In this paper, I will argue that Locke is a substance dualist in the general sense, in that he holds that there are, independent of our classificatory schema, two distinct kinds of substances: wholly material ones and wholly immaterial ones. On Locke’s view, the difference between the two lies in whether they are solid or not, thereby differentiating him from Descartes. My way of establishing Locke as a general substance dualist is to be as minimally committal as possible at the (...) outset, especially with respect to the classic debates on Locke’s positions in this domain, including those concerning substrata, real essences, and the like. Nonetheless, I show that minimal commitments about Locke’s primary/secondary quality distinction are sufficient to derive some substantive conclusions about his positions on these issues, as well as that he is a general substance dualist.

La relación entre patrimonio y derechos políticos en la obra de John Locke ha sido ampliamente discutida. Por un lado, se encuentran posiciones como las de Kendall y Tully que atribuyen un carácter democrático a la concepción lockeana sobre la sociedad civil. Por otro, interpretaciones como las de Ashcraft que le asignan un sesgo revolucionario e igualitario, próximo a la concepción de los Levellers. Sin embargo, a la luz de una serie de documentos, es posible discutir estas interpretaciones, como ya (...) lo han hecho diversos intérpretes parcialmente. Se mostrará aquí que Locke supone que la discusión parlamentaria compete a quienes, representando a los diferentes sectores productivos, discuten la promoción de sus actividades y que los trabajadores, al no disponer de la formación necesaria para la discusión sobre los asuntos públicos, no son considerados para participar del ejercicio parlamentario sino sólo de una resistencia excepcional.

Al final del Libro II del An Essay Concerning Human Understanding, Locke manifiesta que «hay una relación tan íntima entre las ideas y las palabras […] que es imposible hablar clara y distintamente de nuestro conocimiento, que consiste completamente en proposiciones, sin considerar, primero, la naturaleza, uso y significación del lenguaje». De varias y diversas maneras Locke insiste en la tesis que ‘las palabras significan ideas’. En este ensayo me propongo: 1º resumir la teoría general del lenguaje de Locke; 2º (...) revisar algunas objeciones regulares a esta teoría, y 3º intentar una explicación de lo que Locke quiere decir cuando enuncia que ‘las palabras significan ideas’. Con respecto a este punto mostraré, apoyando la interpretación de E. J. Ashworth, que en su tesis semántica Locke usa el vocablo ‘significar’ (‘signifying’) no del modo como es usado por los teóricos contemporáneos del siglo XX, sino en el sentido que algunos escolásticos usaron el término ‘significare’. At the very end of Book II of ‘An Essay Concerning Human Understanding’, Locke finds out «that there is so close a connexion between Ideas and Words […] that it is impossible to speak clearly and distinctly of our Knowledge, which all consists in Propositions, without considering first the Nature, Use, and Signification of Language». In various and diverse ways Locke defends the thesis that ‘Words signify Ideas’. My aim in this paper is first, to sum up Locke’s general theory of Language; secondly, to revisit some regular objections concerning this theory, and thirdly, to intend an explanation of what Locke means when he points out that ‘Words signify ideas’. In regard to this point, I shall hold up E. J. Ashworth’s interpretation to show that Locke semantic thesis involves the use of the verb ‘to signify’ (‘signifying’) not in the manner that it is used by contemporary theorists of the twentieth century, but in the sense that some scholastics used the term ‘significare’.

In the Essay, Locke refers to the ordinary-sized natural things as ‘particular sorts of Substances’ (2.23), whereas the ‘three sorts of Substances’ (2.27) are more metaphysically laden sorts: God, finite spirits, and fundamental material particles. He posits the much-contested ‘substratum’ in each particular sort of substance but not any of the three sorts. It should also be noted that his list of the particular sorts includes ‘men’. In regard to this nobler sort, he refers to a further classification – viz., (...) ‘the Substance of spirit’ and ‘the Substance of the body’ – only in terms of their nominal essence. A naturalistic, nominalist approach is deeply entrenched in his account of the human-related sorts as well. In this chapter, I shall explore how Locke develops a theory of substance in the Essay that is less metaphysical, more naturalistic, and epistemically humbler than those of his rationalist contemporaries.

In the Essay Locke argues abstract ideas within the framework of the descriptivist theory of reference. For him, abstract ideas are, in many cases, conceptual ideas that play the role of “descriptions” or “descriptive contents,” determining general terms’ referents. In contrast, in the introduction of the Principles, Berkeley denies Lockean abstract ideas adamantly from an imagistic point of view, and he offers his own theory of reference seemingly consisting of referring expressions and their referents alone. However, interestingly, he mentions a (...) general term’s “definition” and suggests that it determines the scope of the term’s referents. For example, he takes up the definition of a triangle as “a plain Surface comprehended by three right Lines” and suggests that just as Locke’s general idea of a triangle does, the definition determines the referents of the general term “triangle.” His definition reminds us of the fact that as Descartes grasps the content of the general idea of a triangle as “a figure enclosed by three lines,” so Locke grasps the abstract idea of a triangle as “a Figure including a Space between three Lines,” and so on. That is, since Berkeley is an imagist, he does not acknowledge Locke’s conceptual abstract ideas as “ideas,” but although he verbally denies “abstract ideas,” his theory of reference also actually has the same descriptivist framework consisting of referring expressions, their descriptive contents, and their referents. Thus, we understand the real reason why Berkeley’s criticism of Locke seems beside the point. (shrink)

What sort of property did Locke take colors to be? He is sometimes portrayed as holding that colors are wholly subjective. More often he is thought to identify colors with dispositions—powers that bodies have to produce certain ideas in us. Many interpreters find two or more incompatible strands in his account of color, and so are led to distinguish an “official,” prevailing view from the conflicting remarks into which he occasionally lapses. Many who see him as officially holding that colors (...) are dispositions concede that some of his remarks imply that colors are in us rather than in objects. After raising some difficulties for these readings, I offer an alternative. I will argue that Locke takes colors to be relational, but not dispositional, properties of the objects around us. On his view, an object is red if and only if it is actually causing a certain sensation in some observer. (shrink)

Locke seems to hold that we have knowledge of the existence of external objects through sensation. Two problems face Locke's account. The first problem concerns the logical form of knowledge of real existence. Locke defines knowledge as the perception of the agreement or disagreement between ideas. However, perceiving agreements between ideas seems to yield knowledge only of analytic truths, not propositions about existence. The second problem concerns the epistemic status of sensitive knowledge: How could the senses yield certain knowledge? This (...) essay argues that the key to solving both problems is Locke's claim that simple ideas are all real, adequate, and true. This explains why, on Locke's view, we have certain knowledge through the senses. It also explains how sensitive knowledge can consist in perceiving an agreement between ideas: perceived agreements among simple ideas of sensation are guaranteed to track relations that obtain among really existing things.

A great deal of the criticism directed at Locke's theory of abstract ideas assumes that a Lockean abstract idea is a special kind of idea which by its very nature either represents many diverse particulars or represents separately things that cannot exist in separation. This interpretation of Locke has been challenged by scholars such as Kenneth Winkler and Michael Ayers who regard it as uncharitable in light of the obvious problems faced by this theory of abstraction. Winkler and Ayers argue (...) that Locke instead held that to have an abstract idea is to attend selectively to some portion of the content of a particular idea. On this view, to have an abstract idea is not to have a special kind of idea but to have an ordinary idea in a special way. Ayers argues that Locke inherited this theory from Arnauld. I argue that the case made by Ayers for the attribution of the extrinsic theory to Locke rests on a misinterpretation of Arnauld. In fact, both Locke and Arnauld regard selective attention as part of a process whereby a new kind of idea is constructed. (shrink)

Descartes held that practicing mathematics was important for developing the mental faculties necessary for science and a virtuous life. Otherwise, he maintained that the proper uses of mathematics were extremely limited. This article discusses his reasons which include a theory of education, the metaphysics of matter, and a psychologistic theory of deductive reasoning. It is argued that these reasons cohere with his system of philosophy.

This paper takes up two questions regarding Locke’s doctrine of suspension. First, what motivates suspension? Second, what are the conditions under which we are motivated to suspend? In response to the first question, I argue that suspension is motivated by the desire to avoid the possible future evils that might result from acting precipitately upon some desire without suspending. In response to the second question, I argue against the common assumption that the desire motivating suspension must be an agent’s most (...) pressing desire. (shrink)

This paper is divided into two main sections. The first articulates what I believe Strawson's position to be. I contrast Strawson's usage of 'physicalism' with the mainstream use. I then explain why I think that Strawson's position is one of property dualism and substance monism. In doing this, I outline his view and Locke's view on the nature of substance. I argue that they are similar in many respects and thus it is no surprise that Strawson actually holds a view (...) on the mind much like one plausible interpretation of Locke's position. Strawson's use of terminology cloaks this fact and he does not himself explicitly recognize it in his paper. In the second section, I outline some of Strawson's assumptions that he uses in arguing for his position. I comment on the plausibility of his position concerning the relation of the mind to the body compared with mainstream physicalism and various forms of dualism. Before embarking on the two main sections, in the remainder of this introduction, I very briefly sketch Strawson's view. (shrink)

Discussions of John Locke’s theory of causation tend, understandably, to focus on the related notion of power and in particular the dialectic with David Hume. But Locke faces a very different threat, one that is internal to his view. For he argues both that causation is a relation and that relations are not real. The obvious conclusion is intolerable. And yet the premises, I argue, are unassailable. Building on an interpretation of Locke’s treatment of relations I have developed elsewhere, I (...) show how Locke can at once speak meaningfully of causation and deny its mind-independent existence.

A confluence of scholarly interest has resulted in a revival of Thomistic scholarship across the world. Several areas in the investigation of St. Thomas Aquinas, however, remain under-explored. This volume contributes to two of these neglected areas. First, the volume evaluates the contemporary relevance of St. Thomas's views for the philosophy and practice of education. The second area explored involves the intersections of the Angelic Doctor’s thought and the numerous cultures and intellectual traditions of the East. Contributors to this section (...) examine the reception, creative appropriation, and various points of convergence between St. Thomas and the East. (shrink)

One of the features of John Locke’s moral philosophy is the idea that morality is based on our beliefs concerning the future good. In An Essay Concerning Human Understanding II, xxi, §70, Locke argues that we have to decide between the probability of afterlife and our present temptations. In itself, this kind of decision model is not rare in Early Modern philosophy. Blaise Pascal’s Wager is a famous example of a similar idea of balancing between available options which Marcelo Dascal (...) has discussed in his important 2005 article “The Balance of Reason”. -/- Leibniz, however, was not always satisfied with this kind of simple balancing. In his commentary to Locke’s Essay, Nouveaux essais sur l’entendement humain, II, xxi, §66, he presented an alternative model which is based on an idea of plural, mutually conflicting inclinations. This kind of model, called as vectorial theory of rational decision by Simo Knuuttila, fits well with Leibniz’s theory of the soul where volitions are formed as a kind of compromise between different inclinations to different goods. -/- I will present these two models and show how they illustrate the practical rationality of Locke and Leibniz and how their moral philosophies differ, although being similar in certain respects. The topics include Leibniz’s criticism of Lockean hedonism and the discussion of akratic behaviour in II, xxi of Essay and Nouveaux essais. (shrink)

São variadas as interpretações da crítica berkeleyana às idéias abstratas, mas elas costumam concordar na tese de que essa crítica gira em torno da natureza das “idéias”. Isto é, se “idéia” for o mesmo que “imagem”, então a abstração lockeana é impossível, caso contrário, não. Neste artigo eu procuro mostrar que essa crítica não depende de idéia ser ou não uma imagem e que Locke está parcialmente consciente do problema levantado por Berkeley. Locke's general triangle and Berkeley's partial considerationThere are (...) many different interpretations of Berkeley's attack on abstract ideas, but they usually agree in sustaining that this attack depends on the nature of "ideas". That is, if "idea" is the same as "image", then lockean abstraction is impossible, but otherwise not. In this paper I show that this attack on abstract ideas does not depend on the issue concerning the nature of idea as image, and that Locke is partially aware of the problem raised by Berkeley.
