Abstract
We deliver a "keyword" account of the term life form as it has been used in natural philosophy and biology over the last two hundred years, beginning with its appearance in German as Lebensform. We argue that life form has, since its earliest enunciations, pointed to a space of possibility within which life might take shape, but that the way that space is imagined and theorized in biology has transformed substantially; life form originated as a term referring to idealized, aesthetic possibilities, then transformed to describe biogeographic and evolutionary potentialities, and today, in the age of synthetic biology and astrobiology, has come to signal conjectural and future possibilities.

- Comparative anatomist Johann Friedrich Blumenbach's 1781 theory of the Bil- dungstrieb (building-drive) posited a formative impulse in organisms "respon- sible for reproduction, nourishment, and restoration of parts"; Robert J. Richards, The Romantic Conception of Life: Science and Philosophy in the Age of Goethe (Chicago, 2002), 219. Bildungstrieb was for Blumenbach "a teleological cause fully resident in nature"; Richards, Romantic Conception, 221, "a secondary cause yielding immediate effects and itself . . . the effect of some hidden primary cause" (277). Blumenbach imparted to his many students, including Alexander von Humboldt, Karl Friedrich Kielmeyer, and Gottfried Reinhold Treviranus, a morphologically inflected Kantian philosophy in which scientific observation and aesthetic judgment were often entangled; see Robert J. Richards, The Tragic Sense of Life: Ernst Haeckel and the Struggle over Evolutionary Thought (Chicago, 2008).

- Historian of biology Joan Steigerwald (personal communication) writes that "the Historisches Wörterbuch der Philosophie (Historical Dictionary of Philosophy) focuses entirely on the psychological, religious, philosophical and social uses of Lebensform, starting with Friedrich Schleiermacher (Psychol. Sämtl. Werke [1835-64] 3:6, 334 f), then W. Wundt (Ethik 1886, 135f), and then moving on to 20th century figures." This lineage of Lebensform takes us up to Ludwig Wittgenstein, who in his Philosophical Investigations (1953; reprint, New York, 1958) used Lebensform-always translated as "form of life" in English-to refer to a frame of reference within which linguistic action becomes meaningful.

- Haeckel's attention to symmetry, arrangement, and form strongly influenced Surrealist and Bauhaus artists, among them Max Ernst, Wassily Kandinsky, and Paul Klee. Klee wrote that "form is the end, death. Form-giving is movement, action. Form-giving is life"; quoted in Mitchell Whitelaw, Metacreation: Art and Artificial Life (Cambridge, MA, 2004), 15, and "Starting from nature, the stu- dents will perhaps arrive at their own forms, and one day be themselves nature, construct like nature"; quoted in Paul Rabinow, Marking Time: On the Anthropol- ogy of the Contemporary (Princeton, 2008), 101. See also David Brody, "Ernst Haeckel and the Microbial Baroque," Cabinet, no. 7 (Summer 2002): 25-27.
- Klee's demarcation of form and form-giving hearkens back to Schelling and the Jena Romantics, who believed that "nature, in both its inorganic and organic forms, is that 'middle' [das Mittel] between productivity and product, between the free and the fixed, the middle that is ever in a state of formation";
- Steigerwald, "Cultural Enframing," 483. Schelling and the Jena Romantics fur- ther claimed that the artistic sensibility could succeed where rational observation failed, spanning the gulf between life's inner forces and outer manifestations by "comprehend[ing] how in natural products particular material is informed by a universal form" (484). The art connection suggests that another lineage for life form may be in life drawing. One touchstone for such a lineage may be Allan Harrison, "An Analysis of the Life-Form in Art," Transactions of the American Philosophical Society 15, no. 2 (1875): 279-350.

- This is the case even if Darwin's theory is being argued against. In 1878, Alexan- der Wilford Hall, a Methodist minister from New York, published The Problem of Human Life: Embracing the "Evolution of Sound" and "Evolution Evolved" (New York), in which he argues against both Darwinian theory and the wave theory of sound; see M. C. M. Wright, "A Short History of Bad Acoustics," Journal of the Acoustical Society of America 120, no. 4 (2006): 1807-15. He wrote, "As the physical structure contains not only the different organs of the body but an almost infi- nite number and variety of separate molecules and units of real organic atoms, so the vital organism within each living creature contains not only the intrinsic life-form of the specific being it inhabits but is a veritable microcosm or a little universe of life-forms which include the intrinsic germs of all organic being [sic] wherever found"; Hall, Problem of Human Life, 415. Such a notion of natural his- tory, in which the earliest organism had all future organisms latent within it, is a throwback to earlier articulations of "evolution" by such figures as the Dutch insectologist Jan Swammerdam; Richards, Romantic Conception, 211.

(81) and "The discriminating circumstances revealed through the recent wonder- ful improvements in the telescope, if they make it more difficult to conceive that certain globes in our system are inhabited by forms of life at all resembling those with which we are familiar, render it more difficult still to doubt it as regards those others which are proved to resemble our globe very nearly in the physical circum- stances which specifically adapt it for human residence" (30).

While this is the earliest use of "life form" in sci- ence fiction literature that we could identify, "form of life" did appear in Romantic and Victorian gothic fiction, as for example in Mary Shelley's 1837 Falkner: "To the surgeon's eye, a human body sometimes presents itself merely as a mass of bones, muscles, and arteries-though that human body may contain a soul to emulate Shakespeare-and thus there are moments when the wretched dissect the forms of life-and contemplating only the outward semblance of events, wonder how so much power of misery, or the reverse, resides in what is after all but sleeping or waking"; Mary Wollstonecraft Shelley, The Novels and Selected Works of Mary Shelley (London, 1996), 7:280-81, and Bram Stoker's Drac- ula (London, 1897): "Despises the meaner forms of life altogether, though he dreads being haunted by their souls" (272). A use of "life form" preceding its appearance in science fiction appears in the writings of late nineteenth-and early twentieth-century spiritualist Sir Arthur Conan Doyle. Doyle wrote about the coagulation of ectoplasm into anthropomorphisms: "It is conceivable that the thinner emanation of the clairvoyant would extend far further than the R E P R E S E N TAT I O N S thick material ectoplasm, but have the same property of moulding itself into life, though the life forms would only be visible to the clairvoyant eye"; The Vital Message (New York, 1919), 150. Three years later, in 1922, Doyle would again employ the term, to speculate on the origin of fairies. He summarizes the theory of psychic researcher David Gow: "They are really life forms which have devel- oped along some separate line of evolution, and which for some morphological reason have assumed human shape in the strange way in which Nature repro- duces her types like the figures on the mandrake root or the frost ferns upon the window"; The Coming of the Fairies (Lincoln, NE, 2006), 148-49.

He was desperately worried that one day sentient life forms would forget how to do this. Only by counting could humans demonstrate their inde- pendence of computers." Ursula K. Le Guin employs the acronym HILF-"high intelligence life forms"-in several of her novels and short stories, treating it as a category cir- cumscribed both biologically and anthropologically. The titular protagonist of Rocannon's World is "a hilfer, an ethnologist of the High Intelligence Life Forms" (17), a sort of interstellar salvage ethnographer who carries the "Abridged Handy Pocket Guide to Intelligent Life-forms" (3). (Le Guin uses life form and life-form interchangeably.) Le Guin's almost Humboldtian use of life form as con- gruent with both custom and morphology is unsurprising, as Le Guin, daughter of anthropologist Alfred Kroeber, often draws upon the ethnographic genre. As she explained in an interview with the Guardian: "Claude Levi-Strauss has been a great source of fruitful irritation to my mind; so has Clifford Geertz"; "Chroni- cles of Earthsea" (2004), online at http://www.guardian.co.uk/books/2004/feb/ 09/sciencefictionfantasyandhorror.ursulakleguin. From Philip K. Dick, Galactic Pot-Healer (1969) (New York, 1994): "'What's a crumble?' he asked, when the robot monitor answered. . . .'On Rigel two it means a small life-form which scuttles-'" (19).
