Abstract: Being-in-the-world defines in Heidegger an ontological and practical existential situation that in a first approach characterizes intellectual knowledge, an approach related to the Husserlian notion of intentionality. In his Curso de teoría del conocimiento, Polo rectifies this characterization, stressing the primacy of theory regarding action, and interpreting the practical (technical) relationship with the world as a lower level of “having”. Making some comparisons between Husserl, Scheler and Jonas, in connection with Polo’s thought, the article presents different accounts of the notion of the world (phenomenological, metaphysical, moral) that allow to clarify the problem of the relationship between contemplation and action in the world.

In this study first we delineate an overview of the main philosophical positions on the problem of the distinction between mental acts and physical acts in man. There follows an exposition of the topic, inspired by Aristotle’s and Aquinas’s principles. Sensitive operations are physical, but in the sense of an ‘elevated body,’ thanks to a higher formal dimension, which informs the organic basis. Intellectual operations, by contrast, are completely immaterial, though they act united to the sensitive cerebral basis. Accordingly, they have neurological correlations, guided by the intentional causality of the intellect. The intellectual act and its neural basis form a unique act, which is integrated by several cognitive dimensions. Our intelligence uses the brain as an intrinsic instrument, but we also need external ‘cognitive’instruments, namely written texts and computers. The intellectual development of people can be explained by the interaction of these different dimensions.

This paper aims to explain how the human Self can be said a cause of his/her free actions, especially when they are voluntary and physical. First it is analyzed the natural causation in the physical world, particularly in self-organized living beings and afterwards in animal intentional behaviour, which is guided by cognition and emotions. An important distinction between downward causation and bottom-up causation is useful to explain the complex causality in self-organized intentional beings. Downward causation, coming from a higher level, has in influence over lower ontological levels. Bottom-up causation operates inversely. It is also drawn a distinction between the “natural Self” (nature enhanced by habits) and the “intentional Self” (a subject endowed with consciousness and the power of controlling operations). This framework is applied to man, whose higher downward causality comes from the person (intellect and free will) and, guiding the sensitive lower layer of his/her nature, reaches in a quite natural way the voluntary control of the body.

This paper presents current trends in philosophy of mind and philosophy of neuroscience, with a special focus on neuroscientists dealing with some topics usually discussed by philosophers of mind. The aim is to detect the philosophical views of those scientists, such as Eccles, Gazzaniga, Damasio, Changeux, and others, which are not easy to classify according to the standard divisions of dualism, functionalism, emergentism, and others. As the variety of opinions in these fields is sometimes a source of confusion, it is worth the effort to obtain an overall panorama of the topic. A general conclusion on epistemological and ontological issues, concerning the relationship between neurobiology and philosophy and the multi-level account of the embodied mind, is proposed.

The article examines Wittgenstein’s thought on the language of pain in first and third person. Relevant grammatical differences, according to the typical analytical method of this philosopher, are highlighted not only in relation to the two perspectives, but also regarding the use of cognitive verbs such as ‘feeling’ and ‘knowing’. The exam of many texts suggests some issues concerning the relationship between personal experiences, empathic grasping of other’s feelings and their conceptual translation. A brief comparison with some Thomas Aquinas’ texts complements the proposal of the existence of non intentional knowledge.

The article presents the relationship between religious faith and natural sciences within a historical perspective. Three great periods are distinguished: classical, enjoying a substantial harmony between science and belief in God; modern period, characterized by a radical rationalism that can be seen as the root of the structural conflict between science and religion; contemporary phase, with the collapse of rationalism, notwithstanding the great prestige of natural science, often perceived within a secularist framework. It is argued that no objective reasons oppose today scientific knowledge to theology and religion. The present state of natural sciences is favourable for a new complementarity between secular/rational views and theological/religious faith.

Cognitive science, and especially neuroscience, currently addresses the philosophical problem of human free choice. This article proposes addressing the problem with the methodology of a confrontation between a phenomenological analysis of human decisions and some main points of philosophy of mind and of neuroscience. The author offers a proposal for the meaning of a 'free' decision, within the context of intentional actions. While avoiding dualism, which is linked to a pure opposition between a disincarnate act of will and a merely physiological account of what is going on in the brain, the author proposes a unitary conception of intentional cognitive/emotional circuits both in animals and in human beings. Neural activations are just a dimension of those circuits and need to be analyzed at the intentional level. Truth and good as a permanent background in human intentional powers provide the root of free choices, as essentially different from animal choices.
