Pothos suggests dispensing with the distinction between rules and similarity, without defining what is meant by either term. We agree that there are problems with the distinction between rules and similarity, but believe these will be solved only by exploring the representations and processes underlying cases purported to involve rules and similarity.
Because the status of nature is ambiguous in Being and Time, we explore an ecological perspective on Heidegger’s early main work in this article. Our hypothesis is that the affordance theory of James Gibson enables us to a) to understand being-in-the-world as being-in-nature, b) reconnect man and nature and c) understand the twofold sense of nature in Being and Time. After exploring Heidegger’s concept of being-in-the-world and Gibson’s concept of being-in-nature, we confront Heidegger’s and Gibson’s conception of being-in-the-world and being-in-nature. (...) It will become clear that Gibson’s affordance theory enables an ecological reading of Being and Time, in which the relational character of being-in-the-world is stressed and the exceptional position of human being-in-the-world has to be rejected. Moreover, it becomes clear that an ecological reading of Being and Time enables us to reconnect being-in-the world with being-in-nature, which is rooted in “primordial” nature as its infinite origin.

We introduce the bimodal logic , which is the extension of Bennett’s bimodal logic by Grzegorczyk’s axiom □→p)→p and show that the lattice of normal extensions of the intuitionistic modal logic WS5 is isomorphic to the lattice of normal extensions of , thus generalizing the Blok–Esakia theorem. We also introduce the intuitionistic modal logic WS5.C, which is the extension of WS5 by the axiom →, and the bimodal logic , which is the extension of Shehtman’s bimodal logic by Grzegorczyk’s (...) axiom, and show that the lattice of normal extensions of WS5.C is isomorphic to the lattice of normal extensions of.

It is well-known that da Costa's C-systems of paraconsistent logic do not admit a Blok-Pigozzi algebraization. Still, an algebraic flavored semantics for them has been proposed in the literature, namely using the class of so-called da Costa algebras. However, the precise connection between these semantic structures and the C-systems was never established at the light of the theory of algebraizable logics. In this paper we propose to study the C-systems from an algebraic point of view, and to fill in (...) this gap by using the tools and techniques of the newly developed behavioral approach to abstract algebraic logic. As a by-product of the approach, we also rediscover the bivaluation semantics of the logics. (shrink)
Multialgebras (or hyperalgebras) have been very much studied in the literature. In the realm of Logic, they were considered by Avron and his collaborators under the name of non-deterministic matrices (or Nmatrices) as a useful semantics tool for characterizing some logics (in particular, several logics of formal inconsistency or LFIs) which cannot be characterized by a single finite matrix. In particular, these LFIs are not algebraizable by any method, including Blok and Pigozzi general theory. Carnielli and Coniglio introduced a (...) semantics of swap structures for LFIs, which are Nmatrices defined over triples in a Boolean algebra, generalizing Avron's semantics. In this paper we develop the first steps towards the possibility of defining an algebraic theory of swap structures for LFIs, by adapting concepts of universal algebra to multialgebras in a suitable way.

Two famous negative results about da Costa’s paraconsistent logic ${\mathscr {C}}_1$ (the failure of the Lindenbaum–Tarski process [44] and its non-algebraizability [39]) have placed ${\mathscr {C}}_1$ seemingly as an exception to the scope of Abstract Algebraic Logic (AAL). In this paper we undertake a thorough AAL study of da Costa’s logic ${\mathscr {C}}_1$. On the one hand, we strengthen the negative results about ${\mathscr {C}}_1$ by proving that it does not admit any algebraic semantics whatsoever in the sense of (...) class='Hi'>Blok and Pigozzi (a weaker notion than algebraizability also introduced in the monograph [6]). On the other hand, ${\mathscr {C}}_1$ is a protoalgebraic logic satisfying a Deduction-Detachment Theorem (DDT). We then extend our AAL study to some paraconsistent axiomatic extensions of ${\mathscr {C}}_1$ covered in the literature. We prove that for extensions ${\mathcal {S}}$ such as ${\mathcal {C}ilo}$ [26], every algebra in ${\mathsf {Alg}}^*({\mathcal {S}})$ contains a Boolean subalgebra, and for extensions ${\mathcal {S}}$ such as,, or [16, 53], every subdirectly irreducible algebra in ${\mathsf {Alg}}^*({\mathcal {S}})$ has cardinality at most 3. We also characterize the quasivariety ${\mathsf {Alg}}^*({\mathcal {S}})$ and the intrinsic variety $\mathbb {V}({\mathcal {S}})$, with,, and. (shrink)
After Einstein presented his “special theory of relativity” with its marvelous principles, “principle of relativity” and “the constant speed of light”, it led to bizarre implications, such as, time dilation, length contraction, energy-mass conversion, and invariance of the space-time interval, we had trouble to understand these stunning consequences with our very classical ontology, which can be regarded as Aristotelian ontology. Thus, both physicists and philosophers have required a new kind of ontology, capable of explaining the new phenomena. Hermann Minkovski proposed (...) that Einstein’s theory implies a “four-dimensional space-time”, instead of a three-dimensional space with time passing over space. Accordingly, the universe consists of four-dimensional stuff such as events. Event ontology goes together with “block universe argument”. Accordingly, the universe looks like a block of ice or a loaf of bread and in which past, present and future take place together. Therefore, block universe argument makes impossible change, motion, and causal relations. Although they sound strange, “simultaneity of relativity”, an outcome of special theory of relativity, supports event ontology and block universe argument. Nevertheless, there are plenty of difficulties come along with the event ontology. In this paper, I will discuss those handicaps of the argument that events are basic components of the universe.Einstein, “özel görelilik kuramını” ve olağanüstü iki ilkesini, “görelilik ilkesini” ve “ışık hızının sabitliğini”, sunduktan sonra, bu kuramın Aristotelesci ontoloji olarak tabir edebileceğimiz klasik ontolojinin kavramlarıyla anlaşılması zor çıktıları oldu. Örneğin, zamanın genişlemesi, uzunluğun kısalması, enerji-kütle değişimi ve uzam-zaman aralığının değişmezliği gibi. Bu nedenle, hem fizikçiler hem de felsefeciler yeni keşfedilen olguları açıklayabilecek yeni bir ontolojinin gerekliliğini duydular. Hermann Minkovski proposed that Einstein’ın kuramının; zamanın, uzamın dışında olduğu üç-boyutlu uzam yerine “dört-boyutlu bir uzam-zaman” içerdiğini iddia etti. Buna göre evren, “olaylar” gibi dört-boyutlu şeylerden ibaret. Olay ontolojisi, “blok evren argümanı” ile uyuşur. Blok evren argümanına göre, evren bir buz kütlesine ya da bir somun ekmeğe benzer. Geçmiş, şimdi ve gelecek bu bloğun içinde aynı anda yer almaktadır. Bu nedenle blok evren argümanı; değişimi, hareketi ve nedensel ilişkileri imkansız kılar. Bu argüman tuhaf görünse de özel görelilik kuramının bir çıktısı olan “göreliliğin eş zamanlılığı”, olay ontolojisini ve blok evren argümanını destekler. Yanı sıra olay ontolojisi pek çok zorluğu da beraberinde getirir. Bu makalede, olayların evrenin temel yapı taşları olduğu iddiasınının zorluklarını tartışacağım. (shrink)
Frankfurt Okulu'nun kurucu üyelerinden ve 20. yüzyıl eleştirel düşünce dünyasının köşe taşlarından biri olan Herbert Marcuse'nin 1969 yılında, bütün dünyanın halk ayaklanmalarıyla ve toplumsal hareketlerle çalkalandığı sıcak günlerde yayımlanan kitabı Özgürlük Üzerine Bir Deneme ele aldığı konuları ve tespitleriyle günümüzde de önemini koruyor. Bu kısa ama çarpıcı makale, Sol'un teorik ve pratik yeniden inşası ve eleştirel düşüncenin doğru mecralarda ilerleyişinin sağlanması açısından mutlaka okunması ve derinlemesine irdelenip tartışılması gereken eserlerin başında gelir. İleri endüstri toplumuyla rekabete giren sosyalist blok, bu (...) rekabetin bir sonucu olarak, kendi hedeflerinden saparak rekabet ettiği sistemin değerlerinin egemen olduğu bir sisteme kaymıştır. Bu kayma, Marcuse'ye göre, geleneksel özgürlük anlayışını geçersiz kılmıştır. Artık, insanların gereksinimleri özgürce kendileri tarafından geliştirilmediği için, “herkesten yeteneğine göre, herkese gereksinimine göre” ilkesinin işe yaramayacağı bir aşamadayız. Öyle ki, kendilerinin özgürce geliştirdikleri gereksinimlere sahip olmadıkları sürece, üretim araçlarının işçiler tarafından sahiplenildiği durumda bile, toplum baskıcı bir toplum olabilir. Dolayısıyla, özgürlüğünün olanakları başka yerlerde aramak gerekir. Marcuse de, Özgürlük Üzerine Bir Deneme kitabında, bu yeni durum içerisinde özgürlüğün yeni olanaklarını aramaktadır. (shrink)
As a distinctive voice in the current philosophy of technology, postphenomenology elucidates various ways of how technologies “shape” both the world and humans in it. Distancing itself from more speculative approaches, postphenomenology advocates the so-called empirical turn in philosophy of technology: It focuses on diverse effects of particular technologies instead of speculating on the essence of technology and its general impact. Critics of postphenomenology argue that by turning to particularities and emphasizing that technologies are always open to different uses and (...) interpretations, postphenomenology becomes unable to realize how profoundly technology determines our being in the world. Seeking to evaluate the postphenomenological ability to radically reflect on the human being conditioned by technology, I discuss the two most pertinent criticisms of postphenomenology: an “existential” one by Robert C. Scharff and an “ontological” one by Jochem Zwier, Vincent Blok, and Pieter Lemmens. Assessing the ontological alternative, I point to incapacity of Heidegger’s concept of Enframing to do justice to material technologies. Simultaneously, I acknowledge the necessity of speculating on technology as transcending concrete technologies. Such speculating would be instrumental in reviving Ihde’s idea of non-neutrality of technology in its full philosophical potency. (shrink)
Organized for the third time, the elections for the European Parliament at direct universal suffrage, in June 1989, had the following main characteristics: a still weak turnout, a progress for the socialist parties in most countries, a rather distinct rise of the Environmentalists and an indisputable rise of some far-right parties.In Belgium, the results cannot be compared exclusively with those of the 1984 European election. They must be seen in the continuation of the 1985 and 1987 general elections.Then, the main (...) characteristics are as follows : a near disappearance of the farleft lists associated with the absence of communist lists, a very marked rise of the Environmentalists, stronger in the Walloon Region than in Flanders, a progress for the Christian lists, especially for the C.V.P. in the Flemish districts, a setback for the Flemisch Socialists and a progress for the French-speaking Socialists in comparison with the 1984 poll. This progress, however, was not important enough as to enable them to regain their 1987 level. The Liberals are experiencing a setback compared with 1987 in the three regions of the country and, as far as the P.R.L. is concerned, even in comparison with 1984 and 1985.The Volksunie is suffering a serious setback, that is certainly benefitting to the Vlaams Blok, which, however, is also attracting voters from different political origins on issues similar to those of the far right.The analysis also contains a comparison between the results of the European election and those of the election for the Council of the Brussels-Capital Region, in a set of three districts where the voters were exactly the same.

This review discusses Vincent Blok’s book Heidegger’s Concept of Philosophical Method. Blok’s daring and important argument is that Heidegger has been misunderstood by contemporary philosophers who dismiss his thinking as correlationism; but that at the same time there lies something at the core of Heidegger’s thinking that prevents it from unleashing its true innovative potential; namely a logic of unity. To move beyond this logic of unity, Blok aims to rediscover and redefine the potential of Heidegger’s philosophical (...) method by characterising it along the lines of interrogative intention and creativity of world-interest. This move allows Blok to think about Earth in the age of global warming in a way that was not possible in Heidegger’s work, providing a positive concept of the Earth’s materiality as uncorrelated being that guides the way to a future environmental ethics. The review discusses the main contributions of the book, and also three criticisms, which concern the justification of choices for certain perspectives, the unfulfilled promise of moving from philosophical theory to more practically oriented guidance, and unclarities concerning the alternative that Blok puts forward as an answer to his criticism of Heidegger’s method.
