 Such Delphic self-knowledge should carry over to our assessment of knowledge secured by modern science, as well. For, as Gadamer puts the point, “when a naïve faith in scientific method denies the existence of effective history, there can be an actual deformation of knowledge” (Gadamer, Truth and Method, 301). This is evident first of all from the humanistic study of the history of science. After all, knowledge based on the best results of science today may well have the same fate as the discredited scientific knowledge of past times. It is also evident that we should carry over Delphic self-knowledge to our assessment of scientific knowledge from the fact that scientific inquiry is always guided by more prejudice than can be kept in check by any method: for example, in the selection of research questions, in hypothesis formation, and in any number of metaphysical (or other) assumptions tacitly or unconsciously used to characterize objects of inquiry.
