This thesis deals with the relation of Hellenic philosophy to evolutionary biology. The first part entails an explication of Hellenic cosmology and metaphysics in its traditional understanding, as the Western component of classical Indo-European philosophy. It includes an overview of the relevant contributions by the Presocratics, Plato, Aristotle, and the Neoplatonists, focusing on the structure and origin of both the intelligible and sensible worlds. Salient aspects thereof are the movement from the transcendent Principle into the realm of Manifestation by means of the interaction between Essence and Substance; the role of the Logos, being the equivalent of Plato’s Demiurge and Aristotle’s Prime Mover, in the cosmogonic process; the interaction between Intellect and Necessity in the formation of the cosmos; the various kinds of causality contributing to the establishment of physical reality; and the priority of being over becoming, which in the case of living organisms entails the primacy of soul over body. The first part of the thesis concludes with a discussion of the implications of Hellenic cosmology and metaphysics for evolutionary biology, including an affirmation of final and formal causality over and against its rejection by the modern scientific project. The second part commences with a delineation of organic form and transformation, emphasizing the mathematical foundations thereof. It continues with a critical consideration of the modern evolutionary theory on both scientific and philosophical grounds. In the process a fundamental distinction is made between micro- and macro-evolution, involving the reshuffling of existing genetic material which is acted upon by natural selection, and the production of new genetic material by means of macro-mutations, respectively. In the remainder of the thesis the macro-evolutionary process is described as mainly lawful, directed and convergent, instead of contingent, undirected and divergent as postulated in the modern evolutionary synthesis. This approach does not preclude the recognition of exceptions, due to the limitation of Intellect by Necessity – that is to say, of teleology by mechanism. / Religious Studies & Arabic / D.Litt. et Phil.

Cette étude se propose de rendre compte du conflit qui opposa Plotin aux Gnostiques. Uneintroduction met en scène les protagonistes et décrit les circonstances de leur l’affrontement.Une première partie étudie la forme de cette polémique exceptionnelle dans les traités dePlotin, la rapproche de celle des hérésiologues chrétiens à l’encontre de ces mêmesGnostiques et fait l’hypothèse qu’elle ne fut pas ignorée de Plotin. Les parties suivantesprésentent la philosophie de Plotin pour l’opposer à la doctrine gnostique dans les domainescosmologique, théologique et anthropologique. Elles présentent et étudient, en chacun de cesdomaines, les critiques de fond que Plotin adresse aux thèses de l’adversaire, lui reprochant deméconnaître la nature des réalités dont il traite, de tenir des discours dépourvus de logique, dene proposer aucune méthode pour réaliser ses objectifs (le salut). Les critiques de Plotin àl’encontre des Gnostiques constituent une défense du platonisme et de la philosophie elle-même,ainsi que de toutes les valeurs sur lesquelles se fonde toute la pensée de Plotin. / This study accounts for the conflict between Plotinus and the Gnostics. The introductionportrays the protagonists, and describes the circumstances of their confrontation. The first partstudies the form of this exceptional controversy in the treaties of Plotinus, draws a parallelwith the controversy between the Christian Heresiologists and the Gnostics, and hypothesizesthat the later was not unknown to Plotinus. The subsequent parts explain the philosophy ofPlotinus and contrast it with the Gnostic doctrine in the cosmological, theological andanthropological domains. They present and analyse, in each of these areas, the fundamentalcritiques that Plotinus addresses to his opponents, accusing them of misunderstanding thenature of the realities that they deal with, of making speeches devoid of logic, and ofproposing no method to achieve their aims (salvation). The critiques of Plotinus against theGnostics constitute a defense of Platonism and of philosophy itself, and also of all the valuesthat underlie the thought of Plotinus.

Clementine scholarship acknowledges Clement's doctrine of the Incarnation and generally maintains that for Clement the divine Logos assumed human flesh. However, because of Clement's complex logology and three passages suggesting a docetic interpretation of Christ's flesh, scholars tend to move away from addressing the Incarnation and treat either the metaphysics of the multiple logoi theory or the question of Clement's Docetism, or both. Because of this diversion in research, there remains a gap in the literature around Clement's teachings about the Incarnation. This thesis begins to fill the gap by explaining Clement's view of the Incarnation, which he connects to the emergent ‘exchange' doctrine, envisaged as a divine mission. It situates Clement as an heir of the apostolic tradition while he engages with Greek philosophy and Gnostic belief. The research delineates Clement's gnostic tradition, which he considered faithful to the Old Testament and to the teachings of the apostles. The investigation collates Clement's usage of John 1:14 and the term ginomai linked with Logos, anthropos, and sarx. It examines Clement's discussion in Stromateis VII.2, where he claims the Logos assumed flesh susceptible to suffering, emotions, and physical sensibilities. In Clement's teachings, the Logos became both anthropos and sarx so that anthropos might become theos. This thesis outlines Clement's usage of the terms parousia and epiphaneia (appearing), showing they are consequential to the Incarnation. Clement presents the Logos as Saviour, who conquers malevolent powers and death to release humankind from corruption through his sufferings from birth to the cross. Clement also presents the Logos as a Teacher, who during his parousia, interprets precisely the Old Testament, and in his appearing, discloses true gnosis, which guides anthropos to godliness. The evidence demonstrates that Clement bases his path for assimilation to God upon the Incarnation of the Logos.
