These different cultures and even individual philosophers had widely varying explanations concerning their attributes and how they related to observable phenomena as well as [[Astronomy:Cosmology|cosmology]]. Sometimes these theories overlapped with mythology and were personified in deities. Some of these interpretations included [[Philosophy:Atomism|atomism]] (the idea of very small, indivisible portions of matter), but other interpretations considered the elements to be divisible into infinitely small pieces without changing their nature.

While the classification of the material world in ancient [[Philosophy:Mahābhūta|India]], Hellenistic Egypt, and ancient Greece into air, earth, fire, and water was more philosophical, during the [[History:Middle Ages|Middle Ages]] medieval [[Scientist|scientist]]s used practical, experimental observation to classify materials.<ref name="Jim">{{Cite AV media |title=Science and Islam |last=Al-Khalili |first=Jim |publisher=BBC |year=2009 |title-link=Science and Islam (TV series)}}</ref> In [[Earth:Europe|Europe]], the ancient Greek concept, devised by [[Biography:Empedocles|Empedocles]], evolved into the systematic classifications of [[Biography:Aristotle|Aristotle]] and [[Biography:Hippocrates|Hippocrates]]. This evolved slightly into the medieval system, and eventually became the object of experimental verification in the 1600s, at the start of the Scientific Revolution.<ref>{{Cite journal |date=1937-12-01 |title=Chemistry in the Ancient World |journal=Nature |language=en |volume=140 |issue=3554 |pages=1006 |doi=10.1038/1401006a0 |bibcode=1937Natur.140Q1006. |s2cid=44886438 |issn=1476-4687|doi-access=free }}</ref>

[[History:History of science#Modern science|Modern science]] does not support the classical elements to classify types of substances. [[Physics:Atomic theory|Atomic theory]] classifies atoms into more than a hundred [[Chemistry:Chemical element|chemical element]]s such as [[Chemistry:Oxygen|oxygen]], [[Chemistry:Iron|iron]], and [[Chemistry:Mercury (element)|mercury]], which may form [[Chemistry:Chemical compound|chemical compound]]s and mixtures. The modern categories roughly corresponding to the classical elements are the [[Physics:States of matter|states of matter]] produced under different temperatures and pressures. [[Physics:Solid|Solid]], [[Physics:Liquid|liquid]], [[Physics:Gas|gas]], and [[Physics:Plasma|plasma]] share many attributes with the corresponding classical elements of earth, water, air, and fire, but these states describe the similar behavior of different types of atoms at similar energy levels, not the characteristic behavior of certain atoms or substances.

The [[History:History of science in classical antiquity#Pre-Socratic philosophers|ancient Greek]] concept of four basic elements, these being earth ({{lang|grc|γῆ}}  {{transliteration|grc|gê}}), water ({{lang|grc|ὕδωρ}} {{transliteration|grc|hýdōr}}), air ({{lang|grc|ἀήρ}} {{transliteration|grc|aḗr}}), and fire ({{lang|grc|πῦρ}} {{transliteration|grc|pŷr}}), dates from pre-Socratic times and persisted throughout the [[History:Middle Ages|Middle Ages]] and into the [[History:Early modern period|Early modern period]], deeply influencing [[Earth:Europe|Europe]]an thought and culture.{{sfnp|Curd|2020}}

=== Pre-Socratic elements ===

==== Fire, earth, air, and water ====
The [[Place:Magna Graecia|Sicilian Greek]] philosopher [[Biography:Empedocles|Empedocles]] ({{circa|450 BC}}) was the first to propose the four classical elements as a set: fire, earth, air, and water.{{sfnp|Russell|1991|pp=62, 75}} He called them the four "roots" ({{lang|grc|ῥιζώματα}}, {{transliteration|grc|rhizōmata}}). Empedocles also proved (at least to his own satisfaction) that air was a separate substance by observing that a bucket inverted in water did not become filled with water, a pocket of air remaining trapped inside.{{sfnp|Russell|1991|p=72}}

Fire, earth, air, and water have become the most popular set of classical elements in modern interpretations. One such version was provided by [[Biography:Robert Boyle|Robert Boyle]] in ''[[Chemistry:The Sceptical Chymist|The Sceptical Chymist]]'', which was published in 1661 in the form of a dialogue between five characters. ''Themistius,'' the [[Philosophy:Aristotelianism|Aristotelian]] of the party, says:<ref>{{Cite book |last=Boyle |first=Robert |url=https://www.gutenberg.org/files/22914/22914-h/22914-h.htm |title=The Sceptical Chymist: or Chymico-Physical Doubts & Paradoxes, Touching the Spagyrist's Principles Commonly call'd Hypostatical; As they are wont to be Propos'd and Defended by the Generality of Alchymists.

The water ... boyling and hissing at the ends of the burning Wood betrayes it self ... and the ashes by their weight, their firiness, and their dryness, put it past doubt that they belong to the Element of Earth.}}

=== Humorism (Hippocrates) ===
According to [[Biography:Galen|Galen]], these elements were used by [[Biography:Hippocrates|Hippocrates]] (c. 460 – c. 370 BC) in describing the [[Medicine:Human body|human body]] with an association with the four humours: yellow [[Biology:Bile|bile]] (fire), [[Philosophy:Melancholia|black bile]] (earth), [[Biology:Blood|blood]] (air), and [[Biology:Phlegm|phlegm]] (water). Medical care was primarily about helping the patient stay in or return to their own personal natural balanced state.<ref>{{Cite book |last=Lindemann |first=Mary |title=Medicine and Society in early Modern Europe |publisher=Cambridge University Press |year=2010 |isbn=978-0-521-73256-7 |page=19}}</ref>

=== Plato ===
[[Biography:Plato|Plato]] (428/423 – 348/347 BC) seems to have been the first to use the term "element ({{lang|grc|στοιχεῖον}}, {{transliteration|grc|stoicheîon}})" in reference to air, fire, earth, and water.<ref>{{Citation |last=Plato |title=Timaeus |url=https://www.perseus.tufts.edu/cgi-bin/ptext?lookup=Plat.+Tim.+48b |at=48b}}</ref>  The ancient Greek word for element, {{transliteration|grc|stoicheion}} (from {{transliteration|grc|stoicheo}}, "to line up") meant "smallest division (of a sun-dial), a syllable", as the composing unit of an alphabet it could denote a letter and the smallest unit from which a word is formed.

=== Aristotle ===
In ''[[Astronomy:On the Heavens|On the Heavens]]'' (350 BC), Aristotle defines "element" in general:<ref>{{Citation |last1=Weisberg |first1=M. |title=Philosophy of Chemistry |date=2019 |url=https://plato.stanford.edu/archives/spr2019/entries/chemistry/ |encyclopedia=The Stanford Encyclopedia of Philosophy |editor-last=Zalta |editor-first=E.

L. |orig-date=350 BCE}}</ref>
{{Blockquote|An element, we take it, is a body into which other bodies may be analysed, present in them potentially or in actuality (which of these, is still disputable), and not itself divisible into bodies different in form. That, or something like it, is what all men in every case mean by element.<ref>{{Citation |author=Aristotle |title=[[Astronomy:On the Heavens|On the Heavens]] |at=III.3.302a17–19 |translator-last=Stocks |translator-first=J.L.}}</ref>|author=Aristotle|title=On the Heavens|source=Book III, Chapter III}}

In his ''On Generation and Corruption'',<ref>{{cite wikisource |author=Aristotle |wslink=Περί Γενέσεως και Φθοράς/2 |anchor=Κεφάλαιο 3 |wslanguage=el |quote={{lang|grc|τὸ μὲν γὰρ πῦρ θερμὸν καὶ ξηρόν, ὁ δ' ἀὴρ θερμὸν καὶ ὑγρόν (οἷον ἀτμὶς γὰρ ὁ ἀήρ), τὸ δ' ὕδωρ ψυχρὸν καὶ ὑγρόν, ἡ δὲ γῆ ψυχρὸν καὶ ξηρόν}}}}</ref>{{sfnp|Lloyd|1968|pp=166–169}} Aristotle related each of the four elements to two of the four sensible qualities:
* [[Unsolved:Fire (classical element)|'''Fire''']] is both hot and dry.
* [[Physics:Air (classical element)|'''Air''']] is both hot and wet (for air is like vapor, {{lang|grc|ἀτμὶς}}).
* [[Chemistry:Water (classical element)|'''Water''']] is both cold and wet.
* [[Unsolved:Earth (classical element)|'''Earth''']] is both cold and dry.

A classic diagram has one square inscribed in the other, with the corners of one being the classical elements, and the corners of the other being the properties. The opposite corner is the opposite of these properties, "hot – cold" and "dry – wet".

==== Aether ====
[[Biography:Aristotle|Aristotle]] added a fifth element, [[Philosophy:Aether (classical element)#Fifth element|aether]] ({{lang|grc|αἰθήρ}} {{transliteration|grc|aither}}), as the quintessence, reasoning that whereas fire, earth, air, and water were earthly and corruptible, since no changes had been perceived in the heavenly regions, the [[Astronomy:Star|star]]s cannot be made out of any of the four elements but must be made of a different, unchangeable, heavenly substance.{{sfnp|Lloyd|1968|pp=[https://archive.org/details/aristotlegrowths0000lloy/page/133 133–139]}} It had previously been believed by pre-Socratics such as Empedocles and [[Biography:Anaxagoras|Anaxagoras]] that aether, the name applied to the material of heavenly bodies, was a form of fire. Aristotle himself did not use the term ''aether'' for the fifth element, and strongly criticised the pre-Socratics for associating the term with fire. He preferred a number of other terms indicating eternal movement, thus emphasising the evidence for his discovery of a new element.<ref>{{Cite encyclopedia |year=1971 |chapter=Aristotle's analysis of change and Plato's theory of Transcendent Ideas |publisher=SUNY Press |last=Chung-Hwan |first=Chen |editor-last=Anton |editor-first=John P. |volume=2 |pages=406–407 |isbn=0873956230 |editor2-first=Anthony |editor2-last=Preus |title=Ancient Greek Philosophy}}.</ref> These five elements have been associated since Plato's [[Astronomy:Timaeus (dialogue)|''Timaeus'']] with the five [[Platonic solid|platonic solid]]s.

=== Neo-Platonism ===
The Neoplatonic philosopher [[Biography:Proclus|Proclus]] rejected Aristotle's theory relating the elements to the sensible qualities hot, cold, wet, and dry. He maintained that each of the elements has three properties. Fire is sharp, subtle, and mobile while its opposite, earth, is blunt, dense, and immobile; they are joined by the intermediate elements, air and water, in the following fashion:<ref>{{Citation |author=Proclus |title=Commentary on Plato's ''Timaeus'' |at=3.38.1–3.39.28}}</ref>

=== Hermeticism ===
{{anchor|Classical elements in Egypt}}
A text written in Egypt in [[History:Ptolemaic Kingdom|Hellenistic]] or Roman times called the ''Kore Kosmou'' ("Virgin of the World") ascribed to Hermes Trismegistus (associated with the Egyptian god [[Religion:Thoth|Thoth]]), names the four elements fire, water, air, and earth. As described in this book:

{{blockquote|And Isis answer made: Of living things, my son, some are made friends with ''fire'', and some with ''water'', some with ''air'', and some with ''earth'', and some with two or three of these, and some with all. And, on the contrary, again some are made enemies of fire, and some of water, some of earth, and some of air, and some of two of them, and some of three, and some of all. For instance, son, the locust and all flies flee fire; the eagle and the hawk and all high-flying birds flee water; fish, air and earth; the snake avoids the open air. Whereas snakes and all creeping things love earth; all swimming things love water; winged things, air, of which they are the citizens; while those that fly still higher love the fire and have the habitat near it. Not that some of the animals as well do not love fire; for instance salamanders, for they even have their homes in it. It is because one or another of the elements doth form their bodies’ outer envelope. Each [[Philosophy:Soul|soul]], accordingly, while it is in its body is weighted and constricted by these four.<ref>{{cite book |last=Mead |first=G. R.

They further suggest that all of creation, including the human body, is made of these five essential elements and that upon death, the human body dissolves into these five elements of nature, thereby balancing the cycle of nature.<ref>{{Cite book |last=Jagannathan |first=Maithily |title=South Indian Hindu Festivals and Traditions |publisher=Abhinav Publications |pages=60–62}}</ref>

The five elements are associated with the five senses, and act as the gross medium for the experience of sensations. The basest element, earth, created using all the other elements, can be perceived by all five senses — (i) hearing, (ii) touch, (iii) sight, (iv) taste, and (v) smell. The next higher element, water, has no odor but can be heard, felt, seen and tasted. Next comes fire, which can be heard, felt and seen. Air can be heard and felt. "Akasha" (aether) is beyond the senses of smell, taste, sight, and touch; it being accessible to the sense of hearing alone.<ref>{{Cite book |last=Meyer-Dinkgräfe |first=Daniel |url=https://books.google.com/books?id=zGy0UglRz6IC |title=Theatre and Consciousness: Explanatory Scope and Future Potential |publisher=Intellect Books |year=2005 |isbn=9781841501307}}</ref><ref>{{Cite book |last=Nath |first=Samir |url=https://books.google.com/books?id=cojAfyr04UAC |title=Encyclopaedic Dictionary of Buddhism |publisher=Sarup & Sons |year=1998 |isbn=9788176250191 |page=653}}</ref><ref>{{Cite book |last=Tirupati Raju |first=Poola |title=Structural Depths of Indian Thought: Toward a Constructive Postmodern Ethics |publisher=SUNY Press |page=81}}</ref>

===Buddhism===
{{anchor|Buddhist elements}}
{{Main|Philosophy:Mahābhūta}}

Buddhism has had a variety of thought about the five elements and their existence and relevance, some of which continue to this day.

In the Pali literature, the ''mahabhuta'' ("great elements") or ''catudhatu'' ("four elements") are earth, water, fire and air. In early Buddhism, the four elements are a basis for understanding suffering and for liberating oneself from suffering. The earliest [[Religion:Buddhist texts|Buddhist texts]] explain that the four primary material elements are solidity, fluidity, temperature, and mobility, characterized as earth, water, fire, and air, respectively.<ref>{{Cite book |title=The Middle Length Discourses of the Buddha: a New Translation of the Majjhima Nikaya |publisher=Wisdom Publications in association with the Barre Center for Buddhist Studies |year=1995 |isbn=0-86171-072-X |editor-last=Bodhi |location=Boston |chapter=28, Mahāhatthipadopamasutta |oclc=31331607}}</ref>

The [[Biography:Gautama Buddha|Buddha]]'s teaching regarding the four elements is to be understood as the base of all observation of real sensations rather than as a philosophy. The four properties are cohesion (water), solidity or inertia (earth), expansion or vibration (air) and heat or energy content (fire). He promulgated a categorization of mind and matter as composed of eight types of "kalapas" of which the four elements are primary and a secondary group of four are colour, smell, taste, and nutriment which are derivative from the four primaries.<ref>{{Cite book |last=Thera |first=Narada |title=A Manual of Abhidhamma |publisher=Buddhist Missionary Society |year=1956 |pages=318–320}}</ref>{{efn|{{harvp|Thera|1956|pages=318–320}}: "the atomic theory prevailed in India in the time of the Buddha. Paramàõu was the ancient term for the modern atom. According to the ancient belief one rathareõu consists of 16 tajjàris, one tajjàri, 16 aõus; one aõu, 16 paramàõus. The minute particles of dust seen dancing in the sunbeam are called rathareõus. One para-màõu is, therefore, 4096th part of a rathareõu. This para-màõu was considered indivisible. With His supernormal knowledge the Buddha analysed this so-called paramàõu and declared that it consists of paramatthas—ultimate entities which cannot further be subdivided." "ñhavi in earth, àpo in water, tejo in fire, and vàyo in air. They are also called Mahàbhåtas or Great Essentials because they are invariably found in all material substances ranging from the infinitesimally small cell to the most massive object. Dependent on them are the four subsidiary material qualities of colour (vaõõa)., smell (gandha), taste (rasa), and nutritive essence (ojà). These eight coexisting forces and qualities constitute one material group called 'Suddhaññhaka Rupa kalàpa—pure-octad material group'."}}<ref>{{Cite book |last=Anuruddha |title=A Comprehensive Manual of Abhidhamma: the Abhidhammattha Sangaha of Ācariya Anuruddha |publisher=Buddhist Publication Society |year=1993 |isbn=955-24-0103-8 |editor-last=Bodhi |location=Kandy, Sri Lanka |page=260 |oclc=33088951 |quote="Thus as fourfold the Tathagatas reveal the ultimate realities-consciousness, mental factors, matter, and Nibbana."}}</ref>

Thanissaro Bhikkhu (1997) renders an extract of Shakyamuni Buddha’s from Pali into English thus:
{{blockquote|Just as a skilled butcher or his apprentice, having killed a cow, would sit at a crossroads cutting it up into pieces, the monk contemplates this very body — however it stands, however it is disposed — in terms of properties: ‘In this body there is the earth property, the liquid property, the fire property, & the wind property.’<ref>{{Cite web |title=Kayagata-sati Sutta |url=http://www.accesstoinsight.org/tipitaka/mn/mn.119.than.html |access-date=2009-01-30 |website=Majjhima Nikaya |page=119 |via=accesstoinsight.org}}</ref>}}

===Alchemy===
[[File:Vitriol.png|thumb|Seventeenth century alchemical emblem showing the four Classical elements in the corners of the image, alongside the tria prima on the central triangle]]
{{anchor|Elements in Medieval alchemy}}

The elemental system used in medieval [[Philosophy:Alchemy|alchemy]] was developed primarily by the anonymous authors of the Arabic works attributed to Pseudo [[Biography:Apollonius of Tyana|Apollonius of Tyana]].{{sfnp|Norris|2006|pp=43–65}} This system consisted of the four classical elements of air, earth, fire, and water, in addition to a new theory called the sulphur-mercury theory of metals, which was based on two elements: [[Chemistry:Sulfur|sulphur]], characterizing the principle of combustibility, "the stone which burns"; and [[Chemistry:Mercury (element)|mercury]], characterizing the principle of metallic properties. They were seen by early alchemists as idealized expressions of irreducible components of the [[Astronomy:Universe|universe]]<ref>{{Cite book |last=Clulee |first=Nicholas H. |title=John Dee's Natural Philosophy |publisher=Routledge |year=1988 |isbn=978-0-415-00625-5 |pages=97}}</ref> and are of larger consideration within philosophical alchemy.

The three metallic principles—sulphur to flammability or combustion, mercury to volatility and stability, and [[Chemistry:Salt|salt]] to solidity—became the ''tria prima'' of the Swiss alchemist [[Biography:Paracelsus|Paracelsus]]. He reasoned that Aristotle's four element theory appeared in bodies as three principles. Paracelsus saw these principles as fundamental and justified them by recourse to the description of how wood burns in fire. Mercury included the cohesive principle, so that when it left in smoke the wood fell apart. Smoke described the volatility (the mercurial principle), the heat-giving flames described flammability (sulphur), and the remnant ash described solidity (salt).{{sfnp|Strathern|2001|p=79}}

{{Main|Philosophy:Godai (Japanese philosophy)}}

{{wipe|Japan}}ese traditions use a set of elements called the {{lang|ja|五大}} (''godai'', literally "five great"). These five are [[Unsolved:Earth (classical element)|earth]], [[Chemistry:Water (classical element)|water]], [[Unsolved:Fire (classical element)|fire]], wind/air, and [[Philosophy:Aether (classical element)|void]]. These came from Indian [[Philosophy:Vastu shastra|Vastu shastra]] philosophy and Buddhist beliefs; in addition, the [[Philosophy:Wuxing (Chinese philosophy)|classical Chinese elements]] ({{lang|ja|五行}}, ''wu xing'') are also prominent in Japanese culture, especially to the influential Neo-Confucianists during the medieval Edo period.<ref>{{Cite web |date=2022-02-22 |title=Encountering the '5 elements' in Japan's national parks |url=https://www.nationalgeographic.com/travel/article/paid-content-encountering-the-five-elements-in-japans-national-parks |archive-url=https://web.archive.org/web/20220223012427/https://www.nationalgeographic.com/travel/article/paid-content-encountering-the-five-elements-in-japans-national-parks |url-status=dead |archive-date=23 February 2022 |access-date=2023-05-07 |website=Travel |language=en}}</ref>

The [[Religion:Islamic philosophy|Islamic philosophers]] [[Biography:Al-Kindi|al-Kindi]], [[Biography:Avicenna|Avicenna]] and [[Biography:Fakhr al-Din al-Razi|Fakhr al-Din al-Razi]] followed [[Biography:Aristotle|Aristotle]] in connecting the four elements with the four natures heat and cold (the active force), and dryness and moisture (the recipients).<ref name="rafati">{{Cite journal |last=Rafati |first=Vahid |title=Lawh-i-Hikmat: The Two Agents and the Two Patients |url=http://bahai-library.com/rafati_hikmat_agents_patients |journal='Andalib |volume=5 |pages=29–38 |number=19}}</ref>

=== Native American tradition ===
The medicine wheel is a sacred symbol across many Indigenous American cultures that signifies Earth's boundary and all the knowledge of the universe. It depicts [[Cardinal direction|the four cardinal directions]], the path of the sun, the four seasons and the four sacred medicines. Each element is also represented by a color that signifies that four races of humans.<ref>{{Cite web |title=Medicine Wheel – CPN Cultural Heritage Center |url=https://www.potawatomiheritage.com/encyclopedia/medicine-wheel/ |access-date=2023-05-07 |language=en}}</ref><ref>{{Cite web |title=The Medicine Wheel (U.S. National Park Service) |url=https://www.nps.gov/articles/000/the-medicine-wheel.htm |access-date=2023-05-07 |website=www.nps.gov |language=en}}</ref>

*'''Earth''' (South) represents the youth cycle, summer, the Indigenous race, and [[Biology:Juniperus virginiana|cedar]] medicine.
*'''Fire''' (East) represents the birth cycle, spring, the Asian race, and [[Biology:Tobacco|tobacco]] medicine.
*'''Wind/Air''' (North) represents the elder cycle, winter, the European race, and [[Biology:Hierochloe odorata|sweetgrass]] medicine.
* '''Water''' (West) represents the adulthood cycle, autumn, the African race, and [[Biology:Salvia apiana|sage]] medicine.

The medicine wheel symbol is a modern invention dating to approximately 1972, with these descriptions and associations being a later addition. The associations with the classical elements are not grounded in traditional Indigenous teachings and the symbol has not been adopted by all Indigenous American nations.<ref name="Shaw">{{cite magazine |last=Shaw |first=Christopher |date=August 1995 |title=A Theft of Spirit? |url=https://thetrackingproject.org/a-theft-of-spirit/ |magazine=New Age Journal |location= |publisher= |access-date=28 April 2021}}</ref><ref name="Jung">{{cite web |last1=Thomason |first1=Timothy C |title=The Medicine Wheel as a Symbol of Native American Psychology |url=https://www.jungpage.org/learn/articles/culture-and-psyche/908-the-medicine-wheel-as-a-symbol-of-native-american-psychology |website=The Jung Page |publisher=The Jung Center of Houston |access-date=28 April 2021 |date=27 October 2013}}</ref><ref>{{cite web |last1=Chavers |first1=Dean |title=5 Fake Indians: Checking a Box Doesn't Make You Native |url=https://indiancountrytoday.com/archive/5-fake-indians-checking-a-box-doesnt-make-you-native |website=Indian Country Today |access-date=28 April 2021 |date=15 October 2014}}</ref><ref name="Beyer">{{cite web |last1=Beyer |first1=Steve |title=Selling Spirituality |url=https://www.singingtotheplants.com/2008/02/selling-spirituality/ |website=Singing to the Plants |access-date=28 April 2021 |date=3 February 2008}}</ref><ref name="Bear">{{cite book |last1=Bear Nicholas |first1=Andrea |editor1-last=Hulan |editor1-first=Renée |editor2-last=Eigenbrod |editor2-first=Renate |title=Aboriginal Oral Traditions: Theory, Practice, Ethics |date=April 2008 |publisher=Fernwood Pub Co Ltd |location=Halifax, NS |isbn=9781552662670 |pages=7–43 |chapter=The Assault on Aboriginal Oral Traditions: Past and Present}}</ref>

===Chemical element===

The [[Philosophy:Physics (Aristotle)|Aristotelian tradition]] and medieval [[Philosophy:Alchemy|alchemy]] eventually gave rise to modern [[Chemistry:Chemistry|chemistry]], scientific theories and new taxonomies. By the time of [[Biography:Antoine Lavoisier|Antoine Lavoisier]], for example, a [[Chemistry:History of the periodic table#Antoine-Laurent de Lavoisier|list of elements]] would no longer refer to classical elements.<ref>{{Cite book |last=Lavoisier |first=Antoine |url=http://web.lemoyne.edu/~giunta/index.html |title=Classic Chemistry |editor-last=Giunta |editor-first=Carmen |chapter=Elements of Chemistry |chapter-url=http://web.lemoyne.edu/~giunta/lavtable.html}}</ref> Some modern scientists see a parallel between the classical elements and the four [[Physics:State of matter|states of matter]]: [[Physics:Solid|solid]], [[Physics:Liquid|liquid]], [[Physics:Gas|gas]] and weakly ionized [[Physics:Plasma|plasma]].<ref>{{Citation |last=Kikuchi |first=Mitsuru |title=Frontiers in Fusion Research: Physics and Fusion |page=12 |year=2011 |place=London |publisher=Springer Science and Business Media |isbn=978-1-84996-411-1 |quote=Empedocles (495–435 BC) proposed that the world was made of earth, water, air, and fire, which may correspond to solid, liquid, gas, and weakly ionized plasma. Surprisingly, this idea may catch the essence.}}</ref>

Modern science recognizes classes of [[Physics:Elementary particle|elementary particle]]s which have no substructure (or rather, particles that are not made of other particles) and composite particles having substructure (particles made of other particles).

Western [[Unsolved:Astrology|astrology]] uses the four [[Unsolved:Astrology and the classical elements|classical elements]] in connection with astrological charts and horoscopes. The twelve signs of the [[Astronomy:Zodiac|zodiac]] are divided into the four elements: Fire signs are Aries, Leo and Sagittarius, Earth signs are Taurus, Virgo and Capricorn, Air signs are Gemini, Libra and Aquarius, and Water signs are Cancer, Scorpio, and Pisces.{{sfnp|Tester|1999|pp=59–61, 94}}

===Criticism===
The Dutch historian of science [[Biography:Eduard Jan Dijksterhuis|Eduard Jan Dijksterhuis]] writes that the theory of the classical elements "was bound to exercise a really harmful influence. As is now clear, Aristotle, by adopting this theory as the basis of his interpretation of nature and by never losing faith in it, took a course which promised few opportunities and many dangers for science."{{sfnp|Dijksterhuis|1969|p=71}} [[Biography:Bertrand Russell|Bertrand Russell]] says that Aristotle's thinking became imbued with almost biblical authority in later centuries. So much so that "Ever since the beginning of the seventeenth century, almost every serious intellectual advance has had to begin with an attack on some Aristotelian doctrine".{{sfnp|Russell|1991|p=173}}
