Over the previous three posts I’ve sketched out a high-level map of a conceptual landscape. The terrain we’ve been looking at, and for which we now have a very broad overview suitable for orienting our inquiry, is comprised of a set of interrelated ideas that together make up the modern energy concept. In other words, we’ve created our map not by looking directly at the physical phenomena to which the energy concept relates but by looking at the conceptual structures that others have developed on the basis of their own immediate encounter with physical phenomena and the perceptions that arose for them with these experiences. This is not to say that our map is not based on direct encounters with the particular terrain we’ve depicted—it’s just that the encounters are of a very different nature. The direct encounters upon which our map is based, rather than being of a physical nature, have their origin in the social realm of language and culture. The map represents a set of ideas already in widespread social circulation—and so the landscape it deals with is one comprising concepts formed and expressed in language.
