Wittgenstein frequently uses the word 'aspect' (Aspekt) in his writing
s from 1947 to 1949. There he uses the word along with aspect-seeing a
nd aspect-change, so that readers are misled into thinking his primary
concern in using the word is something like Gestalt psychology or phi
losophy of psychology per se. However, Wittgenstein's late treatment o
f aspect is only a special case of a more general problem, namely phen
omenology. In the middle-period writings, the word 'aspect' refers to
a phenomenological object. Basically, Wittgenstein's aspect means the
way an object appears to us. For him, an 'aspect' is a phenomenologica
l object.
