WALKER, Joseph A.  and  CLOETE, Thomas E.. Reductionism or holism? The two faces of biology. Herv. teol. stud. [online]. 2023, vol.79, n.1, pp.1-7. ISSN 2072-8050.  http://dx.doi.org/10.4102/hts.v79i1.8336.

Reductionism and holism, that is, antireductionism, are two of the prevailing paradigms within the philosophy of biology. Reductionists strive to understand biological phenomena by reducing them to a series of levels of complexity with each lower level forming the foundation for the subsequent level, by mapping such biological phenomena inasmuch as possible to the principal phenomena within the fundamental sciences of chemistry and physics. In this way, complex phenomena can be reduced to assemblages of more elementary explananda. Holism, in counterpart, claims that there independently exist phenomena arising from ordered levels of complexity that have intrinsic causal power and cannot be reduced in this way. When dealing with the nature of biology and its unique foundations of essentialism, determinism and ethics, the pedagogical lens through which these foundations are conveyed to learners could provide a limited perspective if only the reductive approach is followed as it would not sensitise learners to the true complexity of the phenomenon of life and the study thereof, and it is the purpose of this article to frame the reductionist-antireductionist debate in order to illustrate this. CONTRIBUTION: This article contributes new knowledge to the field of the philosophy of science; more specifically, the philosophy of biology by critically evaluating the pervasive dialectic between the theoretical frameworks of reductionism and antireductionism and alluding to the pedagogical consequences thereof

Keywords : reductionism; holism; antireductionism; determinism; essentialism; biology.
