The fundamental tenet of contemporary sociobiology, namely the assumption of a single process of evolution involving the selection of genes, is critically examined. An alternative multiple-level, multiple-process model of evolution is presented which posits that the primary process that operates via selection upon the genes cannot account for certain kinds of biological phenomena, especially complex, learned, social behaviours. The primary process has evolved subsidiary evolutionary levels and processes that act to bridge the gap between genes and these complex behaviours. The (...) subsidiary levels are development, individual animal learning, and socioculture itself. It is argued that individual learning is pivotal to the derivation and biological analysis of culture. The differences between cultural and noncultural societies are stressed. It is concluded that such a multiple-level model of evolution can form the basis for reconciling opposing sides in the sociobiology debate. (shrink)

Bringing together evolutionary biology, psychology, and philosophy, Henry Plotkin presents a new science of knowledge, one that traces an unbreakable link between instinct and our ability to know.

What credentials does evolutionary epistemology have as science? A judgement based on past performance, both in terms of advancing an empirical programme and further ng theory construction, is not much. This paper briefly outlines some of the research areas, both theoretical and empirical, that can be developed and that might secure for evolutionary epistemology a future in evolutionary biology.

There is a close coincidence in time between the appearance of psychology as a science and the rise of evolutionary theory. The first laboratory of experimental psychology was established in Germany by Wilhelm Wundt just as Darwin's writings were beginning to have their enormous impact, especially as they might be applied to understanding the human mind . Psychology is an important discipline because it straddles the boundary between the biological sciences and the social or human sciences of anthropology, sociology and (...) economics. Given that importance, and given that new sciences lack the conceptual history within which older, established sciences might be mired, it might have been expected that psychology would have embraced in a way that established sciences did not the equally new, sensational and central theorem of biology which spoke to the origins of species as well as the origins of their traits and, crucially, the functions of those traits. Yet for over a century evolutionary theory had virtually no presence in psychology, despite having powerful friends like William James at court. (shrink)

There is a close coincidence in time between the appearance of psychology as a science and the rise of evolutionary theory. The first laboratory of experimental psychology was established in Germany by Wilhelm Wundt just as Darwin's writings were beginning to have their enormous impact, especially as they might be applied to understanding the human mind (Darwin, 1871). Psychology is an important discipline because it straddles the boundary between the biological sciences and the social or human sciences (defined as those (...) sciences that study exclusively human characteristics) of anthropology, sociology and economics. Given that importance, and given that new sciences lack the conceptual history within which older, established sciences might be mired, it might have been expected that psychology would have embraced in a way that established sciences did not the equally new, sensational and central theorem of biology which spoke to the origins of species as well as the origins of their traits and, crucially, the functions of those traits.

'Necessary knowledge' tackles one of the big questions - what knowledge do we possess at birth, and what do we learn along the way? It neither sides with those who believe in 'blank slate' theories, nor with those who believe all learning is innate. Instead, it proposes an original new solution to this enduring puzzle.

Many of the commentaries cohere around two major points of criticism. The first is that we have omitted discussion of the mechanisms that are assumed to operate at levels 2, 3, and 4.Campbell, Cloak, Dewsbury, Eckberg, Mundinger, Pulliam, Richerson & Boyd, Slobodkin, Simon, Williams, andWahlstenall make comments that bear on this point. The second point is that we have omitted discussion of the fact that "organisms change the environment by their activities" and thereby modify the selection pressures that act on (...) them. Apart from Lewontin, this point has been raised in different forms byBarkow, Chase, Hull, Perzigian, Ruyle, and less directly bySlobodkin. Stemming from these two basic omissions there is a third general criticism. Numerous commentators have pointed out that we have failed to discuss sufficiently either the extent or nature of the constraints that may or may not be operating on supraordinate evolutionary processes as a function of their nested relationships to subordinate evolutionary processes within our scheme. We start by acknowledging these three basic omissions. We agree that they exist and that they are serious. (shrink)

One of the oldest and most fundamental distinctions and disputes of classical epistemology is that between the rationalists and empiricists. In recent decades, partly due to the increasing influence of evolutionary thought in psychology, the argument has become central in cognitive science as well, but it will remain empirically intractable until further advances occur in neurogenetics, neuroscience, and how these tie in to fundamental psychological mechanisms and processes.
