PhDr. Tomáš Kunca The Humanist Virtuoso: Beginnings, Idea and Illustration of Hume's experimental philosophical anthropology in Treatise of Human Nature UK FHS, Praha 2013 Thesis introduces a concept of "The Humanist Virtuoso" as distinctive feature reflecting Hume's effort to introduce an idea of experimental philosophical anthropology based on study of human nature and manifested in his A Treatise of Human Nature. Concept is justified by three steps, through analysis of the beginnings of Hume's philosophy, explication of his "science of man" idea in Treatise and illustration of this idea in action, as appears in analysis of passions (Book 2). The beginnings of Hume's way to experimental philosophical anthropology are explained thorough interpretation of historical facts connected with his early study at College of Edinburgh. First meetings with culture of science ( both British Christian tradition of experimental philosophy and Newtonian mathematical philosophy) are considered as particularly important. Detailed analysis of pre-Treatise letters (the Letter to Physician and to Michael Ramsey) is provided to make explicit the beginnings of his "science of man" idea, turn to study of human nature. Castration of Treatise is observed and discussed via analysis of his letter to Home (1737). The second...

Chandra Sripada's (2010) Deep Self Concordance Account aims to explain various asymmetries in people's judgments of intentional action. On this account, people distinguish between an agent's active and deep self; attitude attributions to the agent's deep self are then presumed to play a causal role in people's intentionality ascriptions. Two judgments are supposed to play a role in these attributions-a judgment that specifies the attitude at issue and one that indicates that the attitude is robust (Sripada & Konrath, 2011). In this article, we show that the Deep Self Concordance Account, as it is currently articulated, is unacceptable.

[pt] Embora as sanções estejam bastante presentes nas experiências jurídicas ao redor do mundo, durante muito tempo o tema foi negligenciado pelos teóricos analíticos do direito. O motivo é o entendimento corrente de que a sanção não é um elemento necessário para a normatividade jurídica e que, portanto, não é objeto da jusfilosofia. O direito, no entanto,é melhor explicado não apenas pelo estudo das características necessárias e suficientes, mas pela observação de seus aspectos considerados importantes.Se o trabalho do jusfilósofo é conceituar ou descrever o fenômeno jurídico, ou fornecer material normativo para aqueles que vivem a experiência jurídica, ele deve compreender essas características que se mantêm presentes em vários ordenamentos.Com esse foco, este trabalho utiliza uma abordagem interdisciplinar para estudar as sanções. As sanções geralmente são usadas como estímulo para o cumprimento de regras. Experimentos com jogos econômicos têm confirmado a eficiência dessa prática. Há, contudo, casos em que a introdução de sanções produz o resultado contrário ao pretendido. Como o uso de regras tem um valor positivo para a coletividade, o estudo sobre a forma como as pessoas compreendem o emprego de sanções pode ajudar a melhorar a produção legislativa. A despeito da discussão normativa, estudos psicológicos apontam para uma tendência punitiva retributivista no julgamento das pessoas comuns. Além disso, a psicologia tem indicado algumas assimetrias no comportamento punitivo.O filósofo do direito deveria fazer um esforço para integrar as diferentes informações para fornecer explicações mais adequadas do fenômeno jurídico e para construir teorias normativas mais factíveis. / [en] Although sanctions are a constant presence on law systems around the world, the analytic philosophers of law neglected this subject for a long time. The reason is that sanctions were though as an unnecessary element to explain legal normativity. However, law is better explained by the observation of what is understood as its important features and not by its necessary and sufficient ones. If the work of those philosophers its to conceptualize or to describe the legal phenomenon, or to provide normative material, they must comprehend features that are presents in almost every legal system. Following this line of thought, this study is an interdisciplinary approach to sanctions. The sanctions are usually used as incentives for rules observance. Experiments made of economic games have confirmed the efficiency of this method. There are, nevertheless, cases in which sanctions make the opposite result that is expected. As much as rules have a positive value for society, the study about the way people understand the use of sanctions can help improve legal production. Despite the normative debate, psychological studies are pointing to a retributivist tendency in folk people punitive judgments. Besides that, psychology has showed some asymmetries in punitive behavior. The philosopher of law should make an effort to integrate different information in order to provide more accurate explanations to the legal phenomenon and create more feasible normative theories.

The normative moral code is considered to be such that it applies universally to all or at least to all who can understand and govern their behavior by it. All or almost all common folk think of and use their own moral codes as them being normative in that for example there simply seem to them to exist “oughts” that apply to all and that there simply, straightforwardly are “things” that are right and wrong, good and bad. Gert Bernard and Gert Joshua have written an article on the topic of defining morality, with the title of “The Definition of Morality”. The authors suggest that the terms ‘normative morality’ refer to a code of conduct that, given some specified conditions, would be put forward by all rational persons. The authors take this formulation as entailing true and important definitional features of what normative morality is, although the authors think of this basic definition, conception as not being complete and that some additional feature hence is lacking but that any such candidate addendum to the definitional basic schema that they surveyed within the article seemed to be controversial, contested. Normative morality seems apt to investigate by creating thought-experiments wherein the participants are for example, envisioned choosing to endorse, put forward or act in accordance with a moral code. Within this large investigative project into normative morality with the help of thought-experiments it seemed to me that there was an under-representation of thought-experiments exhibiting some worthwhile and relevant features and I felt that it was a warranted project to create a thought-experiment which concurrently exhibited these features. Such an experiment could be thought of as an unusual “puzzle-piece” which could be valuable in contributing to furthering the completion of the “puzzle”, i.e. what normative morality is and its moral code. These three features were: i) a high degree of aptness for investigating a major part of or the complete normative moral code and ii) a high degree of freedom pertaining to the participants, e.g. their actions, thoughts etc., as well as iii) a high degree of confidence or warrant concerning what the participants would do, think, feel etc. within the thought-experiment. A thought-experiment, the Normative Moral Codes Workshop (NMCW) was hence created, which was aimed at investigating normative morality and its code and which exhibited these features. It is a thought-experiment mimicking an actual empirical study wherein the participants are given the task to together put forward the moral code for them, that would apply to them and that would cover a major or complete part of what they consider their moral codes to entail. The participants employed within my run of the NMCW thought-experiment were all currently living adult persons who I knew well. The core or main aim of this essay was to investigate whether it would or would not be the case that most or all participants within my run of the thought-experiment the NMCW would decide to put forward the code together with the chosen formulation of the thesis being, that it would not be the case that most or all participants would put forward the code within my run of the NMCW thought-experiment. Part of the core aim was also to elucidate why the thesis was supported or not supported as well as how strong the support was for the outcome of the experiment, i.e. the outcome of a code being put forward or not. The essay also has some minor aims which radiate out from the core aim (see below). As the thought-experimenter, I then reported on the events that I envisioned as happening within my run the NMCW thought-experiment as my selected participants grappled with the task and their decision to put or not put forward the code together that would apply to them. The finding was that the thesis was supported and that the support was robust in that I could identify several reasons the participants had against putting forward the code and I found very little in terms of reasons among the participants for putting forward the code. The essay also had some minor aims to selectively discuss a few further relevant and interesting issues radiating out from the core aim. These minor aims revolved around discussing some selected salient features of the NMCW including how they could relate to the outcome. One such selected salient feature was the feature of the employed participant sample of my run of the NMCW. I for example, discussed the potential extension of it not being the case that most or all participants would decide to put forward the code, if the participant sample would have been modified but still employed currently living5adults and I ended up being of the opinion that pertaining to most potential samples a similar outcome as the one envisioned within my run of the NMCW would be expected. I also wanted to discuss some further selected salient features of the NMCW within the context of addressing whether the NMCW, given its features ought to be considered an unsound, inapt experiment for investigating normative morality, given Gert’s and Gert’s conception of normative morality, since if this was the case the outcome of the experiment ought to be disregarded, given no weight. Although, I did find potential targets for criticism of the NMCW experimental design I did not find any reasons strong enough to disqualify the NMCW experiment as an experiment inapt, unsound for investigating normative morality, given the features of normative morality entailed within the suggested basic definition provided by Gert and Gert. Finally, I also aimed to selectively discuss some aspects of what it could mean pertaining to the conception of normative morality, according to Gert and Gert, that the thesis was supported. For example, given one interpretation the outcome could be taken to provide support for the non-existence of a normative moral code, but given another be taken to mean that addenda has to be identified and added to the basic conception of normative morality and that such addenda would be such that they would disqualify the NMCW (and its outcome) as a sound and apt thought-experiment to be employed in investigating normative morality. I also attempted to briefly illustrate how the NMCW thought-experiment could be used as a substratum facilitating the identification and clarification of such potential addenda to the basic conception of normative morality, suggested by Gert and Gert, and I also suggest some potential candidate features of the NMCW that further potential specifications added to the basic conception of morality ought to be able to disqualify, exclude as acceptable features of experiments aimed at investigating normative morality. In this way, an unusual, under-represented kind of thought-experiment, “puzzle-piece” when it comes to the large investigative project of employing experiments in order to acquire further insight into normative morality, i.e. “the puzzle”, can regardless of whether it seems to fit or does not seem to fit the “puzzle”, still be employed in such a way as to potentially provide further insight into “the puzzle”. This since even when a “puzzle-piece” does not seem to fit the “puzzle”, “seeing” and understanding how and why could provide us with information about the “puzzle”. / Den normativa moraliska koden anses vara sådan att den gäller universellt för alla eller åtminstone för alla som kan förstå den och reglera sitt beteende i enlighet med den. Alla eller nästan alla vanliga människor tänker och använder sig av sina moraliska koder som om dessa koder vore normativa, normerande genom att det t. ex. för dem helt enkelt verkar finnas ”måsten” som gäller alla och att det ”rakt upp och ner” verkar finnas ”saker” som helt enkelt är rätt och fel, gott och ont. Gert Bernard och Gert Joshua har skrivit en artikel kring ämnet hur man kan definiera moralen med titeln “The Definition of Morality” (sv. ”Moralens Definition”). Författarna föreslår att termen ’normativ moral’ (eller den ’normativa moralen’ i bestämd form) gäller en kod som reglerar hur man bör uppföra sig som givet vissa specificerade förhållanden är sådan att alla rationella personer skulle omfamna och förespråka den. Författarna anser att denna formulering innehåller viktiga och sanna egenskaper hos definitionen kring vad normativ moral är, även om författarna anser att denna basala, grundläggande definition, konception inte är fullständig och att därför vissa ytterligare definitions egenskaper, specifikationer saknas men att alla granskade kandidat-tillägg till denna basala definition som undersöktes inom artikeln verkade vara kontroversiella, enligt författarna. Normativ moral verkar lämplig för att undersökas genom att skapa tankeexperiment inom vilka deltagarna tex kan föreställas stödja, lägga fram eller agera i enlighet med en moralisk kod. Inom detta stora undersökande projekt av normativ moral med hjälp av tankeexperiment så verkade det enligt mig som om det fanns en under-representation av tankeexperiment som uppvisade vissa värdefulla och relevanta egenskaper och jag ansåg att det var ett rättfärdigat projekt att skapa ett tankeexperiment som uppvisade dessa värdefulla och relevanta egenskaper. Ett dylikt experiment kunde anses vara en ovanlig ”pusselbit” som kunde vara ett värdefullt bidrag till slutförandet av ”pusslet”, dvs vad normativ moral är och dess kod. De tre under-representerade egenskaperna var i) en hög grad av lämplighet för att undersöka en stor del av den normativa moraliska koden6eller den kompletta koden och ii) en hög grad av deltagarfrihet, exempelvis avseende deltagarnas handlingar, tankar osv samt iii) en hög grad av förtroende eller rättfärdigande avseende vad deltagarna skulle göra, tänka, känna osv inom tankeexperimentet. Tankeexperimentet, den Normativa Moraliska Kods Workshoppen (NMKW) skapades därför med målsättningen att undersöka den normativa moralen, dess kod samt att experimentet då skulle uppvisa de ovan nämnda egenskaperna. Det är ett tankeexperiment som liknar, ”speglar” en riktig empirisk studie inom vilka deltagarna ges uppgiften att tillsammans stödja och lägga fram den moraliska kod som skulle gälla för dem, reglera deras uppförande och som till en stor del eller fullständigt skulle täcka, innehålla det som de ansåg att deras moraliska koder innehöll. Deltagarna som användes inom min körning av tankeexperimentet var alla nu levande vuxna person som jag ansåg att jag kände väl. Kärn- eller huvudmålsättningen med uppsatsen var att undersöka huruvida det skulle eller inte skulle vara fallet att de flesta eller alla deltagare inom min körning av NMKW tankeexperimentet skulle bestämma sig för att tillsammans lägga fram och stödja en kod, med den valda formuleringen för tesen enligt, det skulle inte vara fallet att de flesta eller alla deltagare skulle lägga fram och stödja koden inom min körning av NMKW experimentet. Som en del av kärnmålsättningen var det att utreda varför tesen var eller inte var stödd samt utreda hur starkt stödet var för utfallet av experimentet, dvs utfallet att en kod lades fram eller inte lades fram. Uppsatsen har även mindre eller bi-målsättningar som strålar ut från uppsatsens huvudmålsättning (se nedan). I min roll som tanke-experimenteraren så rapporterade jag sedan kring vilka händelser som jag föreställde mig, som jag ”såg” uppträda inom tanke-experimentet NMKW då mina valda deltagare tog sig an uppgiften som de ombads att utföra, dvs att tillsammans lägga fram och stödja den kod som skulle komma att gälla dom själva, att appliceras på dom själva. Fyndet var att tesen stöddes och att detta stöd var robust eftersom jag kunde identifiera flera skäl hos deltagarna mot att lägga fram koden medan jag fann mycket litet i form av skäl hos deltagarna för att lägga fram koden. Uppsatsen hade även en del mindre målsättningar att selektivt diskutera några ytterligare relevanta och intressanta spörsmål som strålade ut från uppsatsens huvud-målsättning. Dessa mindre målsättningar kretsade kring att diskutera vissa valda tydliga, centrala egenskaper hos NMKW experimentet samt hur dessa kunde tänkas vara relaterade till experimentets utfall. En sådan egenskap vara den specifika deltagargruppen som användes vid min körning av experimentet. Jag diskuterade till exempel, den potentiella extensionen av utfallet att det inte var fallet att de flesta eller alla deltagare valde att lägga fram koden, ifall deltagargruppen modifierades men fortfarande bestod enbart av nu levande vuxna människor och min värdering var att ett liknande utfall, som vid min körningen av NMKW, verkade troligt för de flesta potentiella grupper av deltagare. Jag ville också diskutera vissa valda tydliga, centrala egenskaper hos NMKW experimentet inom kontexten kring huruvida NMKW experimentet givet dessa egenskaper, borde anses vara ett osunt, olämpligt experiment för att undersöka den normativa moralen, givet Gerts och Gerts konception av denna. Detta, eftersom om detta vore fallet så borde utfallet av experimentet förkastas och inte ges någon vikt. Trots att jag hittade potentiella saker att kritisera hos den experimentella designen hos NMKW så hittade jag inte några tillräckligt starka skäl för att diskvalificera NMKW experimentet som ett olämpligt, osunt experiment för att undersöka den normativa moralen, givet den normativa moralens egenskaper beskrivna, täckta inom Gerts och Gerts föreslagna basala, grundläggande definition av denna. Slutligen så ville jag även selektivt diskutera vissa aspekter kring vad det kunde betyda för konceptionen av den normativa moralen, enligt Gert och Gert, att tesen stöddes. Exempelvis, så givet en tolkning så kunde utfallet ses som ett stöd för icke-existensen hos den normativa moraliska koden, medan givet en annan tolkning så kunde utfallet anses betyda att ytterligare addenda till den basala definitionen av den normativa moralen måste identifieras och adderas till definitionen och att dylika addenda skulle komma att vara sådana att de skulle diskvalificera NMKW experimentet och dess utfall som ett sunt och lämpligt experiment att användas för att studera den normativa moralen, nu med dess extenderade specifikation. Jag försökte sedan att illustrera hur NMKW tankeexperimentet kunde användas som ett substrat för att underlätta identifieringen och förtydligandet av dylika potentiella tillägg till den basala konceptionen av den normativa moralen enligt Gerts och Gerts förslag, och jag föreslog även vissa potentiella kandidat egenskaper hos NMKW experimentet som dylika ytterligare tillägg till den basala konceptionen borde kunna diskvalificera, exkludera som acceptabla egenskaper hos experiment designade för att undersöka den7normativa moralen. På detta sätt så kan en ovanlig, underrepresenterad typ av tankeexperiment, ”pusselbit” när det gäller det stora undersökningsprojektet som använder sig av experiment för att erhålla ytterligare insikter inom den normative moralen, dvs ”pusslet”, oberoende om det verkar passa eller inte passa in i ”pusslet”, ändå användas på ett sådant sätt så att det potentiellt kan leda till ytterligare insikter kring ”pusslet”. Detta eftersom även när en ”pusselbit” inte verkar passa in i ”pusslet” så kan ”seendet”, förtydligandet och förståelsen kring hur och varför, ändå potentiellt förse oss med information om ”pusslet”.

The objective was to examine students’ attitudes versus the concepts of free will and determinism, and to juxtapose these to anxiety and religiosity.An online survey was filled in by 162 Swedish students aged between 18 and 20 in an upper secondary high school. To measure the concepts of free will and determinism the Paulhus & Carey FAD-Plus scale (2011) has been used. Anxiety was measured with two types of the short STAI-index.The factor analysis did not support the idea of an extra division of the original FAD-plus index into the factors ‘free will without moral responsibility’ and the fac-tor ‘moral responsibility’. Some minor sex differences were notices in that females scored higher on fatalistic determinism as well as anxiety. The correlation be-tween free will and scientific determinism were very small negative and not sig-nificant, implying that the two concepts are compatible to at least some respond-ents. The same week correspondence were noticed between scientific determin-ism and moral, showing that the dichotomy between the concepts having low support among students.The traditionally seen opposite concepts of fatalistic and scientific determin-ism were surprisingly positively and significant corresponding.Conclusion of the survey results support the view that the question on free will and determinism is more complex than a simple two way street as shown by Paulhus & Carey (2011) and Nichols & Knobe (2007). Moral responsibility is strongly connected to free will, but is not negatively correlated to determinism showing an interesting paradox in the traditional view of these concepts.

Die Willensfreiheit ist ein zentraler Bestandteil des alltäglichen menschlichen Denkens und bildet eine wichtige Grundlage für Mechanismen unserer Gesellschaft. Trotz dieser zentralen Stellung herrscht unter Philosophen und Psychologen Uneinigkeit darüber, was Willensfreiheit eigentlich bedeutet. Dies wird besonders bei Experimenten zur Untersuchung der Willensfreiheit wie das Libet-Experiment deutlich. In dieser Arbeit wird in drei Surveys empirisch untersucht, ob der Freiheitsbegriff, mit dem die Libet-Experimente operieren, von den Freiheitsintuitionen der Laien gestützt wird, oder ob Laien eher den konträren Freiheitsintuitionen der Philosophen zuneigen. Die Ergebnisse der vorgestellten Untersuchungen zeigen, dass Laien eine von den philosophischen Vorstellungen abweichende Vorstellung von Freiheit haben. / Free will is one of the most crucial concepts in our daily life. It represents one of the most important aspects of daily human behaviour and has crucial importance in societal mechanism. However, despite its importance and long tradition philosophers still disagree on a definition. At the heart of the problem lie diverging intuitions about what is important for the concept of freedom. This is particular obvious in neuroscientific experiment, like the famous Libet-Experiment. Here I investigate in three empirical surveys whether the lay intuitions about freedom match freedom intuitions on which the Libet-experiment are based or rather the classical philosophical intuitions about freedom. For this purpose I adopt the empirical approach of experimental philosophy. The results demonstrate that lay people’s intuitions are pretty much in line with assumption that are made by the Libet-Experiment and contradict common philosophical intuitions about free will.

[pt] A responsabilidade jurídica é, sem dúvidas, um dos institutos mais relevantes do direito, tendo em vista o seu papel de assegurar a coesão social. Dentro da tradição jurídica, os modelos explicativos sobre a atribuição de responsabilidade buscaram prescrever, a partir da uma perspectiva racional, quais os fatores que deveriam ser levados em conta a fim de produzir juízos de responsabilização de forma acurada. Segundo estes, tais juízos deveriam ser produtos de um processo iniciado pela análise causal do evento danoso, seguida da análise das intenções do agente para somente depois assinalar sua culpa e a respectiva punição. No entanto, a tais modelos tradicionais escaparam o fato de que a nossa capacidade de realizar juízos de responsabilidade está inclusa em uma complexa estrutura cognitiva a partir da qual normativizamos o mundo. Recentes descobertas de pesquisadores pertencentes aos campos das ciências cognitivas, da filosofia experimental, da psicologia moral e da psicologia social demonstraram uma inversão na forma como enxergamos o processo de atribuição de responsabilidade. As teorias e pesquisas empíricas formuladas por essas áreas apontam a ingerência da moralidade, das intuições e das emoções em conceitos considerados como neutros pela teoria do direito, como os de causalidade e intencionalidade, e na forma como as pessoas formulam seus juízos de responsabilidade. Neste trabalho busco demonstrar a influência de julgamentos morais e de processos de natureza intuitivo-afetiva sobre a tomada de decisão acerca do instituto da responsabilidade jurídica, com enfoque na responsabilidade penal. Ao final do trabalho, deixo algumas pistas investigativas sobre os impactos dessa influência para o nosso sistema penal. / [en] Legal responsibility is, undoubtedly, one of the most relevant institutes of Law, considering its part in assuring social cohesion. Among legal tradition, the explaining models on the attribution of responsibility intend to assign, from a rational perspective, which factors should be taken in consideration in order to produce accurate responsibility judgments. According to them, such judgments should be products of a process started by the causal analysis of the harmful event, followed by the analysis of the intentions of the agent, to only later assign its blame and respective punishment. However, such traditional models miss the fact that our ability to make responsibility judgments is integrated among a complex cognitive structure from which we normatize the world. Recent discoveries from researchers of the cognitive sciences, experimental philosophy, moral psychology and social psychology fields demonstrate an inversion in the way we see the process of the attribution of responsibility. The theories and empirical researches formulated by these areas point to the interference of morality, intuitions and emotions in concepts considered as neutral by legal theory, such as the concepts of causality and intentionality, and in the way people formulate their responsibility judgments. In this work, I intend to demonstrate the influence of moral judgments and of processes of intuitive and affective nature over the decision-making about the institute of legal responsibility, focusing on criminal responsibility. At the end of this work, I trace some investigative clues about the impact of such influence on our criminal system.

[pt] O direito à felicidade vem, recentemente, ganhando destaque dentro do universo jurídico brasileiro. Sua relevância ganhou uma dimensão ainda maior com a apresentação de duas Propostas de Emenda à Constituição (n.º 19 e 513, de 2010) que tiveram como objetivo inclui-lo no rol de direitos fundamentais. Apesar do arquivamento destas PECs, o posicionamento que vem ganhando destaque entre os juristas brasileiros é que o direito à felicidade está implícito em nosso ordenamento. Entretanto, isso pode não ser benéfico para o ordenamento jurídico, tendo em vista as pesquisas recentes produzidas pela filosofia experimental e pela psicologia comportamental. As primeiras demonstram que o conceito ordinário de felicidade, além de capturar o estado psicológico do agente, possui – diferentemente do esperado – um componente valorativo; enquanto as segundas demonstram que as pessoas, de maneira sistemática, falham em prever ou escolher (caso tenham previsto) aquilo que maximiza sua felicidade. Partindo dessas contribuições, trabalha-se com três hipóteses: (1) O conceito de felicidade, por ser simultaneamente psicológico e valorativo, é bastante variável em virtude da concepção moral de cada sujeito, o que pode trazer resultados negativos para a tomada de decisão judicial; (2) Os diferentes vieses aos quais os indivíduos estão sujeitos no momento de avaliar o que lhes traz mais felicidade podem gerar resultados contrários ao esperado em casos juridicamente relevantes; e (3) Devido às limitações impostas a todos os sujeitos, é prejudicial para o direito a positivação do direito à felicidade. A partir da utilização de uma metodologia tanto bibliográfica quanto experimental, foi possível comprovar as duas primeiras hipóteses da pesquisa, além de terem sido encontrados fortes indícios de que a terceira também está correta. Conclui-se que não vale a pena para o ordenamento jurídico, ao menos no atual cenário jurídico brasileiro, positivar o direito à felicidade às custas da assunção de riscos possivelmente desastrosos para o direito. / [en] The right to happiness has recently gained relevance in Brazil s Constitutional Law debate, mostly because of two Proposed Constitutional Amendments aiming to constitutionalize such right. Even though such amendments did not pass, most legal scholars have adopted the position that the right to happiness is implicit in our legal system. However, this might not be beneficial for the legal system, when taken into consideration the recent finding from the fields of experimental philosophy and behavioral psychology. Research from the former demonstrates that the ordinary concept of happiness, besides capturing the psychological states of an agent, captures – unexpectedly – moral evaluations; while research from the latter demonstrates that people, systematically, fail in predicting and making decisions (if they had predicted) that maximize their happiness. From this point, the research attempts to prove three hypotheses: (1) the concept of happiness, because of its psychological and evaluative components, is highly variable due to the moral conceptions of each subject, what might implicate in negative results for cases based on its grounds; (2) The different types of biases that affect people s decision on what makes them happier might lead to results contrary to the expected in legally relevant cases; (3) Due to the limitations imposed to all people, the insertion of the right to happiness might be extremely harmful to the legal system. With the use of a bibliographical and experimental methodology, it was possible to prove the first two hypotheses presented, as well as to find reliable grounds that point toward the correctness of the third. Therefore, the work concludes that, at least in Brazil s current legal scenario, it is not worth constitutionalizing the right to happiness if this means taking the risks of producing possibly disastrous results for the legal system.
