Throughout much of his writing, Whitehead outlines a critique of what he termed the `bifurcation of nature'. This position divides the world into objective causal nature, on the one hand, with the perceptions of subjects on the other. On such a view, truth lies in a reality external to such subjects and it is the task of science to deliver clear and immediate access to this realm. Further, judgments about this external reality are the province of human subjects and it (...) is the task of philosophy to ascertain the validity or otherwise of these. This article outlines Whitehead's attempts to develop a conception of nature which avoids this premise; it also explains how he offers a way for contemporary theories to construct or engineer abstractions which go beyond notions of social construction or deconstruction. This article argues that not only does Whitehead offer a coherent alternative to such approaches but that the manner in which his major text is written reflects his commitment to the inherently constructed and constructing character of all existence.
