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 Leiden before I became a research fellow at the Radboud University, Nijmegen, earning my PhD in experimental physics in 1967. When lecturing physics, philosophy of science and history of physics at the institute for teacher training 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, which I started November 2015, you will find the text of several books and papers: 


Time and again (1980) was my first book. I revised it in 2016..

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.

Chronos & Clio, Time in history (2012) is the translation of Chronos & Clio, De tijd in de geschiedenis (2011). It discusses the relation of the concepts of time and history in the perspective of the philosophy of dynamic development. 

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, Philosophy of nature, Natural theology, Enlightenment and Romanticism (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 (to be published) 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.

Essays on normative principles and characters is a collection of papers published between 2003 and 2014.


Because each page of this website is more or less self-contained, several texts or text fragments appear on more than one page. 

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