Sattler, R.

Rolf Sattler FLS FRSC (born 8 March 1936) is a Canadian plant morphologist, biologist, philosopher, and educator. He is considered one of the most significant contributors to the field of plant morphology and "one of the foremost plant morphologists in the world." His contributions are not only empirical but involved also a revision of the most fundamental concepts, theories, and philosophical assumptions. He published the award-winning Organogenesis of Flowers (1973) and nearly a hundred scientific papers, mainly on plant morphology. As well he has contributed to many national and international symposia and also organized and chaired symposia at international congresses, edited the proceedings of two of them and published them as books. Besides Biophilosophy (1986), his philosophical contributions include articles on complementarity (perspectivism), process philosophy, the mandala principle, and the convergence of science and spirituality. Additional publications deal with holistic alternative medicine and healing ways of thinking such as fuzzy logic, Yin-Yang thinking (both/and logic), and Buddhist and Jain logic.
