After
Louis Agassiz came to the United States he became a prolific writer in what has been later termed the genre of scientific racism. Agassiz was specifically a believer and advocate in polygenism, that races came from separate origins (specifically separate creations), were endowed with unequal attributes, and could be classified into specific climatic zones, in the same way he felt other animals and plants could be classified.
In recent years, critics have cited Agassiz's racial theories, arguing that these now-unpopular views tarnish his scientific record. This has occasionally prompted the renaming of landmarks, schoolhouses, and other institutions which bear the name of Agassiz (which abound in Massachusetts). Opinions on these events are often torn, given his extensive scientific legacy in other areas. On September 9, 2007 the Swiss government acknowledged the "racist thinking" of Agassiz but declined to rename the Agassizhorn summit.
Agassiz was never a supporter of slavery, and claimed his views had nothing to do with politics. Agassiz was influenced by philosophical idealism and the scientific work of Georges Cuvier. According to Agassiz, genera and species were ideas in the mind of God; their existence in God’s mind prior to their physical creation meant that God could create humans as one species yet in several distinct and geographically separate acts of creation. According to Agassiz, there is one species of humans but many different creations of races.
Agassiz was a creationist who believed nature had order because God has created it directly, and Agassiz viewed his career in science as a search for ideas in the mind of the creator expressed in creation. Agassiz denied that migration and adaptation could account for the geographical age or any of the past. Adaptation takes time; in an example, Agassiz questioned how plants or animals could migrate through regions they were not equipped to handle. According to Agassiz the conditions in which particular creatures live “are the conditions necessary to their maintenance, and what among organized beings is essential to their temporal existence must be at least one of the conditions under which they were created”.
In his work he noted similarities of distribution of like species in different geological eras, a phenomenon clearly not the result of migration. Agassiz questioned how fish of the same species live in lakes well separated with no joining waterway, Agassiz concluded they were created at both locations. According to Agassiz the intelligent adaptation of creatures to their environments testified to an intelligent plan. The conclusions of his studies lead him to believe that whichever region each animal was found in, was created there “animals are naturally autochthones wherever they are found”. After further research he later extended this idea to humans, which became to be known as his theory of polygenism.
According to Agassiz’s theory of polygenism animals, plants and humans were all created in “special provinces” each having distinct populations of species created in and for that province. Agassiz claimed plants, animals and humans did not originate in pairs but were created in large numbers. According to Agassiz, the different races were created in different provinces, each race was indigenous to the province it was created in, he cited evidence from Egyptian monuments to prove that fixity of racial types had existed for at least five millennia. According to Agassiz’s theory of polygenism all species are fixed, including all the races of humans and species do not evolve into other species.
Agassiz like other polygenists believed the Book of Genesis recounted the origin of the white race only and that the animals and plants in the Bible refer only to those species proximate and familiar to Adam and Eve. Agassiz, Josiah Clark Nott, and other polygenists such as George Gliddon, believed that the original Hebrew form of the name Adam came from a Biblical Hebrew consonantal root referring to redness, so that the name can be interpreted to mean "to show red in the face" or "blusher"; since only light skinned people can blush, then the biblical Adam must be the Caucasian race. Agassiz believed that the writers of the Bible only knew of local events, for example was a local event only known to the regions that were populated by ancient Hebrews, Agassiz claimed the writers of the Bible did not know about any events other than what was going on in their own region and their intermediate neighbors.
According to Agassiz the provinces that the different races were created in included Western American Temperate (the indigenous peoples west of the Rockies); Eastern American Temperate (east of the Rockies); Tropical Asiatic (south of the Himalayas); Temperate Asiatic (east of the Urals and north of the Himalayas); South American Temperate (South America); New Holland (Australia); Arctic (Alaska and Arctic Canada); Cape of Good Hope (South Africa); and American Tropical (Central America and the West Indies).
Stephen Jay Gould said that Agassiz's theories sprang from an initial revulsion in his encounters with African-Americans upon moving to the United States. Even though Agassiz was a believer in polygenism he rejected racism and supported the notion of a spiritualized human unity. He claimed human polygenism did not undermine the spiritual commonality of all people, even though each race was physically diverse. The physical descent was irrelevant to the spiritual descent of humanity according to Agassiz Agassiz believed God had made all men equal:
Those intellectual and moral qualities which are so eminently developed in civilized society, but which equally exist in the natural dispositions of all human races, constituting the higher unity among men, making them all equal before God.
Agassiz also opposed monogenism and evolution, he claimed that the theory of evolution reduced the wisdom of God to an impersonal materialism. Species, in their natures and geographical distribution, are direct expressions of the intelligence and will of God, not the results of blind chance. Agassiz believed evolution was an insult to the wisdom and will of God. Agassiz’s polygenism theory was accepted by a number of Protestants and scientists. For example Nathaniel Shaler who had studied under Agassiz at Harvard was a believer in Agassiz's polygenism.
