In this volume, Rachel Giora explores how the salient meanings of words - the meanings that stand out as most prominent and accessible in our minds - shape how we think and how we speak. For Giora, salient meanings display interesting effects in both figurative and literal language. In both domains, speakers and writers creatively exploit the possibilities inherent in the fact that, while words have multiple meanings, some meanings are more accessible than others. Of the various meanings (...) weencode in our mental lexicon for a given word or expression, we ascribe greater cognitive priority to some over others. Interestingly, the most salient meaning is not always the literal meaning. Giora argues that it is cognitively prominent salient meanings, rather than literal meanings, that play the most important role in the comprehension and production of language. She shows that even though context begins to affect comprehension immediately, it does so without obstructing the early accessing of salient meanings. Thus, the meaning we first attend to is the salient word meaning, regardless of contextual bias. Knowledge of salient meanings turns out to play a major role, perhaps the most important role, in the process of using and understanding of language. Going beyond the familiar effects of literal meaning and context, the Graded Salience Hypothesis presents the most comprehensive explanation for how we use language for meaning. In this volume, Giora presents her new model for the first time in a book-length treatment, with original and illuminating perspectives that will be of interest to linguists, philosophers, psychologists, and all who want to know more about just how we understand what we mean.

The year 2009 marks the 400th anniversary of the publication of one of the most revolutionary scientific texts ever written. In this book, appropriately entitled, Astronomia nova, Johannes Kepler developed an astronomical theory which departs fundamentally from the systems of Ptolemy and Copernicus. One of the great innovations of this theory is its dependence on the science of optics. The declared goal of Kepler in his earlier publication, Paralipomena to Witelo whereby The Optical Part of Astronomy is Treated, was to (...) solve difficulties and expose illusions astronomers face when conducting astronomical observations with optical instruments. To avoid observational errors that had plagued the antiquated measuring techniques for calculating the apparent diameter and angular position of the luminaries, Kepler designed a novel device: the ecliptic instrument. In this paper we seek to shed light on the role optical instruments play in Kepler's scheme: they impose constraints on theory, but at the same time render astronomical knowledge secure. To get a comprehensive grasp of Kepler's astonishing achievements it is required to widen the approach to his writings and study Kepler not only as a mathematico-physical astronomer, but also as a designer of instruments and a practicing observer.

It is ironic that the prototype of the oscilloscope--for that is what Hertz's apparatus amounted to--should be instrumental in demonstrating that cathode rays have no closer relation to electricity than has light produced by an electric lamp. Indeed, Hertz argued that since "cathode rays are electrically indifferent,... the phenomenon most nearly allied to them is light.".

SummaryThis paper is an account of Kepler's explicit awareness of the problem of experimental error. As a study of the Astronomia nova shows, Kepler exploited his awareness of the occurrences of experimental errors to guide him to the right conclusion. Errors were thus employed, so to speak, perhaps for the first time, to bring about a major physical discovery: Kepler's laws of planetary motion. ‘Know then’, to use Kepler's own words, ‘that errors show us the way to truth.’ With a (...) survey of Kepler's revolutionary contribution to optics, the paper demonstrates that Kepler's awareness of the problem of experimental error extended beyond discrepancies between calculations and observations to types of error which pertain to observations and instruments. It emerges that Kepler's belief in the unity of knowledge and physical realism, facilitated—indeed created—the right philosophical posture for comprehending the problem of error in an entirely novel way.

Normal meiosis consists of a single round of DNA replication followed by two nuclear divisions. In the 1st division the chromosomes segregate reductionally whereas in the 2nd division they segregate equationally (as they do in mitosis). In certain yeast mutants, a single‐division meiosis takes place, in which some chromosomes segregate reductionally while others divide equationally. This autonomous segregation behaviour of individual chromosomes on a common spindle is determined by the centromeres they carry. The relationship between reductional segregation of a pair (...) of chromosomes and their earlier recombinational history is also discussed. (shrink)

Findings from two experiments argue in favor of the superiority of default, preferred interpretations over non-default less favored counterparts, outshining degree of non-salience, non-literalness, contextual strength, and negation. They show that, outside of a specific context, the default interpretation of specific negative constructions is a non-salient interpretation 1; their non-default interpretation is a salience-based alternative. In contrast, the default interpretation of the affirmative counterparts is a salience-based interpretation ; their non-default interpretation is a non-salient alternative. When in equally strongly supportive (...) contexts, default yet non-salient negative sarcasm is processed faster than non-default, non-salient yet affirmative sarcasm and faster than non-default yet salience-based negativ..

We call attention to the historical fact that the meaning of symmetry in antiquity—as it appears in Vitruvius’s De architectura—is entirely different from the modern concept. This leads us to the question, what is the evidence for the changes in the meaning of the term symmetry, and what were the different meanings attached to it? We show that the meaning of the term in an aesthetic sense gradually shifted in the context of architecture before the image of the balance was (...) attached to the term in the middle of the 18th century and well before the first modern scientific usage by Legendre in 1794.Keywords: Symmetry; Vitruvius; Claude Perrault; Charles-Louis de Secondat Baron de Montesquieu; Balance in architecture.

The term “analogy” stands for a variety of methodological practices all related in one way or another to the idea of proportionality. We claim that in his first substantial contribution to electromagnetism James Clerk Maxwell developed a methodology of analogy which was completely new at the time or, to borrow John North’s expression, Maxwell’s methodology was a “newly contrived analogue”. In his initial response to Michael Faraday’s experimental researches in electromagnetism, Maxwell did not seek an analogy with some physical system (...) in a domain different from electromagnetism as advocated by William Thomson; rather, he constructed an entirely artificial one to suit his needs. Following North, we claim that the modification which Maxwell introduced to the methodology of analogy has not been properly appreciated. In view of our examination of the evidence, we argue that Maxwell gave a new meaning to analogy; in fact, it comes close to modeling in current usage. (shrink)

This paper is concerned with the problem of experimental error. The prevalent view that experimental errors can be dismissed as a tiresome but trivial blemish on the method of experimentation is criticized. It is stressed that the occurrence of errors in experiments constitutes a permanent feature of the attempt to test theories in the physical world, and this feature deserves proper attention. It is suggested that a classification of types of experimental error may be useful as a heuristic device in (...) studying the nature of these errors. However, the standard classification of systematic and random errors is mathematically based does not focus on the causes of the errors, their origins, or the contexts in which they arise. A new typology of experimental errors is therefore proposed whose criterion is epistemological. This typology reflects the various stages that can be discerned in the execution of an experiment, each stage constituting a category of a certain type of experimental error. The proposed classification consists of four categories which are illustrated by historical cases. (shrink)

Chakravarthi Ram-Prasad offers illuminating new perspectives on contemporary phenomenological theories of body and subjectivity, based on studies of diverse classical Indian texts. He argues for a 'phenomenological ecology' of bodily subjectivity in health, gender, contemplation, and lovemaking.

This article discusses George Orwell’s attitude to Zionism and the Palestine question, a controversial and emotional subject in left-wing circles in his time and since. There have been a number of studies on Orwell’s attitude to Jews and anti-Semitism and some of these have touched upon Orwell’s approach to Zionism. However, his stance on the Palestine question specifically deserves further exposition. This is so, not least because on this subject too Orwell’s views—largely anti-Zionist—differed from the prevailing, passionate beliefs of most (...) left-wing intellectuals of his time, including some of his closest friends and political allies. Furthermore, Orwell’s views were expressed at a time when the Palestine conflict peaked during the last decade of the British Mandate with results which resound to this day. (shrink)

Sometimes, there are reasons for which we believe, intend, resent, decide, and so on: these reasons are the “bases” of the latter, and the explanatory relation between these bases and the latter is what I will call “the basing relation.” What kind of explanatory relation is this? Dispositionalists claim that the basing relation consists in the agent’s manifesting a disposition to respond to those bases by having the belief, intention, resentment, and so on, in question. Representationalists claim that the basing (...) relation consists in the agent’s representing the bases as justifying the belief, intention, resentment, and so on, in question. This article shows that an adequate account of the basing relation requires a particular refinement and combination of these two views. On the hybrid account defended here, the basing relation involves a disposition exercise that is individuated by the agent’s object-involving de se representation of that very exercise as justifying.

Four experiments and 2 corpus-based studies demonstrate that negation is a determinant factor affecting novel nonliteral utterance-interpretation by default. For a nonliteral utterance-interpretation to be favored by default, utterances should be potentially ambiguous between literal and nonliteral interpretations. They should therefore be (a) unfamiliar, (b) free of semantic anomaly or any kind of internal incongruity, and (c) unbiased by contextual information. Experiments 1–3 demonstrate that negative utterances, meeting these 3 conditions, were interpreted metaphorically (This is not a safe) or sarcastically (...) (Ambitious she is not) when presented in isolation and were therefore processed faster in contexts strongly biasing them toward their nonliteral than toward their (equally biased) literal interpretation. Experiment 4 reduces the possibility that it is structural markedness on its own that induces nonliteralness. Two corpus-based studies provide corroborating evidence, supporting the view of negation as an operator generating nonliteral interpretations by default. (shrink)

The claim that Galileo Galilei transformed the spyglass into an astronomical instrument has never been disputed and is considered a historical fact. However, the question what was the procedure which Galileo followed is moot, for he did not disclose his research method. On the traditional view, Galileo was guided by experience, more precisely, systematized experience, which was current among northern Italian artisans and men of science. In other words, it was a trial-and-error procedure—no theory was involved. A scientific analysis of (...) the optical properties of Galileo’s first improved spyglass shows that his procedure could not have been an informed extension of the traditional optics of spectacles. We argue that most likely Galileo realized that the objective and the eyepiece form a system and proceeded accordingly. (shrink)

In his recent Knowledge and its Limits, Timothy Williamson argues that no non-trivial mental state is such that being in that state suffices for one to be in a position to know that one is in it. In short, there are no “luminous” mental states. His argument depends on a “safety” requirement on knowledge, that one’s confident belief could not easily have been wrong if it is to count as knowledge. We argue that the safety requirement is ambiguous; on one (...) interpretation it is obviously true but useless to his argument, and on the other interpretation it is false. (shrink)

A skeptic claims that I do not have knowledge of the external world. It has been thought that the skeptic reaches this conclusion because she employs unusually stringent standards for knowledge. But the skeptic does not employ unusually high standards for knowledge. Rather, she employs unusually restrictive standards of evidence. Thus, her claim that we lack knowledge of the external world is supported by considerations that would equally support the claim that we lack evidence for our beliefs about the external (...) world. These considerations do not threaten the truth of our ordinary attributions of evidence, however, for such attributions are context-sensitive in their semantics. It is argued that this solution to the problem of the external world enjoys all of the benefits, and suffers none of the problems, of other solutions to the problem of the external world. (shrink)

What is the epistemological value of perceptual experience? In his recently influential paper, “The Skeptic and the Dogmatist”1, James Pryor develops a seemingly plausible answer to this question. Pryor’s answer comprises the following three theses: (F) “Our perceptual justification for beliefs about our surroundings is always defeasible – there are always possible improvements in our epistemic state which would no longer support those beliefs.” (517) (PK) “This justification that you get merely by having an experience as of p can sometimes (...) suffice to give you knowledge that p is the case.” (520) (D) “When it perceptually seems to you as if p is the case, you have a kind of justification for believing p that does not presuppose or rest on your justification for anything else, which could be cited in argument (even an ampliative argument) for p. To have this justification for believing p, you need only have an experience that represents p as being the case. No further awareness or reflection or background beliefs are required.” (519) Let’s use the phrase “fallibilist dogmatism” to refer to the conjunction of (F), (PK), and (D).2 Pryor does not argue for either (F) or (PK) in his paper; he simply shares the widespread and plausible assumption that (F) and (PK) are both true. But the conjunction of (F) and (PK) implies that we can have knowledge on the basis of defeasible justification. And this view leads to paradox. Consider the following individually plausible but jointly incompatible statements. (shrink)

The Optimal Innovation Hypothesis, following from the Graded Salience Hypothesis, is being reviewed and revisited. The attempt is to expand the notion of Optimal Innovation to allow it to apply to both stimuli’s coded meanings as well as their noncoded, constructed interpretations. According to the Optimal Innovation Hypothesis, Optimal Innovations, when devised, will be more pleasing than nonoptimally innovative counterparts. Unlike such competitors, Optimal Innovations deautomatize familiar coded alternatives, which invoke unconditional responses alongside novel but distinct ones, allowing both responses (...) to interact. Conversely, the Revised Optimal Innovation Hypothesis, introduced and tested here, follows from the Defaultness Hypothesis. It posits that both default lexicalized meanings and default constructed interpretations might be qualifiable for Optimal Innovation once they are deautomatized by nondefault, context-dependent counterparts. Such nondefault Optimal Innovations will be pleasing, more pleasing than default and nondefault counterparts not qualifiable for Optimal Innovation. Results of two experiments support the Revised Optimal Innovation Hypothesis, while further corroborating the Defaultness Hypothesis. (shrink)

In budding yeast, commitment to meiosis is attained when meiotic cells cannot return to the mitotic cell cycle even if the triggering cue (nutrients deprivation) is withdrawn. Commitment is arrived at gradually, and different aspects of meiosis may be committed at different times. Cells become fully committed to meiosis at the end of Prophase I, long after DNA replication and just before the first meiotic division (MI). Whole‐genome gene expression analysis has shown that committed cells have a distinct and rapid (...) response to nutrients, and are not simply insulated from environmental signals. Thus becoming committed to meiosis is an active process. The cellular event most likely to be associated with commitment to meiosis is the separation of the duplicated spindle‐pole bodies (SPBs) and the formation of the spindle. Commitment to the mitotic cell cycle is also associated with the separation of SPBs, although it occurs in G1, before DNA replication. (shrink)

(NEG) is widely accepted both by internalist and by externalists. In fact, there have been very few opponents of (NEG). Timothy Williamson (e.g., 2000) rejects (NEG), for reasons that have by now received a great deal of scrutiny.2 John McDowell also rejects (NEG), but his reasons have not received the scrutiny they deserve. This is in large part because those reasons have not been well understood. We believe that McDowell’s challenge to (NEG) is important, worthy of fair assessment, and maybe (...) even correct. In this paper, we explain McDowell’s challenge to (NEG), and also explain how McDowell can address a seemingly fatal objection to his view. (shrink)

The attempt to narrow the general discourse of the problem of error and to focus it on the specific problem of experimental error may be approached from different directions. One possibility is to establish a focusing process from the standpoint of history; such an approach requires a careful scrutiny of the history of science with a view to identifying the juncture when the problem of experimental error was properly understood and accounted for. In a study of this kind one would (...) have to examine the evolution of the method of experimentation and related topics so that clear criteria would underlie the analysis. (shrink)

Summary In his Theoremata de lumine, et umbre (1521), Francesco Maurolyco (1494–1575) discussed, inter alia, the problem of the pinhole camera. Maurolyco outlined a framework based on Euclidean geometry in which he applied the rectilinear propagation of light to the casting of shadow on a screen behind a pinhole. We limit our discussion to the problem of how the image behind an aperture is formed, and follow the way Maurolyco combined theory with instrument to solve the problem of the projection (...) of light through small apertures. We show that Maurolyco not only reformed the classical sources which, he thought, were no longer the authoritative code of textual knowledge, but also established with the dioptra a novel linkage of method, theory, and instrument. He thereby demonstrated the importance of optics to the science of astronomy. (shrink)

Susanna Schellenberg develops a unified account—“capacitism”—of perceptual content, phenomenology, and epistemic force. In this paper, I raise questions about her arguments for a capacitist account of evidential force, and then challenge her claim that such an account, even if correct, demands that our evidence be less than fully transparent to us.

In Fear of Knowledge, Paul Boghossian argues against various forms of epistemic relativism. In this paper, I criticize Boghossian’s arguments against a particular variety of relativism. I then argue in favor of a thesis that is very similar to this variety of relativism.

Wittgenstein’s On Certainty is sometimes read as providing a response to the skeptical puzzle from closure, according to which our commitment to the trustworthiness of our evidence is not itself evidentially grounded. In this paper, I argue both that this standard reading of Wittgenstein is incorrect, and that a more accurate reading of Wittgenstein provides us with a more plausible solution to the Closure Puzzle.
