The paper advances the hypothesis that George Berkeley's philosophy does not overcome solipsism. In order to do this, it presents four difficulties on his arguments for other existences: (I) the argument about the existence of an external cause for sensitive ideas faces the difficulty of not eliminating the possibility that the mind itself is the cause of these ideas; (II) the argument present in the Dialogues to prove the existence of God is circular: it presupposes the existence of objects distinct (...) from the mind, however, the argument for the existence of these objects presupposes the existence of God; (III) the argument in favor of the existence of those objects, besides being related to the mentioned circularity, is developed without Berkeley presenting a clear notion of what these objects are; (IV) the argument for the existence of other minds, in what appears to be their most plausible interpretation – which states that it is possible to infer the existence of other minds from the observation of irregular, inconstant, and vicious actions in subjects –, faces the difficulty that, in a scenario where such actions do not exist, Berkeley loses the evidence for the existence of other minds.

This volume focuses on Berkeley's doctrine of signs. The 'doctrine of signs' refers to the use that Berkeley makes of a phenomenon that is central to a great deal of everyday discourse: one whereby certain perceivable entities are made to stand in for (as 'signs' of) something else. Things signified might be other perceivable entities or they might also be unperceivable notions - such as the meanings of words. From his earliest published work, A New Theory of Vision in 1710, (...) to those works written towards the end of life, including Alciphron in 1732, Berkeley is at pains to emphasise the crucial role that sign-usage, particularly (but not only) in language, plays in human life. Berkeley also connects sign-usage to our (human) relationship with God: an issue that was right of the heart of his philosophical project. The contributions in this volume explore the myriad ways that Berkeley built on such insights to better understand a range of philosophical issues - issues of epistemology, language, perception, mental representation, mathematics, science, and theology. The aim of this volume is to establish that the doctrine of signs can be seen as one of the unifying themes of Berkeley's philosophy. What's more, this theme is one which spans his whole philosophical corpus; not just his best-known works like the Principles and the Three Dialogues, but also his works on science, mathematics, and theology.

Both Reid and Berkeley reject ‘representationalism’, an epistemological position whereby we (mediately) perceive things in the world indirectly via ideas in our mind, on the grounds of anti-scepticism and common sense. My aim in this paper is to draw out the similarities between Reid and Berkeley's ‘anti-representationalist’ arguments, whilst also identifying the root of their disagreements on certain fundamental metaphysical issues. Reid famously rejects Berkeley's idealism, in which all that exists are ideas and minds, because it undermines the dictates of (...) common sense. Reid also charges Berkeley with not only accepting but furthering the progress of ‘the Way of Ideas’, a longstanding tradition which has drawn philosophy away from true science and common sense. From Berkeley's perspective, Reid is a ‘materialist’; that is, he dogmatically accepts that mind-independent things exist. I argue that these important differences can be explained by both thinkers’ construal of certain ‘philosophical prejudices’. Finally, I conclude that despite these differences, both ought to be characterised as ‘anti-representationalists’ in light of their shared epistemological concerns. (shrink)

Berkeleyan idealism, or ‘immaterialism,’ has had an enormous impact on the history of philosophy during the last three centuries. In recent years, Christian scholars have been especially active in exploring ways that Berkeley's thesis may be fruitfully applied to a variety of issues in philosophy and theology. This essay provides an overview of some of the ways Christian philosophers have deployed immaterialism to solve problems and generate insights in metaphysics, philosophy of mind, philosophy of science, philosophy of religion, and philosophical (...) theology.

Berkeley's immaterialism aims to undermine Descartes's skeptical arguments by denying that the connection between sensory perception and reality is contingent. However, this seems to undermine Berkeley's (alleged) defense of commonsense by failing to recognize the existence of objects not presently perceived by humans. I argue that this problem can be solved by means of two neglected Berkeleian doctrines: the status of the world as "a most coherent, instructive, and entertaining Discourse" which is 'spoken' by God (Siris, sect. 254) and the (...) nature of language as a public social practice. Together these doctrines entail that ordinary physical objects, including those that are not presently perceived, are a joint product of divine discursive activity and human interpretive activity.

Most philosophers have given up George Berkeley’s proof for the existence of God as a lost cause, for in it, Berkeley seems to conclude more than he actually shows. I defend the proof by showing that its conclusion is not the thesis that an infinite and perfect God exists, but rather the much weaker thesis that a very powerful God exists and that this God’s agency is pervasive in nature. This interpretation, I argue, is consistent with the texts. It is (...) also an important component of Berkeley’s philosophical project, which consists of launching many small arguments against his philosophical and theological opponents. (shrink)

Traditionally, religious doctrines and practices have been divided into two categories. Those that purport to be justified by natural reason alone are said to be part of natural religion, while those which purport to be justified only by appeal to supernatural revelation are said to be part of revealed religion. One of the central aims of Berkeley's philosophy is to understand and defend both the doctrines and the practices of both natural and revealed (Christian) religion. This chapter will provide a (...) survey of this aspect of Berkeley's thought. (shrink)

The representative theory of perception is one of the realist theories of perception which maintains we do not have direct access to the objects of perception; our ideas represent some objective objects in the world. In this paper, I will address the question about the representative nature of mental ideas from a Thomistic perspective. I will explore if some Thomists are entitled to claim that Aquinas’ theory of knowledge based on his metaphysics can provide a basis for resolving this issue. (...) I will argue that this question is wrong-headed and it should be replaced with the following question: If we assume the existence of a real world and that we are not under the influence of hallucination, how we can know that our ideas truly represent the world?

To the great puzzlement of his readers, Berkeley begins by arguing that nothing exists other than minds and ideas, but concludes by claiming to have defended the existence of bodies. How can Berkeley's idealism amount to such a defense? I introduce resources from Berkeley's philosophy of language, and especially his analysis of the discourse of physics, to defend a novel answer to this question. According to Berkeley, the technical terms of physics are meaningful despite failing to designate any reality; their (...) meaningfulness derives from the useful role they play in organizing and predicting our experience. I argue that Berkeleian bodies have the same status as these theoretical entities: they are mere 'quasi-entities' introduced by our ways of speaking and thinking in order to serve our practical purposes. Berkeley nevertheless considers this to be a defense of the existence of bodies because he endorses a radically deflationary semantics for 'exists.'. (shrink)

La filosofía inmaterialista de Berkeley ha sido muchas veces infravalorada por la mala comprensión de su propuesta ontológica, específicamente por la dificultad que presenta su concepto de idea. El propósito de este artículo es, entonces, esclarecer y explicar dicho concepto porque de ello depende entender correctamente la ontología y el inmaterialismo filosófico berkeleyano. Para realizar esto 1) mostraré algunos ejemplos de la mala comprensión que ha tenido la propuesta berkeleyana, debido principalmente a su concepto de idea; 2) rastrearé cómo se (...) fue conformando dicho concepto en las notas de juventud conocidas como _Comentarios Filosóficos_; 3) analizaré y explicaré el concepto de idea a partir de la obra publicada de los _Principios_ y los _Diálogos_.
