Kircher and species

description

Few ideas in biology are regarded as more representing the state of the world than "species", and yet the original motivations for developing the notion in the 17th century were religious, in the work of Athanasius Kircher (c1602–1680), the Jesuit polymath. Prior to him, the use of the word "species" was interchangeable with "genus" in natural history. In order to accommodate all the "kinds" (species) of quadrupeds and birds on the Ark, in his tractate De Arca Noë, Kircher used several strategies, including eliminating those species that spontaneously generated (worms, insects and spiders), and those which were formed from hybridisation (such as giraffes, hyenas and several fabulous creatures). Kircher stands at the cusp of modern natural history evolving out of the bestiary tradition, and De Arca Noë was a serious attempt at natural history within the confines of his set problem, with many woodcuts of the organisms concerned. His work informed Bishop John Wilkins, the English polymath, as he constructed a classification of all possible concepts, and to this end he employed John Ray to draw up the lists of species in his Essay toward a real character and a philosophical language as part of the Universal Language Project. Ray was chided by his colleagues, and so he commenced an empirical list of species, in the course of which he presented the first truly biological conception of the term. I will then cover the subsequent history of the idea through to the Enlightenment, including the question of whether or not species were real or mere constructs of human thought.

Kircher and species

The prescientific notion of species

Species, the term

๏ Just an ordinary Latin word๏ Used in technical and ordinary senses

Logical and philosophical uses (appearances, predicates)

If a Latin writer wishes to talk about a “kind”, they would use species or genus

๏ Which the translators of the Vulgate did.

๏ Genus from gens (family or stock)

Cannot assume that because one writer (Aristotle as translated) uses the term species they apply it to “our” species.

Species: The particular thing among many to which the looks are turned; hence, a particular sort, kind, or quality, a species.

Genus: Of an assemblage of objects (persons, animals, plants, inanimate or abstract things) which are related or belong together in consequence of a resemblance in natural qualities; a race, stock,class, sort, species, kind.

Kircher and the problem of kinds

Early scientific revolution

Jesuit polymath, Athanasius Kircher published De Arca Noë in 1675

Needs to fit all the “kinds” (Latin: species) on the Ark

c310 quadrupeds and several score bird species on the Ark

Proposes thousands of species of animals by hybridisation or spontaneously generated

Athanasius Kircher c.1602–1680

Page 35: The theological and philosophical origins of the concept of biological species from Athanasius Kircher to John Ray

Kircher and species

The origins of species that were not on the Ark

Hybrids and geographical varieties

๏ Idea found in Aristotle’s History of Animals

๏ Repeated in Pliny’s Natural History, and thence by all educated Europeans

๏ The giraffe, for example, was held to be a hybrid of the camel and leopard (hence camelopard)

Page 36: The theological and philosophical origins of the concept of biological species from Athanasius Kircher to John Ray

Kircher and species

As a general rule, wild animals are at their wildest in Asia, their boldest in Europe and most diverse in form in Libya [Africa]; in fact, there is an old saying. ‘Always something fresh in Libya.’

It would appear that in that country animals of diverse species [homophulê] meet, on account of the rainless climate, at the watering places, and they pair together; and that such pairs breed if they be nearly of the same size and have periods of gestation of the same length. For they are tamed down in their behaviour towards each other by extremity of thirst. ... Elsewhere also offspring are born to heterogeneous pairs; thus in Cyrene the wolf and the bitch will couple and breed; and the Laconian hound is a cross between the fox and the dog. They say that the Indian dog is a cross between the tiger and the bitch, not the first cross, but a cross in the third generation; for they say that the first cross is a savage creature. They take the bitch to a lonely spot and tie her up—and many are eaten, unless the beast is eager to mate. [History of Animals VIII.28 606b16–607a7]

Aristotle on hybrids

Page 37: The theological and philosophical origins of the concept of biological species from Athanasius Kircher to John Ray

Kircher and species

Pliny on hybridsThe noble appearance of the lion is more especially to be seen in that species which has the neck and shoulders covered with a mane, which is always acquired at the proper age by those produced from a lion; while, on the other hand, those that are the offspring of the pard, are always without this distinction. The female also has no mane. The sexual passions of these animals are very violent, and render the male quite furious. This is especially the case in Africa, where, in consequence of the great scarcity of water, the wild beasts assemble in great numbers on the banks of a few rivers. This is also the reason why so many curious varieties of animals are produced there, the males and females of various species coupling promiscuously with each other. Hence arose the saying, which was common in Greece even, that “Africa is always producing something new.” [Natural History VIII 17.42]

Page 38: The theological and philosophical origins of the concept of biological species from Athanasius Kircher to John Ray

Kircher and species

Abbott on hybrids… this may be said of Africke in generall, that it bringeth forth store of all sorts of wild Beasts, as Elephants, Lyons, Panthers, Tygers, and the like: yea, according to the Proverbe, Africa semper aliquid apportat novi; Often times new and strange shapes of Beasts are brought forth there [Africa]: the reason whereof is, that the Countrie being hott and full of Wildernesses, which haue in them litle water, the Beastes of all sortes are enforced to meet at those few watering places that be, where often times contrary kinds haue conjunction the one with the other: so that there ariseth new kinds of species, which take part of both. Such a one is the Leopard, begotten of the Lyon and the Beast called the Pardu, and somewhat resembling either of them. [A briefe description of the whole world, 1599]

Spontaneous generationThe standard view was that simple organisms would generate spontaneously (generatio equivoca), but also many complex organisms too

๏ Augustine interpreted Genesis that way (De Genesi ad Litteram)

๏ Great Chain of Being: no clear boundary between living and nonliving

๏ Kircher thought insects, worms, molluscs would form spontaneously

Lull, Logica Nova, 1512

Kircher’s explanatory targetSo Kircher’s problem reduced down to accommodating the “large” or “complex” animals on the Ark

For this he needed to have what in logic was called an infimae species, the lowest kind

Then he could calculate the size and arrangements on the Ark:

Clearly Kircher is trying to keep up with the latest natural history in a period in which such information is becoming unmanageable

๏ Most of his “species” are from Gesner, particularly the birds

๏ However, he represents the fin de siècle of an older tradition that spans the bestiary tradition and modern natural history

Page 65: The theological and philosophical origins of the concept of biological species from Athanasius Kircher to John Ray

Kircher and species

Naturalists used the term “species” in an ordinary way from the 1500s (Gesner, Bauhin, Androvani)

Shortly before Kircher’s Arca Noë, Bp John Wilkins (no close relation) wrote his Essay toward a real character and a philosophical language (1668).

๏ Attempted to categorise all things in an artificial language (The Universal Language Project)

๏ Included lists of species, drawn up by the botanist John Ray

๏ Forced all species into predetermined linguistic categories

Later (1686) wrote that he needed a definition of the kinds/species to justify his work

In order that an inventory of plants may be begun and a classification of them correctly established, we must try to discover criteria of some sort for distinguishing what are called “species”. After long and considerable investigation, no surer criterion for determining species has occurred to me than the distinguishing features that perpetuate themselves in propagation from seed. Thus, no matter what variations occur in the individuals or the species, if they spring from the seed of one and the same plant, they are accidental variations and not such as to distinguish a species ... Animals likewise that differ specifically preserve their distinct species permanently; one species never springs from the seed of another nor vice versa.

Species has a “life” after Ray, which leads to modern debates directly.

Obligatory Darwin comment

Philosophers and historians of biology are required by the Guild Rules to mention Darwin

Was Mayr right? Did Darwin change our notion of species?

No.
