While the roots of modern German sociology are often traced back to historicism, the importance of rational natural law in the inception of the founding work of German sociology, Gemeinschaft und Gesellschaft by Ferdinand Tönnies, intended as a ?creative synthesis? between rational natural law and romantic historicism, should not be overlooked. We show how in his earliest scholarly work on Thomas Hobbes and John Locke the shift in the meaning of the two concepts ?Gemeinschaft? and ?Gesellschaft? represents a (...) departure from early liberal enlightenment to a Weltanschauung marked by romantic authors such as Fichte, Novalis and Haller, by Schopenhauer, Nietzsche, Spencer and Marx, notwithstanding Tönnies' adherence to the political and social values of a liberal civil society.

The most prominent recent interpretations of Kantian ethics place rational nature at the centre of the theory: I must respect rational nature, whether in myself or in others, because rational nature has a special status as the source of all other values. It is not obvious what it is for something to be the source of value, nor whether rational nature could play this role, but until these issues are settled the coherence (...) of Kantian ethics is in question. In this article I offer an explanation of what it is for rational nature to be the source of value, I show that this claim is an important element of Kant's moral theory, and I defend this conception of value.

Familiar accounts have it that one explains thoughts or actions by showing them to be rational. It is common to find that the standards of rationality presupposed in these accounts are drawn from what would be thought to be aprioristic sources. I advance an argument to show this must be mistaken. But, recent work in epistemology and on rationality takes a less aprioristic approach to such standards. Does the new (psychological or cognitive scientific) realism in accounts of rationality itself (...) significantly improve the prospects for unproblematic forms of rationalizing explanation? Do earlier misgivings about rationalizing explanation ring hollow when the rationality to be attributed is "naturalized"? Answer: while explanation in terms of naturalized rationality would be free of one fatal flaw possessed by explanation in terms of rationality understood in the traditional fashion, it would yet have parallel flaws.

Natural law theory has been undergoing a revival, especially in political philosophy and jurisprudence. Yet, most fundamentally, natural law theory is not a political theory, but a moral theory, or more accurately a theory of practical rationality. According to the natural law account of practical rationality, the basic reasons for actions are basic goods that are grounded in the nature of human beings. Practical rationality aims to identify and characterize reasons for action and to explain how choice between actions (...) worth performing can be appropriately governed by rational standards. These standards are justified by reference to features of the human goods that are the fundamental reasons for action. This book is a defence of a contemporary natural law theory of practical rationality, demonstrating its inherent plausibility and engaging systematically with rival egoist, consequentialist, Kantian and virtue accounts.

Repeatedly and successfully, the celebrated Harvard philosopher Robert Nozick has reached out to a broad audience beyond the confines of his discipline, addressing ethical and social problems that matter to every thoughtful person. Here Nozick continues his search for the connections between philosophy and "ordinary" experience. In the lively and accessible style that his readers have come to expect, he offers a bold theory of rationality, the one characteristic deemed to fix humanity's "specialness." What are principles for? asks Nozick. We (...) could act simply on whim, or maximize our self-interest and recommend that others do the same. As Nozick explores rationality of decision and rationality of belief, he shows how principles actually function in our day-to-day thinking and in our efforts to live peacefully and productively with each other. Throughout, the book combines daring speculations with detailed investigations to portray the nature and status of rationality and the essential role that imagination plays in this singular human aptitude.

Contending that only a normative theory of rationality can be adequate to the complexities of the subject, this book explains and defends the view that rationality consists of the intelligent pursuit of appropriate objectives. Rescher considers the mechanics, rationale, and rewards of reason, and argues that social scientists who want to present a theory of rationality while avoiding the vexing complexities of normative deliberations must amend their perspective of the rational enterprise.

Reason and Nature investigates the norms of reason--the standards which contribute to determining whether beliefs, inferences, and actions are rational. Nine philosophers and two psychologists discuss what kinds of things these norms are, how they can be situated within the natural world, and what role they play in the psychological explanation of belief and action. Current work in the theory of rationality is subject to very diverse influences ranging from experimental and theoretical psychology, through philosophy of logic and (...) language, to metaethics and the theory of practical reasoning; this range is well represented here.

A tempting argument for human rationality goes like this: it is more conducive to survival to have true beliefs than false beliefs, so it is more conducive to survival to use reliable belief-forming strategies than unreliable ones. But reliable strategies are rational strategies, so there is a selective advantage to using rational strategies. Since we have evolved, we must use rational strategies. In this paper I argue that some criticisms of this argument offered by Stephen Stich fail (...) because they rely on unsubstantiated interpretations of some results from experimental psychology. I raise two objections to the argument: (i) even if it is advantageous to use rational strategies, it does not follow that we actually use them; and (ii) natural selection need not favor only or even primarily reliable belief-forming strategies.

A popular objection to theistic commitment involves the idea that faith is irrational. Specifically, some seem to put forth something like the following argument: (P1) Everyone (or almost everyone) who has faith is epistemically irrational, (P2) All theistic believers have faith, thus (C) All (or most) theistic believers are epistemically irrational. In this paper, I argue that this line of reasoning fails. I do so by considering a number of candidates for what faith might be. I argue that, for each (...) candidate, either (P1) is false or (P2) is false. Then, I make two positive suggestions for how faith can be epistemically rational but nonetheless have a unique relationship to evidence: one, that Jamesian self-justifying attitudes describe a distinctive kind of faith in oneself and others, and two, that faith is not solely based on empirical evidence.

A discussion of George Bealer's conception and defense of rational intuition as a basis of philosophical knowledge, under three main heads: a) the phenomenology of intellectual intuition; b) the status of such intuition as a basic source of evidence, and the explanation of what gives it that status; and c) the defense of intuition against those who would reject it and exclude it on principle from the set of valid sources of evidence.

The generation of animals was a difficult phenomenon to explain in the seventeenth century, having long been a problem in natural philosophy, theology, and medicine. In this paper, I explore how generation, understood as epigenesis, was directly related to an idea of rational nature. I examine epigenesis—the idea that the embryo was constructed part-by-part, over time—in the work of two seemingly dissimilar English philosophers: William Harvey, an eclectic Aristotelian, and Margaret Cavendish, a radical materialist. I chart the ways (...) that they understood and explained epigenesis, given their differences in philosophy and ontology. I argue for the importance of ideas of harmony and order in structuring their accounts of generation as a rational process. I link their experiences during the English Civil war to how they see nature as a possible source for the rationality and concord sorely missing in human affairs. (shrink)

Students systematically and deliberately apply rule‐based but erroneous algorithms to solving unfamiliar arithmetic problems. These algorithms result in erroneous solutions termed rational errors. Computationally, students' erroneous algorithms can be represented by perturbations or bugs in otherwise correct arithmetic algorithms (Brown & VanLehn, 1980; Langley & Ohilson, 1984; VanLehn, 1983, 1986, 1990; Young S O'Sheo, 1981). Bugs are useful for describing how rational errors occur but bugs are not sufficient for explaining their origin. A possible explanation for this is (...) that rational errors are the result of incorrect induction from examples. This prediction is termed the “induction hypothesis” (VanLehn, 1986). The purpose of the present study was to: (a) expand on post formulations of the induction hypothesis, and (b) use a new methodology to test the induction hypothesis more carefully than has been done previously. The first step involved teaching participants a new number system called NewAbacus, a written modification of the abacus system. The second step consisted of dividing them into different groups, where each individual received an example of only one port of the NewAbacus addition algorithm. During the third and final step, participants were instructed to solve both familiar and unfamiliar types of addition problems in NewAbacus. The induction hypothesis was supported by using both empirical and computational investigations. (shrink)

In response to those who see rational deliberation as a source of epistemic norms and a model for well-functioning scientific inquiry, Solomon cites evidence that aggregative techniques often yield better results; deliberative processes are vulnerable to biasing mechanisms that impoverish the epistemic resources on which group judgments are based. I argue that aggregative techniques are similarly vulnerable and illustrate this in terms of the impact of gender schemas on both individual and collective judgment. A consistently externalist and socially naturalized (...) approach calls for symmetrical treatment of these strategies for capitalizing on what groups know. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Leibniz and the Rational Order of Nature by Donald RutherfordChristia MercerDonald Rutherford. Leibniz and the Rational Order of Nature. New York: Cambridge University Press, 1995. Pp. xiii + 301. Cloth, $54.95. Paper, $18.95.During the twentieth century, scholars of Leibniz have mostly ignored his theology. The tide has recently turned, however, and a few brave souls have begun to disentangle the subtle complications of the (...) relations between Leibniz’s philosophical theology and the rest of his thought. Donald Rutherford is such a brave soul. In his book, he intends to recover “the theodicy as an essential part of Leibniz’s philosophy” (1). To this end, he offers “a comprehensive interpretation of Leibniz’s metaphysical theories—particularly those of his late writings,” and attempts to show “how theodicy [End Page 139] and metaphysics inform each other in his thought” (1). The book has three parts and ten chapters. In the three chapters of Part I, Rutherford “focuses on Leibniz’s theodicy: his vindication of divine justice, the character of the goods that make this the best of all possible worlds, and the special role assigned to rational minds as agents within God’s providential plan for the world” (1). In the three chapters of Part II, Rutherford turns his attention to “Leibniz’s conception of metaphysics as a rational science” and to the notion of substance at its center (2). Finally, in the four chapters of Part III, Rutherford presents an account of Leibniz’s late metaphysics.The structure of Rutherford’s general argument is ingenious. Most fundamentally, he argues that “the guiding force behind” the theodicy is a commitment to reason: “reason as it directs the creative will of God, reason as it is... realized in the intelligible order of the created world, and reason as it helps human beings discern and appreciate that order.” Moreover, “Leibniz’s metaphysical theories are designed to promote the goals of his theodicy” by evidencing as much as possible that rational order (2). Therefore, once we see the metaphysics in light of its theological goal, the close interconnections among its parts will become evident. As Rutherford nicely puts it: “The Leibniz who emerges in this book is one for whom theoretical and practical ends are inextricably linked” (3).In Part I, Rutherford describes the project of the theodicy and, along the way, offers answers to questions which have plagued scholars for decades: What is the relation between variety and simplicity as (apparently conflicting) criteria of worldly goodness? How is the demand for the maximization of perfection related to the (apparently conflicting) commitment to the optimization of the happiness of rational creatures? How can there be different orders and harmonies in one world? Although many of Rutherford’s proposals are both plausible and interesting, they are painted with such broad strokes that they are sometimes difficult to evaluate. Some of the missing details are supplied later in the book, but others are not. For example, a clear picture of the relation between God’s power, goodness, will, and rationality never emerges. In Part II, Rutherford surveys some important texts and topics which concern Leibniz’s methodology, and he presents an intelligent interpretation of Leibniz’s theory of substance. There is much that is interesting here. In Part III, Rutherford is at his best. He ties together many of the separate strands of the late philosophy and tells a plausible story about monads, panorganism, and corporeal substance. This is a genuine achievement and one that will generate a lot of discussion.While I applaud Rutherford’s attempt to construct a coherent account of Leibniz’s philosophy, it is my opinion that he has attached too much importance both to the rational order that is supposed to please the faculty of reason, whether divine or human, and to that faculty itself. According to the Christianized Platonism that Leibniz learned (among many other things) from his teachers in Leipzig, it is the intellect or understanding (intellectus) and not the reason that comes to know the most fundamental truths; and moreover the goodness that created beings (and their interrelations) are supposed to have is based on the fact that they are expressions of God...

In the first part of this paper I will characterize the specific nature of rational intuition. It will be claimed that rational intuition is an evidential state with modal content that has an a priori source. This claim will be defended against several objections. The second part of the paper deals with the so-called explanationist objection against rational intuition as a justifying source. According to the best reading of this objection, intuition cannot justify any judgment since (...) there is no metaphysical explanation of its reliability. It will be argued that in the case of intuition the very demand of such an explanation is based on a category mistake. (shrink)

In two recent papers, I criticized Ronald N. Giere's and Larry Laudan's arguments for 'naturalizing' the philosophy of science (Siegel 1989, 1990). Both Giere and Laudan replied to my criticisms (Giere 1989, Laudan 1990b). The key issue arising in both interchanges is these naturalists' embrace of instrumental conceptions of rationality, and their concomitant rejection of non-instrumental conceptions of that key normative notion. In this reply I argue that their accounts of science's rationality as exclusively instrumental fail, and consequently that their (...) cases for 'normatively naturalizing' the philosophy of science fail as well.

This volume exposes naturalism’s unnaturalness and defends theism’s naturalness and greater explanatory power to account for wide-ranging phenomena in the world and human experience. A broadening of naturalism to accommodate these features means borrowing heavily from—and thus more closely resembling—a theistic worldview.

This essay argues that Mark C. Murphy's original contribution to natural law ethics succeeds in finding a way between older metaphysical and newer purely practical approaches in this genre. Murphy's reconstruction of the function argument, critique of subjectivist theories of well-being, and rigorous formulation of a flexible welfarist theory of value deserve careful attention. I defend Kant against Murphy's critique and argue that Murphy faces the problem of showing that all his basic goods are morally inviolable. Although I endorse Murphy's (...) critique of radical virtue ethics, I raise objections to the basic moral norms he derives from his list of goods, and to the analysis of peace of mind and happiness as basic goods.

The paper shows why and how an empirical study of fast-and-frugal heuristics can provide norms of good reasoning, and thus how (and how far) rationality can be naturalized. We explain the heuristics that humans often rely on in solving problems, for example, choosing investment strategies or apartments, placing bets in sports, or making library searches. We then show that heuristics can lead to judgments that are as accurate as or even more accurate than strategies that use more information and computation, (...) including optimization methods. A standard way to defend the use of heuristics is by reference to accuracy-effort trade-offs. We take a different route, emphasizing ecological rationality (the relationship between cognitive heuristics and environment), and argue that in uncertain environments, more information and computation are not always better (the “less-can-be-more” doctrine). The resulting naturalism about rationality is thus normative because it not only describes what heuristics people use, but also in which specific environments one should rely on a heuristic in order to make better inferences. While we desist from claiming that the scope of ecological rationality is unlimited, we think it is of wide practical use. (shrink)

It is often believed that the only alternative to an idealist conception of natural phenomena excludes both the presence of objective universal forms and their progression towards higher forms as the finality of processes in the natural world. Realism regarding the universal and teleological approaches regarding processes are signs of idealism. Therefore, materialism, it would seem, must conform to a nominalist and mechanical view of nature. However, an intelligent materialist reading of idealism’s classics reveals a more complex scenario. A (...) real fact is expressed in a mystical fashion in idealism’s conceptions of objective universals and teleology. This article attempts to show such a real fact in its authentic (materialist) form. With that goal in mind, the present article discusses the notion of nature’s alienation, the distinction between abstract and concrete universals, and the concept of dialectical interaction. The natural-historical emergence of a higher form of matter’s organization assimilates, as its organs, the conditions that preceded it in time, transforming itself into an active producer of such conditions. That is the secret glimpsed but not correctly understood by idealism that a consistent materialist should not ignore. (shrink)

Donald Davidson's argument for the nonlawlike nature of psycho-physical generalizations is discussed and refuted. It is shown that his appeals to the rational and holistic character of intentional description do not support his conclusion of anomalism. An alternative methodological role is suggested for the concept of rationality in application to current empirical research in cognitive psychology.
