Hybrid philosophy and rational vitalism in Canguilhem and Ortega y Gasset

This paper explores the problem of the synthesis between vitalism and rationalism, in contemporary philosophy. With this aim, we compare the intellectual careers of Georges Canguilhem (1904-1995) and José Ortega y Gasset (1883-1955). We contrast their conceptions of philosophy as “hybrid” knowledge, closely related to science, as well as their points of view on Vitalism, anthropology, the technique and the perspectivism. To avoid that comparison is purely abstract and ahistorical, we use the method of the sociology of philosophy. This forces us to locate both paths in their respective philosophical fields and generational units, also according to his social background and professional career.

Resolution of a taxonomic conundrum: an ultrastructural and molecular description of the life cycle of Pleistophora mulleri (Pfeiffer 1895; Georgevitch 1929)

The classification of a microsporidian parasite observed in the abdominal muscles of amphipod hosts has been repeatedly revised but still remains inconclusive. This parasite has variable spore numbers within a sporophorous vesicle and has been assigned to the genera Glugea, Pleistophora, Stempellia, and Thelohania. We used electron microscopy and molecular evidence to resolve the previous taxonomic confusion and confirm its identification as Pleistophora mulleri. The life cycle of P. mulleri is described from the freshwater amphipod host Gammarus duebeni celticus. Infection appeared as white tubular masses within the abdominal muscle of the host. Light and transmission electron microscope examination revealed the presence of an active microsporidian infection that was diffuse within the muscle block with no evidence of xenoma formation. Paucinucleate merogonial plasmodia were surrounded by an amorphous coat immediately external to the plasmalemma. The amorphous coat developed into a merontogenetic sporophorous vesicle that was present throughout sporulation. Sporogony was polysporous resulting in uninucleate spores, with a bipartite polaroplast, an anisofilar polar filament and a large posterior vacuole. SSU rDNA analysis supported the ultrastructural evidence clearly placing this parasite within the genus Pleistophora. This paper indicates that Pleistophora species are not restricted to vertebrate hosts.

Irish social thought and the relief of poverty, 1847-1880

This paper investigates the way in which the ‘problem of poverty’ in Ireland was encountered, constructed and debated by members of the Irish intellectual and political elite in the decades between the Great Famine and the outbreak of the land war in the late 1870s. This period witnessed acute social upheavals in Ireland, from the catastrophic nadir of the Famine, through the much-vaunted economic recovery of the 1850s–1860s, to the near-famine panic of the late 1870s (itself prefigured by a lesser agricultural crisis in 1859–63). The paper focuses on how a particular elite group – the ‘Dublin School’ of political economists and their circle, and most prominently William Neilson Hancock and John Kells Ingram – sought to define and investigate the changing ‘problem’, shape public attitudes towards the legitimacy of welfare interventions and lobby state officials in the making of poor law policy in this period. It suggests that the crisis of 1859–63 played a disproportionate role in the reevaluation of Irish poor relief and in promoting a campaign for an ‘anglicisation’ of poor law measures and practice in Ireland.

Dos décadas de una atormentada relación: Martin Heidegger y Edmund Husserl 1909-1929

La publicación reciente de documentos y la consulta directa en archivos posibilita un acercamiento renovado a la conflictiva relación entre Edmund Husserl y Martin Heidegger. El artículo lleva a cabo esto mediante una revisión del camino académico de Heidegger a la sombra de su protector Husserl. De ese modo se dejan ver las escisiones anímicas del joven Heidegger, su apropiación de la fenomenología husserliana y a la vez su distanciamiento del maestro. Con ello también se muestra que el rompimiento entre ambos pensadores no tiene su origen en los compromisos políticos de Heidegger en 1933, sino que era algo que latía desde el inicio de la relación.
