Michel Henry (1922-2002) was a leading 20th century French philosopher in the school of phenomenology. The final three books of his career focus on explicitly Christian themes and texts, and these books are now known as his “Christian trilogy”. This essay focuses on this trilogy in an exposition of Henry’s Christology, his concept of the Self, and how Christology and selfhood relate to each other. The exposition of Henry’s thought on this issue is stated in the following thesis, broken into three sections: 1) God always reveals himself as Christ 2) who reveals the Truth of the Self, 3) this revelation being identical with salvation. Said again, 1) God’s Revelation is always God’s self-revelation in Christ, and is never separate from 2) the human condition of the Self as a Son of God, and this condition is never separate from 3) salvation. Revelation, selfhood, and salvation. This essay is largely expository but several constructive attempts are made to apply Henry’s philosophy of Christianity to key theological themes, namely atonement, pneumatology, and ecclesiology.

Drawing on the ideas of J.G. Fichte and M. Merleau-Ponty, I argue that experience and freedom are intersubjective, linguistic, and bodily. In the first chapter, I take up Fichte's three "fundamental principles" from the Science of Knowledge alongside his ideas of embodiment and intersubjectivity from the Foundations of Natural Right to show that all experience is an indefinite mixture of self and not-self, and, therefore, that both the experiences of self-consciousness and its freedom must also be accomplished with reference to the not-self, and particularly others. The second chapter is an examination of Merleau-Ponty's account of expression in his Phenomenology of Perception. The key insight I pursue here is that the medium of expression, which makes possible all significance, is bodily and intersubjective, and that any expressive act is therefore both self-opaque and soliciting cooperation. In the end, I turn to how this cooperation, i.e. freedom, should be enacted.

This thesis pays attention to the nature of human being that comes to light in Martin Heidegger's Being and Time. In particular, it attempts to show that his notion of authenticity allows for a distinctive and fruitful conception of ethical responsibility, albeit one that challenges us to rethink ethics and responsibility anew. I claim that if authenticity is ‘owning’ one's existence in a way that is properly fitted to Dasein's ontological way of being (as nonself-identical, ecstatic temporality), this ownership of self will necessarily be the stance of recognizing and responding to that which always already includes a network of relations involving world and others. On such an understanding, genuine existential care for oneself is also care for others in the most originary way possible. Such an ontological picture has been criticized by some commentators as being too formal, insufficiently historical, and lacking genuine mediation – in short, for being ineffectual as a normative force in real-life situations. The main contribution of this thesis is to argue against such an interpretation by showing that Heideggerian authenticity is a properly dialectical concept, capacious enough to account for the legitimate concerns raised by such criticisms, while also being productive for new articulations of what is really normative about human relations.

The term fordoblelse—usually translated as “redoubling” in English—is found relatively infrequently in Kierkegaard’s corpus and has posed something of a puzzle for scholars. In this thesis, I trace Kierkegaard’s use of the term throughout his writings, seeking to determine the common ground between the rather disparate ways in which fordoblelse appears. I explore the relationship between redoubling and such major Kierkegaardian themes as indirect communication, paradox, and the constitution of the self, and I attempt to tease out the similarities and divergences between redoubling and two other Kierkegaardian terms, “repetition” and “reduplication.” Ultimately, I conclude that redoubling functions for Kierkegaard as a structural term that provides him with a vocabulary to describe the many paradoxes at work in Christian faith.
