The state of history and the empire of metaphysics [Review]

One of the curious things about this challenging book is that its ostensible subject— the Saxon medical and political scientist Hermann Conring (1606–1681)— is not mentioned in the title. Constantin Fasolt argues that we cannot know what Conring really thought or meant in his writings, which means that his topic cannot be Conring as such and must instead be that which occludes our knowledge of him, the titular limits of history. Given that we do in fact learn a good deal about Conring from Fasolt’s book, we can only hope that the decapitation of its subject will be rectified in a subsequent edition, or perhaps by the restorative work of librarians putting together subject headings. And yet Fasolt’s decision is understandable, for Conring is indeed a stalking-horse for a much bigger quarry: historiography and the historical consciousness. By “history” Fasolt understands a way of imposing intelligibility on the world, which is founded on the twin assumptions that the past is gone and unchangeable, and that the meaning of texts can be determined by placing them in their historical contexts (ix). In challenging this mode of intelligibility, Fasolt is not attempting to improve professiona history—it’s already as good as it can be—but to displace it. He regards his work as a declaration of “independence from historical consciousness” (32). At the same time, Fasolt insists that he is not simply jumping from historiography to philosophy, or attempting to preempt history with ontology (37-39). That has been tried by Nietzsche and Heidegger, who have been tainted by Nazism (Fasolt thinks unfairly). It has also been attempted by modern philosophers from Gadamer to Foucault and Charles Taylor who, in failing to address the “violence” that its mode of intelligibility does to the world, have not succeeded in outflanking history. Perhaps, Fasolt wonders, it is only the personal experience of those who have been subject to this violence—the experience of those who have been subject to historical examination—that can break the spell of history. Fasolt’s disclaimer notwithstanding, in the course of these remarks I shall argue that he is indeed jumping from history to philosophy, or attempting to outflank history by subjecting it to a particular metaphysical understanding. I shall do so in part by sketching the recent intellectual history of this move—a historical examination that I hope inflicts as little violence as possible on Fasolt’s argument.

Evolutionary theory of history

Several attempts have been made recently to apply Darwinian evolutionary theory to the study of culture change and social history. The essential elements in such a theory are that variations occur in population, and that a process of selective retention operates during their replication and transmission. Location of such variable units in the semantic structure of cognition provides the individual psychological basis for an evolutionary theory of history. Selection operates on both the level of cognition and on its phenotypic expression in action in relation to individual preferred sources of psychological satisfaction. Social power comprises the principal selective forces within the unintended consequences of action and through the struggle of individuals and groups in pursuit of opposing interests. The implication for historiography are methodological in that evolutionary theory of history sharpens the focus of explanatory situational analysis, and interpretive in that it provides a paradigmatic metanarrative for the understanding of historical change.

Direct writing of fibre Bragg gratings by femtosecond laser

A method for inscribing fiber bragg gratings (FBG) using direct, point-by-point writing by an infrared femtosecond laser was described. The method requires neither phase-masks nor photosensitized fibers and hence offers remarkable technology flexibility. It requires a very short inscription time of less than 60 s per grating. Gratings of first to third order were produced in non-photosensitized, standard telecommunication fiber (SMF) and dispersion shifted fiber (DSF). The gratings produced in this method showed low insertion loss, narrow linewidth and strong, fundamental or high-order resonance.

Femtosecond laser writing of buried waveguides in erbium III-Doped oxyfluoride glasses and nano-glass-ceramics

Femtosecond-pulsed laser writing of waveguides, a few mm long, is demonstrated; waveguides were written orthogonally to the writing beam inside the bulk of ErIII-doped oxyfluoride glasses at a depth of 160 mum. The writing beam was 795 nm wavelength, 54 fs pulse duration and 11 MHz repetition rate. Tracks were written at pulse energies of 13.1 nJ to 26.1 nJ and sample translational velocity of 10 mmmiddot.s-1 to 28 mmmiddots-1. The influence of translational velocity and pulse energy on the cross-sectional shape and integrity of the written tracks is reported. Tracks tend to be narrower as the pulse energy is lowered or translational velocity decreased. Above 22.9 nJ, pulse energy, tracks tend to crack. The estimated refractive index profile of one track has a maximum increase of refractive index of 0.003 at the centre. These glasses normally form nano-glass-ceramics on heat treatment just above the glass transformation temperature (Tg). Here, a post-fs-writing heat-treatment just above Tg causes nano-ceramming of the glass sample and removes a light-guiding peripheral region of the fs-written tracks suggesting that this region may have been fs-modified by stress alone. Waveguiding at 651 nm and 973 nm wavelengths, and upconversion, are demonstrated in optimally written tracks.

Remembrance of things past:the lingering impact of history on contemporary Polish-Ukrainian relations

This article investigates the continuing influence of the past on contemporary politics in Poland and Ukraine by examining the impact of the vocal 'informed' segment of public opinion on mutual relations between the two countries. The section 'What history?' examines the question of exactly what understanding of history matters so much in Polish-Ukrainian relations. The following sections examine how history influences the present, what are the contours of public opinion on Polish-Ukrainian relations within each state, and what is the impact of shared history on the contemporary politics of Polish-Ukrainian relations. Finally, the article suggests a potentially generaliseable hypothesis for future research.
