Ernst Haeckel e il “rompicapo” dello sviluppo embrionale tra arte e scienza
2018
Every biological form can be explained as the product of two different processes: the development from the egg (also known as “ontogenesis”) and the evolution from the ancestors (the “phylogenesis”). Charles Darwin, the father of evolutionism, recognized the importance of both processes to explain the variety of living creatures and their relationship, but only a few of his followers were aware of this theoretical connection. In this article we will try to understand how the evolutionist scientist Ernst Haeckel elaborate his embryological theories and, in particular, the well-known “theory of recapitulation”, also known as “biogenetic law”. Furthermore, we will try to discover the value of …
Ernst Haeckel tra Estetica e Morfologia. Un pensiero che prende forma
2020
Negli ultimi decenni del Novecento, grazie all’affermarsi delle tematiche ecologiche e al maggior peso esercitato dalle questioni biologiche sui domini d’indagine della filosofia, si è riscoperta la solidità concettuale del vincolo fra forma e vita, in una contaminazione di saperi che ha dato origine a percorsi di grande interesse fra le due discipline. Essa ha favorito, in particolare, la riscoperta di prospettive teoriche – come la Morfologia – a lungo trascurate dal dibattito scientifico, poiché interessate a indagare solo l’“apparire” del vivente e il suo manifestarsi alla nostra sensibilità. Nell’ambito di tale riscoperta un ruolo importante è svolto da Ernst Haeckel, discepolo di Darw…
Il corpo come strumento della sensibilità: riflessioni sul conoscere e il sentire fra estetica e fisiologia
2016
Since its origins, the controversial relationship between sensible knowledge and conceptual knowledge is a central problem of aesthetics. The reflections of A.G. Baumgarten, the “father of modern aesthetics”, played a key role for the revaluation of senses and corporeity, although, in his works, the constructability of aesthetics is not extended to physiological topics yet. In this article we aim to understand the role played by senses and body structure in all living beings, from unicellular organisms to human beings; at the same time, we try to understand the importance of senses for environmental comprehension, adopting a morphological perspective and keeping together philosophical and s…
Human amniotic stem cells improve hepatic microvascular dysfunction and portal hypertension in cirrhotic rats
2020
BACKGROUND AND AIMS Portal hypertension is the main consequence of cirrhosis, responsible for the complications defining clinical decompensation. The only cure for decompensated cirrhosis is liver transplantation, but it is a limited resource and opens the possibility of regenerative therapy. We investigated the potential of primary human amniotic membrane-derived mesenchymal stromal (hAMSCs) and epithelial (hAECs) stem cells for the treatment of portal hypertension and decompensated cirrhosis. METHODS In vitro: Primary liver sinusoidal endothelial cells (LSECs) and hepatic stellate cells (HSCs) from cirrhotic rats (chronic CCl4 inhalation) were co-cultured with hAMSCs, hAECs or vehicle for…

Il disegno come immagine adeguata del reale. Ernst Haeckel, l’illustrazione scientifica e la controversia sulla riproduzione fotografica del vivente
2020
The works of Ernst Haeckel, one of the staunchest defenders of Darwin and amateur artist, brought Goethian morphology to new horizons, contributing to the affirmation of evolutionism. Overcoming the traditional disciplinary boundaries, he promoted a “biological Aesthetics”, convinced that the artistic representation of living forms is more profound and stimulating for science than any photographic reproduction. In fact, in his opinion, the scientist is a free interpreter of vital phenomena and his drawings are able of grasping the essence of biological processes. Reading some Haeckelian works, in this article we will try to clarify why the photographer has a passive view of the world, repro…
Plantinga’s Haecceitism and Simple Quantified Modal Logic
2017
In a series of papers Alvin Plantinga argued for a serious actualist modal semantics based on the notions of possible world, understood as maximal possible state of affairs, and of individual essence (haecceity). Plantinga’s actualism is known as haecceitism. In spite of the fact that haecceitism has been thought by Plantinga to require a Kripke-style semantics, the aim of this paper is to show that it is compatible with constant domains semantics and the simplest quantified modal logic. I will argue that not only does this approach have all the advantages of a greater simplicity in combining quantification and modalities, but also it better conforms to the actualist program.
