The article addresses the works of three 19th-century philosophers: Herbart, Bolzano and Lotze. Despite their differences, i will analyze two essential features they share: their refusal to psychologism as the radicalization of psychology as the ultimate source of philosophy , and the positing of an ideal ‘reality’, independent from both sensibility and the mental and linguistic dimensions, upon which the refusal to psychologism is founded . As a conclusion, i will show how, according to these authors, this platonic, ideal background (...) constitutes the very foundation of every meaningful thought. (shrink)

According to Jacques Derrida, the tradition of metaphysics is dominated by a basic distinction between presence and absence that plays a fundamental role in Husserl’s theory of meaning and contaminates the core of his phenomenological project. If Husserl’s distinction between indication and expression in the 1st Logical Investigation is credited for opening a ‘phenomenological breakthrough’, his account of the entwinement between the indicative and expressive functions of linguistic signs is accused of restoring and maintaining the metaphysical primacy of presence. In (...) the last chapters of Voice and Phenomenon, Derrida focuses especially on the cases of indexical or ‘essentially occasional’ expressions, whose concrete meaning is a function of the occasion of their use and which rely on the indicative function of meaning. According to Derrida’s reading, Husserl holds that such indexical meanings like ‘I’, ‘here’ or ‘now’, are necessarily always fulfilled and cannot lack of intuitive fulfilment. Consequently Derrida takes Husserl’s account of the meaning of ‘I’ as an obvious symptom of his inability to move away from the myth of pure expressivity, bringing phenomenology back into the history of metaphysics. Husserl would have failed to acknowledge that indexical meanings, like ideal or objective meanings, can remain unfulfilled and deprived of intuition. This article demonstrates that Derrida’s critique misses the most important point in Husserl’s analysis of the meaning of ‘I’, and argues that indexical or subjective expressions are somehow insensitive to the prospect of intuitive presencing and fulfilment.

In this talk I present the main results from Anta (2021), namely, that the theoretical division between Boltzmannian and Gibbsian statistical mechanics should be understood as a separation in the epistemic capabilities of this physical discipline. In particular, while from the Boltzmannian framework one can generate powerful explanations of thermal processes by appealing to their microdynamics, from the Gibbsian framework one can predict observable values in a computationally effective way. Finally, I argue that this statistical mechanical schism contradicts the Hempelian (...) (1958) thesis that the predictive power of a scientific theory is directly proportional to its explanatory potential, and vice versa. (shrink)

El artículo aborda ciertos pasajes fundamentales de la Wissenschaftslehre de Bolzano, analizando algunos de sus conceptos claves tales como los de «proposición en sí» o «representación en sí». Haciendo especial hincapié en el estatus ontológico peculiar de estas «entidades en sí» que presenta Bolzano, mostraremos que su obra desarrolla una auténtica teoría semántica de la dimensión del sentido y de lo pensable, que no sólo no depende de la ontología, sino que desborda a la misma.
