Computational theories of vision typically rely on the analysis of two aspects of human visual function: (1) object and shape recognition (2) co-calibration of sensory measurements. Both these approaches are usually based on an inverse-optics model, where visual perception is viewed as a process of inference from a 2D retinal projection to a 3D percept within a Euclidean space schema. This paradigm has had great success in certain areas of vision science, but has been relatively less successful in understanding perceptual (...) representation, namely, the nature of the perceptual encoding. One of the drawbacks of inverse-optics approaches has been the difficulty in defining the constraints needed to make the inference computationally tractable (e.g. regularity assumptions, Bayesian priors, etc.). These constraints, thought to be learned assumptions about the nature of the physical and optical structures of the external world, have to be incorporated into any workable computational model in the inverse-optics paradigm. But inference models that employ an inverse optics plus structural assumptions approach inevitably result in a na. (shrink)

There are many difficulties with the existing interpretation of Brentano’s works. The problem stems from the fact that Brentano’s works, letters, manuscripts, memoir’s, etc. remain unpublished or undiscovered. Moreover some Brentano’s scholars, namely Kastil and Mayer-Hillebrandt, were incorrect in their method in publishing the philosopher’s works. Namely, they misinterpreted his earlier works by incorporating numerous interpolations from different time periods as being the philosopher’s final thoughts. More importantly, as evidenced by Antonio Russo’s recent discovery, they also failed to realise the (...) fact that Brentano’s own theoretical views or works were mostly based on Aristotle and Thomas thoughts on metaphysics, that Brentano’s main intention was to develop a scientific demonstration on this topic, and that this issue occupied his mind until his death. It is hoped that this paper goes some way in resolving the said errors and coupled with the continue discovery of new material that the jigsaw of Brentano’s works and thinking shall someday be correctly completed.

Brentano clearly asserts, in his Vienna lectures of 1887–1888, that his descriptive psychology is an a priori or “exact” science. Since he rejects Kant's idea of a synthetic a priori, this means that the descriptive psychologist's laws are analytic. My aim in this paper is to clarify and discuss this view. I examine Brentano's epistemology in the Psychology from an Empirical Standpoint and then its later developments. I conclude with a difficulty inherent in Brentano's psychological approach to a priori knowledge.

In recent decades, scholars have shown a distinct new willingness to concede the important place of religion in the life and thought of the philosopher Franz Brentano. However, these studies are still dominated by the presumption that Brentano's life and thought are best understood according to a model of secularisation as a progressive waning of religion. This essay asks whether such a presumption is the best way of understanding the complex interconnections between various elements of his philosophical and religious ideas. (...) It posits that a better appreciation of his position entails a confrontation with Brentano's historical imagination, and especially the structuring role of his approach to the history of philosophy as one manifesting regular cycles of decline and regeneration. Brentano's theory of the four phases of philosophy, though not the final word on how he viewed history, was nevertheless an exercise in thinking about the ways history accommodates various forms of progress and repetition. It was therefore a salutary means for thinking about the evolution of religion in ways that challenge any simple understanding of secularisation. (shrink)

The thesis is defended that the theories of causation, time and space, and levels of reality are mutually interrelated in such a way that the difficulties internal to theories of causation and to theories of space and time can be understood better, and perhaps dealt with, in the categorial context furnished by the theory of the levels of reality. The structural condition for this development to be possible is that the first two theories be opportunely generalized.

Intentionality (‘directedness’, ‘aboutness’) is both a central topic in contemporary philosophy of mind, phenomenology and the cognitive sciences, and one of the themes with which both analytic and Continental philosophers have separately engaged starting from Brentano and Edmund Husserl’s ground-breaking Logical Investigations (1901) through Roderick M. Chisholm, Daniel C. Dennett’s The Intentional Stance, John Searle’s Intentionality, to the recent work of Tim Crane, Robert Brandom, Shaun Gallagher and Dan Zahavi, among many others. In this paper, I shall review recent discussions (...) of intentionality, including some recent explorations of the history of the concept (paying particular attention to Anselm), and suggest some ways the phenomenological approach of Husserl and Heidegger can still offer insights for contemporary philosophy of mind and consciousness.

Both through his own work and that of his students, Franz Clemens Brentano had an often underappreciated influence on the course of 20 th - and 21 st -century philosophy. _The Routledge Handbook of Franz Brentano and the Brentano School_ offers full coverage of Brentano’s philosophy and his influence. It contains 38 brand-new essays from an international team of experts that offer a comprehensive view of Brentano’s central research areas—philosophy of mind, metaphysics, and value theory—as well as of the principal (...) figures shaped by Brentano’s school of thought. A General Introduction serves as an overview of Brentano and the contents of the volume and three separate bibliographies point students and researchers on to further avenues of inquiry. Systematic and detailed, _The Routledge Handbook of Franz Brentano and the Brentano School_ provides readers with a valuable reference to Brentano’s work, and to his lasting importance in the history of philosophy and in contemporary debates.
