Anorexia nervosa remains an enigma among Western cultures. Various causal explanations have been offered, encompassing biological, psychological, and sociocultural models. These explanations, however, focus on the immediate or proximal mechanisms of causation. A more thorough understanding of anorexia nervosa can be achieved by understanding the relationship between these factors and ultimate causation, the level of explanation which deals with individual reproductive fitness. This paper reviews the biological, psychological, sociocultural, and evolutionary models and indicates a necessary synthesis between proximate and (...) ultimate levels of causation in examining the anorexia nervosa puzzle.

This paper investigates the implicative conditional, a connective intended to describe the logical behavior of an empirically defined class of natural language conditionals, also named implicative conditionals, which excludes concessive and some other conditionals. The implicative conditional strengthens the strict conditional with the possibility of the antecedent and of the contradictory of the consequent. $${p\Rightarrow q}$$ p ⇒ q is thus defined as $${\lnot } \Diamond {(p \wedge \lnot q) \wedge } \Diamond {p \wedge } \Diamond {\lnot q}$$ ¬ ◊ (...) ( p ∧ ¬ q ) ∧ ◊ p ∧ ◊ ¬ q. We explore the logical properties of this conditional in a reflexive normal Kripke semantics, provide an axiomatic system and prove it to be sound and complete for our semantics. The implicative conditional validates transitivity and contraposition, which we take to be integral parts of reasoning and communication. But it only validates restricted versions of strengthening the antecedent, right weakening, simplification, and rational monotonicity. Apparent counterexamples to some of these properties are explained as due to contextual factors. Finally, the implicative conditional avoids the paradoxes of material and strict implication, and validates some connexive principles such as Aristotle’s theses and weak Boethius’ thesis, as well as some highly entrenched principles of conditionals, such as conjunction of consequents, disjunction of antecedents, modus ponens, cautious monotonicity and cut.

This essay examines the reception of Ivan Pavlov’s work on conditioned reflexes in early to mid-twentieth century Britain. Recent work on the political interpretation of biology has shown that the nineteenth-century strategy of “making socialists” was undermined by August Weismann’s attacks on the inheritance of acquired characters. I argue that Pavlov’s research reinvigorated socialist hopes of transforming society and the people in it. I highlight the work of Pavlov’s interpreters, notably the scientific journalist J. G. Crowther, the biologist Lancelot (...) Hogben, and the science writer H. G. Wells, who made Pavlov’s work accessible to a British audience and embraced the socialist implications of his research – especially the idea that people could be persuaded to become socialists through science writing for a nonspecialist audience and through use of a simplified language such as Basic English. They saw, in the followers of National Socialism, how Pavlovian conditioning could create a national movement, and believed that this could be used for their own more democratic form of socialism. In the final part of the essay, I suggest that this broad socio-cultural movement to reshape humanity proved controversial, especially in the post-war period and in light of Soviet use of brainwashing. The likes of Aldous Huxley and F. A. Hayek feared that conditioning could only lead to totalitarianism, while the historian E. P. Thompson put forward a socialist humanism that left room for human agency. (shrink)

How is time transformed when signs appear? In the sign system of the conditioned reflex, the sign (conditioned stimulus) reverses, changes the direction of time, and overcomes its unidirectionality and irreversibility. In a sense, there is a “return” to the past in the form of the future when the sign is introduced. The sign serves as a “Time machine” of sorts. The mechanism of time transformation is possible because a mirror is embedded inside the sign, the surface (...) of which represents the psychological present time. When past experience meets that surface in the present, it may be reflected in the form of a future event. In the course of reflection, time changes its direction: if earlier time flowed from the event (the cause), it subsequently flows to other events (the purpose). Previously inaccessible past experience is now projected into the present, “comes to life” in it and is transformed into the future. In humans, unlike in animals, signs of the second order appear. Inside the signs of the second order, a mirror is built in, and the experience of the past as a subject is reflected in the future form as an object. An individual has the opportunity to consider oneself externally as an object. It goes beyond the subjective form. Thus, secondary signs once again change time direction. Due to this phenomenon, time becomes doubly reversible: first it turns around in a conditioned stimulus, and then in a secondary sign. (shrink)

From its earliest beginnings, American conditioning research using human subjects had to deal with the possibility that subjects might voluntarily control the reaction that the experimenter attempts to condition, with the result that voluntary control contaminates the study of conditioning in humans. A preliminary solution to the problem was achieved around 1940, ending the time frame of this survey. This article provides an historical survey of the conceptual background of the opposition of volition and reflexes; describes manifestations of the problem (...) in conditioning research; and critically examines earlier efforts to solve the problem as well as the presumptive solution that disposed of the issue by 1940. Lessons from this story are adduced. (shrink)

The operation of voluntary processes can contaminate the study of Pavlovian conditioned responses in humans. The problem of voluntary control had apparently been solved by about 1940, particularly in human eyelid conditioning. Nonetheless, the problem returned in the early 1950s, calling forth a variety of methodological procedures for removing voluntary responses and/or voluntary-responding subjects from eyelid-conditioning data. During the 1960s, disagreement arose regarding the efficiency and comparability of alternative data-correction procedures; the rationale for data-correction; and whether, and under what (...) experimental conditions, eyelid-conditioning data ought to be corrected for voluntary responding. Circumstances that supported voluntary-response methodology are described, and points at which the methodology conflicted with the technical background of Pavlovian conditioning are noted. A diagnosis is offered for the failure, between 1950 and 1980, to solve again the problem of volition. (shrink)

This essay develops the core intuition that we need to transform the objective condition of globalization into a reflexive consciousness of a cosmopolitan connectedness. We require a cosmopolitan self-understanding that allows us to respond in a normatively guided way to objective processes that undermine the usual venues of political will formation. Since our global connectedness in terms of economic and political integration is ongoing and seemingly inevitable, we need a similarly inclusive and global approach to critically respond to the challenge (...) of these unconstrained forces. The proposal is to develop a dialogical cosmopolitanism which is not based on a new meta-level of abstract universal norms, but grounded in agentive capabilities. Hermeneutic capabilities which comprise contextual perspective-taking are introduced, developing shared yet fallible norms, and critically reflecting on the power relations involved. These agent-based capabilities would allow the situated agents themselves to understand the objective forces that define current globalization and provide normative resources for a different, cosmopolitan globalization.

In a previous paper it was suggested that specific concepts are needed in the psychological sciences and the basic mental triad was described as a useful tool to further our understanding of mentation. It was stated that the sensori-motor reflex principle cannot describe and explain mental phenomena, because the reflex is basically a mechanistic occurrence, while mental phenomena differ in essence from mechanisms. Since conditioned reflexes can be conceived as sensori-motor reflexes with another, non-mechanistic factor superimposed, similarities (...) and contrasts between reflexes and conditioned reflexes were taken as the material from which one can develop new thoughts about mentation. Reflex shutting of the eyelid, caused by direct contact between cornea and a small, invisible foreign body was compared with and contrasted to shutting the eye before a large, visible object thrusting toward the eye. It was shown that reflexes occur in response to a stimulus after the stimulus has been applied, while conditioned reflexes seem to anticipate the stimulus. This was taken as evidence that conditioned reflexes have a protensive character, have a relationship to the future, which sensori-motor reflexes lack. This difference in time relationship was developed into the statement that the difference between mechanisms and mental phenomena lies in their different relationship to the future. The need for specific concepts to describe mental phenomena stems from the inability of the reflex principle to deal with the protensive tendency of mental phenomena and to fill this need the concept of the basic mental triad was offered. This principle consists of three interdependent, interwoven phases: the triad connects with the past through condensation of some of the subject's past experience into a vaguely formed conglomerate; it connects with the future by projecting the condensed past into the future; the central phase of the triad is the act within the present instant, where a synthesis of past, present and future is accomplished.
