The formation of anthropological knowledge in the Early Modern Age arose from the interaction of the disciplines of psychology, anatomy, physiology and natural law which set up a fundamental discourse on the nature of man from the Renaissance until the late Enlightenment. With this, the image of what people saw as human 'nature' underwent a change. It was now based on insights into the links between man's biophysical and mental structures, which produced imagination and memory and empowered him to act morally and to produce 'culture'.
