The phenomenon of entrepreneurship has attracted researchers from a variety of disciplines and a diverse number of analytical approaches. Currently, there is a considerable amount of confusion and a variety of conflicting theories which are being used interchangeably and ambiguously. In this important new book, the authors argue that there are analytically distinct forms of entrepreneurship, each of them having an individual logic of their own. They highlight the role of individual economic agents with endowments of new knowledge or new (...) combinations of old knowledge as entrepreneurs, and thus identify them as dynamic factors in the knowledge economy. Overall, this book not only provides a contemporary overview of current research in the field, but also summarizes the policy conclusions that can be drawn from current research. (shrink)

In what follows I propose to consider the relevance of Plato's early claim that his Forms are explanatory to the structure of, and several of the main arguments of, the Parmenides. The first section of the paper looks into some implications of separate existence, exploring connections between the criticism of separation and the conception of Forms as explanatory principles. I focus attention on what the Forms do not explain, and suggest that the burden of much of Parmenides’ criticism centers on (...) that question. Part two deals with Plato's evidently changing stance on the issue of explaining the Forms themselves. The third section takes up passages from the Parmenides in support of the view that Plato came to believe that his Forms stood in need of the same sort of explanation as he had originally thought was required for sensory particulars. The discussion is largely exploratory, and the connections adumbrated are intended as guidelines for further investigation. (shrink)

A familiar tradition in Plato scholarship has it that self-predication is one of the most important issues to be settled in an attempt to understand Plato‘s metaphysical views. Perhaps only latent in the initial formulations of the theory of Forms, the problem becomes manifest in the Parmenides, especially in the Third Man Argument where the assumption that a Form can have the property that it is helps to generate a vicious regress destructive of the notion of a single Form over (...) many particulars.

I believe that Tom is the proud father of a baby boy. Why do I think his child is a boy? A natural answer might be that I remember that his name is ‘Owen’ which is usually a boy’s name. Here I’ve given information that might be part of a causal explanation of my believing that Tom’s baby is a boy. I do have such a memory and it is largely what sustains my conviction. But I haven’t given you just (...) any causally relevant information, I’ve given my grounds for my belief. I’ve given reasons that might justify me in supposing that Tom’s baby is a boy. Less naturally, the question might be taken as a request for a broader causal explanation of my holding this belief. Appropriate answers might cite all manner of facts concerning the evolution of the human race, why I chose to pursue philosophy and hence came to know Tom, the mechanisms of email transmission, the firing of various neurons, the circumstances of concept formation as a result of which I’m able to grasp the thought that Tom’s baby is a boy, and so on. It is an interesting question what distinguishes the narrower set of answers that I first suggested. I won’t pursue that here. I assume you have a good enough sense of the distinction I’m drawing. We might call the narrower set of answers justifying reasons, the kind of reasons I might cite in justifying my belief. Answers of the first sort are clearly relevant to epistemological evaluation. In assessing whether you know p or are rational in believing it to the degree you do, I will naturally want to consider what reasons you have for your belief. In deliberating myself about whether to believe p, in seeking an answer to the question of whether p, I will naturally consider what reasons or grounds I have to suppose that p. But what I want to focus on here is how explanations of the broader sort bear on such questions as whether to believe p. From a third-person perspective we can ask, ‘In assessing the epistemic status of S’s belief that p, what is the relevance of causal information that lies outside of the realm of justifying reasons?’ From the first-person standpoint we can ask ‘In seeking to answer whether p, how should such causal information affect my deliberations?’ At first it might seem that such broader causal information could have little relevance if any. Like any belief my belief that p can be traced back to innumerable causes from far and wide.. (shrink)

This paper strives to characterize the relation between accent placement and discourse in terms of independent constraints operating at the interface between syntax and interpretation. The Givenness Constraint requires un-F-marked constituents to be given. Key here is our definition of givenness, which synthesizes insights from the literature on the semantics of focus with older views on information structure. AvoidF requires speakers to economize on F-marking. A third constraint requires a subset of F-markers to dominate accents.The characteristic prominence patterns of "novelty (...) focus" and "contrastive focus" both arise from a combination of the Givenness Constraint and AvoidF. Patterns of prominence in questions as well as in answers to questions are explained in terms of the constraints, thanks in part to the way in which the Givenness relation is defined. Head/argument asymmetries noted in the literature on Focus Projection are placed in the phonology-syntax interface, independent of discourse conditions. Deaccenting follows when AvoidF is ranked higher than constraint(s) governing head/argument asymmetries. (shrink)

Preanalytically, we are all scientific realists. But both philosophers and scientists become uncomfortable when forced into analysis. In the case of scientists, this discomfort often arises from practical difficulties in setting out a carefully described set of objects which adequately account for the phenomena with which they are concerned. This paper offers a set of representative examples of these difficulties for contemporary physicists. These examples challenge the traditional realist vision of mature scientific activity as struggling toward an ontologically well-defined world (...) picture. They challenge antirealist alternatives as well. (shrink)

(1) is an example of an adjectival comparative. In it, the adjective important is flanked by more and a comparative clause headed by than. This article is a survey of recent ideas about the interpretation of comparatives, including (i) the underlying semantics based on the idea of a threshold; (ii) the interpretation of comparative clauses that include quantifiers (brighter than on many other days); (iii) remarks on differentials such as much in (1) above: what they do in the comparative and (...) what they do elsewhere in the language; (iv) the relationship between comparatives and other Degree constructions (e.g. as important, too impor- tant); and (v) the types of phrases in which comparatives are found (adjective: tighter versus noun: more water). Given the nature and purpose of this essay, I have tried not to presuppose background in formal semantics and I have departed from standard practice in journal articles by, as much as possible, not interrupting the flow with footnotes and references. There are two appendices. The first provides more analytical detail and there I do rely on formal techniques of natural language semantics. The second covers the sources for the ideas surveyed here.

This paper argues for a treatment of belief as essentially sensitive to certain features of context. The first part gives an argument that we must take belief to be context-sensitive in the same way that assertion is, if we are to preserve appealing principles tying belief to sincere assertion. In particular, whether an agent counts as believing that p in a context depends on the space of alternative possibilities the agent is considering in that context. One and the same doxastic (...) state may amount to belief that p in one context but not another. The second part of the paper gives a formal treatment of doxastic states, according to which belief is context-sensitive along just these lines. The model is applied to characterize (but not to refute) skeptical arguments. (shrink)

In the formation of extended noun phrases, expressions are used that describe some dimension. Weight is described by each of the prenominal expressions in heavy rock, too much ballast, 2 lb rock, 2 lbs of rocks. The central claim of this paper is that the position of these types of expressions within the noun phrase limits the kinds of dimensions they may describe. The limitations have to do with whether or not the dimension tracks relevant part-whole relations. An analogy is (...) made between these constraints and the well-known constraints on thematic relations that are incurred by the position of a noun phrase in a clause. A proposal is made about the meanings of expressions like too much and 2 pounds which explains their common cross-categorial distribution and this informs the analysis of their use in noun phrases. A position is taken on the meaning of the count mass distinction which, in conjunction with the hypothesis about dimensions, explains asymmetries in the distribution of prenominal adjectives with count and mass nouns.

Parkinson's disease (PD) is characterized by the loss of the dopaminergic nigrostriatal pathway which has led to the successful development of drug therapies that replace or stimulate this network pharmacologically. Although these drugs work well in the early stages of the disease, over time they produce side effects along with less consistent clinical benefits to the person with Parkinson's (PwP). As such there has been much interest in repairing this pathway using transplants of dopamine neurons. This work which began 50 (...) years ago this September is still ongoing and has now moved to first in human trials using human pluripotent stem cell‐derived dopaminergic neurons. The results of these trials are eagerly awaited although proof of principle data has already come from trials using human fetal midbrain dopamine cell transplants. This data has shown that developing dopamine cells when transplanted in the brain of a PwP can survive long term with clinical benefits lasting decades and with restoration of normal dopaminergic innervation in the grafted striatum. In this article, we discuss the history of this field and how this has now led us to the recent stem cell trials for PwP. (shrink)

This contribution to the adaptationism debate elaborates the nature of constraints and their importance in evolutionary explanation and argues that the adaptationism debate should be limited to the issue of how to privilege causes in evolutionary explanation. I argue that adaptationist explanations are deeply conceptually dependent on developmental constraints, and explanations that appeal to constraints are dependant on the results of natural selection. I suggest these explanations should be integrated into the framework of historical causal explanation. Each strategy explicitly appeals (...) to some aspect of the evolutionary process, while implicitly appealing to others. Thus, adaptationists and anti-adaptationists can offer complementary causal explanations of the same explanandum. This eliminates much of the adaptationism debate and explains why its adversaries regularly agree with each other more than they would like. The adaptationism issue that remains is a species of the general issue of how to privilege causes in explanation. I show how a proposed solution to this general problem might be brought to bear on evolutionary explanations, and investigate some difficulties that might arise due to the nature of the evolutionary process.

Contra Michael Walzer and Jeff McMahan, neither classical just war theory nor the contemporary rules of war require or support any notion of combatant moral equality. Nations rightly accept prohibitions against punishing enemy combatants without recognizing any legal or moral right of aggressors to kill. The notion of combatant moral equality has real import only in our interpersonal -- and intrapersonal -- attitudes, since the notion effectively preempts any ground for conscientious objection. Walzer is criticized for over-emphasizing our collective responses (...) to war conduct and slighting our personal, extra-political responses. (shrink)

Epistemic systems are social processes generating judgments of truth and falsity. I outline a mathematical theory of epistemic systems that applies widely. Areas of application include pure science, torture, police forensics, espionage, auditing, clinical medical testing, democratic procedure, and the market economy. I examine torture and police forensics in relative detail. This paper is an exercise in comparative institutional epistemics, which considers how the institutions of an epistemic system influence its performance as measured by such things as error rates and (...) the volume of judgments generated.

The use of composite outcomes is becoming widespread in clinical trials. By combining individual outcome measures into a composite, researchers claim a composite can increase statistical precision and trial efficiency, expediting the trial by reducing sample size and cost, and consequently enabling researchers to answer questions that could not otherwise be answered. Another rationale given for using a composite is that it provides a measure of the net effect of the intervention that is more patient-relevant than any single outcome measure. (...) Critics, on the other hand, argue that the use of composites threatens the scientific objectivity of the trial by introducing new risks, and that in practice components are inconsistently defined, unreasonably combined, and inadequately reported. Philosophical scrutiny can help shed light in these disagreements and disentangle ethical and epistemological issues of composites in clinical trials. I examine common use of composites in cardiovascular trials, and show how composite results can be problematic, even misleading, if the proper range of scientific decisions and their consequences are ignored when judging the composite. Philosophies of science that are principled on normative versions of the argument from inductive risk can help explicate issues with composites. I conclude by suggesting ways of remedying composite issues in clinical trials. (shrink)

Can we lose our concepts? A case like ‘phlogiston’ invites a positive answer, though the sensefulness of ‘There is no phlogiston’ gives us pause. But concepts are about more than just ‘extension-determination’; hence Diamond’s examination of putative loss of moral concepts does point to a possible phenomenon. That loss of concepts could be regrettable seems to make room for the thought that having certain concepts could likewise be regrettable. Anscombe’s critique of the concept of ‘moral obligation’ appears to be suggesting (...) this, but it presents a dilemma: do the relevant words and phrases have a ‘special sense’ or are they senseless? Either answer is acceptable, I argue; roughly speaking, confused use makes for confused meaning. Objections coming from a certain picture of the autonomy of grammar fail. A diagnosis of ‘confused use’ can lead naturally to our seeing speakers as caught up in a species of dishonesty or inauthenticity, and also to our referring to the ‘kind of nonsense’ being talked. This last phrase seems to fall foul of the sort of consideration Diamond raised when discussing nonsense in the Tractatus. However, the case of ‘secondary sense’ shows us how we can understand this reference to ‘kinds of nonsense’. (shrink)

There are, broadly, three sorts of account of intrinsicality: ‘self-sufficiency’, ‘essentiality’ and ‘pure qualitativeness’. I argue for the last of these, and urge that we take intrinsic properties of concrete objects to be all and only those shared by actual or possible duplicates, which only differ extrinsically. This approach gains support from Francescotti’s approach: defining ‘intrinsic’ in contradistinction to extrinsic properties which ‘consist in’ relations which rule out intrinsicality. I answer Weatherson’s criticisms of Francescotti, but, to answer criticisms of my (...) own, I amend his account, proposing that possession of an extrinsic property consists in a relation to one or more actual or possible distinct concrete objects. Finally I indicate ways to avoid some apparent objections to this account. (shrink)

This book explores contemporary continental philosophy and aesthetics. It addresses the problem of post-Kantian reason in relation to the pathologies of experience, alienation, the transformative and ethical import of aesthetic experience, the relation between philosophy and social critique, and language as disclosure rather than correspondence.

Descartes’ distinction between infinite and indefinite is important for his philosophy, but poorly understood. Various commentators have offered conflicting interpretations of it; some have even questioned ist importance. In this paper I wish to investigate Descartes’ various discussions of the distinction and to use my investigation to shed light on the related question of the authority of the "Conversation with Burman". I believe that the distinction is treated differently in the "Conversation" than it is in the Cartesian corpus proper and (...) that the difference of treatment is paradigmatic of other differences between that work and the works which come from Descartes’ own hand. I divide my discussion into two parts: first, on the reliability of the "Conversation" and Ferdinand Alquié’s critique of it; and second, on the distinction between the infinite and indefinite.
