This chapter offers a general outline of Schopenhauer’s peculiarly named concept of the 'acquired character’ and explains its basic function in his ethical thought. For Schopenhauer, a person of acquired character is someone who knows the ways of acting (Handlungsweise) that are most expressive of their individuality and who allows that self-knowledge to structure their practical and emotional life. In keeping with certain elements of his psychological determinism, acquired character is not the acquisition of a ‘new’ character; (...) rather, it is the acquisition of self-knowledge of one’s essentially fixed empirical character. It is part of the argument of this chapter that by introducing the acquired character into his reflections on human action and agency Schopenhauer weaves a certain view of individual flourishing (eudaimonia) into his ethics. There are two central ingredients of Schopenhauer’s conception of eudaimonia, and both are linked to the acquired character. The first is self-knowledge; the second is a sense of personal autonomy that follows in the wake of the first. The chapter ends with a brief attempt to connect Schopenhauer’s concept of acquired character to contemporary debates in ethics concerning autonomy, practical identity, and what some call the ‘normative significance of self’.

Character and culture describe man both as an active and a passive agent in life. It is by being fashioned by culture that man cultivates character and by the use of this character so acquired that he develops and upgrades his culture; for culture is dynamic, that is elastic; as such there is need for eternal vigilance on the part of man to see his culture evolve and become better at every point in time. This can come about either (...) spontaneously or through an agency; it is the duty of an agency to act upon what is given, required to produce a good result, in our instance to act on Igbo-African family values. This entails a dialogue of man and his milieu, for character grows form a healthy and salutary agent, so knowledge of, belief in and application of values is indeed a precondition. (shrink)

The probing readings of Putting On Virtue offered by Sheryl Overmyer, Darlene Weaver, and James Foster provide a welcome opportunity for further reflection on key questions: Was Aquinas really concerned with the status of pagan virtues? Can we properly understand a thinker whose driving questions are not the same as our own without taking up a stance of pure deference? Can an inquiry into hyper-Augustinian anxiety over acquired virtue assist us in arriving at an account of positive self-regard? Can (...) an account that stresses the graced character of all virtue formation be coherent? And can it do justice to the ways in which Christians reached for accounts of infused virtue precisely in order to affirm how grace overcomes the ways in which fortune hounds acquired virtue? I respond affirmatively to all of the above. (shrink)

Most theories about virtue cultivation fall under the general umbrella of the role model approach, according to which virtue is acquired by emulating role models, and where those role models are usually conceived of as superior in some relevant respect to the learners. I argue that although we need role models to cultivate virtue, we also need good and close relationships with people who are not our superiors. The overemphasis on role models is misguided and misleading, and a good (...) antidote draws on the Aristotelian concept of character friendship. Character friendship constitutes a unique form of experience in which we share a substantial way of seeing with a close other; facilitates a unique form of knowledge, the knowledge of a particular person ; develops other emotions important for virtue cultivation besides admiration, such as love, shame, trust, and hope; and is a praxis in which cooperative interactions and discussions function as a bridge between habituation of virtue at home and the public life. Character friendship provides necessary elements for human cultivation of virtue that the sole experience of having a role model does not. (shrink)

Most theories of moral agency, whether philosophical or psychological in emphasis, tend to conceive of either character or outlook as fundamental. That is, they take moral agency to consist either in the possession of certain traits of character or virtues or else in the ability to comprehend and act according to certain types of rules or standards. This dissertation is an attempt to reconcile the two conceptions of moral agency by giving a developmental account of the way in which character (...) and outlook begin in unity and gradually diverge as the moral agent matures. Key to this account are extended discussions of the psychological theories of moral development given by Lawrence Kohlberg, Carol Gilligan, and John Rawls. Although these theories together provide a satisfactory explanation of how outlook develops after a person has acquired a basic set of moral concepts, they do not satisfactorily explain the initial formation of moral concepts. That failure results in an impoverished conception of the mature moral agent, a conception which fails to appreciate the richness and variety of moral life, especially in regard to the types of motivational influence to which the mature moral agent is susceptible. Nonetheless, I maintain that these theories of moral development are satisfactory insofar as they show how a person's early moral concepts are partially displaced by later, more sophisticated concepts which make up a mature agent's outlook, but they are displaced only as far as the justification of behavior is concerned; the more primitive concepts, which initially constitute an agent's character and outlook together, continue to have a significant motivational influence that is essential for mature moral agency.

In light of the dramatic growth of Chinese learners worldwide and a need for cross-linguistic research on Chinese literacy development, this study drew upon theories of visual complexity effect (Su & Samuels, 2010) and dual-coding processing (Sadoski & Paivio, 2013) and investigated a) the effects of character properties (i.e., visual complexity and radical presence) on character acquisition and b) the relationship between individual learner differences in radical awareness and character acquisition. Participants included adolescent English-speaking beginning learners of Chinese in the (...) U.S. Following Kuo et al. (2014), a novel character acquisition task was used to investigate the process of acquiring the meaning of new characters. Results showed that a) characters with radicals and with less visual complexity were easier to acquire than characters without radicals and with greater visual complexity; and b) individual differences in radical awareness were associated with the acquisition of all types of characters, but the association was more pronounced with the acquisition of characters with radicals. Theoretical and practical implications of the findings were discussed. (shrink)

The argument of this paper is that we should think of the extension of cognitive abilities and cognitive character in integrationist terms. Cognitive abilities are extended by acquired practices of creating and manipulating information that is stored in a publicly accessible environment. I call these cognitive practices (2007). In contrast to Pritchard (2010) I argue that such processes are integrated into our cognitive characters rather than artefacts; such as notebooks. There are two routes to cognitive extension that I (...) contrast in the paper, the first I call artefact extension which is the now classic position of the causal coupling of an agent with an artefact. This approach needs to overcome the objection from cognitive outsourcing: that we simply get an artefact or tool to do the cognitive processing for us without extending our cognitive abilities. Enculturated cognition, by contrast, does not claim that artefacts themselves extend our cognitive abilities, but rather that the acquired practices for manipulating artefacts and the information stored in them extend our cognitive abilities (by augmenting and transforming them). In the rest of the paper I provide a series of arguments and cases which demonstrate that an enculturated approach works better for both epistemic and cognitive cases of the extension of ability and character.

The author engages a question raised about theories of nonexistent objects. The question concerns the way names of fictional characters, when analyzed as names which denote nonexistent objects, acquire their denotations. Since nonexistent objects cannot causally interact with existent objects, it is thought that we cannot appeal to a `dubbing' or a `baptism'. The question is, therefore, what is the starting point of the chain? The answer is that storytellings are to be thought of as extended baptisms, and the (...) details of this response receive attention in the paper. Once the storytelling is complete, and the characters have been baptized, a priori metaphysical principles linking the storytelling with the realm of nonexistent objects provide the referential, non-causal connection between the names used in the storytelling and the objects denoted by such names.

Determinants of synesthetic color choice for the Japanese logographic script, Kanji, were studied. The study investigated how synesthetic colors for Kanji characters, which are usually acquired later in life than other types of graphemes in Japanese language , are influenced by linguistic properties such as phonology, orthography, and meaning. Of central interest was a hypothesized generalization process from synesthetic colors for graphemes, learned prior to acquisition of Kanji, to Kanji characters learned later. Results revealed that color choices (...) for Kanji characters depend on meaning and phonological information. Some results suggested that colors are generalized from Hiragana characters and Arabic digits to Kanji characters via phonology and meaning, respectively. Little influence of orthographic information was observed. The findings and approach of this study contributes to a clarification of the mechanism underlying grapheme-color synesthesia, especially in terms of its relationship to normal language processing.

The opening words of the second book of Aristotle’s Nicomachean Ethics are as familiar as any in his corpus: Excellence of character results from habituation [ethos]—which is in fact the source of the name it has acquired [êthikê], the word for ‘character-trait’ [êthos] being a slight variation of that for ‘habituation’ [ethos]. This makes it quite clear that none of the excellences of character [êthikê aretê] comes about in us by nature; for no natural way of being is changed (...) through habituation [ethizetai]. Equally familiar, unfortunately, is the characterization of Aristotle’s notion of character formation as a form of habituation by means of the repetition of actions which results in a “habit” in the same way that a weight lifter produces muscles through the repetition of exertions. As a 19th century commentator remarked on the passage above, “[insert Grant].” From a Socratic perspective, such a view of becoming good seems hopelessly rigid and unconnected to the intellectual development which knowledge of the good requires. Habit and habituation in Aristotle seem eminently familiar and eminently unphilosophical. Such a view would be mistaken on at least three counts. First, the notion of character formation (to use the broadest possible term for the phenomenon of habituation) in Aristotle is significantly more complicated than the notion that through habituation one develops good habits which are what we mean by ethical virtue. Although character formation includes the development of proper emotional responses, such as taking pleasure in what is fine and being repulsed by what is shameful, it is equally concerned with cognitive development independent of the intellectual virtues. Second, although Aristotle’s terms for “ethics” (êthica), character-trait (êthos), and habituation (ethos, ethismos, or ethizetai) are linguistically and conceptually interrelated, his notion of “ethical state” (hexis) is both linguistically and conceptually quite distinct from the notion of “habit,” at least as we use that term today. As one Aristotle translator has put it, “A hexis is not only not the same thing as a habit, but is almost exactly its opposite.” For Aristotle, a hexis is a dynamic equilibrium which, although always productive of virtuous actions, is nonetheless the basis for being virtuous in varied circumstances. Thirdly, once Aristotle’s notion of a character state is retrieved from its false association with “habit” and repetitive habituation, one sees that its apparent divorce from practical reason is more a fixture of Aristotle’s analytical method and its connotations of inflexibility or fixedness are in fact antithetical to Aristotle’s description of ethical virtue. Rather than view ethical “character” in its Greek etymological sense as an indelibly fixed or engraved mark or stamp (charactêr) upon one’s soul, Aristotle’s notion of ethical character (êthos) or virtue (aretê) captures the notion of a virtuoso who is responsive in an excellent fashion to what reason perceives in particular and changing circumstances.

Scholars studying the history of heredity suggest that during the 19th-century biologists and anthropologists viewed characteristics as a collection of blended qualities passed on from the parents. Many argued that those characteristics could be very much affected by environmental circumstances, which scholars call the inheritance of acquired characteristics or "soft" heredity. According to these accounts, Gregor Mendel reconceived heredity - seeing distinct hereditary units that remain unchanged by the environment. This resulted in particular traits that breed true in succeeding (...) generations, or "hard" heredity. The author argues that polygenist anthropology (an argument that humanity consisted of many species) and anthropometry in general should be seen as a hardening of heredity. Using a debate between Philadelphia anthropologist and physician, Samuel G. Morton, and Charleston naturalist and reverend, John Bachman, as a springboard, the author contends that polygenist anthropologists hardened heredity by conceiving of durable traits that might reappear even after a race has been eliminated. Polygenists saw anthropometry (the measurement of humans) as one method of quantifying hereditary qualities. These statistical ranges were ostensibly characteristics that bred true and that defined racial groups. Further, Morton's interest in hybridity and racial mixing demonstrates that the polygenists focused as much on the transmission and recognition of "amalgamations" of characters as they did on racial categories themselves. The author suggests that seeing race science as the study of heritable, statistical characteristics rather than broad categories helps explain why "race" is such a persistent cultural phenomenon.

Indirect situationist critiques of virtue ethics grant that virtue exists and is possible to acquire, but contend that given the low probability of success in acquiring it, a person genuinely interested in behaving as morally as possible would do better to rely on situationist strategies - or, in other words, strategies of environmental or ecological engineering or control. In this paper, I develop a partial answer to this critique drawn from work in early Confucian ethics and in contemporary philosophy and (...) psychology. From early Confucian ethics, I lean on the concept of li, or ritual. Ritual represents both a set of situational manipulations that are especially effective at directly producing moral behavior and at indirectly cultivating virtue over time, and also a virtue that consists of facility with and expertise in these situational manipulations. Appealing to the particular example of social power, I then argue that one is justified in attempting to acquire virtue if one knows that one will frequently encounter circumstances in which purely situationist strategies lose effectiveness, if these circumstances also carry moral urgency: the risk of great harm or opportunity for great benefit to others is high, and if utilizing the potent combination of situationist strategies and virtue envisioned by the early Confucians as ritual is possible.

Human persons can act with libertarian freedom in heaven according to one prominent view, because they have freely acquired perfect virtue in their pre-heavenly lives such that acting rightly in heaven is volitionally necessary. But since the character of human persons is not perfect at death, how is their character perfected? On the unilateral model, God alone completes the perfection of their character, and, on the cooperative model, God continues to work with them in purgatory to perfect their own (...) character. I argue that although both models can make sense of all human persons enjoying free will in heaven on various assumptions, the cooperative model allows all human persons in heaven to enjoy a greater degree of freedom. This consideration about the degree of heavenly freedom provides a reason for God to implement the cooperative model. (shrink)

Aquinas is often presented as following Aristotle's "Nicomachean Ethics" when treating moral virtue. Less often do philosophers consider that Aquinas's conception of the highest good and its relation to the functional character of human activity led him to break with Aristotle by replicating each of the acquired moral virtues on an infused level. The author suggests that we can discern reasons for this move by examining Aquinas's commentary on the "Sententiae" of Peter the Lombard and the "Summa theologiae" within (...) their historical context. The author's thesis is that Dominican pastoral and intellectual concerns led Aquinas to argue that moral virtue must necessarily be ordered toward the highest good. Understanding this purpose helps to explain his presentation of moral virtue and its implications for standard philosophical interpretations of his work. (shrink)

Critics of Laudan's normative naturalism have questioned whether methodological rules can be regarded as empirical hypotheses about relations between means and ends.

I The existence of the legal profession is something most lawyers take for granted. Lawyers of course do many different things, and lead different sorts of lives, but those who make their living in the law tend to assume, without much reflection, that they have a bond or association of some sort with others who do the same and believe they share something important in common with them. It is not at all clear, however, what this common element is, and (...) the great diversity of tasks that lawyers perform – representing litigants, counseling clients, advising legislators, administering government programs, and deciding cases – can easily make one doubt whether the search for a link leads to anything but empty generalities. One may, of course, conclude that the main law jobs, as Karl Llewellyn called them, have nothing important in common, and that the legal profession is only a name for a disconnected collection of pursuits with no substance or reality of its own. This is not, however, a very satisfying view, to lawyers at least, and is likely to provoke the quick reply that what lawyers share in common is after all quite easy to discern. All lawyers, regardless of the nature of their work, possess a general knowledge of the law which they have acquired through a specialized program of instruction; laypersons lack such knowledge and it is this, one might argue, which marks the line between those who are lawyers and those who are not and, thus, defines the scope and nature of the profession.

Contemporary proponents of modern Buddhism argue that the Buddha’s teaching, in contrast to later Buddhist-inspired philosophies and folklore, is of a fundamentally therapeutic or experiential character. In response, other scholars have objected that this amounts to an inadequate protestantization that neglects soteriology and the broader religious or cultural context. In this paper, by critically engaging with therapeutic readings (as proposed by Stephen Batchelor) and experiential readings (as proposed by Alan Wallace and D. T. Suzuki) and by drawing from a few (...) significant early Pāli discourses, I reconstruct the Buddha’s teaching in a way that, like many modern interpretations, does not rely on belief in magical powers and spirits but that, unlike many modern interpretations, does not exhaust itself in mere therapeutics or experiential knowledge. My interpretation is grounded in a notion of negative self-knowledge that takes two distinct forms. On the one hand, there is the self-knowledge of not-self as an antecedent recognition of the possibility of awakening that defines the Buddhist seeker. On the other hand, there is the acquired self-knowledge of not-self of the awakened. The latter—that is, the completed insight into what we are not—is not just one experience among others but the transformation of any possible experience. Thus, the Buddha speaks to us of his self-knowledge that exceeds experiential knowledge. This imbalance between the Buddha and his real or potential interlocutors explains why his teaching remains inaccessible to many, in spite of modern attempts to rationalize it. (shrink)

Thomas Aquinas situates virtues of character in the noncognitive appetite. He also claims that virtues of character provide the ends in practical matters. Since providing proper ends seems to be a cognitive act, it is unclear how virtues of character, qua perfections of the noncognitive appetite, provide ends. After criticizing three approaches to this interpretive challenge, we suggest that Aquinas provides us with a theory of practical identity. We argue that that on Aquinas's view a practical identity is constituted both (...) by a virtuous disposition in the appetitive power and by a rational commitment to proximate ends, a rational commitment that results from acquiring the virtuous disposition. With this account of practical identity in mind, we explain how Aquinas can consistently claim that virtues, qua perfections of the appetite, provide ends. (shrink)

American society was transformed by the expansion of capital Westward and the explosion in opportunities for land-grabbing and agricultural and industrial investment. F.J.

Schmitt indicated the significance of a ‘vertical’ frontier in challenging social conventions and this constitutes a counterpoint to the ‘horizontal’ (...) frontier developed in the frontier thesis of Turner. The importance of the occasion and personality in developing the American way of life is presented by an examination of the vaudeville and celebrity traditions in American entertainment. (shrink)

If there was a new wonder drug on the market that got kids to behave better, improve their grades, feel happier, and avoid risky behaviors, many parents around the world would be willing to empty their bank accounts to acquire it. Amazingly, such a product actually does exist. It’s not regulated by the FDA, it has no ill side-effects, and it’s absolutely free and avail­able to anyone at any time. This miracle cure is gratitude. Over the past decade, science has (...) shown that gratitude is one of the most valuable and important emotions we possess, and it is a virtue that anyone can cultivate. In fact, researchers have developed many different methods people can use to foster an attitude of gratitude, and the science shows that many of them really work. In _Making Grateful Kids, _two of the leading authorities on gratitude among young people, Jeffrey J. Froh and Giacomo Bono, introduce their latest and most compelling research, announce groundbreaking findings, and share real-life stories from adults and youth to show parents, teachers, mentors, and kids themselves how to achieve greater life satisfaction through gratitude. Most importantly perhaps, they expand on this groundbreaking research to offer practical and effec­tive common-sense plans that can be used in day-to-day interactions between kids and adults to enhance success and wellbeing. Their unique, scientifically-based approach for producing grateful youth works whether these kids are very young ele­mentary school students or troubled teenagers. Not only does the purposeful practice of gratitude increase their happiness, but the research indicates that grateful kids also report more self-discipline, fulfilling relationships, and engagement with their schools and communities when compared to their less grateful counterparts. After reading _Making Grateful Kids_, parents, teachers, and anyone who works with youth will be able to connect more mean­ingfully with kids so that all parties can focus on the things that matter most and, in turn, create a more cooperative and thriving society.

In the Phaedrus scientific psychology is an integral part of Plato's outline of scientific rhetoric.

This article explores the seemingly paradoxical thesis that the society depicted in Aldous Huxley's Brave New World is anti-utopian because it seeks to eliminate suffering. As Huxley suggests in The Perennial Philosophy and other works, suffering is a necessary condition for acquiring knowledge of God, and such knowledge constitutes genuine happiness. Since the Brave New World seeks to eliminate the necessary condition for its citizens' happiness, it is, therefore, anti-utopian.

August Weismann is famous for having argued against the inheritance of acquired characters. However, an analysis of his work indicates that Weismann always held that changes in external conditions, acting during development, were the necessary causes of variation in the hereditary material. For much of his career he held that acquired germ-plasm variation was inherited. An irony, which is in tension with much of the standard twentieth-century history of biology, thus exists – Weismann was not a Weismannian. (...) I distinguish three claims regarding the germ-plasm: (1) its continuity, (2) its morphological sequestration, and (3) its variational sequestration. With respect to changes in Weismann’s views on the cause of variation, I divide his career into four stages. For each stage I analyze his beliefs on the relative importance of changes in external conditions and sexual reproduction as causes of variation in the hereditary material. Weismann believed, and Weismannism denies, that variation, heredity, and development were deeply intertwined processes. This article is part of a larger project comparing commitments regarding variation during the latter half of the nineteenth century. (shrink)

Adaptive evolution is usually assumed to be directed by selective processes, development by instructive processes; evolution involves random genetic changes, development involves induced epigenetic changes. However, these distinctions are no longer unequivocal.

Incorporating the effects of instructive processes into evolutionary thinking alters ideas about the way environmental changes lead to evolutionary change, and about the interplay (...) between genetic and epigenetic systems.

This paper examines the roles that self-knowledge and reflection play in Schopenhauer’s view of agency. Focusing in particular on the discussion of the acquired character, his cognitive theory of motivation, and the idea of intellectual freedom, I argue that we find two conceptions of rational agency in Schopenhauer. The ‘minimal’ conception sees rational agency primarily as a kind of reflective motivation, whereas the ‘maximal’ or ‘robust’ conception sees rational agency as involving a kind of reflective self-organization. Furthermore, I argue (...) that rational self-organization and acquired character go hand-in-hand: it is only in virtue of achieving the latter that one achieves the former. Although some worry that the discussion of acquired character does not sit well with Schopenhauer’s broader determinist theory of action, the reading offered here aims to demonstrate that the two are reconcilable.

When philosophers defend epiphenomenalist doctrines, they often do so by way of a priori arguments. Here we suggest an empirical approach that is modeled on August Weismann’s experimental arguments against the inheritance of acquired characters. This conception of how epiphenomenalism ought to be developed helps clarify some mistakes in two recent epiphenomenalist positions – Jaegwon Kim’s (1993) arguments against mental causation, and the arguments developed by Walsh (2000), Walsh, Lewens, and Ariew (2002), and Matthen and Ariew (2002) that (...) natural selection and drift are not causes of evolution. A manipulationist account of causation (Woodward 2003) leads naturally to an account of how macro- and micro-causation are related and to an understanding of how epiphenomenalism at different levels of organization should be understood.

Galton greeted Darwin's theory of pangenesis with enthusiasm, and tried to test the assumption that the hereditary particles circulate in the blood by transfusion experiments on rabbits. The failure of these experiments led him to reject this assumption, and in the 1870s he developed an alternative theory of heredity, which incorporated those parts of Darwin's theory that did not involve the transportation of hereditary particles throughout the system. He supposed that the fertilized ovum contains a large number of hereditary elements, (...) which he collectively called the "stirp," a few of which are patent, developing into particular cell types, while the rest remain latent; the latent elements can be transmitted to the next generation, while the patent elements, with rare exceptions, cannot since they have developed into cells. The problem with this theory is that it does not explain the similarity between parent and child unless there is a high correlation between latent and patent elements. Galton probably came to realize this problem during his subsequent statistical work on heredity, and he quietly dropped the idea that patent elements are not transmitted in Natural Inheritance (1889). Galton thought that brothers and sisters had identical stirps, and he attributed differences between them to variability in the choice of patent elements from the stirp, that is to say to developmental variability. He attributed the likeness of monozygotic twins to the similarity of their developmental environment. Galton's twin method was to track the life history changes of twins to see whether twins who were similar at birth diverged in dissimilar environments or whether twins who were dissimilar at birth converged in similar environments. It is quite different from the modern twin method of comparing the similarities between monozygotic and dizygotic twins, on the assumption that monozygotic twins are genetically identical whereas dizygotic twins are not. It has been argued that Galton foreshadowed Weismann's theory of the continuity of the germ-plasm, but this is only true in a weak sense. They both believed that the inheritance of acquired characters was either rare or impossible, but Galton did not forestall the essential part of Weismann's theory, that the germ-plasm of the zygote is doubled, with one part being reserved for the formation of the germ-cells.

Niche construction is the process whereby organisms, through their activities and choices, modify their own and each other’s niches. By transforming natural-selection pressures, niche construction generates feedback in evolution at various different levels. Niche-constructing species play important ecological roles by creating habitats and resources used by other species and thereby affecting the flow of energy and matter through ecosystems—a process often referred to as “ecosystem engineering.” An important emphasis of niche construction theory (NCT) is that acquired characters play (...) an evolutionary role through transforming selective environments. This is particularly relevant to human evolution, where our species has engaged in extensive environmental modification through cultural practices. Humans can construct developmental environments that feed back to affect how individuals learn and develop and the diseases to which they are exposed. Here we provide an introduction to NCT and illustrate some of its more important implications for the human sciences. (shrink)

August Weismann rejected the inheritance of acquired characters on the grounds that changes to the soma cannot produce the kind of changes to the germ-plasm that would result in the altered character being transmitted to subsequent generations. His intended distinction, between germ-plasm and soma, was closer to the modern distinction between genotype and phenotype than to the modern distinction between germ cells and somatic cells. Recently, systems of epigenetic inheritance have been claimed to make possible the inheritance of (...) acquired characters. I argue that the sense in which these claims are true does not challenge fundamental tenets of neo-Darwinism. Epigenetic inheritance expands the range of options available to genes but evolutionary adaptation remains the product of natural selection of ‘random’ variation. (shrink)
