Activity-Based Accounts of Mechanism and the Threat of Polygenic Effects

Accounts of ontic explanation have often been devised so as to provide an understanding of mechanism and of causation. Ontic accounts differ quite radically in their ontologies, and one of the latest additions to this tradition proposed by Peter Machamer, Lindley Darden and Carl Craver reintroduces the concept of activity. In this paper I ask whether this influential and activity-based account of mechanisms is viable as an ontic account. I focus on polygenic scenarios—scenarios in which the causal truths depend on more than one cause. The importance of polygenic causation was noticed early on by Mill (1893). It has since been shown to be a problem for both causal-law approaches to causation (Cartwright 1983) and accounts of causation cast in terms of capacities (Dupré 1993; Glennan 1997, pp. 605–626). However, whereas mechanistic accounts seem to be attractive precisely because they promise to handle complicated causal scenarios, polygenic causation needs to be examined more thoroughly in the emerging literature on activity-based mechanisms. The activity-based account proposed in Machamer et al. (2000, pp. 1–25) is problematic as an ontic account, I will argue. It seems necessary to ask, of any ontic account, how well it performs in causal situations where—at the explanandum level of mechanism—no activity occurs. In addition, it should be asked how well the activity-based account performs in situations where there are too few activities around to match the polygenic causal origin of the explanandum. The first situation presents an explanandum-problem and the second situation presents an explanans-problem—I will argue—both of which threaten activity-based frameworks.     

The Making of the Reliably Religious Boy

In Men, Religion, and Melancholia: James, Otto, Jung, and Erikson (D. Capps, 1997) and Men and Their Religion: Honor, Hope, and Humor (D. Capps, 2002), I argued that men are no less religious than women, but their religiousness is different from that of women because it has its psychological origins in the emotional separation between a boy and his mother around the ages of three to five. Employing Freud’s “Mourning and Melancholia” (S. Freud, 1917/1963) essay, I suggested that their religiousness is rooted in an ontological state of melancholy (which is different from the psychological state of depression). In Men and Their Religion I identified the religions of honor and of hope as the primary forms of male melancholic religion, and suggested that humor is a third form that may come to one’s assistance when one experiences the limitations of the other two religions. In this article, I focus on my own early adolescent years (age 11–14) and explain how one boy became reliably religious, that is, how he embraced or internalized the religions of honor and of hope. In the companion article, I will explain how these two religions were relativized—and thereby preserved—by the religion of humor.     

Achieving Our Goals in Life

In 2009 we distributed a questionnaire on the deadly sins. It combined two research instruments—The Life Attitudes Inventory constructed by Capps (Pastoral Psychology 37:229–253, 1989) and the Deadly Sins Scale developed by Nauta and Derckx (Pastoral Psychology 56:177–188, 2007). In a previous article (Capps and Haupt 2011) we reported on findings from the Life Attitudes Inventory. In this article we report on findings from the Deadly Sins Scale and then discuss the fact that an unusually high percentage of the respondents identified positively with the item “I achieve my goals in life.” We suggest that their identification with this item is a reflection of the fact that humans are hopeful by nature.     

Dream Skepticism and the Conditionality Problem

Recently, Ernest Sosa (2007) has proposed two novel solutions to the problem of dream skepticism. In the present paper, I argue that Sosa’s first solution falls prey to what I will refer to as the conditionality problem, i.e., the problem of only establishing a conditional—in this case, “if x, then I am awake,” x being a placeholder for a condition incompatible with dreaming—in a context where it also needs to be established that we can know that the antecedent holds, and as such can infer the consequent, i.e., “I am awake.” Sosa’s second solution, in terms of so-called reflective knowledge, is shown to land him in the dilemma of either facing yet another conditionality problem, or violating an internalist constraint that he explicitly grants the skeptic with respect to what kind of factors can be legitimately invoked in our account of how we may know the relevant antecedent. For these reasons, I conclude that Sosa has not solved the problem of dream skepticism.     

Speaking of Silence

In a previous article (Capps 2011) I discussed a short story and essay I wrote in high school and showed that themes that had figured prominently in my later writings were prefigured in these earlier writings. Invoking John Bunyan’s The Pilgrim’s Progress (1957) I concluded that the high school boy who lives inside of me has been my faithful companion throughout the years. In this article I focus on a sermon I preached in my senior year of high school and on several poems I wrote that year. The sermon and poems reflect my interest at the time in the harmful effects of silence on human relationships. An article that focused on the son of Saint Augustine (Capps 1990b) signaled my return to the issue of silence after a thirty-year hiatus. My subsequent reading of Alice Miller’s Breaking Down the Wall of Silence (1991) and The Truth Shall Set You Free (2001) helped me to understand why silence had been a personal issue for me. It also encouraged me to listen to the fledgling poet who lives within me and to appreciate his insights concerning silence and love.     

Cross-count identity,distinctness, and the theory of internal and external relations

Baxter (Australas J Philos 79:449–464, 2001) proposes an ingenious solution to the problem of instantiation based on his theory of cross-count identity. His idea is that where a particular instantiates a universal it shares an aspect with that universal. Both the particular and the universal are numerically identical with the shared aspect in different counts. Although Baxter does not say exactly what a count is, it appears that he takes ways of counting as mysterious primitives against which different numerical identities are defined. In contrast, I defend the idea—suggested, though not quite endorsed, by Baxter himself—that counts are independent dimensions of numerical identity. Different ways of counting are explained by the existence of these different sorts of identity (i.e., counts). For the instantiation of a universal by a particular, I propose one dimension concerned with the individuation of particulars (the p-count) and another dimension concerned with the individuation of universals (the u-count). On that basis, I give a clear definition of cross-count identity that explains its asymmetrical nature (i.e., the fact that particulars instantiate universals, but not vice versa). I extend the theory to a third dimension—that of time, or the t-count—and thereby defend Baxter’s ideas on change, and the contingency of instantiation. Baxter (Mind 97(388):575–582, 1988; Australas J Philos 79:449–464, 2001) proposes the related idea of composition as (cross-count) identity. Parts are individually cross-count identical with the wholes that they constitute, and they collectively share all aspects across counts with those wholes. I propose an innovation by which totality is shared distinctness across counts. The theory applies to both the totality of particulars that instantiate any given universal, and the totality of parts that constitute any given whole. I argue that this has several advantages over Armstrong’s view, which is based on a dubious external totalling relation. I also argue that Armstrong’s theory of numbers (or quantities) as internal relations ought to be rejected in favour of an account based on identity and distinctness. The paper concludes with a careful analysis of external relations in Baxter’s framework. I argue that we must recognise one further dimension of identity in order to differentiate between, e.g., the aspects of Abelard insofar as he loves Heloise and Abelard insofar as he loves Isobel. Each of these aspects is identical with Abelard and identical with loving-by, yet they must be in some way distinct. I therefore propose the r-count, in which multiple distinct relational properties are the very same relation (-part). The existence of these four independent dimensions explains the fact that particulars, universals, relations, and times are fundamentally different sorts of things in the ontology. Each is individuated with respect to a different dimension of identity.     

Anti-Luck Epistemology and Safety’s (Recent) Discontents

Anti-luck epistemology is an approach to analyzing knowledge that takes as a starting point the widely-held assumption that knowledge must exclude luck. Call this the anti-luck platitude. As Duncan Pritchard (2005) has suggested, there are three stages constituent of anti-luck epistemology, each which specifies a different philosophical requirement: these stages call for us to first give an account of luck; second, specify the sense in which knowledge is incompatible with luck; and finally, show what conditions must be satisfied in order to block the kind of luck with which knowledge was argued to be incompatible. What I’ll show here is that the modal account of luck offers a plausible story at the first stage and leads naturally to equally plausible lines to take at the second and third stages, at which a safety condition on knowledge is squarely motivated. There are, however, recent challenges—advanced by Jonathan Kvanvig (Philosophy and Phenomenological Research 77: 272–281, 2008); Kelly Becker (2007); and Jennifer Lackey (Australasian Journal of Philosophy 86(2):255–267, 2008), among others—to the plausibility of the safety-based anti-luck project I’ve sketched here at each of its three stages of development. Once I’ve made precise the challenges, I’ll show why none implies that we abandon the commitments of the safety-based anti-luck project at any of its stages. What we should conclude, then, is that a safety-condition on knowledge is motivated by independently defensible accounts of (1) what luck is; and (2) just how knowledge should be thought incompatible with it.     

Time for consciousness: intention and introspection

We assume that we can act—in at least some cases—by consciously intending to do so. Wegner (2002) appeals to empirical research carried out by Libet et al. (1983) to challenge this assumption. I argue that his conclusion presupposes a particular view of conscious intention. But there is an alternative model available, which has been developed by various writers in the phenomenological tradition, and most recently defended by Moran (2001). If we adopt this alternative account of conscious intention, Wegner’s argument no longer goes through, and we can retain the claim that our conscious intentions can give rise to action.     

Functions and emergence: when functional properties have something to say

In a recent paper, Bird (in: Groff (ed.) Revitalizing causality: Realism about causality in philosophy and social science, 2007) has argued that some higher-order properties—which he calls “evolved emergent properties”—can be considered causally efficacious in spite of exclusion arguments. I have previously argued in favour of a similar position. The basic argument is that selection processes do not take physical categorical properties into account. Rather, selection mechanisms are only tuned to what such properties can do, i.e., to their causal powers. This picture seems ultimately untenable in the light of further exclusion problems; but at the same time, it meets our explanatory demands. My purpose is therefore to show that there is a real antinomy with regard to evolved emergent properties. I develop a physicalist exclusion argument and then I go on to consider an argument that seems to establish that evolved emergent properties are causally efficacious, and propose a compatibilist solution. Finally, I very briefly consider what the proposed model may imply for the issue of mental causation.     

Realization, determination, and mechanisms

Several philosophers (e.g., Ehring (Nous (Detroit, Mich.) 30:461–480, 1996); Funkhouser (Nous (Detroit, Mich.) 40:548–569, 2006); Walter (Canadian Journal of Philosophy 37:217–244, 2007) have argued that there are metaphysical differences between the determinable-determinate relation and the realization relation between mental and physical properties. Others have challenged this claim (e.g., Wilson (Philosophical Studies, 2009). In this paper, I argue that there are indeed such differences and propose a “mechanistic” account of realization that elucidates why these differences hold. This account of realization incorporates two distinct roles that mechanisms play in the realization of mental (and other special science) properties which are implicit, but undeveloped, in the literature—what I call “constitutive” and “integrative” mechanisms. I then use these two notions of mechanism to clarify some debates about the relations between realization, multiple realizability, and irreducibility.     

Consciousness,Trauma, and Health: A Cognitive Systems Response to Payne,Walsh, and Oman

Religion and cognitive science contribute complementary understandings of the human person, and an integrated perspective can bridge clinical, spiritual, and philosophical resources to facilitate healing and growth. Drawing upon cognitive science and systems theory, I respond to Richard Payne, Mary Walsh, and Doug Oman’s comments on my Mind, Brain, and the Elusive Soul (Graves 2008; Oman 2011; Payne 2011; Walsh 2011).     

Conscious machines: Memory,melody and muscular imagination

A great deal of effort has been, and continues to be, devoted to developing consciousness artificially (A small selection of the many authors writing in this area includes: Cotterill (J Conscious Stud 2:290–311, 1995, 1998), Haikonen (2003), Aleksander and Dunmall (J Conscious Stud 10:7–18, 2003), Sloman (2004, 2005), Aleksander (2005), Holland and Knight (2006), and Chella and Manzotti (2007)), and yet a similar amount of effort has gone in to demonstrating the infeasibility of the whole enterprise (Most notably: Dreyfus (1972/1979, 1992, 1998), Searle (1980), Harnad (J Conscious Stud 10:67–75, 2003), and Sternberg (2007), but there are a great many others). My concern in this paper is to steer some navigable channel between the two positions, laying out the necessary pre-conditions for consciousness in an artificial system, and concentrating on what needs to hold for the system to perform as a human being or other phenomenally conscious agent in an intersubjectively-demanding social and moral environment. By adopting a thick notion of embodiment—one that is bound up with the concepts of the lived body and autopoiesis (Maturana and Varela 1980; Varela et al. 2003; and Ziemke 2003, 2007a, J Conscious Stud 14(7):167–179, 2007b)—I will argue that machine phenomenology is only possible within an embodied distributed system that possesses a richly affective musculature and a nervous system such that it can, through action and repetition, develop its tactile-kinaesthetic memory, individual kinaesthetic melodies pertaining to habitual practices, and an anticipatory enactive kinaesthetic imagination. Without these capacities the system would remain unconscious, unaware of itself embodied within a world. Finally, and following on from Damasio’s (1991, 1994, 1999, 2003) claims for the necessity of pre-reflective conscious, emotional, bodily responses for the development of an organism’s core and extended consciousness, I will argue that without these capacities any agent would be incapable of developing the sorts of somatic markers or saliency tags that enable affective reactions, and which are indispensable for effective decision-making and subsequent survival. My position, as presented here, remains agnostic about whether or not the creation of artificial consciousness is an attainable goal.     

Hey stud: Race, sex, and sports

This article is an examination of how the intersection of sport and race plays out in the sexualization of the sporting role of African American male athletes. Further, the article is an examination of the multiple roles the media, sport, and race play as these impact the public persona of African American male athletes in high-profile sports. The article concludes with a number of recommendations for ending the negative images of African American male athletes. To the white public, we are athletes, rappers, preachers, singers—and precious little else. We are also robberts, rapists, mentally deficient and sexually well endowed. —Ellis Cose, The Envy of the World: On Being a Black Man in America (2002; New York: Washington Square Press, 3–4) First of all, let me say good after ... good late afternoon. Because of the HIV virus I have attained, I will have to announce my retirement from the Lakers today. I just want to make clear, first of all, that I do not have the AIDS disease, because I know a lot of you want to know that, but the HIV virus. My wife is fine, she’s negative, so no problem with her. I plan on going on, living for a long time, bugging you guys like I always have. So you’ll see me around. I plan on being with the Lakers and the league—hopefully [Commissioner] David [Stern] will have me for a while—and going on with my life. I guess now I get to enjoy some of the other sides of living—that [were missed] because of the season and the long practices and so on. I just want to say that I’m going to miss playing. And I will now become a spokesman for the HIV virus because I want people, young people, to realize they can practice safe sex. And, you know, sometimes you’re a little naive about it and you think it could never happen to you. You only thought it could happen to, you know, other people and so on and on. And it has happened. —Magic Johnson—Press Conference at L.A. Lakers Compound Washington Post, November 9, 1991     

Humor and the Rebellious Spirit of the Early Adolescent Boy

In my companion article on the making of the reliably religious boy (D. Capps, 2006c) I presented my argument that, whereas the younger boy of three to five is becoming religious as a result of his emotional separation from his mother, the early adolescent boy (age 11–14) has become reliably religious in that he has developed a religious habit of mind, a habit reflected in his embrace of the religions of honor and hope. I presented myself as a case study in this regard. I noted, however, that there is a third form of religion, that of humor, and that it relativizes—and thereby preserves—the religions of honor and hope. I also noted that religion and spirituality are capable of being differentiated. I suggested that my own spirituality took the form of rebellion and that this spirit of rebellion fueled and was fueled by the religion of humor. Employing Freud’s writings on humor, I explain in this article how this works.     

The structure of lexical concepts

Jerry Fodor (Concepts: Where cognitive science went wrong. New York: Oxford University Press, 1998) famously argued that lexical concepts are unstructured. After examining the advantages and disadvantages of both the classical approach to concepts and Fodor’s conceptual atomism, I argue that some lexical concepts are, in fact, structured. Roughly stated, I argue that structured lexical concepts bear a necessary biconditional entailment relation to their structural constituents. I develop this account of the structure of lexical concepts within the framework of Pavel Tichy’s (The foundations of Frege’s logic. Berlin, New York: De Gruyter, 1988) theory of constructions. I argue that concepts are constructions which can be combined by way of Tichy’s construction-forming operations of composition and closure and an additional operation, simplification, which I propose in section 6. The last of these construction-forming operations plays a central role in my account of lexical concept structure. Stated generally, structured lexical concepts are a result of simplifying their structural constituents.     

Arguments,Meta-arguments,and Metadialogues: A Reconstruction of Krabbe,Govier, and Woods

Krabbe (2003, in F.H. van Eemeren, J.A. Blair, C.A. Willard and A.F. Snoeck Henkemans (eds.), Proceedings of the Fifth Conference of the International Society for the Study of Argumentation, Sic Sat, Amsterdam, pp. 641–644) defined a metadialogue as a dialogue about one or more dialogues, and a ground-level dialogue as a dialogue that is not a metadialogue. Similarly, I define a meta-argument as an argument about one or more arguments, and a ground-level argument as one which is not a meta-argument. Krabbe (1995, in F.H van Eemeren, R. Grootendorst, J.A. Blair, C.A. Willard and A.F. Snoeck Henkemans (eds.), Proceedings of the Third ISSA Conference on Argumentation, Sic Sat, Amsterdam, pp. 333–344) showed that formal-fallacy criticism (and more generally, fallacy criticism) consists of metadialogues, and that such metadialogues can be profiled in ways that lead to their proper termination or resolution. I reconstruct Krabbe’s metadialogical account into monolectical, meta-argumentative terminology by describing three-types of meta-arguments corresponding to the three ways of proving formal invalidity he studied: the trivial logic-indifferent method; the method of counterexample situation; and the method of formal paraphrase. A fourth type of meta-argument corresponds to what Oliver (1967, Mind 76, 463–478), Govier (1985, Informal Logic 7, 27–33), and Copi (1986) call refutation by logical analogy. A fifth type of meta-argument represents my reconstruction of arguments by parity of reasoning studied by Woods and Hudak (1989, Informal Logic 11, 125–139). Other particular meta-arguments deserving future study are Hume’s critique of the argument from design in the Dialogues Concerning Natural Religion, and Mill’s initial argument in The Subjection of Women about the importance of established custom and general feeling vis-à-vis argumentation.     

Whatever it is better to be than not to be

The Anselmian claim that God is that than which a greater cannot be thought in virtue of being ‘whatever it is better to be than not to be’ may be accused of incoherence or even unintelligibility. By proposing a non-relative but apparently meaningful analysis thereof, I attempt to defend it against such criticism. In particular, I argue that ‘whatever it is better to be than not to be’ can be plausibly interpreted so as to imply very many attributes traditionally predicated of that than which a greater cannot be thought. Central to this line of reasoning is the assumption that whatever is an actual moral being is greater, simpliciter, than whatever is not an actual moral being.     

Omniscience and worthiness of worship

At first glance, the properties being omniscient and being worthy of worship might appear to be perfectly co-instantiable. (To say that some properties are co-instantiable is just to say that it is possible that some object instantiate all of them simultaneously. Being entirely red and being a ball are co-instantiable; being entirely red and being entirely blue are not). But there are reasons to be worried about this co-instantiability, as it turns out that, depending on our commitments with respect to certain kinds of knowledge and notions of personhood, it might be the case that no being—God included—could instantiate both. In this paper, I lay out and motivate this claim before going on to consider a variety of responses—some more plausible than others—that may be offered by the theist.
