La contingencia es para Leibniz, junto con la espontaneidad y la inteligencia, un componente esencial de la definición de la verdadera libertad, que nuestro pensador califica como uno de los problemas filosóficos por excelencia: “la cuestión de saber cómo se puede salir del laberinto, la gran cuestión de lo libre y lo necesario”. Leibniz, en diálogo con sus referentes polémicos diferenciará –siguiendo la herencia agustiniana- entre el “libre albedrío” y la “verdadera libertad” o determinación racional, a la que sitúa en (...) un camino intermedio entre el determinismo absoluto y la indiferencia de equilibrio. La libertad de los seres racionales será para Leibniz la condición sine qua non para entrar a formar parte del el reino de la gracia, un mundo moral dentro del mundo natural en el que impera el bien común.

The relation between Kant’s conception of modalities in the Postulates of Empirical Thought and Hegel’s conception in the Logic of Essence has not been addressed in the current scholarship. I argue that there is in fact a close connection that becomes visible if the desideratum which is implied by Kant’s conceptions is understood. Thus, after an analysis of the Kantian modal postulates, the article shows that they are sufficient to characterize the necessity of Kant’s Grundsätze and, hence, a specific form (...) of synthetic propositions a priori. However, I will prove that they are insufficient to characterize Kant’s synthetic propositions a priori about transcendental philosophy. This insufficiency in the characterization of transcendental philosophy itself brings into the arena Hegel, who supplements the Kantian modalities with a self-reflexive form of transcendental modality.

Seventeenth century philosopher Gottfried Leibniz's contributions to metaphysics, mathematics, and logic are well known. Lesser known is his ‘invention’ of deontic logic, and that his invention derives from the alethic logic of the Aristotelian square of opposition. In this paper, I show how Leibniz developed this ‘logic of duties’, which designates actions as ‘possible, necessary, impossible, and omissible’ for a ‘vir bonus’ . I show that for Leibniz, deontic logic can determine whether a given action, e.g. as permitted, is therefore (...) obligatory or prohibited . Secondly, since the deontic modes are derived from what is possible, necessary, etc., for a good person to do, and that ‘right and obligation’ are the ‘moral qualities’ of a good person, we can see how Leibniz derives deontic logic from these moral qualities. Finally, I show how Leibniz grounds a central deontic concept, namely obligation, in the human capacity for freedom. (shrink)

Si Dios es la razón suficiente del mundo, entonces parece seguirse que todos los eventos son consecuencia necesaria de un ser necesario. Para evadir esta conclusión, Leibniz formula en la década de 1670 una concepción modal que funda la contingencia en un rasgo lógico e intrínseco de las ideas de las cosas: la posibilidad de concebir la idea contraria sin contradicción. Hacia 1686, Leibniz complementa esta primera concepción con lo que considera su solución definitiva al problema de la contingencia: la (...) teoría del análisis infinito. Sin embargo, en otros escritos de ese año, propone dos vías alternativas de fundamentación de la contingencia. Este trabajo sugiere que esa pluralidad de modelos explicativos converge en una concepción integral de las modalidades que subyace como trasfondo de la reflexión modal leibniziana. If God is the sufficient reason for this world, then it seems to follow that every event is a necessary consequence of a necessary being. in order to avoid this conclusion, Leibniz states, during the 1670's, a modal conception that grounds contingency on a logical feature which is intrinsic to the ideas of things: the possibility of conceiving the opposite idea without contradiction. Towards 1686, Leibniz complements this first conception with what he considered to be his definitive solution to the problem of contingency: the theory of infinite analysis. However, in other writings from the same year, he proposes two different ways to explain contingency. This paper suggests that this plurality of models converges in a global conception of modalities, which lies at the background of Leibniz's modal thought. (shrink)

En sus últimos años, Leibniz emplea el concepto de necesidad moral para cualificar la elección divina de lo óptimo. Sin embargo, Leibniz no explica este concepto con precisión. El presente trabajo intenta mostrar que la necesidad moral leibniziana no puede entenderse como una modalidad puramente deóntica, porque ello contraría los fundamentos metafísicos que hacen al carácter teleológico de su ética. El artículo propone también una interpretación del contenido alético de tal noción, basada en la conexión necesaria que Leibniz parece atribuir (...) a la relación entre la voluntad y la tendencia al bien. Dicha necesidad afirmaría que, aun cuando toda elección es contingente, en tanto entraña una infinidad de consideraciones, el Dios leibniziano está metafísicamente necesitado a seguir el criterio de lo mejor. In his last years, Leibniz employs the concept of moral necessity to qualify God's choice of the best. However, he doesn't explain this concept accurately. This paper intends to show that leibnizian moral necessity cannot be conceived as a purely deontic modality, because it would be contrary to the metaphysical grounds which make Leibniz's ethics strictly teleological. This paper also proposes an interpretation of the alethic content of this concept, based on the necessary connection that Leibniz seems to assign to the relationship between free will and the tendency towards good. What this necessity entails is that, for Leibniz, even though the infinity of reasons involved makes every choice contingent, God is metaphysically necessitated to follow the rule of the best.
