Material Form

Starting from a passage in the treatise De universali reali by Jean de Maisonneuve (Johannes de Nova Domo), where Jean de Maisonneuve denounces John Buridan as a materialist, the article looks for textual evidence that would support or otherwise refute this claim in Buridan’s works on natural philosophy. In particular, the article analyzes Buridan’s discussion of universal knowledge in the final redactions of his commentaries on Aristotle’s Physica and De anima, which turn out to complement each other. Here, Buridan asks if something extended and material can have universal knowledge. Against the opinion commonly held, according to Buridan, not only by many of his contemporaries, but also by almost all of the ancient commentators (multi et quasi omnes expositores antiqui), Buridan argues that traditional arguments against a materialistic theory of the human mind are not conclusive. After having removed the main stumbling blocks, he goes on to sketch a theory of universal knowledge that is compatible with the assumption that the human intellect is a material form. As an appendix, the paper contains an edition of the key question on universal knowledge in the penultimate redaction of John Buridan’s Physics commentary, which is made available in print for the first time here.

Aristotelian Metaphysics

In De Anima Book III, Aristotle subscribed to a theory of formal identity between the human mind and the extra-mental objects of our understanding. This has been one of the most controversial features of Aristotelian metaphysics of the mind. I offer here a defense of the Formal Identity Thesis, based on specifically epistemological arguments about our knowledge of necessary or essential truths.

Aqueous Two Phase Extraction

AbstractSolanum plants (Solanaceae) are renowned source of nutraceuticals and have widely been explored for their phytochemical constituents. This work investigated the effects of kosmotropic and chaotropic salts on the number of phytochemicals extracted from the leaves of a nutraceutical plant, Solanum retroflexum, and analyzed on the ultra-performance liquid chromatography hyphenated to a quadrupole time of flight mass spectrometer (UPLC-QTOF-MS) detector. Here, a total of 20 different compounds were putatively characterized. The majority of the identified compounds were polyphenols and glycoalkaloids. Another compound, caffeoyl malate was identified for the first time in this plant. Glycoalkaloids such as solanelagnin, solamargine, solasonine, β-solanine (I) and β-solanine (II) were found to be extracted by almost all the salts used herein. Kosmotrope salts, overall, were more efficient in extracting polar compounds with 4 more polyphenolic compounds extracted compared to the chaotropes. Chaotropes were generally more selective for the extraction of less polar compounds (glycoalkaloids) with 3 more extracted than the kosmotropes. The chaotrope and the kosmotrope that extracted the most metabolites were NaCl and Na2SO4, respectively, with 12 metabolites extracted for each salt. This work demonstrated that a comprehensive metabolome of S. retroflexum, more than what was previously reported on the same plant, can be achieved by application of kosmotropes and chaotropes as extractants with the aid of the Aqueous Two Phase Extraction approach. The best-performing salts, Na2SO4 or NaCl, could potentially be applied on a commercial scale, to meet the ever-growing demand of the studied metabolites. The Aqueous Two Phase Extraction technique was found to be efficient in simultaneous extraction of multiple metabolites which can be applied in metabolomics.

The nutrient metabolism, growth and development of plants are strongly affected by its nutrient plunder, and plants have different adaptive mechanisms to low-nutrient environments. The electrophysiological activities involve almost all life processes of plants. In this study, the active transport flow of nutrient (NAF) and nutrient plunder capacity (NPC) of plants were defined based on leaf intrinsic impedance (IZ), capacitive reactance (IXc), inductive reactance (IXL) and capacitance (IC) to evaluate the nutrient plunder capacity of plants for the first time. The results indicate that Orychophragmus violaceus had higher (p < 0.01) NPC and IC and lower (p < 0.01) IR, IXc, IXL and IZ as compared to Brassica napus L., which supports a superior ion affinity and that it could be better adapted to low-nutrient environments. UAF and NPC of plants exhibited good correlations with crude protein, crude ash and water content, and precisely revealed the plunder capacity and adaptive strategies of plants to nutrients. The present work highlights that O. violaceus had superior NPC and ion affinity compared with B. napus, and provided a novel, rapid, reliable method based on the plant’s electrophysiological information for real-time determination of the nutrient plunder capacity of plants.

In this study, we present descriptions, illustrations, comments, and bathymetric and geographic distributions of the brittle star species related to the estuary region of Camamu Bay, located in the State of Bahia, Brazil. The brittle star fauna lives on biological substrates, sand bottoms, mud and rubble in the Camamu Bay and comprises 12 species divided into five families. Almost all of them are common in the tropical and subtropical fauna of the regions of shallow water.Ophiophragmus filograneusis reported for the first time in Bahia, and nine other species are recorded for the first time in Camamu Bay:Amphipholis januarii, Amphipholis squamata, Ophiophragmus filograneus, Ophiostigma isocanthum,Ophioderma cinerea, Ophioderma januarii, Ophiactis lymani, Ophiactis savignyi andOphiocoma echinata.The results suggest that the ophiuroid assemblages are strongly affected by marine currents as well as by different kinds of bottom substrate.

The Relationship

Talking about God can not be separated from the activity of human thought. Activity is the heart of metaphysics. Searching religious authenticity tends to lead to a leap in harsh encounter with other religions. This interfaith encounter harsh posed a dilemma. Why? Because on the one hand religion is the peacemaker, but on the other hand it’s has of encouraging conflict and even violence. Understanding God is not quite done only by understanding the religion dogma, but to understand God rationally it is needed. It is true that humans understand the world according to his own ego, but it is not simultaneously affirm that God is only a projection of the human mind. Humans understand things outside of himself because no awareness of it. On this side of metaphysics finds itself. Analogical approach allows humans to approach and express God metaphysically. Human clearly can not express the reality of the divine in human language, but with the human intellect is able to reflect something about the relationship with God. Analogy allows humans to enter the metaphysical discussion about God. People who are at this point should come to the understanding that God is the Same One More From My mind, The Impossible is defined, the Supreme Mystery, and infinitely far above any human thoughts.

The blister beetle (Coleoptera: Meloidae) fauna of Namibia is studied. The species are arranged within a catalogue containing information on their general distribution, including a list of localities and brief taxonomic remarks. Zoogeographic and ecological analyses were carried out and a photographic appendix, with images and maps of almost all Namibian species, is included. According to a chorological analysis, the Namibian blister beetle fauna appears to be zoogeographically distinct because of the dominance of western southern African elements. The faunistic levels of similarity among distinct areas in Namibia are also analysed. Several of the endemic species are related to the xeric ecosystems referable to the Namib Desert, Succulent Karoo and Nama Karoo biomes, but the highest diversity is related to the ecosystems referable to the Savannah biome. A total of 148 species belonging to 28 genera, eight tribes and three subfamilies (Eleticinae,  Meloinae, Nemognathinae) are recorded from this southern African country. Five new genera (Namibeletica gen. nov., Eleticinae Eleticini; Dilatilydus gen. nov. and Desertilydus gen. nov., Meloinae Lyttini; Paramimesthes gen. nov. and Namylabris gen. nov, Meloinae Mylabrini) and a total of 13 new species are described: 11 new species from Namibia (Psalydolytta gessi sp.nov., Paramimesthes namibicus sp.nov., Namylabris adamantifera sp.nov., Hycleus arlecchinus sp.nov., H. planitiei sp.nov., H. dvoraki sp.nov., H. aridus sp.nov., H. san sp.nov., Nemognatha fluviatilis sp.nov., “Zonitoschema” deserticola sp.nov., Zonitoschema dunalis sp.nov.); a new Namibeletica from the Angolan Namib (N. angolana) and a new Afrolytta Kaszab, 1959 from the S African Namaqualand (A. namaqua), both close to Namibian borders. Fourty-eight species and the genus Apalus Fabricius, 1775 are recorded for the first time from Namibia, and a few other species from South Africa (1), Zambia (1), Botswana (1) and Congo (1). The following new synonymies are proposed: Lytta pleuralis var. inpleuralis Pic, 1911 = Lydomorphus (Lydomorphus) thoracicus (Erichson, 1843), syn. nov.; Lytta benguellana Pic, 1911 = Prionotolytta melanura (Erichson, 1843), syn. nov.; Actenodia amoena ssp.anthicoides Kaszab, 1955b = Hycleus amoenus (Marseul, 1872), syn. nov.; Decapotoma csikii Kaszab, 1953 = Hycleus benguellanus (Marseul, 1879), syn. nov.; Nemognatha capensis Péringuey, 1909 = Nemognatha peringueyi Fairmaire, 1883, syn. nov. Several new combinations in the genus Hycleus Latreille, 1817 are also established.

The Way

Why is the human mind able to perceive and understand the truth about reality; that is, why does it seem to be the mind's specific function to know the world? Sean Kelsey argues that both the question itself and the way Aristotle answers it are key to understanding his work De Anima, a systematic philosophical account of the soul and its powers. In this original reading of a familiar but highly compressed text, Kelsey shows how this question underpins Aristotle's inquiry into the nature of soul, sensibility, and intelligence. He argues that, for Aristotle, the reason why it is in human nature to know beings is that 'the soul in a way is all beings'. This new perspective on the De Anima throws fresh and interesting light on familiar Aristotelian doctrines: for example, that sensibility is a kind of ratio (logos), or that the intellect is simple, separate, and unmixed.

Object Of Study

Conrad Gessner (1516–65) was town physician and lecturer at the Zwinglian reformed lectorium in Zurich. His approach towards the world and mankind was centred on his preoccupation with the human soul, an object of study that had challenged classical writers such as Aristotle and Galen, and which remained as important in post-Reformation debate. Writing commentaries on Aristotles De Anima (On the Soul) was part of early-modern natural philosophy education at university and formed the preparatory step for studying medicine. This article uses the case study of Gessners commentary on De Anima (1563) to explore how Gessners readers prioritised De Animas information. Gessners intention was to provide the students of philosophy and medicine with the most current and comprehensive thinking. His readers responses raise questions about evolving discussions in natural philosophy and medicine that concerned the foundations of preventive healthcare on the one hand, and of anatomically specified pathological medicine on the other, and Gessners part in helping these develop.
