It is widely acknowledged that hoping is an integral part of what it is to be human. The present article strives to make sense of the myriad competing conceptions of hope that have emerged over the past half-century. Two problems with the literature are highlighted. First, discussions of hope tend to take place within rather than between disciplines. Second, hope is often taken to be an undifferentiated experience. In order to address the first problem, the article takes an interdisciplinary approach, drawing on research from the fields of philosophy, anthropology, psychology, theology and politics. In order to address the second problem, the article proposes that hope be regarded as a human universal that can be experienced in different modes. A variety of theories and models of hope are discussed, including those offered by Marcel, Dauenhauer, Bloch, Moltmann, Bovens, Pettit, Snyder, Rorty and Gutiérrez. While many of these claim to have identified the characteristics of hope, it is argued that each captures something about a particular mode of hoping. The theories and models are integrated into a framework comprising five modes of hoping: patient, critical, estimative, resolute and utopian. Examining hope in this way, as a human universal that can be experienced in different modes, may help us see the varying conceptions that presently exist within the human sciences not as conflicting, nor even as competing, but rather as complementary.
