VAN DER WALT, Barend J. The world-picture of the reformed biologist, Jan Lever (1922-2010) from an evolutionary theory towards an evolutionistic faith?. Koers (Online) [online]. 2016, vol.81, n.1, pp.1-8. ISSN 2304-8557.  http://dx.doi.org/10.19108/koers.81.1.2253.

Evolution as a theory is today proclaimed widely, accepted by many as a fact and is often reflected even in South Africa in prescribed textbooks for schools and universities. The main question to be discussed in this reflection is whether the idea of evolution always remains a mere theory. Does it not often, even unintentionally, eventually develop into an evolutionistic faith or worldview and thus would become to Christians an unacceptable worldview? Different contemporary secular thinkers openly acknowledge the dependence of their theory of evolution upon an agnostic or an atheistic faith and/or, vice versa, their evolutionary theory leading toward unbelief. Some Christian-reformed natural scientists (1) clearly rejected the hypothesis of evolution, including an evolutionistic worldview. Others (2), again including those from the reformed Christian tradition, are of the opinion that, after God (before time) created everything, reality unfolded or developed under His guidance. In the case of a third group of (3) Christian evolutionary scientists it seems as if the compromise or synthesis which they tried to achieve between their Christian convictions and their scientific hypotheses could not be achieved. Finally they had to choose in favour of the one or the other. A first article (cf. Van der Walt, 2016a) already discussed these varying and even clashing viewpoints among Christians. It focussed on the position of an earlier, well-known reformed theologian from the Netherlands (Abraham Kuyper) and a South African Christian philosopher (Hendrik Stoker). A second contribution on the same issue (cf. Van der Walt, 2016b) shifted attention to the viewpoints of three biologists from the reformed Christian circle, viz. Harry Diemer, Duyvené de Wit and Jan Lever. The first two of them may be regarded as representatives of position (2) above, while the third initially belonged to (2) but after about 1970 gradually developed towards (3). The present article follows Lever's thinking from about the seventies up to 2010. An increasing tension developed between his Christian belief in the Bible, and God as Creator and his zoological research according to an evolutionary paradigm. It gradually becomes evident that he ascribed such weight and even revelationary power to his scholarly results that it eventually clashed and overpowered his Christian worldview, replacing it with an evolutionistic world-picture or even a (semi-)evolutionistic worldview.
