The main aim of this study is to explain passage 35b4-37a2 of Plato’s Timaeus which deals with three main topics: the mathematization of the world’s soul, its movement, and its binding to the world’s body. First, it is argued that the mathematical structure of the world-soul allows it to participate in and be sensitive to harmony, which is essential for the correct workings of its cognitive capacities. Second, the division of the world-soul to the circle of the same and the (...) circles of the different and its self-motion comes in. This allows it to ‘touch’ and cognize the forms and the material things, as well as rule the movement of the corporeal world and care for it. In this aspect, the world-soul continues the process that started with the original creative act of the demiurge. Third, it is argued that the description of the world-soul’s binding to the world-body entails its conception as a spatially extended entity, which, in turn, explains of the possibility of an interaction between the corporeal world and its soul.

The eternalist endurantist and perdurantist theories of persistence through time come in various versions, namely the two versions of perdurantism: the worm view and the stage view , and the two versions of endurantism: indexicalism and adverbialism . Using as a starting point the instructive case of what is depicted by photographs, I will examine these four views, and compare them, with some interesting results. Notably, we will see that two traditional enemies—the perdurantist worm view and the endurantist theories—are more (...) like allies : they are much less different than what is usually thought, and some alleged points of central disagreement fall prey to closer scrutiny. The aim of this paper is to examine carefully all those points, and to call attention to the places where the real differences between these views lie. I will then turn to the perdurantist stage view, and claim that with respect to some central issues it is the view that is the most different from the other three, but that in some places the reason why it different is also the reason why it is less satisfactory.

Metaphysical theories are beautiful. At the end of this book, Jiri Benovsky defends the view that metaphysical theories possess aesthetic properties and that these play a crucial role when it comes to theory evaluation and theory choice.Before we get there, the philosophical path the author proposes to follow starts with three discussions of metaphysical equivalence. Benovsky argues that there are cases of metaphysical equivalence, cases of partial metaphysical equivalence, as well as interesting cases of theories that are not equivalent. Thus, (...) claims of metaphysical equivalence can only be raised locally. The slogan is: the best way to do meta-metaphysics is to do first-level metaphysics.To do this work, Benovsky focuses on the nature of primitives and on the role they play in each of the theories involved. He emphasizes the utmost importance of primitives in the construction of metaphysical theories and in the subsequent evaluation of them.He then raises the simple but complicated question: how to make a choice between competing metaphysical theories? If two theories are equivalent, then perhaps we do not need to make a choice. But what about all the other cases of non-equivalent "equally good" theories? Benovsky uses some of the theories discussed in the first part of the book as examples and examines some traditional meta-theoretical criteria for theory choice (various kinds of simplicity, compatibility with physics, compatibility with intuitions, explanatory power, internal consistency,...) only to show that they do not allow us to make a choice.But if the standard meta-theoretical criteria cannot help us in deciding between competing non-equivalent metaphysical theories, how then shall we make that choice? This is where Benovsky argues that metaphysical theories possess aesthetic properties – grounded in non-aesthetic properties – and that these play a crucial role in theory choice and evaluation. This view, as well as all the meta-metaphysical considerations discussed throughout the book, then naturally lead the author to a form of anti-realism, and at the end of the journey he offers reasons to think better of the kind of anti-realist view he proposes to embrace. www.jiribenovsky.org.

The paper deals with the problematic of concept and image as independent forms of mediating the thought. A specific role in incorporating the media of concept and image into the system of thought is played by the mediality itself, which operates as an entity mediating between heterogeneous worlds. The symbolized messages of the concept and image thus represent using the dispositive of representation between the visual and intellectual worlds. The author takes the concept as the initial form of thought, which (...) describes the object from the perspective of its being without making any propositions about it; the image, on the other hand, is taken as a sensory representation of the object. However, each of them is only a particular form of mediation. Representing a concept thus means taking the thought as a conceptual representation. (shrink)

We investigate the interactions of formula complexity in weak set theories with the axioms available there. In particular, we show that swapping bounded and unbounded quantification preserves formula complexity in presence of the axiom of foundation weakened to an arbitrary set base, while it does not if the axiom of foundation is further weakened to a proper class base. More attention is being paid to the necessary axioms employed in the positive results, than to the combinatorial strength of the positive (...) results themselves. (shrink)

Cílem této studie je představení základních tezí sociálně-politické filosofie Karla Raimunda Poppera (jak je zachycena zejména v dílech Bída historicismu a Otevřená společnost a její nepřátelé) a dále kritické zhodnocení aplikace těchto tezí při výkladu Platónovy filosofie. Je probíráno zejména Popperovo obvinění Platóna z tzv. „biologického historicismu“, dále jeho označení platónské teorie spravedlnosti jako „totalitní“ a v neposlední řadě jeho interpretace dialogu Ústava jakožto Platónova „politického programu“ určeného k přímé implementaci v praxi vyvoleným filosofem-králem. V druhé polovině této studie je (...) pak nabídnuto alternativní čtení, v němž se Platónova Ústava vyjeví ve zcela odlišném světle, než v jakém ji vidí Popper. (shrink)

In this book, Jiri Benovsky defends the view that he doesn't exist. In this book, he also defends the view that this book itself doesn't exist. But this did not prevent him to write the book, and although in Benovsky's view you don't exist either, this does not prevent you to read it. Benovsky defends a brand of non-exceptionalist eliminativism. Some eliminativists, typically focusing on ordinary material objects such as chairs and hammers, make exceptions, for instance for blue whales (that (...) is, living beings) or for persons (that is, conscious organisms). Benovsky takes one by one all types of allegedly existing objects like chairs, whales, and persons and shows that from the metaphysical point of view they are more trouble than they are worth – we are much better off without them. He thus defends an eliminativist view about ordinary objects as well as the 'no-Self' view, where he explores connections between metaphysics, phenomenology, and Buddhist thought. He then also considers the case of aesthetic objects, focusing on musical works and photographs, and shows that the claim of their non-existence solves the many problems that arise when one tries to find an appropriate ontological category for them, and that such an eliminativist view is more natural than what we might have thought. The arguments provided here are always topic-specific: each type of entity is given its own type of treatment, thus proving a varied and solid foundation for a generalized, non-exceptionalist, full-blown eliminativist worldview.

This paper is about our experience of change and movement, and thus about our experience of time – at least under the reasonable assumption that we (can only) experience time by having experiences of change. This assumption is shared by Locke, whose view on temporal experience, expounded in Book II, Chap.14 of his Essay, will be the main focal point of my paper. Some of the most influential accounts of temporal experience embrace the notion of a "specious present" as an (...) explanatory tool in order to account for the continuous and unfolding aspect of our experiences. In this article, I will raise some points of dissatisfaction with the very notion of the specious present, and while I shall not reject the specious present theories, I will argue that more is needed in order to have a proper understanding and explanation of our temporal experience. I will then discuss and defend a view of temporal experience whose basis can be found in Locke's Essay, and which, given some amendments and further development within a contemporary framework, provides us with a very good analysis of our experience of movement, change, and time – a view that helps us to avoid some burdensome commitments incurred by specious present theories and that can be fruitfully combined with these theories in order to yield a complete and more informative picture of the phenomenon of temporal experience.

A bare individual was conceived by Tichý as an individual such as if the property the individual instantiates is non-trivial , it is possible for the individual to lack it ; and for any trivial property that it cannot lack this kind of property. The exact readings of Tichý’s original formulations of are subjected to a detailed analysis to reveal that any of them is refutable by means of Cmorejian objection that there exist contingent properties which are partly essential . (...) To avoid such objection, the present paper attempts to rebuild Tichý’s definitions into viable ones. (shrink)

The claim that the having of aesthetic properties supervenes on the having of non-aesthetic properties has been widely discussed and, in various ways, defended. In this paper, I will show that even if it is sometimes true that a supervenience relation holds between aesthetic properties and the 'subvenient' non-aesthetic ones, it is not the interesting relation in the neighbourhood. As we shall see, a richer, asymmetric and irreflexive relation is required, and I shall defend the claim that the more-and-more-popular relation (...) of grounding does a much better job than supervenience.

How do ordinary objects persist through time and across possible worlds ? How do they manage to have their temporal and modal properties ? These are the questions adressed in this book which is a "guided tour of theories of persistence". The book is divided in two parts. In the first, the two traditional accounts of persistence through time (endurantism and perdurantism) are combined with presentism and eternalism to yield four different views, and their variants. The resulting views are then (...) examined in turn, in order to see which combinations are appealing and which are not. It is argued that the 'worm view' variant of eternalist perdurantism is superior to the other alternatives. In the second part of the book, the same strategy is applied to the combinations of views about persistence across possible worlds (trans-world identity, counterpart theory, modal perdurants) and views about the nature of worlds, mainly modal realism and abstractionism. Not only all the traditional and well-known views, but also some more original ones, are examined and their pros and cons are carefully weighted. Here again, it is argued that perdurance seems to be the best strategy available. (shrink)

The paper discusses Kant’s distinction between appearances and things in themselves, phenomena and noumena, and the problem of affection. The difference between appearances and things in themselves is understood as a methodological difference between two manners in which an object can be viewed: either as an appearance, or as a thing in itself. The author claims that this double-aspect view is a consequence of Kant’s conception of space and time as a priori forms of sensibility. The difference between phenomena and (...) noumena, on the other hand, cannot be explained only by the double-aspect view; Kant understands it also as an ontological difference between two different kinds of objects. The paper concludes with a discussion of the problem of affection. The author claims that this problem is a pseudo-problem if we understand the difference between appearances and things in themselves as double-aspect view. Kant had maintained only an empirical affection. Passages in which Kant seems to advocate a transcendental affection can be brought in line with Kant’s critical philosophy. (shrink)

The study discusses Kant’s doctrine of lasting peace contained in his essay Toward Perpetual Peace (1795). First, the historical-political circumstances surrounding the genesis of Kant’s essay are described. Kant’s preliminary measures, which in his opinion must be accepted if lasting peace is to be ensured, are also discussed. Great attention is paid to the very core of Kant’s essay: his proposal for a comprehensive reform of law, which should apply to state, international, and cosmopolitan law. This is followed by an (...) exposition of Kant’s reflections on the feasibility of his doctrine of lasting peace in history. And finally, Kant’s view of the public as an institution is summarized. The originality of Kant’s approach is seen by the author above all in the fact that, from the point of view of the philosophy of law, the doctrine of lasting peace in Toward Perpetual Peace is connected with a consideration regarding its realizability in history. He also draws attention to the fact that though this detail is known, it is often marginalized in secondary literature. (shrink)

History and the philosophy of science have played a very important role in dialectical materialism; their results have been destined to support the correctness of the ideas of Marxist philosophers, especially in their application in historical materialism.From this point of view, the circumstances of the origin of the works of the Marxist classics cannot be neglected: Engels wrote hisDialectics in Nature in the period of classical physics, and Lenin published hisMaterialism and Empirio-Criticism at the beginning of the 20th century when (...) our modern physics first began: shortly before the publication of Lenin's book, Röntgen and Becquerel discovered new kinds of radiation, Balmer published his ideas concerning the regularity of the hydrogen spectrum, Plank wrote his first articles about the elementary quantum and Einstein published his three famous articles (1905).

Studie ukazuje, jak se problém vůle stával pro Heideggera v jeho zralém bytostně dějinném myšlení problematickým. Heidegger se pozvolna zbavoval (od poloviny třicátých let) voluntárního přístupu ke jsoucnu, v bytostně dějinném obratu spěl k ryzímu ne-chtění. Začal se rýsovat odstup od světa svévolné vědotechniky směrem k větší otevřenosti vůči bytí. K tomu je zapotřebí nacházet ryzí tubytí (Da-sein) a přibližovat se k původnímu bytí samému (Seyn). Tehdy se může otevírat ne-voluntární smysl uvlastňování bytí, kdy se překračuje novověka subjektivita a s (...) ní také technologický nihilismus doby; jde se spíše cestou "myšlení a básnění", cestou odevzdanosti (Gelassenheit) a ne-chtění. Jen tak se může otevřít zóna opravdového života, kdy člověka nesemele mechanismus technickéhop zjednávání (Gestell) a mechnaisticky subjektivistická vůle k moci a vůle k vůli. (shrink)

Během nedávno započaté hospodářské krize se paralelně s aplikací netradičních hospodářských politik zvýšil tlak na potlačení ortodoxních ekonomických teorií hlavního proudu a po několika desetiletích se v ekonomii znovu otevírá prostor pro nové teorie, metodologie, paradigmata. Cíle této práce jsou tři. Cílem prvním je obecná sumarizace základních východisek post keynesiánské ekonomické metodologie. Cílem druhým je pak jasné vymezení této heterogenní teorie vůči neoklasické metodologii s ambicí zcela od základů alternovat tuto starou metodologii. A konečně cílem třetím je analýza architektury post (...) keynesiánské makroekonomické metodologie včetně její primární metody zkoumání. Ta je spojena zejména s kritikou absence realismu v neoklasické ekonomii. (shrink)

In this paper, I explore several versions of the bundle theory and the substratum theory and compare them, with the surprising result that it seems to be true that they are equivalent (in a sense of 'equivalent' to be specified). In order to see whether this is correct or not, I go through several steps : first, I examine different versions of the bundle theory with tropes and compare them to the substratum theory with tropes by going through various standard (...) objections and arguing for a tu quoque in all cases. Emphasizing the theoretical role of the substratum and of the relation of compresence, I defend the claim that these views are equivalent for all theoretical purposes. I then examine two different versions of the bundle theory with universals, and show that one of them is, here again, equivalent to the substratum theory with universals, by examining how both views face the famous objection from Identity of Indiscernibles in a completely parallel way. It is only the second, quite extreme and puzzling, version of the bundle theory with universals that is not be equivalent to any other view; and the diagnosis of why this is so will show just how unpalatable the view is. Similarly, only a not-so-palatable version of the substratum theory is genuinely different from the other views; and here again it's precisely what makes it different that makes it less appealing.

The practice of attributing aesthetic properties to scientific and philosophical theories is commonplace. Perhaps one of the most famous examples of such an aesthetic judgement about a theory is Quine's in 'On what there is': "Wyman's overpopulated universe is in many ways unlovely. It offends the aesthetic sense of us who have a taste for desert landscapes". Many other philosophers and scientists, before and after Quine, have attributed aesthetic properties to particular theories they are defending or rejecting. One often hears (...) that a view is "elegant", "attractive", "beautiful", or even "sexy". [...] The general claim that aesthetic properties supervene on non-aesthetic properties is a largely debated one. In this paper, I wish to address this issue from an angle which has not been really explored so far: I shall neither concentrate on cases of artefacts nor of natural objects, like the beauty of a painting or the beauty of a sunrise, rather, my main centre of attention will be the somewhat more special, theoretical case of the beauty of philosophical theories (with a focus on metaphysical theories). As we will see, there are some interesting issues concerning claims that attribute aesthetic properties to theories, in part because, even if such claims are commonplace in philosophy and in science, little has been said about the nature of the relevant supervenience basis – that is, about what it is exactly that the beauty of a theory is supposed to supervene on. Moreover, we shall see that aesthetic properties of theories play a crucial role in theory choice and evaluation. Indeed, it seems that the aesthetic properties of a theory can be appealed to in theory evaluation and when it comes to preferring one theory over another. But before we ask ourselves what role the attribution of aesthetic properties to theories can play, I will adress the question how theories come to have their aesthetic properties in the first place.

Přehledová studie sleduje a analyzuje proměny pojmu sociální inovace. Na základě silné společenské poptávky se z původně dílčí, teoreticky nediskutované a nefixované kategorie stává kategorie obecná. Pokrývá širokou oblast nemateriálních inovací a zároveň se profiluje jako aktivita normativní a intencionální, zaměřená na obecně uznávané sociální cíle. Co do ideově-hodnotových orientací současných koncepcí sociálních inovací studie identifikuje kromě mainstreamu, který zůstává u otevřených hodnotových charakteristik, ještě směr emancipačně-mobilizační a sociálně-tržně odpovědný. V epistemologické rovině se teoretici sociálních inovací hlásí především k praktickému (...) experimentování, pragmatismu, teorii komplexnosti a principům transdisciplinarity. (shrink)

We study search problems and reducibilities between them with known or potential relevance to bounded arithmetic theories. Our primary objective is to understand the sets of low complexity consequences of theories Si2 and Ti2 for a small i, ideally in a rather strong sense of characterization; or, at least, in the standard sense of axiomatization. We also strive for maximum combinatorial simplicity of the characterizations and axiomatizations, eventually sufficient to prove conjectured separation results. To this end two techniques based on (...) the Herbrand's theorem are developed. They characterize/axiomatize Σb1-consequences of Σb2-definable search problems, while the method based on the more involved concept of characterization is easier and gives more transparent results. This method yields new proofs of Buss' witnessing theorem and of the relation between PLS and Σb1, and also an axiomatization of Σb1. (shrink)

Model-theoretic concepts of saturation and categoricity are studied in the context of accessible categories. Accessible categories which are categorical in a strong sense are related to categories of $M$-sets ($M$ is a monoid). Typical examples of such categories are categories of $\lambda$-saturated objects.
