Christian philosophy of dynamic development


 Welcome to the website of Marinus Dirk (Dick) Stafleu


I am the author of a number of books and papers dealing with my philosophy of dynamic development. This is the fruit of a life long study of Herman Dooyeweerd's and Dirk Vollenhoven's Christian philosophy of the cosmonomic idea.

Born 1937, I studied physics and mathematics at the University of Leyden before I became a research fellow at the Radboud University, Nijmegen, earning my PhD in experimental physics in1967. When lecturing physics, philosophy of science and history of physics at the teacher training institute of the Hogeschool Utrecht, I was involved as project manager in several local and national projects. Since my early retirement in 1998 I am a full-time philosopher.


On this site you will find the text of several books: 


Time and again (1980, 2014): my first book, now available on-line.

Theory and experiment, Philosophy of science in a historical context (2016) is the epistemological and historical counterpart of Time and again. It is a revised version of Theories at work, On the structure and function of theories in science, in particular during the Copernican revolution (1987). 

Mathematical foundations of quantum physics (2014) discusses the natural relation frames and characters.

The open future, Contours of a Christian philosophy of dynamic development (2016, revised 2017) is a short and informal essay, serving as a concise introduction.

Nature and freedom (2018) discusses the history of natural philosophy and theology during the Enlightenment and Romanticism. (A Dutch translation is available.) 

A strong state and a strong civil society (2018) presents my political philosophy.

Encyclopedia of relations and characters (second edition, 2018) is an overview of my philosophy. Except for Time and again it replaces  Laws for dynamic development (2015), which, however, is still available. Encyclopedia I is concerned with natural relations and characters, Encyclopedia II with normative ones. Many lemmas in this encyclopedia are copied from the other books on this site.

Studies in the philosophy of evolution and history is a collection of published papers and book chapters, written between 1986 and 2018.

All these texts are also available on PDF, free of charge.
