Verificationism has been a hallmark of logical empiricism. According to this principle, a sentence is insignificant in a certain sense if its truth value cannot be determined. Although logical empiricists strove for decades to develop an adequate principle of verification, they failed to resolve its problems. This led to a general abandonment of the verificationist project in the early 1960s. In the last 50 years, this view has received tremendously bad press. Today it is mostly regarded as an outdated historical (...) concept. Theories that have evolved since the abandonment of verificationism can, however, help overcome some of its key problems. More specifically, an adequate criterion of significance can be derived from a combination of modern theories of justification and belief revision, along with a formal semantics for counterfactuals. In view of these potential improvements, the abandonment of verificationism appears premature. Half a century following its decline, it might be about time to revisit this disreputable view. The author argues in favor of a weak form of verificationism. This approach could be referred to as minimal verificationism, as it involves a weakening of traditional verificationist principles in various respects while maintaining their core idea. (shrink)

The AGM success postulates for belief expansions and revisions have been widely criticized. This has resulted in the development of a number of non-prioritized belief change theories that violate these postulates. It is shown that we must also discard the monotony postulate for belief expansions if we abandon the success postulates. Non-prioritized belief change theories should instead fulfill a weaker postulate, which we call Conditional Monotony.

Belief revision theories aim to model the dynamics of epistemic states. Besides beliefs, epistemic states comprise most importantly justificational structures. Typically, belief revision theories, however, model the dynamics of beliefs while neglecting justificational structures over and above logical relations. Despite some awareness that this approach is problematic, how devastating the consequences of this neglect are has not yet been fully grasped. In this paper, I argue that taking justificational structures into account could solve four well-known problems of belief revision.

This is a description of an avian-shaped feature that rests below a network of cellular structures found on a mound within the Argyre Basin of Mars in Mars Global Surveyor image M14-02185, acquired on April 30, 2000, and released to the public on April 4, 2001. The area examined is located near 48.0° South, 55.1° West. The formation is approximately 2,400 meters long from the tip of its beak to the tip of its farthest tail feather. There is a minimum (...) of six different variations in appearance of the surface material over this small area. Utilizing the public targeting request form provided on the Mars Global Surveyor (MGS) website, co-author Miller secured a second image of the area that was obtained on July 3, 2006, showing this feature under different conditions S20-00165. The new image was then released to the public on August 11, 2006. A third image of the formation identified as MGS S13-01480 was acquired on December 15, 2005, and although officially processed on June 20, 2006, it was not made available to the public until August 22, 2009, on NASA’s Planetary Data System (PDS) website. All three of the MGS images reveal defining aspects of this avian feature, including a head, beak, body, eye, leg, foot, toes, wing, and feathers. When taken together, these components induce the visual impression of an avian-shaped formation that exhibits a unique set of proportional features. Adjoining this formation is a composite of complex cellular features that form a compartmentalized infrastructure. The three authors who are veterinarians provide a critical analysis of the avian features, and the geologist and geoscientist authors examine natural mechanisms that could contribute to the formation of this feature. An extensive search of comparable regions within and beyond the area of the Argyre Basin was conducted. A list of these sites is provided, and terrestrial comparisons are also offered. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Calvin's Political Theology and the Public Engagement of the Church: Calvin's Two Kingdoms by Matthew J. TuiningaGuenther ("Gene") HaasCalvin's Political Theology and the Public Engagement of the Church: Calvin's Two Kingdoms Matthew J. Tuininga CAMBRIDGE: CAMBRIDGE UNIVERSITY PRESS, 2017. 258 PP. £69.99 / £27.99In recent years, a vigorous debate has arisen within Reformed circles concerning the nature of the two kingdoms theology of John Calvin. Although all recognize (...) that Calvin articulated a distinction between the spiritual kingdom of the church and the political kingdom of the state, there is disagreement over [End Page 211] the nature of the engagement of Christians with the temporal kingdom and over what should guide the state in enacting civil justice and order.The Kuyperian Neo-Calvinist movement holds a transformationalist understanding of the engagement of members of the spiritual kingdom with all vocations and spheres of life. Alternatively, two kingdoms Reformed theologians, such as David VanDrunen and Michael Horton, argue that the Reign of Christ is confined to the spiritual kingdom and must not be brought to bear directly on the temporal kingdom. Matthew Tuininga's book supports the latter view in his exposition of Calvin's political theology. Tuininga argues that Calvin articulated a sharp distinction between church and political society, such that politics is seen not as "a means of transforming society into the kingdom of God according to the dictates of Christian scripture, but as an endeavour to secure temporal order and civil righteousness in accord with reason, natural law, and the virtues of charity and prudence" (1).Tuininga begins by situating Calvin and his two kingdoms theology in their historical and political context, indicating Calvin's concern for the autonomy of church contra government interference. The central chapters (3–6) present the eschatological basis for Calvin's two kingdoms doctrine and detail the development of this theme in Calvin's thought. The Kingdom of God is identified with the church and its spiritual authority. It is distinct from the state's temporal authority, whose role is to maintain civil righteousness and order. To support this distinction between the mandate of the two kingdoms, Tuininga presents in chapter 7 the novel, and debatable, claim that Calvin holds to two covenants of God with Israel: the covenant of grace made with Abraham and confirmed at Sinai and the narrower covenant of the law for Israel's national life, in which God's blessings and punishments were conditional on Israel's obedience and disobedience. Although this legal covenant—with its earthly and temporal character—is embedded in the broader covenant of grace, it is abolished with the fulfillment of the covenant of grace in the coming of Christ. Only the covenant of grace—with its heavenly, inward, and spiritual character—remains in force for God's people today.Chapter 8 argues that Calvin's views on the mandate of the magistrate to protect religion and enact public justice is based not on appeals to scripture but to reason, the evidence of national laws, and natural philosophy. In chapter 9 Tuininga unfolds the implications of Calvin's two kingdoms theology for Christian political involvement in society. And in his conclusion, Tuininga unfolds numerous ways that this two kingdoms theology can guide contemporary Christians' engagement with modern liberal democracies.This work is a welcome exposition of Calvin's political theology to support the two kingdoms theology. However, in addition to the novel, and debatable, claim that God made two covenants with Israel, this reviewer finds that Tuininga's exposition fails to incorporate key points in Calvin's thought: the failure of civil rulers' to enact natural law faithfully and consistently (2.2.13, 23; 3.14.2), [End Page 212] the description of the calling of civil authority as "holy and lawful before God … the most sacred and by far the most honorable of all callings" (4.20.4), and Calvin's claim that the best rulers are those governing according to both tables of the Decalogue (4.20.9–11). Nevertheless, this book is an important contribution to the ongoing debate and should be widely read.Guenther ("Gene") HaasRedeemer University CollegeCopyright © 2018... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Human Rights and the Ethics of Globalization by Daniel E. Lee and Elizabeth J. LeeGuenther "Gene" HaasHuman Rights and the Ethics of Globalization Daniel E. Lee and Elizabeth J. Lee Cambridge: Cambridge University Press, 2010. 264 pp. $27.99While there have been numerous books written on the nature of rights in a world of globalization, this book fills a gap by presenting a thoughtful and balanced discussion that is (...) firmly grounded in ethical theory yet takes into account the concerns of both nongovernmental organizations (NGOs) and the realities of the business world. The authors acknowledge that there can be naive troublemakers in NGOs and greedy people in business as well as socially concerned people in both groups.The book is divided into three parts. Part 1 deals with the philosophical foundations for addressing ethical issues in business within the context of globalization. Here the authors advocate for a limited, carefully defined notion of rights, properly noting that not everything of ethical significance falls under the notion of rights. The important distinction they make is between negative rights (the rights to life and freedom), which oblige us never to harm others, and positive rights (rights of entitlement, such as education, medical care, housing), which depend upon the various types of relationships, voluntary or involuntary, in which people find themselves. The former apply universally to neighbors near and far; the latter, because they are defined by relationships, apply primarily to neighbors near to us. With globalization distant neighbors often become near neighbors—for example, when a company builds a production facility in another country. In view of this, the authors argue that the Enlightenment’s individualistic understanding of rights is incomplete. A fuller version of rights (rooted in Aristotle) situates all humans in social communities where mutual charitable treatment is better suited to promoting human flourishing. With this in mind, the authors use the second form of Kant’s categorical imperative (“Always treat others as ends”) to map out some helpful practical guidelines for multinational corporations that are conducive to human well-being. Such guidelines seek to take into consideration all the constituencies that these organizations are called to serve—including shareholders, customers, employees, suppliers, and communities of location.In part 2 the authors draw on these philosophical foundations and practical guidelines to discuss ethical issues related to business practices in four different [End Page 198] countries: respect for human rights in China given the widespread practice of outsourcing; the condition of workers in Liberia where Firestone is the largest employer; free trade and fair trade issues related to coffee growers in Ethiopia; and the question of whether low-wage factories (maquiladoras) in Mexico exploit workers or provide economic opportunity for them. The authors provide a fair evaluation of each situation rooting their discussion in the nature of each respective business and the conditions over which it has direct control.Part 3 deals with the possibilities and challenges of dealing with multinational corporations that do not respect human rights. Although many argue for sanctions and treaty provisions, the authors argue that these approaches have their limitations. As an alternative, they recommend the Alien Tort Claims Act as the most promising means of enforcing human rights standards among American multinational corporations with overseas operations.This is an insightful and balanced book on human rights and social ethics precisely because it has a positive view of markets and is optimistic about achieving greater social responsibility in the business world. It will be helpful to all committed to promoting ethical business practices in a growing global economy—not only in the church and academy but also in the legal community and business world and in NGOs.Guenther HaasRedeemer University CollegeCopyright © 2013 Society of Christian Ethics...

Although the AGM theory established a paradigm for the theory of belief revision, which is generally regarded as a kind of standard in the field, it is also frequently criticized as inadequate because it neglects justificational structures. Other theories of belief revision are similarly remiss in this regard. So far, little has been done to address this shortcoming. This paper aims to fill this gap. Following a critical analysis of the AGM theory, a justification operator is introduced as a formal (...) means to incorporate justificational structures into a belief revision theory. An AGM style belief revision theory is proposed that is based on such a justification operator. The theory is presented in an axiomatic form. Representation theorems link the axioms with constructive belief change mechanisms. The proposed theory addresses the problems of the AGM theory and similar approaches that neglect justificational structures. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Prophetic Evangelicals: Envisioning a Just and Peaceable Kingdom ed. by Bruce Ellis Benson, Malinga Elizabeth Berry, and Peter Goodwin Heltzel, and: Bearing True Witness: Truthfulness in Christian Practice by Craig HoveyGuenther “Gene” HaasReview of Prophetic Evangelicals: Envisioning a Just and Peaceable Kingdom EDITED BY BRUCE ELLIS BENSON, MALINGA ELIZABETH BERRY, AND PETER GOODWIN HELTZEL Grand Rapids, MI: Eerdmans, 2012. 225 pp. $35.00Review of Bearing True Witness: Truthfulness in (...) Christian Practice CRAIG HOVEY Grand Rapids, MI: Eerdmans, 2011. 258 pp. $27.00Christian thought and practice in North America—especially in the evangelical world—has undergone significant changes in recent years. Prophetic Evangelicals and Bearing True Witness deal with two areas where this is evident: first, the attention many evangelicals are now giving to social justice and peace and, second, their determination to witness to the truth about Christ in a manner consistent with the Christian gospel. Prophetic evangelicals is the name the editors apply to a new generation of evangelicals who believe that the gospel of Christ requires a commitment to proclaim and embody “the just and peaceable kingdom” (2). These evangelicals view Jesus as inaugurating “a new social order that is a radical alternative to the order of empire” (7).This trend among evangelicals to move beyond the preaching of the gospel in a narrow sense (over against the liberals’ emphasis on social justice) is the culmination of a trend that has been happening since the publication in 1947 of Carl Henry’s The Uneasy Conscience of Modern Fundamentalism. What is new about many younger evangelicals in recent decades is their embrace of the Anabaptist perspective on justice and peace. It is clear in the introductory and concluding chapters by the editors—with their appeals to John Howard Yoder and Stanley Hauerwas and their references to the “cultural captivity” of the church—that this is the trend they have in mind. One also reads hints of liberation theology in the editors’ references to the needs of the people being “holy” (12), to God’s being on the side of—and the gospel always being in favor of—the “least” (47), and to a critique of “the order of empire” (7). Of course, [End Page 221] non-Anabaptist evangelicals are also concerned with these themes as part of their commitment to justice and peace. But it is the distinctive emphasis of this book—with some exceptions among the contributors—that it highlights the ways Anabaptist evangelicals are prophetic.The chapters consist of expositions on the following biblical themes: creation, shalom, justice, kingdom, news, Mary, the cross, church, freedom, reconciliation, resurrection, and hope. The authors include a wide range of evangelicals: from a Kuyperian (Vincent Bacote on creation) to a committed Anabaptist (David Gushee on shalom), to postcolonial Christians (Gabriel Salguero on the cross, and Raymond Alfred on freedom). Although the term is slippery, the inclusion of two contributors raises the question about who the editors consider to be an “evangelical”: Helen Slessarov-Jamir (on justice) agrees with her students’ desire not to learn theology from “dead white men” (77) and embraces religious pluralism (85); Pamela Lightsey (on reconciliation) embraces liberalism and liberation theology and calls herself a “womanist theologian” (169).The chapters contain a diversity of contributions in length and quality. Some are good, short expositions of themes: creation (Bacote), kingdom (Christian Collins Winn), Mary—actually about suffering—(Ruth Padilla DeBorst), church (John Franke), and resurrection (Cherith Fee Nordling). Gushee’s chapter contains a good exposition of the Anabaptist view of shalom, along with typical sweeping statements about the “Constantinian compromise” and the evangelical compromise with the state (72). Two chapters deserve special recognition. Chris Boesel’s chapter, “News,” is an excellent account of the Christian call to justice as part of the full goodness of the gospel. He criticizes both liberal-progressive and evangelical-conservative assumptions about the church’s mission and calls for a “recovering evangelical faith” that pursues justice with repentance, humility, and a reliance on the Holy Spirit. Telford Work’s chapter, “Hope,” also articulates a perceptive critique of the activism of both the Christian Right and the Christian Left. Rejecting all alignments with worldly power, he calls on the... (shrink)

This is an examination of an avian-shaped feature that rests below a network of cellular structures found on a mound within the Argyre Basin of Mars. The area examined is located near 48.0° south and 55.1° west. A set of four supportive images provided by the Mars Global Surveyor and Mars Reconnaissance Orbiter spacecraft show the feature is persistent over a period of more than 20 years. The images reveal defining aspects of this avian feature, including a head, beak, body, (...) eye, legs, feet, toes, wing, and feathers. When taken together, these components induce the visual impression of an avian-shaped formation that exhibits a unique set of proportional features. The claim of artificial construction is offered and the geoscientist author will examine natural mechanisms that could contribute to the creation of this feature and the testimony of three veterinarians will provide a critical analysis of the avian features. A terrestrial comparison of aesthetic and iconographic motifs is investigated. The request for further study and additional images of these structural components are also encouraged. (shrink)

This is an analysis of a large facial formation set within a glacial moraine along the southeast corner of Alberta, Canada, known as the Badlands Guardian. The formation is presented in one aerial and three satellite images acquired over the past 70 years by the Alberta Department of Lands & Forests and Google Earth. The images reveal a profiled portrait of a human head wearing a feathered headdress. The facial features include an eye, nose, mouth, chin, neck, and jawline. The (...) headdress consists of a headband containing a staggered set of feather-shaped extensions. When taken together these aesthetic features create the visual impression of a left-facing portrait of an indigenous tribesman wearing a feathered headdress. A claim of intelligent design is offered and a geologist and geoscientist examine natural mechanisms that could contribute to the formation of these aesthetic features. A comparison of the iconographic tribal motifs of both North and South America is presented and a request for an extensive ground exploration and additional satellite images of this formation is encouraged.
