Leibniz often refers to the Principle of Sufficient Reason (PSR) as something like a first principle. In some texts, however, he attempts to give positive arguments in its favor. I examine two such arguments, and find them wanting. The first argument has two defects. First, it is question-begging; and second, when the question-begging step is excised, the principle one can in fact derive is highly counter-intuitive. The second argument is valid, but has the defect of only reaching a nearly trivial (...) conclusion. (shrink)

In the last few decades, the historiographical categories rationalism and empiricism have been criticized for their limitations to explain the complex positions and the links held by the philosophers tradiotnally attached to them. This narrative was firstly conceived by Kantian German historians and began to become standard at the turn of the twentieh century. Nonetheless, nineteenth-century French historiography developed other narratives by which early modern philosophers were classified according to alternative criteria. In the first edition of Histoire comparée des systémes (...) de philosophie (1804), Joseph-Marie Degérando distinguishes three first-order early modern schools founded by Bacon, Descartes and Leibniz, respectively. Degérando introduces the empiricism and rationalism distinction as one among others, and not as the fundamental one. In addition, he separates empiricism from experimental philosophy. The last one, along with speculative philosophy, is said to conciliate senses and reason. As a result, this account offers philosophical groupings different from those constructed by the standard narrative. Furthermore, it draws on labels and classification criteria which were part of the early modern philosophical discourse. (shrink)

Maxwell’s Classical Electrodynamics (MCED) suffers several inconsistencies: (1) the Lorentz force law of MCED violates Newton’s Third Law of Motion (N3LM) in case of stationary and divergent or convergent current distributions; (2) the general Jefimenko electric field solution of MCED shows two longitudinal far fields that are not waves; (3) the ratio of the electrodynamic energy-momentum of a charged sphere in uniform motion has an incorrect factor of 4/3. A consistent General Classical Electrodynamics (GCED) is presented that is based on (...) Whittaker’s reciprocal force law that satisfies N3LM. The Whittaker force is expressed as a scalar magnetic field force, added to the Lorentz force. GCED is consistent only if it is assumed that the electric potential velocity in vacuum, ’a’, is much greater than ’c’ (a ≫ c); GCED reduces to MCED, in case we assume a = c. Longitudinal electromagnetic waves and superluminal longitudinal electric potential waves are predicted. This theory has been verified by seemingly unrelated experiments, such as the detection of superluminal Coulomb fields and longitudinal Ampe`re forces, and has a wide range of electrical engineering applications.

The force law of Maxwell’s classical electrodynamics does not agree with Newton’s third law of motion (N3LM), in case of open circuit magnetostatics. Initially, a generalized magnetostatics theory is presented that includes two additional physical fields B_Φ and B_l, defined by scalar functions. The scalar magnetic field B_l mediates a longitudinal Ampère force that balances the transverse Ampère force (aka the magnetic field force), such that the sum of the two forces agrees with N3LM for all stationary current distributions. Secondary (...) field induction laws are derived; a secondary curl free electric field E_l is induced by a time varying scalar magnetic field B_l, which isn’t described by Maxwell’s electrodynamics. The Helmholtz’ decomposition is applied to exclude E_l from the total electric field E, resulting into a more simple Maxwell theory. Decoupled inhomogeneous potential equations and its solutions follow directly from this theory, without having to apply a gauge condition. Field expressions are derived from the potential functions that are simpler and far field consistent with respect to the Jefimenko fields. However, our simple version of Maxwell’s theory does not satisfy N3LM. Therefore we combine the generalized magnetostatics with the simple version of Maxwell’s electrodynamics, via the generalization of Maxwell’s speculative displacement current. The resulting electrodynamics describes three types of vacuum waves: the Φ wave, the longitudinal electromagnetic (LEM) wave and the transverse electromagnetic (TEM) wave, with phase velocities respectively a, b and c. Power- and force theorems are derived, and the force law agrees with Newton’s third law only if the phase velocities satisfy the following condition: a >> b and b = c. The retarded potential functions can be found without gauge conditions, and four retarded field expressions are derived that have three near field terms and six far field terms. All six far field terms are explained as the mutual induction of two free fields. Our theory supports Rutherford’s solution of the 4/3 problem of electromagnetic mass, which requires an extra longitudinal electromagnetic momentum. Our generalized classical electrodynamics might spawn new physics experiments and electrical engineering, such as new photoelectric effects based on Φ- or LEM radiation, and the conversion of natural Φ- or LEM radiation into useful electricity, in the footsteps of dr. N. Tesla and dr. T.H. Moray. (shrink)

El canon literario implica un proceso de selección sistemático y jerárquico de escritores, obras y géneros con el fin de delimitar un corpus modélico imitableligado fuertemente a la instrucción pedagógica. En el presente trabajo se analizará el particular proceso de formación y conformación del canon –así como surecepción y transformación respecto de los cánones previos– establecido por Quintiliano en el Libro 10 de la Institutio Oratoria, a fin de demostrar que los criterios de selección que guían dicho canon exceden la (...) mera función didáctica.

This paper draws attention to the Symposium's concern with epideictic rhetoric. It argues that in the Symposium, as in the Gorgias and the Phaedrus, a contrast is drawn between true and false rhetoric. The paper also discusses the dialogue's relationship to drama. Whereas both epideictic rhetoric and drama were directed to a mass audience, the speeches in the Symposium are delivered to a small, select group. The discussion focuses on the style of the speeches delivered by Aristophanes, Agathon, Socrates and (...) Alcibiades. Aristophanes speaks in the simple style of comedy, fable and folktale, also used by Protagoras in Plato's Protagoras. Agathon speaks in the high-flown style of Gorgias. Socrates' speech is a miniature Platonic dialogue, and both Alcibiades' speech and Socrates' speech may be compared to satyr play. The paper concludes with a suggestion that the claim at 223D, that the same person should be able to write both comedy and tragedy, refers to style as well as subject-matter. (shrink)

This article revisits the issue of female choruses in Classical Athens and aims to provide an alternative to the common pessimistic view that emphasizes the restriction of female choreia by the gender ideology of the democracy. We agree that Athens did not have the kind of female choral culture that is documented for Sparta or Argos, but a review of the evidence suggests that women did dance regularly both in the city itself and elsewhere in Attica, although not at the (...) ideologically most marked occasions such as the City Dionysia. The latter part of the article turns from actual choruses to their representation in textual and iconographic sources. An important reason why modern scholarship sometimes underestimates the extent of female choreia in Athens, we suggest, is that Athenian sources are often purposefully elusive in their representation of female choruses.

One of the main characteristics of the philosophy of Descartes which marked the starting point of modern philosophy and was continued by English empiricism and German Idealism is a special attention to the subject instead of cosmos, being or God. But what caused such a turn to subject? With a historical linguistic approach it can be shown that the replacement of old languages of philosophy namely Greek, Arabic and Latin language by modern European languages namely French, English and German can (...) be one of the causes of that turn in the history of philosophy. It seems interesting that the change in modern European language occurred exactly at the same time the modern philosophy appeared. In this research we will concentrate on the word order and the possibility of the omission of the subject in the sentence. In modern European languages there is a insistence on the subject to appear at the beginning of the sentence. This can lead to a special attention to the subject in philosophical aspect. It may seem interesting that old languages of philosophy are null-subject languages in the sense that in these languages the subject can be omitted. In these languages the subject sometimes comes after the verb or even will not appear in the phrase. That may seem why in those languages a philosophy similar to modern philosophy did not appear. Finally it will be shown that the change in language did not confine to mere language and has important philosophical implications. (shrink)

En este artículo, presentamos primero un análisis de la proposición “Dios elige siempre lo mejor”, con el fin de indagar qué tipo de necesidad cabe atribuírsele. Puesto que Leibniz rechaza la necesidad geométrica en el ámbito de la libre elección divina, examinamos luego qué clase de relación hay entre el entendimiento y el bien, es decir, si corresponde prioritariamente a la razón juzgar sobre el bien o lo mejor. Del mismo modo, analizamos a continuación el vínculo que liga a la (...) voluntad con el bien, por cuanto este último parece ser, al mismo tiempo, el objeto natural de la voluntad. En ambos casos, el análisis se aplica tanto a Dios como a las criaturas racionales. Una aparente inconsistencia parece suscitarse entre un entendimiento y una voluntad que “se disputan” el mismo objeto. Nuestro objetivo es mostrar que, aunque la prioridad de examinar sobre el bien pueda recaer en una u otra facultad, según el contexto escritural, la cuestión carece de sentido al aplicársela a Dios. En suma, la ambivalencia se diluye cuando advertimos que ello resulta de una ficción humana, a saber que hay un hiato entre deber y querer. (shrink)

among nicolas malebranche’s most influential contributions to philosophy are his defense of occasionalism, his highly original theodicy, and his philosophical method elaborated in greatest detail in his magnum opus De la Recherche de la vérité. In his account of occasionalism, Malebranche argues that finite things have no causal power and that God is the only true causal agent. Malebranche’s theodicy—his attempt to reconcile the existence of evil in the world with the existence of an all-good and all-powerful God—is most thoroughly (...) developed in Traité de la nature et de la grâce. Malebranche’s theodicy revolves around a.. (shrink)
