The importance of philosophy in the origins debate, in addition to empirical science, is underscored. This is done first by outlining some historically older philosophical issues in the areas of epistemology and ontology which allowed for the subsequent acceptance of modern day evolutionism. Secondly, the effect of some of these views on thought in general and in relation to some aspects of biology, physics and origins in particular is examined. Finally, the nature of the origins debate and the limits of science are considered. It is concluded that the origins debate do involve questions of philosophy and that empirical science alone cannot resolve the issue.
