A fundamental assumption of theories of decision-making is that we detect mismatches between intention and outcome, adjust our behavior in the face of error, and adapt to changing circumstances. Is this always the case? We investigated the relation between intention, choice, and introspection. Participants made choices between presented face pairs on the basis of attractiveness, while we covertly manipulated the relationship between choice and outcome that they experienced. Participants failed to notice conspicuous mismatches between their intended choice and the outcome (...) they were presented with, while nevertheless offering introspectively derived reasons for why they chose the way they did. We call this effect choice blindness. (shrink)

It is widely accepted that if a property is essential then it is necessary. Against this I present numerous counterexamples from biology and chemistry, which fall into two groups: (I) A property is essential to a genus or species, yet some instances of this genus or species do not have this essential property. (II) A property is essential to a genus, yet some species of this genus do not have this essential property. I discuss and reject four minor objections. Then (...) I discuss in depth whether a distinction between constitutive essence and consequential essence is able to handle these counterexamples. I conclude that this distinction is better put as one between (1) the essence, which is necessary, and (2) the essential properties, which are not formally necessary. An essence of an object X is the substantial universal expressed by its real definition. An object X has a property P essentially iff the property P is explanatory and non-trivial, and P follows from the essence of X. (shrink)

Exceptions are often cited as a counterargument against formal causation. Against this I argue that Aristotle explicitly allows for exceptions to essences in his biological writings, and that he has a means of explaining them through formal causation – though this means that he has to slightly elaborate on his general case theory from the Posterior Analytics, by supplementing it with a special case application in the biological writings. Specifically for Aristotle an essential predication need not be a universal predication. (...) Rather an essential predication is where a property belongs essentially to a species or genus. This essential predication serves a causal and explanatory role, and is not dependent on a corresponding universal predication. (shrink)

I argue that Aristotle’s account of scientific demonstrations in the Posterior Analytics is centred upon formal causation, understood as a demonstration in terms of essence (and as innocent of the distinction between form and matter). While Aristotle says that all four causes can be signified by the middle term in a demonstrative syllogism, and he discusses at some length efficient causation, much of Aristotle’s discussion is foremost concerned with the formal cause. Further, I show that Aristotle had very detailed procedures (...) for identifying the formal cause, and that he is aware of several problems which might lead one to erroneously identify the wrong form as the cause of a property. Finally, I show that Aristotle’s account can easily be adapted to material causation, and through some modifications (introduction of process universals related through parthood), hinted at in II 11-12 and 16-17, to efficient and final causation.

Every day, thousands of polls, surveys, and rating scales are employed to elicit the attitudes of humankind. Given the ubiquitous use of these instruments, it seems we ought to have firm answers to what is measured by them, but unfortunately we do not. To help remedy this situation, we present a novel approach to investigate the nature of attitudes. We created a self-transforming paper survey of moral opinions, covering both foundational principles, and current dilemmas hotly debated in the media. This (...) survey used a magic trick to expose participants to a reversal of their previously stated attitudes, allowing us to record whether they were prepared to endorse and argue for the opposite view of what they had stated only moments ago. The result showed that the majority of the reversals remained undetected, and a full 69% of the participants failed to detect at least one of two changes. In addition, participants often constructed coherent and unequivocal arguments supporting the opposite of their original position. These results suggest a dramatic potential for flexibility in our moral attitudes, and indicates a clear role for self-attribution and post-hoc rationalization in attitude formation and change.

A Norwegian translation is here offered of Eugenie Ginsberg’s paper «Zur Husserlschen Lehre von den Ganzen und den Teilen» (in Archiv für systematische Philosophie und Soziologie 32, 1929, 108–120). The paper discusses Husserl’s six theorems from Logical Investigations III, §14. Ginsberg provides new proofs for theorems 1 and 3, and also endorses theorem 5. In contrast, a counter example is given to theorems 2, 4, and 6: However, proofs are supplied for a modified version of these theorems. Furthermore, an additional (...) three theorems are defended based upon Ginsberg’s modified theorems. Also, a brief introduction is given discussing Ginsberg’s pioneering role as part of the Lvov-Warsaw school—in spite of her being murdered by the Nazis in 1942—especially her role as the first commentator on Husserl’s third logical investigations, which is a pioneering work on mereology and ontology; but also her later publication from 1931 where she developed several notions of ontological dependence (for instance foreshadowing the work of Roman Ingarden as well as Kit Fine).

Political candidates often believe they must focus their campaign efforts on a small number of swing voters open for ideological change. Based on the wisdom of opinion polls, this might seem like a good idea. But do most voters really hold their political attitudes so firmly that they are unreceptive to persuasion? We tested this premise during the most recent general election in Sweden, in which a left- and a right-wing coalition were locked in a close race. We asked our (...) participants to state their voter intention, and presented them with a political survey of wedge issues between the two coalitions. Using a sleight-of-hand we then altered their replies to place them in the opposite political camp, and invited them to reason about their attitudes on the manipulated issues. Finally, we summarized their survey score, and asked for their voter intention again. The results showed that no more than 22% of the manipulated replies were detected, and that a full 92% of the participants accepted and endorsed our altered political survey score. Furthermore, the final voter intention question indicated that as many as 48% (69.2%) were willing to consider a left-right coalition shift. This can be contrasted with the established polls tracking the Swedish election, which registered maximally 10% voters open for a swing. Our results indicate that political attitudes and partisan divisions can be far more flexible than what is assumed by the polls, and that people can reason about the factual issues of the campaign with considerable openness to change.

The project “A Plurality of Lives” was funded and hosted by the Pufendorf Institute for Advanced Studies at Lund University, Sweden. The aim of the project was to better understand how a second origin of life, either in the form of a discovery of extraterrestrial life, life developed in a laboratory, or machines equipped with abilities previously only ascribed to living beings, will change how we understand and relate to life. Because of the inherently interdisciplinary nature of the project aim, (...) the project took an interdisciplinary approach with a research group made up of 12 senior researchers representing 12 different disciplines. The project resulted in a joint volume, an international symposium, several new projects, and a network of researchers in the field, all continuing to communicate about and advance the aim of the project.

Julkaisematta jääneessä muistiossaan Mietteitä oikeuden yleiskäsitteestä (1702-1703?) G. W. Leibniz muotoilee uudelleen Platonin Euthyfron-dialogissa esitetyn kuuluisan kysymyksen. Hän kirjoittaa: ”Myönnetään, että kaikki mitä Jumala tahtoo, on hyvää ja oikein. Sen sijaan kysytään, onko se hyvää ja oikein siksi että Jumala niin tahtoo, vai tahtooko Jumala sitä koska se on hyvää ja oikein. Eli kysytään, onko hyvyys tai oikeus jotakin mielivaltaista, vai koostuvatko ne asioiden luonnetta koskevista välttämättömistä ja ikuisista totuuksista, kuten luvut ja suhteet.” Universaaleja, ikuisia totuuksia puolustava filosofi ei voi (...) hyväksyä ensin mainittua vaihtoehtoa. Hänen mukaansa ”Se toden totta tuhoaisi Jumalan oikeudenmukaisuuden. Sillä miksi ylistäisimme häntä oikeudenmukaisista teoista, jos oikeudenmukaisuuden käsite ei hänen tapauksessaan lisää mitään teon käsitteeseen? Ja sanonta stat pro ratione voluntas, minun tahtoni käyköön perusteesta, on todella tyrannin motto.” Leibnizin kritiikki on suunnattu erityisesti hänen aikalaisiaan René Descartesia, Thomas Hobbesia ja Samuel Pufendorfia vastaan. Hän ei voi hyväksyä näkemystä, jonka mukaan oikeudenmukaisuuden mitta on vain Jumalan tahto. Perustan on löydyttävä ikuisista totuuksista, jotka ovat myös Jumalan oikeudenmukaisuuden standardi. Erityisen kuuluisaksi tuli Leibnizin kritiikki Pufendorfin näkemyksiä kohtaan, sillä Pufendorfin laajalle levinneen teoksen De officio hominis et civis ranskalaisen laitoksen neljännen painoksen toimittaja Barbeyrac liitti siihen Leibnizin kiistakirjoituksen, joka tunnetaan lyhyellä nimellä Monita (Epistola viri excellentissimi ad amicum qua monita quaedam ad principia Pufendorfiani operis de officio hominis et civis continentur, 1706) ja puolusti Pufendorfia Leibnizia vastaan. Leibnizin onnistui kuitenkin ilmeisesti osoittaa eräs heikkous Pufendorfin näkemyksissä, jota Barbeyrac ei pystynyt sivuuttamaan: tämän mukaan Jumala on saman aikaan sekä ylin tuomari että lakien laatija. Siten Leibnizin näkökulmasta Jumala on tyranni – hänen tahtonsa on oikeuden ja etiikan mitta ja koska hän on kaikkivaltias, hän voi pakottaa ihmiset noudattamaan sellaista oikeudenmukaisuutta, joka on hänen mieleistään. Koska Jumalan yläpuolella ei ole Pufendorfin mukaan mitään, hän voi toimia aivan mielivaltaisesti. Leibnizin kritiikki kiteytyy Pufendorfin epäselvään erotteluun ulkoisen ja sisäisen velvollisuuden välillä, joka jättää hänen näkemyksensä arvoitukselliseksi. Tutkiskelen tässä esitelmässä oliko Leibnzin kritiikki johdonmukainen ja oikeutettu. Onko Pufendorfin näkemyksissä heikkous, jota hän ei itse huomannut? Vertailen myös asiaa koskevia eri kommentaareja (mm. Kari Saastamoinen, Petter Korkman, Fiametta Palladini) ja arvioin Leibnizin kritiikin reseptiota Pufendorf-tutkimuksessa. (shrink)
