Some things in life we can prove to be true; some things we know to be true; and some things we accept to be true. Things we accept become beliefs. A desideratum is a powerful belief, a tool by which we guide our passage through life. When difficult decisions must be made after all facts have been assessed, the desiderata of our lives guide how we proceed. Naturalists cope with the interface between humanity and nature, a confrontation sometimes elegant, sometimes hostile. These are a naturalist's desiderata, the tools by which humanity can survive nature and nature can survive humanity. Series presented by Kevin Cook. The session for March is "Tolerate the Unlikeable". Wasps and cockroaches are easy to scorn, as are cowbirds and house mice. But life is not a marketplace of aesthetics from which to pick those you like and reject those you dislike. Life is a package. This becomes the naturalist's quest: tolerate the unlikable.
