Epistemology today centrally concerns the conceptual analysis of knowledge. Historically, however, this is a concept that philosophers have seldom been interested in analysing, particularly when it is construed as broadly as the English language would have it. Instead, the overriding focus of epistemologists over the centuries has been, first, to describe the epistemic ideal that human beings might hope to achieve, and then go on to chart the various ways in which we ordinarily fall off from that ideal. I discuss (...) in detail two historical manifestations of idealized epistemology — Aristotle and Descartes — and then consider how this perspective might make a difference to the discipline today. In the end, an idealized epistemology points toward a normative, prescriptive rather than descriptive enterprise. (shrink)

Hay tres asuntos principales que están bajo discusión pública dentro del Aristotelismo de los siglos XV y XVI. El primero es de carácter metodológico y se refiere al rol de la evidencia científica. El segundo se trata de la inmortalidad del alma. Ambos son bastamente estudiados en los siglos XX y XXI. La tercera cuestión se relaciona con las características y el rol del primer motor, que es Dios mismo. Este argumento, que involucra a casi todos los académicos más importantes (...) del humanismo renacentista, es poco profundo en comparación con los otros, incluso cuando juega un papel importante tanto desde el punto de vista filosófico, como desde el teológico. Puede ser útil examinar cómo algunos pensadores de los siglos XV y XVI, tales como Elia del Medigo, Tommaso De Vio y Marco Antonio Zimara, han tratado de reconciliar la causalidad del primer motor aristotélico, que no aporta a la creación, con el concepto bíblico de Dios. En particular, la discusión se enfoca en la manera en que el primer motor, que provee el único movimiento diario de los cielos, también pueda en alguna manera ser productor del ser. (shrink)

The Renaissance sceptic and medical doctor Francisco Sanchez has been rather unduly neglected in scholarly work on Renaissance scepticism. In this paper I discuss his scepticism against the background of the ancient distinction between Academic and Pyrrhonian scepticism. I argue that Sanchez was a Pyrrhonist rather than, as has been claimed in recent years, a mitigated Academic sceptic. In keeping with this I shall also try to show that Sanchez was crucially influenced by the ancient medical school of empiricism, a (...) school closely allied with Pyrrhonism. (shrink)

As Roger Ariew shows, one of the most fascinating challenges for the authors trying to create a Cartesian complete course on philosophy was coming up with a Cartesian Logic based on the existing texts of the master. Were the few simple rules from the Discourse on Method the "logic" of Descartes? Were the Rules for the Direction of the Mind "logic"? How can we even have a logic without syllogism? When looking at the authors studied by Ariew one finds that (...) the best that they could come up was adding some Cartesian elements on what remains basically a traditional Aristotelian Logic. It seems that there was no Cartesian Logic after all.I want to show here that Cartesian Logic is something else, not exactly... (shrink)

This paper defends a version of J. H. Randall’s thesis that modern empiricism is rooted in the Scholastic regressus method epitomized by Jacopo Zabarella in De Regressu (1578). Randall’s critics note that the empirical practice of Galileo and his contemporaries does not follow Zabarella. However, Zabarella’s account of the regressus is imprecise, which permitted an interpretation introducing empirical hypothesis testing into the framework. The discourse surrounding Galileo’s lunar observations in Sidereus Nuncius (1610) suggests that both Galileo and his interlocutors amended (...) the regressus method in this way, such that a developmental narrative links Scholastic logic to Galilean science.

The main thrust of the argument of this thesis is to show the possibility of articulating a method of construction or of synthesis--as against the most common method of analysis or division--which has always been (so we shall argue) a necessary component of scientific theorization. This method will be shown to be based on a fundamental synthetic logical relation of thought, that we shall call inversion--to be understood as a species of logical opposition, and as one of the basic monadic (...) logical operators. Thus the major objective of this thesis is to This thesis can be viewed as a response to Larry Laudan's challenge, which is based on the claim that ``the case has yet to be made that the rules governing the techniques whereby theories are invented (if any such rules there be) are the sorts of things that philosophers should claim any interest in or competence at.'' The challenge itself would be to show that the logic of discovery (if at all formulatable) performs the epistemological role of the justification of scientific theories. We propose to meet this challenge head on: a) by suggesting precisely how such a logic would be formulated; b) by demonstrating its epistemological relevance (in the context of justification) and c) by showing that a) and b) can be carried out without sacrificing the fallibilist view of scientific knowledge. OBJECTIVES: We have set three successive objectives: one general, one specific, and one sub-specific, each one related to the other in that very order. (A) The general objective is to indicate the clear possibility of renovating the traditional analytico-synthetic epistemology. By realizing this objective, we attempt to widen the scope of scientific reason or rationality, which for some time now has perniciously been dominated by pure analytic reason alone. In order to achieve this end we need to show specifically that there exists the possibility of articulating a synthetic (constructive) logic/reason, which has been considered by most mainstream thinkers either as not articulatable, or simply non-existent. (B) The second (specific) task is to respond to the challenge of Larry Laudan by demonstrating the possibility of an epistemologically significant generativism. In this context we will argue that this generativism, which is our suggested alternative, and the simplified structuralist and semantic view of scientific theories, mutually reinforce each other to form a single coherent foundation for the renovated analytico-synthetic methodological framework. (C) The third (sub-specific) objective, accordingly, is to show the possibility of articulating a synthetic logic that could guide us in understanding the process of theorization. This is realized by proposing the foundations for developing a logic of inversion, which represents the pattern of synthetic reason in the process of constructing scientific definitions. (shrink)
