophers have argued that either one of them may have substantially influenced each other, some taking Heraclitus to be responding to Parmenides, but more often Parmenides is seen as responding to Heraclitus. Some also argue that any direct chain of influence between the two is impossible to determine. Although Heraclitus refers to older figures such as Pythagoras, neither Parmenides or Heraclitus refer to each other by name in any surviving fragments, so any speculation on influence must be based on interpretation.
Pluralists and atomists The surviving fragments of several other pre-Socratic philosophers show Heraclitean themes.
Diogenes of Apollonia thought the action of one thing on another meant they were made of one substance. The
pluralists may have been influenced by Heraclitus. The philosopher
Anaxagoras refuses to separate the opposites in the "one cosmos".
Empedocles has forces (arguably the first since Heraclitus's tension) On one interpretation: "Essentially what the atomists did was try to find a middle-way between the contradictory philosophical schemes of Heraclitus and Parmenides."
Sophists The sophists, including
Protagoras of Abdera and
Gorgias of Leontini, may also have been influenced by Heraclitus. Sophists in general seemed to share Heraclitus's conception of the
logos. Heraclitus and others used "measure" to mean the balance and order of nature; hence Protagoras' famous statement "man is the measure of all things". In Plato's
dialogue Theaetetus, Socrates sees Protagoras's "man is the measure" doctrine and
Theaetetus' hypothesis that "knowledge is perception" as justified by Heraclitean flux. Gorgias seems to have been influenced by the
logos, when he argued in his work
On Non-Being, possibly parodying the Eleatics, that being cannot exist or be communicated. According to one author, Gorgias "in a sense ... completes Heraclitus."
Plato and Aristotle was a result of reconciling Heraclitus and Parmenides.|160px Plato knew of the teachings of Heraclitus through the Heraclitean philosopher Cratylus. Plato held that for Heraclitus knowledge is made impossible by the flux of sensible objects, and thus the need for the imperceptible
Forms as objects of knowledge.
Scythinus of Teos, a contemporary of Plato, wrote out Heraclitus's philosophy in verse. A four-volume work on Heraclitus was written by the academic
Heraclides Ponticus, but has not survived. Plutarch also wrote a lost treatise on Heraclitus. The Neoplatonists were influenced by Heraclitus on the topic of
the One; quoting
Plotinus "Heraclitus, with his sense of bodily forms as things of ceaseless process and passage, knows the One as eternal and intellectual." Aristotle accused Heraclitus of denying the law of noncontradiction, and charges that he thereby failed in his reasoning. However, Aristotle's material monist and world conflagration (
ekpyrosis) interpretation of Heraclitus influenced the Stoics. A four-volume work titled
Interpretation of Heraclitus was written by the Stoic philosopher Cleanthes, but has not survived. In surviving stoic writings, Heraclitean influence is most evident in the writings of
Marcus Aurelius. Marcus Aurelius understood the
Logos as "the account which governs everything". Heraclitus also states, "We should not act and speak like children of our parents", which Marcus Aurelius interpreted to mean one should not simply accept what others believe. Many of the later Stoics interpreted the
logos as the
arche, as a creative fire that ran through all things due to sunlight; According to one source, "the Cynic affinity with Heraclitus lies not so much in his philosophy as in his cultural criticism and (idealised) lifestyle." The Cynics attributed several of the later
Cynic epistles to his authorship. Heraclitus is sometimes even depicted as a cynic. Heraclitus' idea that most people live as if in a deep state of sleep resembles what the Cynics said about
typhos, a cloud of mist or fog shrouding all of existence. The Cynics took their name from their affinity for dogs and their lifestyle.
Pyrrhonists The skeptical philosophers known as
Pyrrhonists were also influenced by Heraclitus. He may be the predecessor to
Pyrrho's relativistic doctrine "No More This than That", that nothing is one way rather than another way. According to Pyrrhonist Sextus Empiricus,
Aenesidemus, one of the major ancient Pyrrhonist philosophers, claimed in a now-lost work that Pyrrhonism was a way to Heraclitean philosophy because Pyrrhonist practice helps one to see how opposites appear to be the case about the same thing, leading to the Heraclitean view that opposites actually are true about the same thing.
Early Christianity Hippolytus of Rome, one of the early
Church Fathers of the
Christian Church, identified Heraclitus along with the other pre-Socratics and
Academics as a source of
heresy, in Heraclitus's case namely the heresy of
Noetus. The Christian apologist
Justin Martyr took a more positive view of Heraclitus. In his
First Apology, he said both Socrates and Heraclitus were Christians before Christ: "those who lived reasonably are Christians, even though they have been thought atheists; as, among the Greeks, Socrates and Heraclitus, and men like them." He was among those who interpreted the
logos as meaning the Christian "Word of
God", such as in
John 1:1: "In the beginning was the Word (
logos) and the Word was God." The Christian Clement of Alexandria notes Heraclitus's similarity to the Christian prophets, and is cited as a source for more Heraclitus fragments than any other author.
Weeping philosopher Heraclitus's influence also extends outside of philosophy. A motif found in art and literature is Heraclitus as the "weeping philosopher" and Democritus as the "laughing philosopher", which references their reactions to the state of the world or the folly of mankind.The
Renaissance saw a revived interest in ancient philosophy and its depiction in art. A
fresco on the wall of the
Villa Medici at Careggi, near
Florence, which housed
Marsilio Ficino's
Platonic Academy, depicted Heraclitus and Democritus.
Donato Bramante painted Heraclitus and Democritus (1486) as the weeping and laughing philosopher, and may have depicted Heraclitus as
Leonardo da Vinci. Heraclitus appears in painter
Raphael's
School of Athens (1511), in which he is represented by
Michelangelo, since they shared a "sour temper and bitter scorn for all rivals". French humanist
Rabelais called Heraclitus a "blubbering whiner" in the fourth book (1552) of the
Gargantua and Pantagruel series.
Modern Modern interest in early Greek philosophy can be traced back to 1573, when French printer
Henri Estienne (also known as Henricus Stephanus) collected a number of pre-Socratic fragments, including some forty of those of Heraclitus, and published them in
Latin in
Poesis philosophica. Soon after,
Renaissance skeptic Michel de Montaigne's penned an
essay On Democritus and Heraclitus, in which he sided with the laughing philosopher over the weeping philosopher. (1628) English playwright
William Shakespeare may have known of Heraclitus through Montaigne.
The Merchant of Venice (1598) features the melancholic character of
Antonio, who some critics contend is modeled after Heraclitus. Additionally, in one scene of the play
Portia assesses her potential suitors, and says of one County Palatine: "I fear he will prove the weeping philosopher when he grows old". Several
baroque artists such as
Peter Paul Rubens,
Hendrik ter Brugghen, and
Johannes Moreelse painted Heraclitus and Democritus. Rubens'
Heraclitus and Democritus (1603) was painted for the
Duke of Lerma.
Rationalism Montaigne was a major influence on
rationalist philosopher
René Descartes, who wrote in
The Passions of the Soul that
indignation can be joined by
pity or
derision, "So the laughter of Democritus and the tears of Heraclitus could have come from the same cause". Kahn suggests Spinoza may have been influenced by Heraclitus via the Stoics. According to one author "What Heraclitus really meant by the common was...nothing different from what by
Spinoza was expressed by "
sub specie aeternitatis".
Gottfried Wilhelm Leibniz stated in
The Monadology "all bodies are in a state of perpetual flux like rivers."
British empiricism Bishop and
empiricist philosopher
George Berkeley claimed Sir
Isaac Newton's
alchemy was influenced by Heraclitus. Scottish skeptic
David Hume seems to recapitulate Heraclitus while discussing
personal identity: "Thus as the nature of a river consists in the motion and change of parts; tho' in less than four and twenty hours these be totally alter'd; this hinders not the river from continuing the same during several ages." While Heraclitus seems to criticize people in general, at other times he also seems to support
common sense. On
Scottish common sense philosopher
Thomas Reid's account, Heraclitus was one of the first to extol a common sense philosophy with such quotes as "And though reason is common, most people live as though they had an understanding peculiar to themselves;" and "understanding is common to all". As one author puts it, if Heraclitus did not like common sense, he certainly had a sense of the common.
Post-Kantianism Ever since German philosopher
Immanuel Kant, philosophers have sometimes been divided into rationalists and empiricists. Heraclitus has been considered each by different scholars. For rationalism, philosophers cite fragments like "Poor witnesses for men are the eyes and ears of those who have barbarian souls." For empiricism, they cite fragments like "The things that can be seen, heard, and learned are what I prize the most." The impression of Heraclitus on
German idealist G. W. F. Hegel was so profound that he remarked in his
Lectures on the History of Philosophy: "there is no proposition of Heraclitus which I have not adopted in my
Logic." Hegel interpreted Heraclitus as a dialetheist and as a process philosopher, seeing the flux or "becoming" in Heraclitus as a natural result of the
ontology of "being" and "non-being" in Parmenides. He also doubted the world conflagration (
ekpyrosis) interpretation, which had been popular since Aristotle. Gottlob Mayer has argued that the
philosophical pessimism of
Arthur Schopenhauer recapitulated the thought of Heraclitus.
Heraclitean studies The German theologian
Friedrich Schleiermacher was one of the first to collect the fragments of Heraclitus specifically and write them out in his native tongue, the "pioneer of Heraclitean studies". Schleiermacher was also one of the first to posit Persian influence upon Heraclitus, a question taken up by succeeding scholars
Friedrich Creuzer and August Gladisch. Lassalle also thought Persian theology influenced Heraclitus.
Hermann Diels wrote "Bywater's book has come to be accounted ... as the only reliable collection of the remains of that philosopher."
Continental The
continental existentialist and philologist
Friedrich Nietzsche preferred Heraclitus above all the other pre-Socratics. Nietzsche saw the philosophers before Plato as "pure
types" and Heraclitus as the proud, lonely truth-finder. The
nationalist philosopher of history Oswald Spengler wrote his (failed) dissertation on Heraclitus.
Phenomenologist Edmund Husserl wrote that
consciousness is "the realm of Heraclitean flux". Existentialist and phenomenologist
Martin Heidegger was also influenced by Heraclitus, as seen in his
Introduction to Metaphysics. Heidegger believed that the thinking of Heraclitus and Parmenides was the origin of philosophy and misunderstood by Plato and Aristotle, leading all of
Western philosophy astray. French philosophers
Jacques Derrida and
Gilles Deleuze's "differential ontology" is influenced by Heraclitus. According to Deleuze,
Michel Foucault was a Heraclitean. The idea that war produces order through strife is similar to Foucault's notion that
power is a force dispersed through social relations. In the 1950s, a term originating with Heraclitus, "
idios kosmos", meaning "private world" as distinguished from the "common world" () was adopted by phenomenological and
existential psychologists, such as
Ludwig Binswanger and
Rollo May, to refer to the experience of people with delusions. It was an important part of novelist
Philip K. Dick's views on
schizophrenia. Those thinkers have relied on Heraclitus's statement that "The waking have one common world, but the sleeping turn aside each into a world of his own." The Irish author and classicist
Oscar Wilde was influenced by art critic
Walter Pater, a friend of Bywater's whose "pre-Socratic hero" was Heraclitus.
Harold Bloom noted that "Pater praises Plato for Classic correctness, for a conservative
centripetal impulse, against his [Pater's] own Heraclitean
Romanticism."
Analytic The British
analytic and
process philosopher A. N. Whitehead has been identified as a representative of the tradition of Heraclitus. In
Bertrand Russell's essay
Mysticism and Logic, he contends Heraclitus proves himself a metaphysician by his blending of mystical and scientific impulses. Scholar Edward Hussey sees parallels between Heraclitus, the
logos, and the early
Ludwig Wittgenstein's linguistic philosophy in the
Tractatus (1922). Aristotle's arguments for the law of non-contradiction, which he saw as refuting the position started by Heraclitus, used to be considered authoritative, but have been in doubt ever since their criticism by Polish logician
Jan Łukasiewicz, and the invention of
many-valued and
paraconsistent logics. Some philosophers such as
Graham Priest and
Jc Beall follow Heraclitus in advocating true contradictions or dialetheism, seeing it as the most natural response to the
liar paradox. Jc Beall, together with
Greg Restall, is a pioneer of a widely discussed version of
logical pluralism. In contemporary
philosophy of religion, Beall argues for a contradictory account of
Jesus Christ as both man and divine. The Catholic philosopher
Peter Geach was inspired by Heraclitus's comments on the river to formulate his idea of
relative identity, which he used to defend the coherence of the
Trinity. The
British idealist John McTaggart is best known for his paper "
The Unreality of Time" (1908), in which he argues that time is unreal, inaugurating the field of contemporary
philosophy of time. What he calls the "
A theory", also known as "temporal becoming", and closely related to
presentism, which conceives of time as tensed (i.e., having the properties of being past, present, or future), is a view which has been seen as beginning with Heraclitus. By contrast, his "
B theory", under which time is tenseless (i.e., earlier than, simultaneous to, or later than), has similarly been seen as beginning with Parmenides. ==Notes==
