Böcker av Josef Seifert

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 (rather misleading) 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 (but also of Muslim and Jewish) 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 (in a so-called "libertarian" sense that rejects the thesis of the compatibility between free will and determinism). The book is introduced by the eminent Thomist philosopher, John Finnis.

The term "e;method"e; of realist phenomenology and philosophy can refer to three kinds of things which are being explored extensively in this work: (1) Kinds of philosophical knowledge used to return to things themselves: intellectual "e;vision"e; of necessary intelligible essences, insights into necessary states of affairs, knowledge of less than necessary essences, knowledge of existence as such, of the ego cogitans and of a concretely existing world, other persons, and the absolute being, deductive forms of reasoning, and others. (2) Ways to achieve such knowledge: such as various types of distinctions, asking proper questions, correct use of analogies, and replies to objections. (3) Finally, these methods include several "e;tricks"e; and devices such as methodic doubt and epoche; these are subordinated to the other methods, and neither necessary nor universal tools of all philosophical knowledge.
