The microcosm–macrocosm analogy (or, equivalently, macrocosm–microcosm analogy) refers to a historical view which posited a structural similarity between the human being (the microcosm, i.e., the small order or the small universe) and the cosmos as a whole (the macrocosm, i.e., the great order or the great 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 (the world soul), a position advanced by Plato in his Timaeus.[2] Moreover, this cosmic mind or soul was often thought to be divine, most notably by the Stoics and those who were influenced by them, such as the authors of the Hermetica.[3] Hence, it was sometimes inferred that the human mind or soul was divine in nature as well.
Apart from this important psychological and noetic (i.e., related to the mind) application, the analogy was also applied to human physiology.[4] For example, the cosmological functions of the seven classical planets were sometimes taken to be analogous to the physiological functions of human organs, such as the heart, the spleen, the liver, the stomach, etc.[c]
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.
History
Antiquity
Among ancient Greek and Hellenistic philosophers, notable proponents of the microcosm–macrocosm analogy included Anaximander (c. 610 – c. 546 BCE),[8]Plato (c. 428 or 424 – c. 348 BCE),[9] the Hippocratic authors (late 5th or early 4th century BCE and onwards),[10] and the Stoics (3rd century BCE and onwards).[11] In later periods, the analogy was especially prominent in the works of those philosophers who were heavily influenced by Platonic and Stoic thought, such as Philo of Alexandria (c. 20 BCE – c. 50 CE),[12] the authors of the early Greek Hermetica (c. 100 BCE–300 CE),[13] and the Neoplatonists (3rd century CE and onwards).[14] The analogy was also employed in late antique and early medieval religious literature, such as in the Bundahishn, a Zoroastrian encyclopedic work, and the Avot de-Rabbi Nathan, a Jewish Rabbinical text.[15]
Middle Ages
Medieval philosophy was generally dominated by Aristotle, 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 (the sublunary world, consisting of the four elements) and the region above the Moon (the superlunary world, consisting of a fifth 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 in Arabic as ʿālam ṣaghīr, in Hebrew as olam katan, and in Latin as microcosmus or minor mundus.[17] The analogy was elaborated by alchemists such as those writing under the name of Jabir ibn Hayyan (c. 850–950 CE),[18] by the anonymous Shi'ite philosophers known as the Ikhwān al-Ṣafāʾ ("The Brethren of Purity", c. 900–1000),[19] by Jewish theologians and philosophers such as Isaac Israeli (c. 832 – c. 932), Saadia Gaon (882/892–942), Ibn Gabirol (11th century), and Judah Halevi (c. 1075–1141),[20] by Victorine monks such as Godfrey of Saint Victor (born 1125, author of a treatise called Microcosmus), by the Andalusian mystic Ibn Arabi (1165–1240),[21] by the German cardinal Nicholas of Cusa (1401–1464),[22] and by numerous others.
Renaissance
The revival of Hermeticism and Neoplatonism in the Renaissance, 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 include Marsilio Ficino (1433 – 1499), Heinrich Cornelius Agrippa (1486–1535), Francesco Patrizi (1529–1597), Giordano Bruno (1548–1600), and Tommaso Campanella (1568–1639).[23] It was also central to the new medical theories propounded by the Swiss physician Paracelsus (1494–1541) and his many followers, most notably Robert Fludd (1574–1637).[24]Andreas Vesalius (1514–1564) in his anatomy text De 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 of Jewish philosophy. According to this analogy, there is a structural similarity between the human being (the microcosm, from Koinē Greek: μικρὸς κόσμος, romanized: mikròs kósmos, Hebrew: עולם קטן, romanized: ʻolam qāṭān, lit. 'small universe') and the cosmos as a whole (the macrocosm, from Koinē Greek: μακρὸς κόσμος, romanized: makròs kósmos, lit. 'great universe').[26]
The view was elaborated by the Jewish philosopher Philo (c. 20 BCE–50 CE), who adopted it from Hellenistic philosophy.[27] Similar ideas can also be found in early rabbinical literature. In the Middle Ages, the analogy became a prominent theme in the works of most Jewish philosophers.
Rabbinical literature
In the Avot 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 the Sefer Yetzirah ("Book of Creation"), Saadia Gaon (882/892–942) put forward a set of analogies between the cosmos, the Tabernacle, 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 work Avot 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 his Sefer 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 philosopher Isaac 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 to Maimonides (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 from ancient Greekμικρὸς κόσμος (mikròs kósmos) and μακρὸς κόσμος (makròs kósmos), which may mean 'small universe' and 'great universe', but whose primary meaning is 'small order' and 'great order', respectively (see wiktionary; cf. Allers 1944, pp. 320–321, note 5).

The terms also occur in medieval Arabic sources as ʿālam ṣaghīr and in medieval Latin sources as microcosmus or minor mundus (see Kraemer 2007; on the Latin terminology, see Finckh 1999, p. 12).
^The Epistles of the Brethren of Purity were of much less importance to Maimonides (1138–1204), who also ignored Joseph ibn Tzaddik's work on the microcosm–macrocosm analogy; see Kraemer 2007.
