The present PhD dissertation aims to examine the relation between modality and change in Aristotle’s metaphysics. -/- On the one hand, Aristotle supports his modal realism (i.e., worldly objects have modal properties - potentialities and essences - that ground the ascriptions of possibility and necessity) by arguing that the rejection of modal realism makes change inexplicable, or, worse, banishes it from the realm of reality. On the other hand, the Stagirite analyses processes by means of modal notions (‘change is the (...) actuality of what is virtual insofar as it is virtual’). In other words: to grasp what change is, one has to resort to the modal idiom of potentialities, while the fact that there is change is indicative of the fact that nature is full of modal properties. -/- Aristotle’s modal and kinetic realism finds a negative in the figure of the Megaric Diodorus Kronus. The polemical situation of Greek philosophy has indeed the dialectical advantage of not opposing the Aristotelian position to a sui generis straw man. Both in its reduction of modal judgements to temporal quantifications and in its dissolution of the reality of the state-of-being-in-motion in favour of a cinematographic view of processes, the philosophical figure of reductionist antirealism embodied by Diodorus constitutes an alternative that takes the opposite view of Aristotle’s realism. -/- The present study is structured as a discussion between these two positions. In the face of Diodorus’ antirealist challenges, Aristotle articulates modal and kinetic considerations: the answers he gives to Diodorus’ puzzles thus provide valuable insight into his metaphysics. Moreover, the examination of Aristotle’s and Diodorus’ metaphysics, because of their insight and originality, will not fail to interest the philosopher concerned with the metaphysical foundations of modern physics, insofar as the entanglement between modalities and processes is nowadays at the core of mechanics (phase spaces, path integrals, etc.).

Philosophical debate about the nature and function of thought experiments would be impoverished without good historical sources. And while valuable work is being done on the history of thought experiments, a comprehensive discussion of the history of philosophical investigation into thought experiments is still absent in the literature (but see Kühne 2005; Moue et al. 2006). In what follows we take the first steps towards providing a more complete picture of the diverse attempts to shed light on thought experiments.The term (...) “thought experiment” made its first appearance about 200 years ago in 1811. The most prolific period in the history of the philosophical investigation into thought experiments is the current .. (shrink)

This is an introduction to a special issue of Perspectives on Science, the outcome of a workshop entitled "Thought Experiments in Science: Four Blind Spots," held at the University of Toronto, March 23rd, 2012. The recent revival in philosophical study of thought experiments has been limited to fields like epistemology, science studies, and metaphilosophy. With this issue we hope to facilitate a discussion about how some other disciplinary perspectives might bear on the subject; specifically, the history of philosophy, literary studies, (...) phenomenology and cognitive science.

Zombeja käsittelevät televisiosarjat ja sarjakuvat ovat viime vuosina saavuttaneet suurta suosiota. Esimerkiksi The Walking Dead -sarjan ensimmäinen jakso näytettiin samanaikaisesti 120 maassa, ja sarjaa on sittemmin katsonut tuotantokaudesta riippuen 5–15 miljoonaa katsojaa. Post-apokalyptinen maailma kiehtoo suurta yleisöä, koska dystooppiset tarinat peilaavat erilaisia käsityksiä ihmisten perusolemuksesta ja yhteiskunnan perustasta; sarjaa voi pitää filosofisena ajatuskokeena, jolla testataan, miten erilaiset näkemykset toimisivat luonnontilaan paluun jälkeen. Artikkelimme lähtökohta on, että zombikuvasto tarjoaa hedelmällisen tilaisuuden filosofiselle analyysille. Tarkastelemme yhteiskunnan romahtamisen jälkeistä tilaa yhteiskuntafilosofian klassikoiden, Aristoteleen ja (...) Thomas Hobbesin avulla. Pyrimme osoittamaan, että Hobbesin luonnontilan käsitteen rinnalla Aristoteleen eettiset ja yhteiskuntafilosofiset näkemykset tarjoavat hyödyllisen näkökulman sivilisaation romahduksen jälkeisen kuvitteellisen tilanteen ymmärtämiseen. Täydennämme analyysia sosiaalipsykologi Erich Frommin yhteiskuntaluonteen käsitteellä ja osoitamme, että dystopiaan sisältyy lupaus utopiasta, paremmasta maailmasta. Yleisesti ottaen esitämme, että populaarikulttuurin ja filosofian yhdistäminen tarjoaa oivaltavan näkökulman nykyisen länsimaisen ihmiskuvan peruselementtien ymmärtämiseen. (shrink)
