Phenomenology, particularly as developed by Merleau-Ponty, primarily concerns how human beings perceive and act towards the world they encounter, their lifeworld. Umwelt theory, by contrast, primarily concerns the animal lifeworld, which is also the concern of Biosemiotics. Exploring the overlap between the two disciplines requires a fuller understanding of how human perception has evolved to become so very different from that of animals. This article will try to provide that and show how that may help to address the ecological crisis (...) surrounding us. Human beings now develop and live in in a world where most of what they encounter are cultural artefacts. In fact, as Simondon suggests, human beings and technological objects are co-evolving. This has brought about radical changes in the way we relate to the natural world. But these are not necessarily changes for the better. Indeed, McGilchrist claims that the last thousand years or so of cultural evolution has profoundly impaired how human beings attend to the world. This paper will suggest that this impairment has contributed to the ecological crisis we now face, and that to help meet it both Biosemiotics and Umwelt theory should take more account of the revival of interest in panpsychism as seen in the work of Goff and others.
