L’amitié et l’amour romantique sont, de par leur nature, des relations exclusives. Cet article suggère que l’on peut mieux comprendre la nature de l’exclusivité dont il est question en comprenant l’erreur au coeur de la vision du raisonnement pratique que je nomme « le point de vue englobant » . Selon le PVE, pour que le raisonnement pratique soit rationnel, il doit s’agir d’un processus ayant pour but de choisir la meilleure alternative possible à partir d’une perspective qui est aussi détachée et objective que possible. Quoique cette vision cherche à être neutre à l’égard des porteurs de valeurs, elle incorpore en fait un biais contre les porteurs de valeurs qui ne peuvent être appréciés qu’à partir d’une perspective qui n’est pas détachée - qui ne peuvent être appréciés, par exemple, que par les agents qui sont engagés à long terme envers les valeurs en question. Dans le contexte des relations personnelles, de tels engagements tendent à donner naissance à la sorte d’exclusivité qui caractérise l’amitié et l’amour romantique ; ils empêchent l’agent d’être impartial entre les besoins, les intérêts, etc. de la personne qui lui est chère, d’une part, et ceux des autres, d’autre part. Je suggère que dans de tels contextes les besoins et les revendications des autres personnes peuvent être réduites au silence, de la même manière que, comme le suggère John McDowell, les tentations de l’immoralité sont, pour l’agent vertueux, réduites au silence.

Summary: Recent research on the evolution of language and verbal displays (e.g., Miller, 1999, 2000a, 2000b, 2002) indicated that language is not only the result of natural selection but serves as a sexually-selected fitness indicator that is an adaptation showing an individual’s suitability as a reproductive mate. Thus, language could be placed within the framework of concepts such as the handicap principle (Zahavi, 1975). There are several reasons for this position: Many linguistic traits are highly heritable (Stromswold, 2001, 2005), while naturally-selected traits are only marginally heritable (Miller, 2000a); men are more prone to verbal displays than women, who in turn judge the displays (Dunbar, 1996; Locke & Bogin, 2006; Lange, in press; Miller, 2000a; Rosenberg & Tunney, 2008); verbal proficiency universally raises especially male status (Brown, 1991); many linguistic features are handicaps (Miller, 2000a) in the Zahavian sense; most literature is produced by men at reproduction-relevant age (Miller, 1999). However, neither an experimental study investigating the causal relation between verbal proficiency and attractiveness, nor a study showing a correlation between markers of literary and mating success existed. In the current studies, it was aimed to fill these gaps. In the first one, I conducted a laboratory experiment. Videos in which an actor and an actress performed verbal self-presentations were the stimuli for counter-sex participants. Content was always alike, but the videos differed on three levels of verbal proficiency. Predictions were, among others, that (1) verbal proficiency increases mate value, but that (2) this applies more to male than to female mate value due to assumed past sex-different selection pressures causing women to be very demanding in mate choice (Trivers, 1972). After running a two-factorial analysis of variance with the variables sex and verbal proficiency as factors, the first hypothesis was supported with high effect size. For the second hypothesis, there was only a trend going in the predicted direction. Furthermore, it became evident that verbal proficiency affects long-term more than short-term mate value. In the second study, verbal proficiency as a menstrual cycle-dependent mate choice criterion was investigated. Basically the same materials as in the former study were used with only marginal changes in the used questionnaire. The hypothesis was that fertile women rate high verbal proficiency in men higher than non-fertile women because of verbal proficiency being a potential indicator of “good genes”. However, no significant result could be obtained in support of the hypothesis in the current study. In the third study, the hypotheses were: (1) most literature is produced by men at reproduction-relevant age. (2) The more works of high literary quality a male writer produces, the more mates and children he has. (3) Lyricists have higher mating success than non-lyric writers because of poetic language being a larger handicap than other forms of language. (4) Writing literature increases a man’s status insofar that his offspring shows a significantly higher male-to-female sex ratio than in the general population, as the Trivers-Willard hypothesis (Trivers & Willard, 1973) applied to literature predicts. In order to test these hypotheses, two famous literary canons were chosen. Extensive biographical research was conducted on the writers’ mating successes. The first hypothesis was confirmed; the second one, controlling for life age, only for number of mates but not entirely regarding number of children. The latter finding was discussed with respect to, among others, the availability of effective contraception especially in the 20th century. The third hypothesis was not satisfactorily supported. The fourth hypothesis was partially supported. For the 20th century part of the German list, the secondary sex ratio differed with high statistical significance from the ratio assumed to be valid for a general population.
