'There
is only one kind of ugliness that cannot be presented in conformity
with nature without obliterating all aesthetic liking and hence
artistic beauty: that ugliness which arouses disgust. For in that
strange sensation, resting on nothing but imagination, the object is
presented as if insisted, as it were, on our enjoying it even though
that is just what we are forcefully resisting; and hence the artistic
presentation of the object is no longer distinguished in our
sensation from the nature of this object itself, so that it cannot
possibly be considered beautiful'
