| Abstract: | Some philosophers—indeed, a large number—have presented us with a picture of human knowledge which makes it problematic as to whether we can ever be acquainted with an objective world. Given the nature of perception and thought as characterized by, e.g., Descartes and Hume, there is a problem about how anything I can be aware of can have any sort of objective status; there is a problem of how my awareness of anything can amount to anything other than its merely seeming to me that things are thus and so. And of course many of these same philosophers, and other philosophers, have tried in all sorts of different ways to counter this skeptical thrust. Some, like Descartes, have argued that although human perceiving and human thinking are themselves purely subjective affairs, nevertheless the content of some of our thoughts and ideas is such that it (the content) could not exist if there did not also exist certain things of a quite objective nature. Another way of putting Descartes' thesis is to say that although all our concepts of things are, as concepts, purely subjective entities, nevertheless the content of some of our concepts requires that there exist certain objective entities. |
