Abstract

This book gives a systematic account of Martin Heidegger’s methodology. Contrary to the widespread conception that Heidegger’s (late) philosophy is lacking any kind of verifiable, provable insights, the author shows that a rejection of the scientific method does not imply a rejection of methodological, rigorous thinking. In fact, it can be shown that the method of Heidegger’s philosophy is more rigorous, more strict and more radical than the scientific method. But because the scientific method is conceived of as the non-plus-ultra even within philosophy, in order to outline Heidegger’s methodology we have to give an account of his criticism of the scientific method. By showing the limitations of modern science, we can unfold the possibilities of philosophy.

The book consists of four parts: The first part is about Heidegger’s concept of subjectivity and his criticism of the Cartesian subject-object-dichotomy. The main argument of the first part is that the ‘subject’, inasmuch as it is understood ontologically, is essential for philosophy. We outline this – following Steven G. Crowell – as the philosophical significance of the first-person-perspective (Heidegger’s early philosophy between 1919 and 1927).

The second part is about what we call an ontological theory of constitution: A radicalization of the Kantian transcendental philosophy which does not orbit around transcendental subjectivity, but rather around concrete subjectivity (Dasein vs. the transcendental ego). We take a closer look on what Heidegger has written between 1927 and 1930.

The third part is about Heidegger’s late philosophy. The main topic of this third part is Heidegger’s “seynsgeschichtliche Besinnung auf das machenschaftliche Wesen der neuzeitlichen Wissenschaft“ – which is in essence a closer look on what modern science is, on its relation to technology, and on its very own historicality. We discuss the most famous published texts and lectures between 1930 and 1976, but focus on Heidegger’s Nietzsche lectures and his second magnus opus: the Contributions to Philosophy.

This criticism of modern science is the stepping stone for the fourth and final part, in which we take all the pieces and put them together by giving a systematic account of Heidegger’s methodology. In this final part we take a step back from Heidegger’s texts (and from his language) and confront Heidegger with the most famous criticism by Carl Friedrich Gethmann and Jürgen Habermas.

This allows us to give an account of the central concepts of Heidegger’s methodology: truth, knowledge and validity. We also talk about the status of philosophical concepts and in general: philosophical language, about Heidegger’s theory of philosophical conceptualization, which is known as the method of formal indication and about the possibility of an ontological foundation of modern science and epistemology.
