 In all these cases it seems clear that debates about reductionism in biology have not reached a denouement but rather portend vigorous philosophical discussion as the heterogeneity of issues related to its ontological, epistemological, and methodological types are brought to bear on perennial biological topics. The task of philosophers focused on reductionism in biology will be to analyze these promiscuities of reasoning and seek to develop accounts of reduction that capture what scientists actually do and contribute to more general perspectives on biological knowledge and scientific inquiry.
