Luigi Stefanini e Giuseppe Zamboni. La “persona umana” tra pensiero ed essere
No full textCon questo contributo ho cercato di evidenziare come vi siano molteplici e interessanti punti di convergenza tra il personalismo di Luigi Stefanini e quello di Giuseppe Zamboni (oggetto, quest’ultimo della mia sopraccitata monografia: D. POGGI, La coscienza e il meccanesimo interiore). Mi sono concentrato sul rapporto tra psicologia e ontologia, sul riconoscimento dell’importanza di un approccio “integrale” all’esperienza e sul nesso sussistente tra il concreto sum percepito dal soggetto e l’idea astratta e indeterminata di esse, per cui, in virtù della propria condizione intrinseca di autotrasparenza intellettiva, il soggetto è “energia autocosciente e autopercipiente” (Zamboni parla di intellectualis naturae individua substantia) o, riprendendo un’espressione di Stefanini, Ens declarativum et manifestativum sui
Roberto Poggi. Il rigore e la libertà del mestiere
No full textElectaarchitettura pubblica la prima monografia dedicata alla storia della ditta pavese Poggi, corredata dal regesto completo degli arredi realizzati. La vicenda professionale del produttore di mobili Roberto Poggi (1924) è al contempo esemplare e atipica. Con il fratello Ezio trasfonde i saperi artigianali del padre Carlo, fondatore dell’omonima falegnameria pavese, in una produzione di arredi innovativi in cui è possibile leggere sia l’eredità della tradizione manifatturiera lombarda, sia gli stimoli dalla cultura architettonica e artistica milanese del dopoguerra.
A partire dalla fine degli anni Quaranta, un trentennale sodalizio con Franco Albini testimonia la capacità di Poggi di condividere e affinare l’impostazione metodologica e la tensione espressiva dell’architetto, esaltandole in raffinati arredi di serie, destinati a diventare inconfondibili icone del design italiano.
La maniacale cura del dettaglio, dell’incastro, del materiale, della disposizione della venatura del legno rispetto agli sforzi strutturali più gravosi, accomuna i prodotti di Poggi dagli esordi per tutta la sua attività, ritrovandosi intatta negli arredi realizzati o solo progettati da Corrado Levi e Laura Petrazzini, Umberto Riva, Renzo Piano, Ugo La Pietra, Afra e Tobia Scarpa, Achille Castiglioni, Marco Zanuso, Vico Magistretti: soltanto alcuni dei numerosi architetti che a Pavia non trovarono solo un esecutore

Scutellum with length 1.59–1.68× width, posterior section with narrowly rounded apex. Prosternum with low median carina on anterior part, anterior margin straight. Mesosternum with a pair of low tubercles on anterolateral margin, posterior projection between middle coxae truncate, weakly grooved along midline.

Phallotheca moderately sclerotised, as in Fig. 25.</p> <p>Female: Unknown.</p> <p> <b>Etymology.</b> The new species is dedicated to Dr. Tan Heok Hui (Lee Kong Chian Natural History Museum), for his significant contribution to the water bug collection in the LKCNHM, including numerous samples of <i>Ranatra</i>.</p> <p> <b>Discussion.</b> <i>Ranatra heoki</i> <b>sp.n.</b> also belongs to the <i>R. gracilis</i> species group (<i>sensu</i> Lansbury, 1972). It can be easily distinguished from other taxa of this species group by the following characteristics: (a) the height of the tubercle on the vertex is about a half the height of an eye in lateral view; (b) the clypeus has a small, but distinct tubercle above the lora (Fig. 17); and (c) the paramere is dorsoventrally thick, with the dorsal surface almost straight, and strongly constricted at the distal quarter before a broadly curved apical hook, and its subapical process is sub-triangular, bearing long setae (Figs. 26, 27).</p> <p> Among taxa of the <i>R. gracilis</i> group, the general appearance of the paramere of this new species is most similar to that of <i>R. schuhi</i> from Myanmar. However, it can be easily distinguished from <i>R. schuhi</i> by the following characteristics: <i>Ranatra heoki</i> <b>sp.n.</b> has a shorter body, with length excluding siphon ca. 25 mm (in <i>R. schuhi</i>, body length is ca. 32 mm). The clypeus of the new species has a small tubercle above the lora (in <i>R. schuhi</i>, the clypeus above the lora is flat and without a tubercle). The ratio of length of the anterior pronotal lobe to length of the posterior protonal lobe is greater in <i>R. heoki</i> <b>sp.n.</b> (2.2–2.3: 1.0) than in <i>R. schuhi</i> (ca. 1.9: 1.0). In the new species, the pair of tubercles at the anterior margin of the mesosternum is less prominent than that in <i>R. schuhi</i>. The hemelytra of <i>R. heoki</i> <b>sp.n.</b> is uniformly textured, mostly brown and shorter, and the membrane reaches only midlength of abdominal tergum VI (hemelytra of <i>R. schuhi</i> is reddish brown with yellow maculated marks and longer, and the membrane reaches to the posterior margin of abdominal tergum VI). The fore femur of <i>R. heoki</i> <b>sp.n.</b> does not widen distally, the maximum width anterior to the median tooth is less than the maximum width posterior to the median tooth (in <i>R. schuhi</i>, the fore femur widens distally, with the maximum width anterior to the median tooth greater than the maximum width posterior to the median tooth). In <i>R. heoki</i> <b>sp.n.</b>, the median tooth of fore femur is more prominent, the width of the femur across the median tooth is slightly greater than the maximum width of the basal part of the femur (in <i>R. schuhi</i>, the width of the femur across the median tooth is subequal to the maximum width of the basal part of the femur). The hind femur of <i>R. heoki</i> <b>sp.n.</b> is shorter and does not reach the posterior margin of abdominal sternum VI when folded back parallel to abdomen (the hind femur of <i>R. schuhi</i> is longer, reaching the anterior half of the operculum). In <i>R. heoki</i> <b>sp.n.</b>, the respiratory siphon has only sparse setae along its ventral margin, without a fringe of dense erect setae (in <i>R. schuhi</i>, the respiratory siphon has a fringe of erect setae along the ventral margin in the basal half).</p> <p> The parameres of these two species have a similar general appearance, but they differ in the following details. The paramere of <i>R. heoki</i> <b>sp.n.</b> is dorsoventrally thicker; its dorsal surface is almost straight, not sinuate, and is constricted in the distal quarter; its distal hook is shorter, with a more open curve, directing its apex ventrad; and the subapical process is more acute, and sub-triangular. In contrast, the paramere of <i>R. schuhi</i> is sinuate in the basal part and is constricted in the distal third; its distal hook is longer and recurved, directing its apex anteroventrad; and the subapical process is round.</p> <p>Female specimen is not available for comparison.</p> <p> <b>Distribution.</b> Borneo: Sarawak.</p>Published as part of <i>Tran, A.

«Ce MOY qui dit beaucoup»: la persona umana e il reale nella gnoseologia zamboniana
No full textIl saggio analizza la concezione della persona umana e del reale nella gnoseologia di Giuseppe Zamboni, ponendola in dialogo critico con alcune delle principali alternative filosofiche della modernità, in particolare l’idealismo, il positivismo e la fenomenologia. Muovendo dalla crisi del soggetto come “problema” e “sfida” teorica, l’autore mostra come la gnoseologia pura elementare zamboniana consenta di superare tanto il soggettivismo quanto i riduzionismi naturalistici, restituendo piena dignità al reale nella sua resistenza e autonomia. Attraverso un’analisi puntuale dei concetti di presenza, manifestazione e coscienza, il contributo chiarisce il ruolo dell’io come polo conoscitivo non costitutivo, ma rivelativo del reale. Il confronto con Leibniz, sintetizzato nella formula «ce MOY, qui dit beaucoup», permette infine di mettere in luce la fecondità di un metodo gnoseologico capace di fondare un realismo critico, personalista e anti-idealista, in cui la persona umana emerge come dispositivo privilegiato di comprensione dell’esperienza integrale
