Full textAbstract:
In this article we argue that Ernst Cassirer's philosophy of symbolic forms is an indispensible philosophical-anthropological companion to rhetoric. We propose that appropriating Cassirer's understanding of symbolic forms enables rhetoric to go beyond the dominant perspective of language oriented theory and fully commit to a widened understanding of rhetoric as the study of how social meaning is created, performed and transformed. To clearly bring out the thrust of our enlarged rhetorical-philosophical-anthropological approach we have structured our argument partly as a contrastive critique of Thomas A. Discenna's recent (Rhetorica 32/3; 2014) attempt to include Cassirer in the rhetorical tradition through a reading of the 1929 debate in Davos between Cassirer and Martin Heidegger; partly through a presentation of the aspects of Cassirer's thought that we find most important for developing a rhetorical-philosophical-anthropology of social meaning.

Full textAbstract:
This essay takes up a discussion concerning the 1929 debate between the philosophers Ernst Cassirer and Martin Heidegger by reading it as an instatiation of an ongoing dilemma within the field of rhetoric. I argue that the Davos meeting may be productively read through the lens of rhetorical theory and that such a reading can contribute to a more nuanced understanding of this event. The essay concludes by making a case for Cassirer's philosophy of symbolic forms as a normative ground for a rhetorical theory whose central purpose is to construct a decent, cultured, cosmopolitan, critical humanism.

Full textAbstract:
The 1929 ‘Davos encounter’ between Martin Heidegger and Ernst Cassirer has long been viewed by intellectual historians as a paradigmatic event not only for its philosophical meaning but also for its apparently cultural-political ramifications. But such interpretations easily lend legitimacy to a broader and recently ascendant intellectual-historical trend that would reduce philosophy to an allegorical expression of ostensibly more ‘real’ or instrumentalist meanings. However, as this essay tries to show, the core of the dispute between Cassirer and Heidegger is irreducibly philosophical: the Davos debate brought into focus the emergent themes of the so-called “Kant-crisis” of the 1920s, and cast new light upon neo-Kantian doctrines as to the status of objectivity and the possibility for intersubjective consensus in both knowledge and ethics. The Davos encounter cannot be retroactively decided on political or cultural grounds, since it concerns just that unresolved tension between transcendentalism and hermeneutics that is itself constitutive of intellectual history as a discipline.

Full textAbstract:
The emergence of the German Jewish philosopher Ernst Cassirer (1874–1945) as the object of scholarly attention has been both surprising and rapid. In the decades since his early death while in exile in the United States, Cassirer never fell into complete oblivion. His works remained known to specialists in German intellectual history; his participation in a famous 1929 debate with Martin Heidegger in Davos, Switzerland, one of the most iconic moments in modern Continental thought, made his name familiar to most students of modern philosophy. Yet Cassirer lacked the widespread recognition given to contemporaries such as Heidegger or Walter Benjamin, and his work never became the center of historical or philosophical study. This neglect stemmed, in part, from dismissal by his peers; as Edward Skidelsky explains in his new study, Rudolf Carnap found him “rather pastoral,” Isaiah Berlin dismissed him as “serenely innocent,” and Theodor Adorno thought he was “totally gaga” (125). The last few years, however, have seen the rise of a remarkable new interest in Cassirer in both Germany and the English-speaking world. Among this recent literature, Edward Skidelsky's and Peter Gordon's works lead the small “Cassirer renaissance” and offer the best English-language introduction to his thought. Both Gordon and Skidelsky ambitiously seek to relocate Cassirer at the forefront of modern German and European thought. Gordon goes as far as to call him “one of the greatest philosophers and intellectual historians to emerge from the cultural ferment of modern Germany” and one of the most important thinkers of the twentieth century (11). In making such bold statements, Gordon and Skidelsky clearly set their sights beyond the person himself; they aspire to highlight a central strand of thought that enjoyed a powerful presence in early twentieth-century Germany but fell into neglect in the postwar era. In doing so, they seek to reevaluate the nature and legacy of Weimar thought, its complex relationship with the period's unstable politics, and its relevance today.

Com ele queremos apenas destacar alguns pontos, segundo nós importantes, referentes à discussão da qual participaram vários filósofos do século XX a respeito do problema da metafísica na filosofia kantiana. Deve-se tomar Kant como o responsável pela destruição da metafísica? Ou, ao contrário, ele deve ser considerado um pensador metafísico por excelência? Na intenção de encontrar clareza para o enfrentamento dessas questões, o diálogo com autores como Henri Bergson, Ernst Wundt, Martin Heidegger e Ernst Cassirer é algo inevitável para quem tem interesse pela temática.

AbstractFour compositions for cello and string quartet on tape by American intermedia artist Phill Niblock originating from 1974 to 2003 are discussed. The interdependence of compositional approach and available technology is considered, leading to the observation that the electronic music composer's technique is considerably independent of the available technology. Where a dependence of artistic development on factors not originally musical has to be acknowledged, these nonmusical factors lie not so much in the technology but in Niblock's interpretation of it. This is discussed within the context of philosophical observations on art and technology by Theodor W. Adorno, Martin Heidegger and Ernst Cassirer.

Full textAbstract:
This article argues that Karl Löwith’s thesis of secularization—in brief, that while modern philosophical notions present themselves as secular, they are in fact secularized, that is, they preserve features of the theological background they repress and remain determined by it—can serve as a productive hermeneutical key for framing and understanding an important strand in the twentieth century Jewish response to Heidegger’s philosophy. It takes Ernst Cassirer, Leo Strauss, and Martin Buber as test-cases and demonstrates that these three Jewish thinkers interpreted various categories of Heidegger’s Being and Time to be not simply secular but secularized Christian categories that continue to bear the mark of their theological origin even in their now-secular application and context. The article concludes with a number of reflections and observations on how Löwith’s thesis of secularization can shed light on the polemical and political-theological edge of this strand in Heidegger’s Jewish reception.

Did Leibniz invent or, if you prefer, discover topology with his analysis situs? Yes, urge Nicholas Rescher (1978, p. 70), George MacDonald Ross (1984, p. 29) and Ian Hacking (1984, p. 213). No, urge Hans Freudenthal (1954/1972), Benson Mates (1986, p. 240) and Michael Otte (1989, p. 24). James Alexander (1932/1967, p. 249), drawing a distinction between point set and combinatorial methods, cautiously remarked that combinatorial topology “is more nearly a development of Leibniz's original idea.” Less cautiously, Morris Kline (1972, p. 1163) remarked that “to the extent that he was at all clear, Leibniz envisioned what we now call combinatorial topology.” Louis Couturat (1961, p. 429), Rudolf Carnap (1922, p. 81) and Ernst Cassirer (1950, p. 49) proposed projective geometry as the realization of Leibniz's project. Dennis Martin (1983, p. 5) sees topology as a development from analysis situs. Javier Echeverria (1988, p. 218), reporting on his archival research, argues that Leibniz “successfully introduced very general geometrical notions that boil down to what is known today as topology.” And a good many others, for and against, might be cited.

Abstract Scholars who are members of a generation descending from a founder of a philosophical school might be titled as “children.” Those members are characterized as scholars who continue the doctrines of the founder into the future. In the history of ideas there are many examples for such scholarly lineages. Ernst Cassirer’s philosophy was less suitable for generating a successorship in the sense of a filiation: That became dramatically obvious at the famous debate between Martin Heidegger and himself in Davos. Heidegger seemed to be the philosopher of the future by developing a “new essentialism” which shall be expounded as the core-message of his doctrine; this is elaborated in the first chapter of this essay. Only in the post-war generations and long time after Cassirer’s death, eminent scholars working in different scientific disciplines and in different countries based their public research – more or less explicitly – on Cassirer’s philosophy of culture. The second section will discuss three famous examples: Nelson Goodman’s Semiology, Pierre Bourdieu’s Sociology of Symbolic Forms and lastly the Political Philosophy of Jürgen Habermas.

Until recently, the Nisutlin allochthonous assemblage, a part of the Yukon–Tanana composite terrane interpreted as trench mélange from a late Paleozoic – Mesozoic arc system, was the only tectonic assemblage known to include subducted material in the northern Cordillera. The discovery of eclogitic rocks in two parts of a klippe of the Anvil allochthonous assemblage, which comprises mafic ophiolitic rocks, above the Cassiar terrane west of the Tintina fault confirms other evidence that subducted oceanic crust was also returned to the surface. The eclogitic rocks have been largely retrograded by postsubduction metamorphism. Their existence is interpreted as additional evidence of the link between nappes above the Cassiar terrane and their inferred root, the Teslin suture zone. The Nisutlin and Anvil allochthonous assemblages can now be interpreted, not simply as crustally metamorphosed assemblages with minor, structurally interleaved high-pressure components, but as deeply metamorphosed and intensely strained slices of continental and oceanic crust switched from subducting slab to overriding plate and returned to the surface during collision of the arc with the North American margin.

Full textAbstract:
The ancient Laurentian margin rifted in the latest Neoproterozoic to early Cambrian but appears not to have developed as a simple passive margin through a long, post-rift, drift phase. Stratigraphic and conodont biostratigraphic information from four platform-to-basin transects across the margin has advanced our knowledge of the early Paleozoic evolution of the margin. In northeastern British Columbia, two northern transects span the Macdonald Platform to Kechika Trough and Ospika Embayment, and a third transect spans the parautochthonous Cassiar Terrane. In the southern Rocky Mountains, new conodont biostratigraphic data for the Ordovician succession of the Bow Platform is correlated to coeval basinal facies of the White River Trough. In total, from 26 stratigraphic sections, over 25 km of strata were measured and > 1200 conodont samples were collected that yielded over 100 000 conodont elements. Key zonal species were used for regional correlation of uppermost Cambrian to Middle Devonian strata along the Cordillera. The biostratigraphy temporally constrains at least two periods of renewed extension along the margin, in the latest Cambrian and late Early Ordovician. Alkalic volcanics associated with abrupt facies changes across the ancient shelf break, intervals of slope debris breccia deposits, and distal turbidite flows suggest the margin was characterized by intervals of volcanism, basin foundering, and platform flooding. Siliciclastics in the succession were sourced by a reactivation of tectonic highs, such as the Peace River Arch. Prominent hiatuses punctuate the succession, including unconformities of early Late Ordovician, sub-Llandovery, possibly Early to Middle Silurian and Early Devonian ages.

Full textAbstract:
AbstractPost-breakup magmatic rocks are recognized features of modern and ancient passive margin successions around the globe, but their timing and significance to non-plume-related rift evolution is generally uncertain. Along the Cordilleran margin of western North America, several competing rift models have been proposed to explain the origins of post-breakup igneous rocks that crop out from Yukon to Nevada. New zircon U-Pb age and whole-rock geochemical studies were conducted on the lower Paleozoic Kechika group, south-central Yukon, to test these rift models and constrain the timing, mantle source, and tectonic setting of post-breakup magmatism in the Canadian Cordillera. The Kechika group contains vent-proximal facies and sediment-sill complexes within the Cassiar platform, a linear paleogeographic high that developed outboard of continental shelf and trough basins. Chemical abrasion (CA-TIMS) U-Pb dates indicate that Kechika group mafic rocks were generated during the late Cambrian (488–483 Ma) and Early Ordovician (473 Ma). Whole-rock trace-element and Nd- and Hf-isotope results are consistent with the low-degree partial melting of an enriched lithospheric mantle source during margin-scale extension. Equivalent continental shelf and trough rocks along western North America are spatially associated with transfer-transform zones and faults that were episodically reactivated during Cordilleran rift evolution. Post-breakup rocks emplaced along the magma-poor North Atlantic margins, including those near the Orphan Knoll and Galicia Bank continental ribbons, are proposed modern analogues for the Kechika group. This scenario calls for the release of in-plane tensile stresses and off-axis, post-breakup magmatism along the nascent plate boundary prior to the onset of seafloor spreading.

The allochthons are gently dipping thrust panels, interrupted by the mid-Cretaceous Cassiar Batholith. A key element for correlation across the batholith is the Mississippian and older pericratonic Dorsey Complex. New DevonianMississippian UPb ages for deformed plutons within it document an igneous suite like those in type YukonTanana exposures farther north. Other characteristics of the Dorsey Complex that ally it with YTT are orthoquartzites and grits, and amphibolite bodies with transitional mid-ocean ridge basalt (MORB) to ocean-island basalt (OIB) petrochemical signatures. Unconformities, deformed clasts in the late Paleozoic sequences, and a shared mid-Permian intrusive suite show that later arcs onlapped the mid-Paleozoic and older YTT assemblage. The Early Jurassic intrusive suite cuts all major contacts and fabrics except the terrane-bounding fault between the Slide Mountain and combined YTTQuesnel terranes. It represents a northern continuation of a plutonic belt that extends the length of the Mesozoic Quesnel magmatic arc. These relationships carry important implications for Cordilleran terrane history and the tectonic evolution of the North American margin. At least some of the major terranes were not unrelated entities prior to their accretion to the continent, but a system of superimposed and interconnected arcs that developed over a protracted time interval, with complex and evolving paleogeographic configurations much like the modern western Pacific province.

Abstract The northern Canadian Cordillera (NCC) of northwestern Canada is segmented by several margin-parallel, right-lateral, strike-slip faults that accumulated several hundred kilometers of displacement between the Late Cretaceous and the Eocene. The depth extent of these faults, notably the Tintina fault (TF), has important implications for the tectonic assemblage and evolution of NCC lithospheric mantle, but geophysical models and geochemical data remain inconclusive. Using a recent three-dimensional P-wave seismic velocity model, we resolved a series of sharp (∼10 km) P-wave velocity contrasts (∼4%) at uppermost mantle depths beneath the surface trace of the TF. Seismic anisotropy data that represent upper-mantle fabrics revealed similar changes in the orientation and magnitude of anisotropy in the vicinity of the TF. These data suggest that the TF is a lithospheric-scale shear zone. After restoration of 430 km of right-lateral displacement along the TF, fast P-wave anomalies align with the outline of the North American craton margin. We propose the fast anomaly structure currently located in eastern Alaska represents a fragment of the Mackenzie craton that was chiseled and displaced to the northwest by the TF between the Late Cretaceous and the Eocene. A second cratonic fragment currently located in the southern NCC may be associated with the Cassiar terrane at upper-mantle depth. These observations provide the first evidence that large lithospheric-scale shear zones cut through refractory mantle and produce major lateral displacement of cratonic mantle material within cordilleras worldwide.

ABSTRACT The Cordilleran Ice Sheet in Yukon radiated from ice-divides in the Selwyn, PeIIy1 Cassiar, and eastern Coast Mountains and was contiguous with a piedmond glacier complex from the St. Elias Mountains. Expansion of glaciers in divide areas could have been underway by 29 ka BP but these did not merge to form the ice sheet until after 24 ka BP. The firn line fell to approximately 1500 m at the climax of McConnell Glaciation. Flow within the ice sheet was more analogous to a complex of merged valley glaciers than to that of extant ice sheets: topographic relief was typically equal to or exceeded ice thickness, and strongly influenced ice flow. Surface gradients on the ice sheet were fractions of a degree. Steeper ice-surface gradients occurred locally along the digitate ice margin. Retreat from the terminal moraine was initially gradual as indicated by recessional moraines within a few tens of kilometres of the terminal moraine. Small magnitude readvances occurred locally. The ice sheet eventually disappeared through regional stagnation and downwasting in response to a rise in the firn line to above the surface of the ice sheet. Regional déglaciation was complete prior to approximately 10 ka BP.

In central Yukon, the pericratonic YukonTanana terrane (YT) is juxtaposed with the Cassiar terrane (CT, parautochthonous North America) along the Tummel fault zone (TFZ), a 34 km wide, northwest-trending belt comprising imbricate fault slices of Slide Mountain terrane (SM, greenstone, chert, serpentinite) and synorogenic clastic rocks. Northeast of the TFZ, the CT comprises Paleozoic metapelitic rocks, marble, and amphibolite of continental margin affinity. To the southwest, the YT consists of a pre-Late Devonian metasedimentary complex overlain and intruded by Mississippian clastic, volcanic, and plutonic successions of continental arc affinity. In the TFZ, Middle to Late Permian ocean-floor basalt of the SM shows evidence of crustal contamination, suggesting deposition at the edge of a marginal ocean basin. Deformation features in the TFZ include early ductile fabrics overprinted by younger brittle structures. Triassic synorogenic clastic rocks in the TFZ, and at the base of a klippen above the YT, suggest that terrane imbrication began shortly after the Early Triassic. 40Ar/39Ar mica ages from the region suggest cooling of the YT, SM, and part of CT below 300 °C by Early Jurassic time. Pervasive brittle structures in the Ragged Lake klippe, which roots into the TFZ, indicate brittle thrusting of the SM over the CT in post-Triassic time. Early Cretaceous plutons intrude the CT (Glenlyon Batholith) and the TFZ (leucogabbro) and impose a contact aureole that extends westward into the YT. Steep brittle structures that deformed the TFZ also affect, in part, the Glenlyon Batholith but do not significantly offset its contact aureole. Consequently, little displacement can have occurred along the TFZ after Early Cretaceous time.

Full textAbstract:
The Erickson gold mine is a typical gold quartz vein deposit. The veins are hosted by a thrust-imbricated, gently dipping, synformal allochthon of low-grade metamorphic, Devonian to Upper Triassic basalts, argillites, and peridotites of oceancrustal origin belonging to the Sylvester Group, part of the Slide Mountain assemblage. The Sylvester allochthon lies concordantly on Devonian miogeoclinal sedimentary rocks of the North American continental margin and was emplaced in the Middle Jurassic as a result of the collision of the Quesnel arc with North America. The veins in the mine are hosted mainly by a moderately dipping system of shear zones with approximately orthorhombic symmetry, indicating a triaxial bulk, inhomogeneous strain pattern superimposed on the earlier formed, gently dipping thrusts. Steeply dipping extension veinlets, rotation of schistosity, and downdip slickenlines indicate the maximum shortening axis was subvertical. The veins display complex superimposed ribbon and breccia textures, indicating incremental growth. Most of the gold occurs in association with tetrahedrite, sphalerite, and chalcopyrite in steeply dipping, late, grey quartz veinlets localized within and striking perpendicular to the main veins. The vein-forming event, dated at 130 Ma, appears to have been related to extension and high heat flow associated with the rise of the Omenica geanticline, in turn the result of crustal thickening caused by the collision of the amalgamated Quesnel arc – North America plate with Stikinia in the Middle Jurassic.

This study presents a broad geochemical and isotopic synthesis of mid-Cretaceous granites in the southern Yukon as well as a comparative data set for granites sourced from, and hosted by, accreted terranes in the west through to ancient cratonic rocks in the east. We present data from a traverse perpendicular to the strike of the northern Canadian Cordillera allowing comparison with the growing body of such data derived from the host terranes. Trace elements, specifically the “subduction signature,” allow the discrimination of oceanic verses continental crustal sources. Comparison of isotopic ratios of Sr and, particularly, Nd with published data further refine the correlation of granites with their source terranes. Granites are initially divided based upon their host morphogeological belts, however, our study indicates that the source terranes transcend these traditional boundaries. For Intermontane Belt hosted granites three distinct sources can be identified: an isotopically primitive (Sri, 0.7050; ϵNdT, 2.3 to –1.2), subduction-related source probably associated with the mid-Cretaceous continental margin; an isotopically primitive (Sri, 0.7032 to 0.7035; ϵNdT, 4.2 to 1.4), non-subduction-related source identified as the host Cache Creek terrane; and an isotopically slightly more evolved (Sri, 0.7094 to 0.7101; ϵNdT, 4.5 to –7.3), subduction-related source identified as the host Stikine terrane. Immediately east of the Teslin Tectonic Zone (TTZ), pericratonic Omineca granites (Sri, 0.7032 to 0.7076; ϵNdT, 2.0 to –5.4) do not correlate with their host terranes, but instead show marked similarities with granites immediately to the west of the TTZ suggesting that the same, or similar crustal sources extend further east in the subsurface than previously thought. In the eastern pericratonic Omineca Belt, there is a substantial jump to more evolved isotopic values (Sri, 0.7172 to 0.7354; ϵNdT, –16.6 to –21.7) for granites that extend to the most easterly exposed plutons of the cratonic Omineca Belt. These more isotopically evolved granites correlate with isotopic values for the pericratonic Yukon–Tanana and Cassiar terranes, as well as cratonic North America.

Full textAbstract:
In north-central British Columbia, a belt of upper Paleozoic volcanic and sedimentary rocks lies between Mesozoic arc rocks of Quesnellia and Ancestral North America. These rocks belong to two distinct terranes: the Nina Creek Group of the Slide Mountain terrane and the Lay Range Assemblage of the Quesnel terrane. The Nina Creek Group is composed of Mississippian to Late Permian argillite, chert, and mid-ocean-ridge tholeiitic basalt, formed in an ocean-floor setting. The sedimentary and volcanic rocks, the Mount Howell and Pillow Ridge successions, respectively, form discrete, generally coeval sequences interpreted as facies equivalents that have been interleaved by thrusting. The entire assemblage has been faulted against the Cassiar terrane of the North American miogeocline. West of the Nina Creek Group is the Lay Range Assemblage, correlated with the Harper Ranch subterrane of Quesnellia. It includes a lower division of Mississippian to Early Pennsylvanian sedimentary and volcanic rocks, some with continental affinity, and an upper division of Permian island-arc, basaltic tuffs and lavas containing detrital quartz and zircons of Proterozoic age. Tuffaceous horizons in the Nina Creek Group imply stratigraphic links to a volcanic-arc terrane, which is inferred to be the Lay Range Assemblage. Similarly, gritty horizons in the lower part of the Nina Creek Group suggest links to the paleocontinental margin to the east. It is assumed that the Lay Range Assemblage accumulated on a piece of continental crust that rifted away from ancestral North America in the Late Devonian to Early Mississippian by the westward migration of a west-facing arc. The back-arc extension produced the Slide Mountain marginal basin in which the Nina Creek Group was deposited. Arc volcanism in the Lay Range Assemblage and other members of the Harper Ranch subterrane was episodic rather than continuous, as was ocean-floor volcanism in the marginal basin. The basin probably grew to a width of hundreds rather than thousands of kilometres.

Full textAbstract:
Renaissance scholars such as Jacob Burkhardt, Ernst Cassirer, Paul Oskar Kristeller, and José Antonio Maravall have amply demonstrated that a program of letters (studia humanitatis) led, in the Renaissance, to a meditation on humanity. This article looks at the import of Renaissance letters in the more prosaic sense of alphabetic letters.
The printing press is of course the most obvious emblem of a new approach to alphabetic letters, and it is doubly important because it underscores the deep bonds between the philological program that reformed the study of Classical letters and a new means of textual transmission. This last has been the object of much good work by Elizabeth Eisenstein, Henri-Jean Martin, and Roger Chartier, among others. My concern here is more narrow.
I pose the question of how European attitudes toward the alphabetic letter related to the Renaissance meditation on humanity in the 15th and 16th centuries and I speculate on the implications the European conceptualization of the letter had for the confrontation with, and assimilation of, New World culture, particularly as it was found in Mexico. In this article, I move to a consideration of what resulted when the Spanish encountered a textuality -- the textuality of Meso-America -- that was not based on the letter.
Renaissance reformations of letter types reacted against the animated (to borrow Laura Kendricks' term) and corporeal medieval letter that stretched human and animal forms into letters (Giovanno de Grassi's alphabet is a representative instance). Against the monstrous medieval manuscript letter was pitted the Roman letter that, as 16th-century treatises proposed, deserved to become a model of rational order and symmetry. Fra Luca Pacioli (1497-1509) and Sigismondo de' Fanti (1514), for example, promulgated treatises on letter types, though Geoffroy Tory's great theoretical work Champ fleury (1529) stands out as the most sustained attempt to harmonize letter forms with the idealized human body as well as with Classical culture. For Tory, all letters are based on the form of the human body, as he demonstrates one by one from A to Z, using -- in typical Renaissance fashion -- a perfect, nude male form as his model. All of the letters are also simultaneously mapped onto a 10x10 grid, giving them a mathematical perfection. And all letters are combinations of the perfectly symmetrical "I" and "O", the "I" containing (for reasons Tory explains) the nine muses and Apollo while the "O" houses the seven liberal arts.
Tory's treatise therefore makes Roman letter types a key link between dignitas hominis and the program of studia humanitatis. In a similar manner, Thomas More, when he meditates on a utopian society, conceives it as having a more perfect set of alphabetic letters than European ones, the letters being set out at the beginning of the first two editions of his Utopia (1516) along with an example of Utopian literature written in the script. More's alphabet is even more perfectly ordered than Tory's Roman alphabet, as all of More's utopenses litterae are formed from the perfect geometrical forms of the circle and the square. A superior humanity corresponds to a superior alphabet (the equation can also be run in reverse).
What, then, are the implications of the European encounter with the New World, and, in particular, with the non-alphabetic culture of Meso-America? Meso-America, after all, was neither a culture without writing - a kind of "blank slate" Europeans could overwrite with letters - nor a lettered culture. Rather, it had a highly-developed pictogrammic system of writing that allowed it to produce texts that recorded, at one and the same time, historical accounts, tribute accounts, legends and calendars. The answer, to which I work, is that, for the Europeans, the textuality of the Meso-American empire needed to be brought under the reins of lettered European textuality just as their political territory needed to be conquered. The result was the creation of the mestizo codices that reproduced many elements of Pre-Columbian pictographic texts but organized them according to the exigencies of the European paginated book. In examining this phenomenon I argue that what was radically "other" was reduced to, and imported into Europe as, the radically "new," and I examine the relationship between alphabetic/non-alphabetic textualities and the European debate regarding the humanity of the Amerindians.
