Harari's larger contention is that our homocentric creed, devoted to human liberty and happiness, will be destroyed by the approaching post-humanist horizon.

Detroit: Charles Scribner's Sons, 2008. 465–467. Gale Virtual Reference Library. Web. 2 June 2014. He came up with the idea of homocentric spheres in order to explain the perceived inconsistent motions of the planets and to develop a uniform model for accurately calculating the movement of celestial objects.

The cosmological model of concentric (or homocentric) spheres, developed by Eudoxus, Callippus, and Aristotle, employed celestial spheres all centered on the Earth. In this respect, it differed from the epicyclic and eccentric models with multiple centers, which were used by Ptolemy and other mathematical astronomers until the time of Copernicus.

Al-Bitruji proposed a theory on planetary motion in which he wished to avoid both epicycles and eccentrics,Bernard R. Goldstein (March 1972). "Theory and Observation in Medieval Astronomy", Isis 63 (1), p. 39-47 [41]. and to account for the phenomena peculiar to the wandering stars, by compounding rotations of homocentric spheres.

Zubrin summed up this view: Richard Taylor more succinctly exemplified this point of view with the slogan, "move over microbe". Some critics label this argument as an example of anthropocentrism. These critics may view the homocentric view as not only geocentric but short-sighted, and tending to favour human interests to the detriment of ecological systems. They argue that an anthropocentrically driven approach could lead to the extinction of indigenous extraterrestrial life, or the Interplanetary contamination.

The Antikythera Mechanism was an analog computer from 150–100 BC designed to calculate the positions of astronomical objects. The Ancient Greeks developed astronomy, which they treated as a branch of mathematics, to a highly sophisticated level. The first geometrical, three-dimensional models to explain the apparent motion of the planets were developed in the 4th century BC by Eudoxus of Cnidus and Callippus of Cyzicus. Their models were based on nested homocentric spheres centered upon the Earth.

Chongli Hall () Chongli Hall was initially built from 1457 to 1464. It is a three-hall construction facing south and located on the head of the boat-shaped village, and is characterized by a unique two-homocentric squares courtyard in the middle. The pond in front of the gate is called "Up Water Pond" (or Shangshui Pond), which together with the building forms a fengshui pattern called "Zhuque" (firebird) – "Xuanwu" (dragon tortoise) (i.e. a spatial layout) and acts for fire prevention purpose.

To account for apparent anomalies in this view, such as the apparent retrograde motion of the planets, a system of deferents and epicycles was used. The planet was said to revolve in a small circle (the epicycle) about a center, which itself revolved in a larger circle (the deferent) about a center on or near the Earth.Koestler (1989), pp. 69-72 A complementary theory to Ptolemy's employed homocentric spheres: the spheres within which the planets rotated could themselves rotate somewhat.

Callippus, a contemporary of Eudoxus, attempted to improve his system by increasing the total number of homocentric spheres. He added two additional spheres for the sun and the moon as well as one additional sphere for Mars, Mercury, and Venus. These additional spheres were supposed to fix some of the calculation problems in Eudoxus’ original system. Callippus’ system was able to better predict the motions of certain celestial objects but his system still had many problems and was not able to account for many astronomical observations.

Little is known of the life of Bernard of Verdun, except that he was a Franciscan friar who may have been born in Verdun and lived in the second half of the thirteenth century. His most significant work was the Treatise on the Whole of Astronomy (Tractatus super totam astrologiam), in which he defended Ptolemy's theory of epicycles and eccentrics against al-Bitruji's system of homocentric spheres.Elena Hadravova and Petr Hadrava, "Bernard of Verdun," in Thomas Glick, Steven J. Livesey, and Faith Wallis, ed. Medieval Science, Technology, and Medicine: An Encyclopedia, New York: Routledge, 2005.

The layout of moraines forms homocentric ellipses in the land. The longer pivot of these ellipses agrees more or less with the axis NEE-SWW. However, this isn't an absolute rule for the region, as for example, the ellipses lying in the centre of the Szymbarskie Upland are oriented on the axis E-W. Both the arrangements of postglacial channel-type lakes and the waterway network have a similar arrangement to radial, reflecting arrangement of gashes of a domed structure area, with the direction however dominating the axis NNE-SWW.

None of his books have survived to the modern day and everything we know about his cosmological theories comes from the works of Aristotle and Simplicius. According to these works, Eudoxus’ model had twenty-seven homocentric spheres with each sphere explaining a type of observable motion for each celestial object. Eudoxus assigns one sphere for the fixed stars which is supposed to explain their daily movement. He assigns three spheres to both the sun and the moon with the first sphere moving in the same manner as the sphere of the fixed stars.

Instead, they accepted Aristotle's model and promoted the theory of homocentric spheres. Al-Bitruji is believed to have studied under Ibn Tufail and Bitruji's Book on Cosmology (Kitab fi al-hay'a) built on Ibn Tufail's work, as well as that of Ibn Rushd, Ibn Bajja, and Maimonides. The book's goal was "to overcome the physical difficulties inherent in the geometrical models of Ptolemy's Almagest and to describe the cosmos in agreement with Aristotelian or Neoplatonic physics," which it succeeded in doing to an extent. Bitruji's book set a precedent of criticizing the Almagest in future works in the field of astronomy.

In his essay "For the Last Time: Civilizations", he has also posited the binary opposition between "Islam and the West" as a major narrative strategy of raising a fictive centre for European modernity and lowering the rest of the world as peripheral to that centre. In Truth and Narrative, he has deconstructed the essentialist conception of Islam projected by Orientalists and Islamists alike. Instead he has posited, in what he calls a "polyfocal" conception of Islam, three competing discourses and institutions of authority – which he terms "nomocentric" (law-based), "logocentric" (reason-based) and "homocentric" (human-based) – vying for power and competing for legitimacy. The historical dynamics among these three readings of "Islam", he concludes, constitutes the moral, political and intellectual history of Muslims.

U.S. Highway 93 now features forty wildlife crossing structures. The project received the Transportation Planning Excellence Award from the Federal Highway Administration in 2008. Jones & Jones pioneered the habitat immersion approach to zoo design with the development of the gorilla and African savannah exhibits at Seattle’s Woodland Park Zoo (Hyson, 23; Hancocks, 118). In 1978, zoo director David Hancocks approached the firm for a master plan. Rather than the traditional arrangement of animal enclosures behind concrete walls and bars, Hancocks and his design team, led by Grant Jones, sought to recreate the animals’ natural habitat. The gorilla forest was developed in the first phase of the project: careful manipulation of landform, plants, and sight lines immersed not only the gorillas but also the visitors in the animals’ native habitat. The landscape immersion method has been described as “an astonishing departure from conventional zoo design because it reflected a pronounced shift in philosophy” from a homocentric to a biocentric view of the world (Hancocks, 118). The philosophy is now widespread (Hyson, 23), and since the late 1970s, Jones & Jones has developed master plans and specialized habitat designs for scores of zoos on four continents.
