The author argues that is not obvious what it means for our beliefs
and assertions to be "truth-directed," and that we need to weaken
our ordinary notion of a belief if we are to deal with radical
scepticism without surrendering to idealism. Topics examined also
include whether there could be alien conceptual schemes and what
might happen to us if we abandoned genuine belief in place of mere
pragmatic acceptance. A radically new "ecological" model of
knowledge is defended.
