Herman Dooyeweerd, Dutch philosopher and scholar (b. 1894)
Herman Dooyeweerd (7 October 1894, Amsterdam – 12 February 1977, Amsterdam) was a professor of law and jurisprudence at the Vrije Universiteit, Amsterdam from 1926 to 1965. He was also a philosopher and principal founder of Reformational philosophy with Dirk Vollenhoven, a significant development within the Neocalvinist (or Kuyperian) school of thought. Dooyeweerd made several contributions to philosophy and other academic disciplines concerning the nature of diversity and coherence in everyday experience, the transcendental conditions for theoretical thought, the relationship between religion, philosophy, and scientific theory, and an understanding of meaning, being, time and self.

Dooyeweerd is most famous for his suite of fifteen aspects (or 'modalities', 'modal aspects', or 'modal law-spheres'), which are distinct ways in which reality exists, has meaning, is experienced, and occurs. This suite of aspects is finding application in practical analysis, research and teaching in such diverse fields as built environment, sustainability, agriculture, business, information systems and development. Danie Strauss, the editor of Dooyeweerd's Collected Works, has provided a systematic look at Dooyeweerd's philosophy here.
