Retrieval failure, rehearsal deficiency, and short-term memory loss in the aphasic adult

Studies show that aphasic patients typically are grossly impaired in short-term memory performance. Since aphasics generally experience difficulty in word retrieval, it is conceivable that short-term memory loss is partially the result of verbal rehearsal deficiency which, in turn, is caused by the word retrieval problem. This paper reports an experiment in which five aphasic adults were nonverbally to recall individualized lists of pictures they could easily name and lists of pictures they could not name. Final items in the two lists were recalled with equal accuracy; this was expected in that the recency effect usually reflects sensory rather than verbal storage. Initial items were recalled with greater accuracy than middle-list items in the nameable sets but not in the unnameable sets. This primacy effect suggests the aphasics rehearsed the nameable pictures, but both lists were recalled so poorly that rehearsal deficit was considered responsible for no more than a fraction of the aphasics' reduction in short-term memory.     

Property rights and genetic engineering: Developing nations at risk

Eighty percent of (commercial) genetically engineered seeds (GES) are designed only to resist herbicides. Letting farmers use more chemicals, they cut labor costs. But developing nations say GES cause food shortages, unemployment, resistant weeds, and extinction of native cultivars when “volunteers” drift nearby. While GES patents are reasonable, this paper argues many patent policies are not. The paper surveys GE technology, outlines John Locke’s classic account of property rights, and argues that current patent policies must be revised to take account of Lockean ethical constraints. After answering a key objection, it provides concrete suggestions for implementing its ethical conclusions.     

Challenging the State: Teaching Alternative Historiographies in Early Modern Politics

This article argues that we can improve the way we teach early modern political philosophy if we introduce students to alternative views about the development of the state. First, it summarizes the work of contemporary philosophers and historians who are critical of the modern state. Second, it points out ways in which early social contract theorists take the state for granted. Third, it argues that alternative views about the development of the state can help students take a more critical perspective on standard works of early modern political philosophy. Fourth, it argues that these alternative views will help students better understand dissenting voices in early modern political philosophy.     

The coherence of cohesion in the later Leibniz

This paper expounds and critically assesses G. W. Leibniz’s mature theory of the cohesion of material bodies. Leibniz’s later view of cohesion was forged in polemical engagement with the views of John Locke and the Dutch natural philosopher Nicolaas Hartsoeker and it is in Leibniz’s response to Locke in his New Essays on Human Understanding, and especially his correspondence with Hartsoeker, that the theory is revealed. After setting out Locke’s theory of solidity and cohesion, the paper examines Leibniz’s response to Locke in the New Essays. It then proceeds to the mechanical theory of conspiring motions developed in the Hartsoeker correspondence. The final section of the paper poses three problems for Leibniz’s theory – explanatory, empirical, and conceptual.     

THE NATURALIZATION OF SCRIPTURAL REASON IN SEVENTEENTH‐CENTURY EPISTEMOLOGY

Several scholars have claimed that the decline of revealed or Scriptural mysteries in the early Enlightenment was a consequence of the trajectories of Reformed theology in the sixteenth and seventeenth centuries. Reformed theology's fideistic stance, it is claimed, undermined earlier frameworks for relating reason to revealed mysteries; consequently, rationalism emerged as an alternative to such fideism in figures like the Cambridge Platonists. This article argues that Reformed theologians of the seventeenth century were not fideists but re‐affirmed Medieval claims about the eschatological concord of reason and revealed mysteries. Furthermore, the article suggests that early Enlightenment attitudes to religious mysteries owe more to innovations in Socinianism and Cambridge Platonism than to mainstream Reformed theology.     

Is Locke’s answer to Molyneux’s question inconsistent? Cross-modal recognition and the sight–recognition error

Abstract

Molyneux’s question asks whether someone born blind, who could distinguish cubes from spheres using his tactile sensation, could recognize those objects if he received his sight. Locke says no: the newly sighted person would fail to point to the cube and call it a cube. Locke never provided a complete explanation for his negative response, and there are concerns of inconsistency with other important aspects of his theory of ideas. These charges of inconsistency rest upon an unrecognized and unfounded assumption that seeing entails recognition. Locke’s negative answer to Molyneux’s question is consistent with his other philosophical commitments.     

Hume,Locke and consciousness

This is a reply to Donald Ainslie's discussion of Terence Penelhum's work on Hume, Locke and the nature of consciousness; although agree on many points about the differences between Locke and Hume, I take issue with Ainslie's views about the epistemic status Hume accords to introspective acts.     

Locke on testimony

ABSTRACT

There is good reason to regard John Locke’s treatment of testimony as perhaps the most important of the early modern period. It is sophisticated, well developed, pioneering, and seems to have given shape to the later debate that would occur between Hume and Reid. I attempt to do three things in this essay. First, I argue that Hume’s landmark treatment of testimony is an appropriation of that developed by Locke. Second, I suggest that understanding Locke’s view of testimony is of critical importance to Locke’s broader epistemology. Finally, I claim that Locke’s reflection on testimony is valuable in its own right in that it is not confined to isolating the conditions under which testimonial beliefs are warranted or justified. Locke’s interest is, rather, in a variety of doxastic states, or degrees of assent, that testimony may serve to ground.     

God,Truth and Mathematics in Nineteenth-century England

In his Essay Concerning Human Understanding, John Locke created a special epistemological category for mathematical and religious knowing. This category of knowledge was quickly brushed to the side in the French Enlightenment, but the English preserved it well into the nineteenth century. This article considers the ways that the neo-Lockian joining of mathematics and theology fundamentally affected both mathematical and theological thinking in the first half of the English nineteenth century. It argues that these developments set the stage for the post-Darwinian conflicts between science—including mathematics—and religion.     

Room for a view: on the metaphysical subject of personal identity

Sydney Shoemaker leads today’s “neo-Lockean” liberation of persons from the conservative animalist charge of “neo-Aristotelians” such as Eric Olson, according to whom persons are biological entities and who challenge all neo-Lockean views on grounds that abstracting from strictly physical, or bodily, criteria plays fast and loose with our identities. There is a fundamental mistake on both sides: a false dichotomy between bodily continuity versus psychological continuity theories of personal identity. Neo-Lockeans, like everyone else today who relies on Locke’s analysis of personal identity, including Derek Parfit, have either completely distorted or not understood Locke’s actual view. Shoemaker’s defense, which uses a “package deal” definition that relies on internal relations of synchronic and diachronic unity and employs the Ramsey–Lewis account to define personal identity, leaves far less room for psychological continuity views than for my own view, which, independently of its radical implications, is that (a) consciousness makes personal identity, and (b) in consciousness alone personal identity consists—which happens to be also Locke’s actual view. Moreover, the ubiquitous Fregean conception of borders and the so-called “ambiguity of is” collapse in the light of what Hintikka has called the “Frege trichotomy.” The Ramsey–Lewis account, due to the problematic way Shoemaker tries to bind the variables, makes it impossible for the neo-Lockean ala Shoemaker to fulfill the uniqueness clause required by all such Lewis style definitions; such attempts avoid circularity only at the expense of mistaking isomorphism with identity. Contrary to what virtually all philosophers writing on the topic assume, fission does not destroy personal identity. A proper analysis of public versus perspectival identification, derived using actual case studies from neuropsychiatry, provides the scientific, mathematical and logical frameworks for a new theory of self-reference, wherein “consciousness,” “self-consciousness,” and the “I,” can be precisely defined in terms of the subject and the subject-in-itself.
