This article builds on my previous article on Dirk H. Th. Vollenhoven (Ive 2015) and provides an overview of the development of the systematic philosophy of Herman Dooyeweerd. This article seeks to provide an overview of the key developments in the thinking of Dooyeweerd, both in the convergences arising from the conversation of the two brothers-in-law and long-term colleagues and in their divergences. Dooyeweerd and Vollenhoven worked within the tradition of Abraham Kuyper, the father of Reformational philosophy. The development of (...) their respective philosophical systematics has tended to be addressed separately. However, I argue that the close cooperation between the two philosophers was critical in the formulation of the philosophy of the cosmonomic Idea. The philosophical conversation between the two persisted, despite critical divergences, largely aired privately. Their respective insights remained a source of mutual stimulus and complementarity foundational for Reformational philosophy. (shrink)

Philosophy gives an account of our experience 1. Philosophy does not begin with rational propositions or presuppositions, but rather with our experience. Dooyeweerd begins A New Critique of Theoretical Thought by contrasting the continuity of our pre-theoretical experience with the way that theoretical experience splits apart this continuity.1 He says later, “The apriori structure of reality can only be known by experience. But this is not experience as it is conceived by immanence-philosophy.”2 Human experience is not limited to our temporal (...) functions of consciousness.3 Our experience is not an ‘Erlebnis’ of mere psychical feelings and sensations,4 but rather “a conscious enstatic5 ‘Hineinleben.’” — the experience of our supratemporal selfhood enter ing into and living within all aspects of temporal reality.

This essay analyzes the view of evolution of Jan Lever (1922–2010), founder of the biology department at the Vrije Universiteit Amsterdam, and compares his view with those of J.H. Diemer and H. Dooyeweerd. Together with Dooyeweerd, Lever wrote a series of chapters on the species concept inPhilosophia Reformata(1948–1950) in which species were defined as constant types. In his book,Creatie en Evolutie(1956), Lever still subscribed to Dooyeweerd’s philosophy but also suggested that it is possible that biological evolution occurred, including that of (...) human beings, and that scientific research can shed light on these processes. Influenced by his idea of individuality structures, Dooyeweerd criticized Lever and suggested that species are constant; that science cannot speak to the topics that Lever discusses. It is argued that Dooyeweerd’s views are influenced by the typological thinking of the time and that reformational thought would benefit from de-emphasizing this aspect of reformational philosophy.
