Abstract
Praxis, Language, Dialogue Human engagement with the world develops and evolves into increasingly social, complex, and explicit modes. This essay examines the evolution of meaningful human engagement from simple embodied activity, to language-less social praxis, and then to praxis incorporating increasingly rich forms of linguistic action, culminating in theory. Each mode of meaningful engagement creates a space in which new modes of meaning can develop. These new ways of experiencing, acting, and communicating create their own meaning contexts, which provide the settings for the further evolution of humans' phenomenological, hermeneutic, and practical involvements. Each mode of meaning gives rise to its successors, allowing humans to acquire new powers to understand and manipulate their environments and each other. This increase and refinement of human power raises ethical issues that we address using the Gadamerian concept of dialogue.
