How should we understand the emotional rationality? This first part will explore two models of cognition and analogy strategies, test their intuition about the emotional desire. I distinguish between subjective and objective desire, then presents with a feeling from the "paradigm of drama" export semantics, here our emotional repertoire is acquired all the learned, and our emotions in the form of an object is fixed. It is pretty well in line with the general principles of rationality, especially the lowest reasonable principles. Turned to the second part of this side of reasonable. I will inquire how emotional beliefs, desires, and behaviors contribute to the rationality. I will present a very general biological hypothesis: emotions by controlling highlights the characteristics of perception and reasoning, so that we remove the difficulties due in particular to lead to paralysis; they are being simulated by a simplified perception of information, thus limiting our practice and cognitive choice. How are we to understand emotional or axiological rationality? I pursue analogies with both the cognitive and the strategic models, testing them against intuitions about emotional desires. We distinguish two different classes of desires, the subjective and the objective, and propose that emotions have a semantics that derives from "paradigmatic scenarios", in terms of which our emotional repertoire is learned and the formal objects of our emotions fixed. This fits in well with emerging facts about how our emotional capacities develop, and it can also be squared with the general principles of rationality, particularly minimal rationality. In the second part, I return to the perspective of rationality. I ask how emotions contribute to the rationality of beliefs, desires, and behavior. I proffer a very general biological hypothesis: Emotions spare us the paralysis potentially induced by a particular predicament by controlling the salience of features of perception and reasoning; they temporarily mimic the informational encapsulation of perception and so circumscribe our practical and cognitive options.

Despite the fact that common sense taxes emotions with irrationality, philosophers have, by and large, celebrated their functionality. They are credited with motivating, steadying, shaping or harmonizing our dispositions to act, and with policing norms of social behaviour. It's time to restore emotion's bad rep. To this end, I shall argue that we should expect that some of the “norms” enforced by emotions will be unevenly distributed among the members of our species, and may be dysfunctional at the individual, social, moral, or even species levels. I”ll adduce three considerations in support of that pessimistic view: The fallacy of adaptive fixation, the moral randomness of group selection, and the lack of fit between “natural norms” set up by evolution and those moral and social norms we would like philosophy to justify.

The word "truth" retains, in common use, traces of origins that link it to trust, truth, and truce, connoting ideas of fidelity, loyalty, and authenticity. The word has become, in contemporary philosophy, encased in a web of technicalities, but we know that a true image is a faithful portrait; a true friend a loyal one. In a novel or a poem, too, we have a feel for what is emotionally true, though we are not concerned with the actuality of events and characters depicted. To have emotions is to care about certain things: we can wonder whether those things are really worth caring about. We can wonder whether our passions reflect who we are, and whether they constitute fitting responses to the vicissitudes of life. So there are two aspects to emotional truth: how well an emotion reflects the threats and promises of the world, and how well it reflects our own individual nature. That is the starting point of this book, which looks first at the analogies and disanalogies between strict propositional truth and a looser, "generic" sense of truth. As applied to emotions, generic truth is closer to those original meanings: as in a portrait's fidelity or friend's loyalty. Taken in this sense, the notion of emotional truth opens up large vistas on areas of life essential to our existence as social beings, and to our concerns with beauty, morality, love, death, sex, knowledge, desire, coherence, and happiness. Each of those topics illustrates some facet of the dominant theme of the book: the crucial but often ambivalent role of our emotions in grounding and yet also sometimes undermining our values. Emotions act, in holistic perspective, as ultimate arbiters of values where different and independently justified standards of value compete.

À quoi bon la pensée? Pour de nombreux chercheurs, inspirés par les théories évolutionnistes, la pensée réfléchie est utile à notre espèce. Elle lui confère des avantages importants et contribue à son succès reproductif. Pourtant ses avantages ne sont pas si évidents. La pensée ne figure ni dans les mécanismes de l'évolution qui ont façonné la vie, ni parmi les procédés dont se servent la plupart des organismes pour s'y maintenir. Dans Évolution et rationalité, Ronald de Sousa montre que, pour comprendre les avantages de la pensée réfléchie, il faut changer nos présupposés relatifs à la rationalité et reconnaître la multiplicité de ses dimensions. La rationalité ne nous sert pas seulement à avoir des croyances vraies et à agir de manière efficace dans un environnement changeant. Elle nous aide à gérer nos plaisirs et nos peines dans le temps et nous permet d'envisager des situations qui n'existent pas. En général, le statut de la rationalité comme ensemble de capacités ayant évolué dans le cours de l'histoire naturelle de notre espèce, passant des tropismes aux désirs et de la détection à la représentation, n'a pas été pris suffisamment au sérieux. Suivre ce processus d'évolution de la rationalité permet de comprendre comment elle est devenue une norme, mais aussi pourquoi il lui arrive aussi souvent d'échouer. Ronald de Sousa a profondément modifié nos façons de concevoir les émotions. Avec Évolution et rationalité, il pourrait avoir une influence aussi décisive sur nos façons de concevoir la rationalité.
