Libet considers “positive free voluntary acts” as mere illusions, admitting free will only as Veto. This essay shows seven ways by which we can gain evident knowledge about positive and negative free will, through: (1) the immediate evidence of free will in the cogito, (2) the light of the necessary essence of free will, (3) the experience of moral “oughts” in whose experience freedom is co-given, (4) any denial of human free will entails its assertion or recognition, (5) the objects and subjects of certain acts disclose free will, (6) in a world without free agents there would be no explanation of the beginning of efficient causality, and (7) Veto-power of the will logically presupposes positive free will. Libet’s experiments confirm that the free decision to act at a certain time and the preceding and accompanying free acts make new energy to burst forth in the brain.

The question ‘What is death?’ is by no means exclusively or primarily a question of medical science. It is, in the last analysis, a philosophical question. The philosopher’s role in the discussion of death is twofold: On the one hand, he has to explore those highly intelligible and essentially necessary aspects of death which no other human science investigates. This task includes a phenomenology of life and death, an ontology and metaphysics, as well as a philosophical anthropology of death. It likewise includes an analysis of the language of death and life and of the logical structure of the arguments used in the debates about life and death. On the other hand the philosopher has to warn representatives of other disciplines against concluding too much from the little they know and extending their methods to areas where they are not appropriate. Careful reflection on both philosophical knowledge and philosophical ignorance concerning death shows, I shall argue, that the definition of death in terms of ‘brain death’ ought to be rejected.

In an enlightening dialogue with Descartes, Kant, Husserl and Gadamer, Professor Seifert argues that the original inspiration of phenomenology was nothing other than the primordial insight of philosophy itself, the foundation of philosophia perennis . His radical rethinking of the phenomenological method results in a universal, objectivist philosophy in direct continuity with Plato, Aristotle and Augustine. In order to validate the classical claim to know autonomous being, the author defends Husserl's methodological principle "Back to things themselves" from empiricist and idealist critics, including the later Husserl, and replies to the arguments of Kant which attempt to discredit the knowability of things in themselves. Originally published in 1982, this book culminates in a phenomenological and critical unfolding of the Augustinian cogito , as giving access to immutable truth about necessary essences and the real existence of personal being

Following an ardent debate in the 1930s on the question over whether something like a "Christian philosophy" exists, as Etienne Gilson, Jacques Maritain, and others held, the term was used by many thinkers and rejected by many others, not only by Heidegger who called it a contradiction in terms, an "iron wood," but also by Thomists who wanted to see philosophy and Christian faith strictly separated. Seifert analyses five understandings of the term "Christian philosophy" which have never been expounded with such clarity and which he rejects for different, partly for opposite, reasons. He presents these senses of Christian philosophy, and his reasons for rejecting them, in clear, straight-forward language. He presents for the first time a series of eleven wholly different and thoroughly positive and fruitful ways of understanding the term "Christian philosophy." Identifying and distinguishing these legitimate ways to speak of "Christian philosophy" shed light on the manifold fruitful relations between reason and faith. In a second part of the book, Seifert gives an example of Christian philosophy in the sense of a philosophy of religion that shows the absolute presupposedness and necessity of the existence of human, divine, and angelic free will to make any sense of divine revelation and of Christian religion. In a third part, he presents a penetrating analysis of seven indubitable evidences that demonstrate the nature and real existence of human free will. The book is introduced by the eminent Thomist philosopher, John Finnis.

Este estudo tem por objeto a filosofia scotista dos transcendentais, em especial a filosofia dos transcendentais como “perfeições puras”. Isso levará a uma consideração particular da “liberdade” como uma perfeição pura, bem como à concepção de um novo conceito de amor, não presente no eudemonismo aristotélicotomístico. PALAVRAS-CHAVE – Duns Scotus. Filosofia dos transcendentais. Perfeições puras. Liberdade. Amor. Crítica ao eudemonismo. ABSTRACT The object of this study is Scotus’s philosophy of the transcendentals, particularly the philosophy of the transcendentals as “pure perfections”. That will bring into a special consideration of “freedom” as a pure perfection, as well as into the formulation of a new concept of love, not to be found in the Aristotelian-Thomistic eudaimonism. KEY WORDS – Duns Scotus. Philosophy of the transcendentals. Pure perfections. Freedom. Love. Critique on eudaimonism
