This paper takes up the cause of species pluralism. An argument for species pluralism is provided and standard monist objections to pluralism are answered. A new form of species pluralism is developed and shown to be an improvement over previous forms. This paper also offers a general foundation on which to base a pluralistic approach to biological classification.

Anticipating a future theory of change, this paper comments on the phenomenon of anticipations in Dooyeweerd’s systematic philosophy. The idea that reality itself or human experience of reality has some kind of a layered structure is put forward by several philosophers, but the insight that each aspect refers intimately to the others is uniquely Dooyeweerdian. It concerns an essential property of the structure of the modal aspects, each of which displays a ‘meaning nucleus’, expressive of its original meaning, besides retrocipations (...) and anticipations, referring to the other aspects. Dooyeweerd assigns the aspects a linear temporal order, hence the distinction between retroand anticipations. In fact, each aspect is considered to be an aspect of time as well as an aspect of being, a mode of human experience, and a principle of scientific explanation. (shrink)

The aim of this paper is to investigate the transition in natural science from the search for the essence of matter to the search for the laws to which matter is subject. Starting about 1600, this transition meant a change of perspective, the introduction of a new metaphysical view of the world. A scientific worldview has at least four components, its ontology, epistemology, logic and heuristic, which I shall discuss with respect to the idea of natural law.
