this book concerns the debates on the functions of "imagination" (phantasia, imaginatio) in the arousal of passions in the Aristotelian and post-Aristotelian traditions till the XVIIth Century. The simple fact that often a mental representation is followed by pleasure or sorrow and that these emotions can cause actions, became progressively part of a wider theory of animal and human behaviour. In the case of human behaviour, the "force of imagination" became a kind of general justification of all kind of anomic (...) and irregular behaviour and beliefs, including true paranormal conditions of the body. The book recapitulates the main evolution of this way of seeing passions - from Aristotle to Avicenna and his Latin followers - till the age of the authors who see the inner work of "imagination" as a constant danger for human reason, and imagination itself as faculty to control with care for its propension to be the "advocate" of the "inferior part of the soul", such as Gianfrancesco Pico, Juan Luis Vivés, Pierre Charron, Blaise Pascal and a large part of the French Augustinian Moral Philosophers.

ABSTRACT : On many accounts, Rule IV appears to be composed of two distinct texts, and this should be justified by the difference between the mathesis universalis and the Cartesian method. This article runs counter to the usual interpretation by showing that the discussion on mathematics in Rule IV has enabled the introduction of method constraining scientific research to operate on grounds of order and measurement. The mathesis universalis is not so much a science of higher mathematics as a universal (...) method by the means of which one can find truth. (shrink)

The main purpose of this article is, from a semiotic perspective, arguing for the recognizing of a semantic role of the imagination as a necessary condition to our linguistic experience, regarded as an essential feature of the relations of our thought with the world through signification processes ; processes centered in but not reducible to discourse. The text is divided into three parts. The first part presents the traditional position in philosophy and cognitive sciences that had barred until recent times (...) the possibility to investigate the semantic function performed by imagination, mainly due to the anti-psychologist arguments on which it is based. After that, I situate my perspective inside of the recent research panorama in philosophy and cognitive science. The second part presents the semiotic framework on the relation between thought, language, and world, conceived through the concepts of signification processes and sense-conditions. Within this framework, I introduce the concept of linguistic experience, characterizing semantic imagination as one of its sense-conditions. In the third part, several pieces of evidence for corroborating the semantic function of imagination are discussed. These pieces come from the fields of phenomena denoted as diagrammatic thought and counterfactual thought. Diagrammatic thought, briefly discussed, points out the semantic work of imagination in the semi-discursive sign systems constructed in mathematics, logic, and natural science. After defending a widening of the concept of counterfactual thought, and its intrinsic relation with semantic imagination, the role of semantic imagination is briefly discussed in some types of counterfactual thought found in our conceptions of modal concepts, in thought experiments, in apagogical arguments, and in the creative discursive devices.

This volume takes cue from the idea that the thought of no philosopher can be understood without considering it as the result of a constant, lively dialogue with other thinkers, both in its internal evolution as well as in its reception, re-use, and assumption as a starting point in addressing past and present philosophical problems. In doing so, it focuses on a feature that is crucially emerging in the historiography of early modern philosophy and science, namely the complexity in the (...) production of knowledge. The book explores the applicability of this approach to a long-considered armchair philosopher, namely René Descartes, who is now more and more understood as a full-blown scientist, networker, and intellectual éminence grise rather than as the mere philosopher of the cogito, as well as the originator of different ‘Cartesianisms’ which encompassed many ideas and approaches for long captured by dichotomic historiographical categories as rationalism and empiricism, or speculative and experimental philosophy. The essays gathered in the volume aim to address the ways in which Descartes’s philosophy evolved and was progressively understood by scientists, philosophers, and intellectuals from different contexts and eras, either by considering direct interlocutors of Descartes such as Isaac Beeckman and Elisabeth of Bohemia, early modern thinkers who developed upon his ideas and on particular topics as Nicolas Malebranche or Thomas Willis, those who adapted his overall methodology in developing new systems of knowledge as Johannes Clauberg and Pierre-Sylvain Régis, and contemporary thinkers from continental and analytic traditions like Emanuele Severino and Peter Strawson.

This paper takes a fresh look at Johannes Clauberg’s Logica vetus et nova, in order to try to clarify its nature and character. Differently from prior readings of Clauberg that analyze his philosophy from the point of view of the construction of ‘ontology’, the approach of the present paper sees in Clauberg’s philosophy a late-Humanist work, accentuating his pedagogic and hermeneutical interests. Indeed, in Clauberg’s philosophy, hermeneutics and pedagogy are intrinsically bound together. This, the paper suggests, is supported not only (...) by the concrete subject-matters of his logic, but also by the examination of Clauberg’s milieu and of his sources. Analysis, in this framework, has a strictly hermeneutical usage. (shrink)

¿Cómo debe entenderse que una de las innovaciones de mayor alcance epocal del pensamiento cartesiano, a saber, su duda metódica, no haya sido adoptada por la inmediata posteridad filosófica de Descartes? Este artículo investiga las razones de esta supuesta desaparición de la duda en las filosofías de Spinoza y Leibniz mediante una revisión del rol de la duda en las Meditaciones de Descartes. Partiendo de una caracterización del proyecto cartesiano como la búsqueda del fundamento, el artículo muestra que la interpretación (...) de Descartes de la realidad inmediata en términos de representación constituye en realidad la apoteosis de una concepción más antigua que percibe la totalidad de lo ente como contingente y vana. De este modo, la duda no es la suspensión libre del juicio, sino el inevitable estado de irresolución que se deriva de la falta de solidez ontológica que muestra la realidad inmediata entendida como imagen o representación. Se muestra entonces que el pensamiento postcartesiano propiamente no elimina la duda, sino que la incorpora como un supuesto básico, lo cual explica por qué no hay un lugar definido para la misma en el discurso. El desarrollo ulterior del pensamiento moderno puede ser explicado de modo decisivo por medio de esta asimilación implícita de la duda y sus consecuencias. (shrink)

Descartes’ Rules for the direction of the mind presents us with a theory of knowledge in which imagination, considered as an “aid” for the intellect, plays a key role. This function of schematization, which strongly resembles key features of Proclus’ philosophy of mathematics, is in full accordance with Descartes’ mathematical practice in later works such as La Géométrie from 1637. Although due to its reliance on a form of geometric intuition, it may sound obsolete, I would like to show that (...) this has strong echoes in contemporary philosophy of mathematics, in particular in the trend of the so called “philosophy of mathematical practice”. Indeed Ken Manders’ study on the Euclidean practice, along with Reviel Netz’s historical studies on ancient Greek Geometry, indicate that mathematical imagination can play a central role in mathematical knowledge as bearing specific forms of inference. Moreover, this role can be formalized into sound logical systems. One question of general epistemology is thus to understand this mysterious role of the imagination in reasoning and to assess its relevance for other mathematical practices. Drawing from Edwin Hutchins’ study of “material anchors” in human reasoning, I would like to show that Descartes’ epistemology of mathematics may prove to be a helpful resource in the analysis of mathematical knowledge.

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.

Computation and formalization are not modalities of pure abstractive operations. The essay tries to revise the assumption of the constitutive nonsensuality of the formal. The argument is that formalization is a kind of linear spatialization, which has significant visual dimensions. Thus, a connection can be discovered between visualization by figurative graphism and formalization by symbolic calculations: Both use spatial relations not only to represent but also to operate on epistemic, nonspatial, nonvisual entities. Descartes was one of the pioneers of using (...) this kind of two-dimensional spatiality as a cognitive instrument. (shrink)

Although the name of René Descartes (1596-1650) is familiar to anyone with the slightest affinity of philosophy and his ideas have become a commonplace to philosophers, it is not generally known, even amongst histiorians of philosophy, that his fame is actually the result of his revival in the nineteenth century. This thesis explains the historical and systematical reasons for the reinstatement of Descartes in France and Germany. It encounters psychological, religious and epistemological motives for the reinstatement of the ‘father of (...) modern philosophy’ paying special attention to the core elements of Cartesian metaphysics: the cogito, the proofs for the existence of God, and the theory of innate ideas.
