Medicine, as Byron Good argues, reconstitutes the human body of our daily e
xperience as a "medical body,'' unfamiliar outside medicine. This reconstit
ution can be seen in two ways: (i) as a salutary reminder of the extent to
which the reality even of the human body is constructed; and (ii) as an are
na for what Stephen Toulmin distinguishes as the ``intersection'' of natura
l science and history, in which many of philosophy's traditional (and tradi
tionally abstract) questions are given concrete and urgent form. This paper
begins by examining a number of dualities between the medical body and the
body familiar in daily experience. Toulmin's epistemological analysis of c
linical medicine as combining both universal and existential knowledge is t
hen considered. Their expression, in terms of attention, respectively, to n
atural science and to personal history, is explored through the epistemolog
ical contrasts between the medical body and the familiar body, noting the t
raditional philosophical questions which they in turn illustrate.
