Here I use his thought to structure a logical framework from which to discuss ecological simulation models in a way that captures how these dynamic representations describe a world from which we can draw logical inferences about real-world ecological processes. I argue that Wittgenstein＇s Tractatus Logico-Philosophicus provides a way of reading problems that arise in using simulation as a way to make inferences about the world. Conversely, ecological simulation provides an illustration of a Tractarian system, because the digital world it creates completely describes and is defined by the programing language. This reading is a novel, but productive, way that notes that the language used in modeling requires a hermeneutical approach to make inferences about modeling/real-world relationships.展开更多
