In this article we argue that self-deception evolved to facilitate interpersonal deception by allowing people to avoid the cues to conscious deception that might reveal deceptive intent. Self-deception has two additional advantages: It eliminates the costly cognitive load that is typically associated with deceiving, and it can minimize retribution if the deception is discovered. Beyond its role in specific acts of deception, self-deceptive self-enhancement also allows people to display more confidence than is warranted, which has a host of social advantages. (...) The question then arises of how the self can be both deceiver and deceived. We propose that this is achieved through dissociations of mental processes, including conscious versus unconscious memories, conscious versus unconscious attitudes, and automatic versus controlled processes. Given the variety of methods for deceiving others, it should come as no surprise that self-deception manifests itself in a number of different psychological processes, and we discuss various types of self-deception. We then discuss the interpersonal versus intrapersonal nature of self-deception before considering the levels of consciousness at which the self can be deceived. Finally, we contrast our evolutionary approach to self-deception with current theories and debates in psychology and consider some of the costs associated with self-deception. (shrink)

Commentators raised 10 major questions with regard to self-deception: Are dual representations necessary? Does self-deception serve intrapersonal goals? What forces shape self-deception? Are there cultural differences in self-deception? What is the self? Does self-deception have costs? How well do people detect deception? Are self-deceivers lying? Do cognitive processes account for seemingly motivational ones? And how is mental illness tied up with self-deception? We address these questions and conclude that none of them compel major modifications to our theory of self-deception, although (...) many commentators provided helpful suggestions and observations.

We treat meaning as nonphysical connection and potential organization. Meaning is a resource that can be used by animals to improve survival and reproduction. The evolu­tion of brains to exploit meaning occurred in two heuristic steps. First, solitary brains developed mental representations of patterns for learning and guiding adaptive action. Second, humankind greatly expanded the usefulness of meaning by using it collectively, such as by deliberately communicating information, creating a body of shared beliefs and understandings, and using meaning to organize (...) social life. The intentional application of meaning to life, as in the quest for a meaningful life, is a later development linked to ways of organizing behavior to maximize future outcomes and relate the individual to societal systems.

Humans have a complex and dynamic mating system, and there is evidence that our modern sexual preferences stem from evolutionary pressures. In the current paper we explore male use of a dual mating strategy: simultaneously pursuing both a long-term relationship (pair-bonding) as well as short-term, extra-pair copulations (variety-seeking). The primary constraint on such sexual pursuits is partner preferences, which can limit male behavior and hence cloud inferences about male preferences. The aim of this study was to investigate heterosexual male mating (...) preferences when largely unconstrained by female partner preferences. In service of this goal, female full-service sex workers (N = 6) were surveyed on the traits and behaviors of their male clients (N = 516) and iterative cluster analysis was used to identify male mating typologies. Two clusters emerged: clients seeking a pair-bonding experience and clients seeking a variety experience. Results also suggested that romantically committed men were more likely to seek a variety experience than a relationship experience. We conclude that men desire both pair-bonding and sexual variety, and that their preference for one might be predicted by fulfilment of the other. These findings have implications for relationships, providing insight into motivations for male infidelity. (shrink)

Von Hippel & Trivers (VH&T) interpret belief in God and belief in strong government as the outcome of an active process of self-deception on a worldwide scale. We propose, instead, that these beliefs might simply be a passive spin-off of efficient cognitive processes.

Von Hippel & Trivers reason that the potential benefits of successfully deceiving others provide a basis for the evolution of self-deception. However, as self-deceptive processes themselves provide considerable adaptive value to an individual, self-deception may have evolved as an end in itself, rather than as the means to an end of improving other-deception.

Cultural variability in self-enhancement is far more pronounced than the authors suggest; the sum of the evidence does not show that East Asians self-enhance in different domains from Westerners. Incorporating this cultural variation suggests a different way of understanding the adaptiveness of self-enhancement: It is adaptive in contexts where positive self-feelings and confidence are valued over relationship harmony, but is maladaptive in contexts where relationship harmony is prioritized.

Von Hippel & Trivers (VH&T) propose that self-deception has evolved to facilitate the deception of others. However, they ignore the subjective moral costs of deception and the crucial issue of credibility in self-deceptive speech. A self-signaling interpretation can account for the ritualistic quality of some self-deceptive affirmations and for the often-noted gap between what self-deceivers say and what they truly believe.

In this essay, we consider helicases, defined as enzymes that use the free energies of binding and hydrolysis of ATP to drive the unwinding of double‐stranded nucleic acids, and ask how they function within, and are “coupled” to, the macromolecular machines of gene expression. To illustrate the principles of the integration of helicases into such machines, we consider the macromolecular complexes that direct and control DNA replication and DNA‐dependent RNA transcription, and use these systems to illustrate how machines centered around (...) coupled polymerase–helicase systems can be regulated by small changes in the interactions of their functional components.

Von Hippel & Trivers suggest that people enhance their own self-views as a means of persuading others to adopt similarly inflated perceptions of them. We question the existence of a pervasive desire for self-enhancement, noting that the evidence the authors cite could reflect self-verification strivings or no motive whatsoever. An identity negotiation framework provides a more tenable approach to social interaction.

Critic, poet and philosopher Friedrich von Schlegel (1772–1829) was a leading figure of German Romanticism. In the two years before his untimely death, he wrote three cycles of lectures intended as part of a larger project to lay the foundations of a new general philosophy. Two of these cycles, 'Philosophie des Lebens' (given in 1827, published 1828) and 'Philosophie des Sprache und des Wortes' (given in December 1828 and published posthumously), are reissued here in an 1847 English translation. The first (...) presents Schlegel's understanding of philosophy as independent of theology or politics, concerned with the 'inner spiritual life' of humankind. The second explores the nature of communication through language and art. Schlegel argues that full human consciousness cannot be restored by Enlightenment science, but only by divine revelation and redemption. He offers no ready-made solutions, but encourages his listeners to develop their own responses to these questions. (shrink)

The Rho GTPases—Rho, Rac and Cdc42—act as molecular switches, cycling between an active GTP‐bound state and an inactive GDP‐bound state, to regulate the actin cytoskeleton. It has recently become apparent that the Rho GTPases can be activated in subcellular zones that appear semi‐stable, yet are dynamically maintained. These Rho GTPase activity zones are associated with a variety of fundamental biological processes including symmetric and asymmetric cytokinesis and cellular wound repair. Here we review the basic features of Rho GTPase activity zones, (...) suggest that these zones represent a fundamental signaling mechanism, and discuss the implications of zone properties from the perspective of both their function and how they are likely to be controlled.

Paralogismen betreffs der Leibnizschen Prädikatlehre werden aufgezeigt und widerlegt. Enthaltensein heißt die Inverse von Ableitung; den zwei Arten von Ableitung, die Leibniz kennt, entsprechen zwei Arten von Enthaltensein. Die beiden Arten von Enthaltensein bieten Leibniz die Möglichkeit zu der logischen und irreduziblen Unterscheidung zwischen notwendigen und bedingten Wahrheiten. Die Unterscheidung zwischen einem Individuum und einer Eigenschaft wird mit mengentheoretischen Methoden und auch mit Hilfe von epistemologischen Begriffen untersucht. Die besondere kategorische Form des Aussagesatzes impliziert, daß es für alle Aussagesätze nur (...) eine einzige Tiefen-Grammatik gibt, welche wesentlich verschiedene Ausdruckweisen von kategorischen Aussagen umfaßt.
