How to unify knowledge. Keynote address

The central question of general scholarship is whether all of knowledge is intrinsically consilient, that is, whether it can be united by a continuous skein of cause-and-effect explanation and across levels of increasingly complex organization. The answer lies in the recognition that the traditional line separating the great branches of learning (natural sciences, social sciences, and humanities) is not a barrier or even a line, but rather a broad domain of poorly explored material phenomena now being cooperatively entered from all sides. The key to bridge-building is the discovery and analysis of human nature, which consists of the epigenetic rules--the hereditary regularities in mental development. Their study is now well under way, at the biological, social science, and humanities levels. Examples of epigenetic rules include the origin of color vocabularies, incest avoidance, optimum arousal in artistic design, and response to the natural environment. The convergence of the great branches of learning is mostly an empirical process, light on formal logic and theory in its initial stages. The value of the consilience program is that at long last we appear to have acquired the means either to establish the intrinsic truth of the fundamental unity of knowledge, or to discard it. I will argue the likelihood of its existence and early establishment.
