Themicrocosm–macrocosm analogy (or, equivalently,macrocosm–microcosm analogy) refers to a historical view which posited a structural similarity between thehuman being (themicrocosm, i.e., thesmall order or thesmall universe) and thecosmos as a whole (themacrocosm, i.e., thegreat order or thegreat universe).[b] Given this fundamental analogy, truths about the nature of the cosmos as a whole may be inferred from truths about human nature, and vice versa.[1]
One important corollary of this view is that the cosmos as a whole may be considered to be alive, and thus to have a mind or soul (theworld soul), a position advanced byPlato in hisTimaeus.[2] Moreover, this cosmic mind or soul was often thought to be divine, most notably by theStoics and those who were influenced by them, such as the authors of theHermetica.[3] Hence, it was sometimes inferred that the human mind or soul was divine in nature as well.
In contemporary usage, the terms microcosm and macrocosm are also employed to refer to any smaller system that is representative of a larger one, and vice versa.
Medieval philosophy was generally dominated byAristotle, who – despite having been the first[16] to coin the term "microcosm" – had posited a fundamental and insurmountable difference between the region below the Moon (thesublunary world, consisting of thefour elements) and the region above the Moon (the superlunary world, consisting of afifth element). Nevertheless, the microcosm–macrocosm analogy was adopted by a wide variety of medieval thinkers working in different linguistic traditions: the concept of microcosm was known inArabic asʿālam ṣaghīr, inHebrew asolam katan, and inLatin asmicrocosmus orminor mundus.[17] The analogy was elaborated byalchemists such as those writing under the name ofJabir ibn Hayyan (c. 850–950 CE),[18] by the anonymousShi'ite philosophers known as theIkhwān al-Ṣafāʾ ("The Brethren of Purity",c. 900–1000),[19] by Jewish theologians and philosophers such asIsaac Israeli (c. 832 – c. 932),Saadia Gaon (882/892–942),Ibn Gabirol (11th century), andJudah Halevi (c. 1075–1141),[20] byVictorine monks such asGodfrey of Saint Victor (born 1125, author of a treatise calledMicrocosmus), by theAndalusian mysticIbn Arabi (1165–1240),[21] by the German cardinalNicholas of Cusa (1401–1464),[22] and by numerous others.
The revival ofHermeticism andNeoplatonism in theRenaissance, both of which had reserved a prominent place for the microcosm–macrocosm analogy, also led to a marked rise in popularity of the latter. Some of the most notable proponents of the concept in this period includeMarsilio Ficino (1433 – 1499),Heinrich Cornelius Agrippa (1486–1535),Francesco Patrizi (1529–1597),Giordano Bruno (1548–1600), andTommaso Campanella (1568–1639).[23] It was also central to the new medical theories propounded by the Swiss physicianParacelsus (1494–1541) and his manyfollowers, most notablyRobert Fludd (1574–1637).[24]Andreas Vesalius (1514–1564) in his anatomy textDe fabrica wrote that the human body "in many respects corresponds admirably to the universe and for that reason was called the little universe by the ancients."[25]
Analogies between microcosm and macrocosm are found throughout the history ofJewish philosophy. According to this analogy, there is a structural similarity between the human being (themicrocosm, fromKoinē Greek:μικρὸς κόσμος,romanized: mikròs kósmos,Hebrew:עולם קטן,romanized: ʻolam qāṭān,lit. 'small universe') and thecosmos as a whole (themacrocosm, from Koinē Greek:μακρὸς κόσμος,romanized: makròs kósmos,lit. 'great universe').[26]
The view was elaborated by the Jewish philosopherPhilo (c. 20 BCE–50 CE), who adopted it fromHellenistic philosophy.[27] Similar ideas can also be found in earlyrabbinical literature. In the Middle Ages, the analogy became a prominent theme in the works of most Jewish philosophers.
In theAvot de-Rabbi Natan (compiled c. 700–900), human parts are compared with parts belonging to the larger world: the hair is like a forest, the lungs like the wind, the loins like counsellors, the stomach like a mill, etc.[28]
Nevertheless, the analogy was already in use by earlier Jewish philosophers. In his commentary on theSefer Yetzirah ("Book of Creation"),Saadia Gaon (882/892–942) put forward a set of analogies between the cosmos, theTabernacle, and the human being.[32] Saadia was followed in this by a number of later authors, such as Bahya ibn Paquda, Judah Halevi, and Abraham ibn Ezra.[32]
Whereas the physiological application of the analogy in the rabbinical workAvot de-Rabbi Natan had still been relatively simple and crude, much more elaborate versions of this application were given by Bahya ibn Paquda and Joseph ibn Tzaddik (in hisSefer ha-Olam ha-Katan, "Book of the Microcosm"), both of whom compared human parts with the heavenly bodies and other parts of the cosmos at large.[33]
The analogy was linked to the ancient theme of "know thyself" (Greek: γνῶθι σεαυτόν,gnōthi seauton) by the physician and philosopherIsaac Israeli (c. 832–932), who suggested that by knowing oneself, a human being may gain knowledge of all things.[32] This theme of self-knowledge returned in the works of Joseph ibn Tzaddik, who added that in this way humans may come to know God himself.[32] The macrocosm was also associated with the divine by Judah Halevi, who saw God as the spirit, soul, mind, and life that animates the universe, while according toMaimonides (1138–1204), the relationship between God and the universe is analogous to the relationship between the intellect and the human being.[32]

^The terms microcosm and macrocosm derive fromancient Greekμικρὸς κόσμος (mikròs kósmos) andμακρὸς κόσμος (makròs kósmos), which may mean 'small universe' and 'great universe', but whose primary meaning is 'small order' and 'great order', respectively (seewiktionary; cf.Allers 1944, pp. 320–321, note 5).
