Talbott 12 # 42 Fall 2019 Dear Friends, One problem we constantly come up against in our work here at the Institute The Nature Institute has to do with the differences between our own human experience and the meaningful activities we try to describe in other organisms. Those activities STAFF include purpose-like behavior and the cognitive aspects of perception. How can Craig Holdrege Henrike Holdrege we characterize such activities in a paramecium or elephant without reading, or Elaine Khosrova seeming to read, features of our own behavior and perception into organisms Kristy King very unlike us? Judith Madey Veronica Madey In her article on the restoration of bald eagles in this issue, Henrike indirectly Stephen L. Talbott alludes to the problem when she remarks: “It is not so easy to be aware of and Adjunct Researchers/Faculty concerned about the disappearance of creatures less conspicuous than the Bruno Follador emblematic bird, such as many amphibians, reptiles, fish, insects, spiders, song Jon McAlice birds, and more.” What are the reasons that we come to value and rally behind Marisha Plotnik Vladislav Rozentuller certain creatures, while we attend to others—regardless of their ecological Nathaniel Williams significance—much less? Johannes Wirz Craig faces the problem of anthropomorphism in one of its more extreme Board of Directors forms when he asks, “Do Flowers Hear Bees?” — except that in this case we are Siral Crane not speaking of anthropomorphism proper: Craig Holdrege Henrike Holdrege I’ve noticed in the literature a tendency to animalize plants as a means of Marisha Plotnik Jan Kees Saltet giving them more credence as “substantial” beings on earth that we should Signe Schaefer be more aware of and care for. But this is not at all necessary. Plants are Jeffrey Sexton remarkable creatures in their own ways. We don’t need to analogize them with Nathaniel Williams animals, which scientists do when they refer to “neurobiology” in plants. Board of Advisors Will Brinton And Steve comes up against this problem in a yet different way when he Gertrude Reif Hughes discusses the “purposive” character of life. In his feature article, he writes that Wes Jackson Andrew Kimbrell the activity of proteins in the human body is “graceful, artistic, purposive, and Fred Kirschenmann meaningful.” This is not language typically used when describing molecules, and Johannes Kühl yet — given all the research findings — it seems much more suitable than all George Russell the talk of “molecular mechanisms” that are supposed to make life happen.
