In the late 19th century, physiologists such as David Ferrier, Eduard Hitzig, and Hermann Munk argued that cerebral brain functions are localized in discrete structures. By the early 20th century, this became the dominant position. However, another prominent physiologist, Friedrich Goltz, rejected theories of cerebral localization and argued against these physiologists until his death in 1902. I argue in this paper that previous historical accounts have failed to comprehend why Goltz rejected cerebral localization. I show that Goltz adhered to a (...) falsificationist methodology, and I reconstruct how he designed his experiments and weighted different kinds of evidence. I then draw on the exploratory experimentation literature from recent philosophy of science to trace one root of the debate to differences in how the German localizers designed their experiments and reasoned about evidence. While Goltz designed his experiments to test hypotheses about the functions of predetermined cerebral structures, the localizers explored new functions and structures in the process of constructing new theories. I argue that the localizers relied on untested background conjectures to justify their inferences about functional organization. These background conjectures collapsed a distinction between phenomena they produced direct evidence for (localized symptoms) and what they reached conclusions about (localized functions). (shrink)

The Caesar problem arises for abstractionist views, which seek to secure reference for terms such as ‘the number of Xs’ or #X by stipulating the content of ‘unmixed’ identity contexts like ‘#X = #Y’. Frege objects that this stipulation says nothing about ‘mixed’ contexts such as ‘# X = Julius Caesar’. This article defends a neglected response to the Caesar problem: the content of mixed contexts is just as open to stipulation as that of unmixed contexts.

I argue that Kant’s mature political philosophy entails the provisionality thesis. The provisionality thesis asserts that in a world like ours, populated with beings sufficiently like us, acquired rights (rights to external objects of choice, including property, sovereignty and territory) are necessarily provisional. I motivate the standard view, which restricts the notion of provisional right to the state of nature and the transition from the state of nature to the civil condition. I then provide two textual arguments against it. I (...) conclude by reflecting on the normative implications of the provisionality thesis, arguing that they are more modest than has been formerly appreciated. (shrink)

1. The Commentariolum Petitionis is not in the Codex Mediceus of Cicero's correspondence with his brother Quintus, but it appears at the end of the letters to Quintus in the other manuscripts. It starts in the normal manner of a letter and is, or purports to be, a collection of tips on canvassing set in the particular context of M. Cicero's consular candidature in 64: a composition of his brother Quintus. It is printed as no. 12 in Tyrrell and Purser's (...) collection of Cicero's Letters. (shrink)

Contractarians aim to derive moral principles from the dictates of instrumental rationality alone. But it is well-known that contractarian moral theories struggle to identify normative principles that are both uniquely rational and morally compelling. Michael Moehler's recent book, *Minimal Morality* seeks to avoid these difficulties by developing a novel "two-level" social contract theory, which restricts the scope of contractarian morality to cases of deep and persistent moral disagreement. Yet Moehler remains ambitious, arguing that a restricted version of Kant's categorical imperative (...) is a uniquely rational principle of conflict resolution. We develop a formal model of Moehler's informal game-theoretic argument, which reconstructs a valid argument for Moehler's conclusion. This model, in turn, enables us to expose how a successful argument for Moehler's contractarian principle rests on assumptions that can only be justified by subtle yet significant departures from the standard conception of rationality. We thus extend our understanding of familiar contractarian difficulties by showing how they arise even if we restrict the scope of contractarian morality to a domain where its application seems both promising and necessary. We show that the problem lies not in contractarians' immodest ambitions but in the modest resources rationality can offer to satisfy them. (shrink)

This paper responds to the recent situationist critique of practical rationality and decision-making. According to that critique, empirical evidence indicates that our choices are governed by morally irrelevant situational factors and not durable character traits, and rarely result from overt rational deliberation. This critique is taken to indicate that popular moral theories in the Western tradition are descriptively deficient, even if normatively plausible or desirable. But we believe that the situationist findings regarding the sources of, or influences over, our moral (...) agency do not reflect durable features of human nature, and claim that these findings are a byproduct of a deficient approach to moral education. Existing models of moral education, which are “positive” in nature, do a poor job of developing virtuous people. Instead, we argue that a “negative” approach to moral education, traceable to Locke, Smith, and Rousseau, would be more successful. This strategy represents something of a compromise between the strategies adopted by thinkers like Rachana Kamtekar : 458–491 2004), who argues that traditional moral categories escape largely untouched by findings in social psychology, and John Doris :504–530 1998) and Gilbert Harman : 87–94 2003), who argue that findings in psychology prove our traditional moral theories are defective.

The examples of dynamic supertasks analyzed to date in the philosophical literature, in which both determinism and the classical laws of conservation of energy and momentum are violated, all share the important limitation of requiring material systems of infinite mass. This paper demonstrates that this limitation is not necessary. This has important consequences for the scope and meaning of such violations.

The paper shows a new example of nonuniqueness of the solutionto Newtonian equations of motion for infinite gravitational systems. Unlike otherexamples, the gravitational field presents no singularity, nor are the non-gravitational forcesintroduced in the model singular (in particular, there are no collisions). The result is also ofinterest because it points to an interesting limitation of the elementary (Newtonian) formulationof classical mechanics.

The paper presents a new paradox in the sphere of the classical mechanics of infinite systems. The paradox, which implies the existence of an interaction at a distance as well as gravitation, would seem to require an extension of the concept of mechanical explanation. However, it is not clear how such an extension might be carried out.

In this article I propose what I call the inverse spaceship paradox. The article's interest lies in the fact that, contrary to what appears to be an implicit agreement in the literature on indeterminism, it shows that coming from infinity can be a perfectly predictable and therefore deterministic process in a classical universe.
