makes itself manifest. The world is my world: this
is manifest in the fact that the limits of language (of that language
which alone I understand) mean the limits of my world.

5.621 The world and life are one.

5.63 I am my world. (The microcosm.)

5.631 There is no such thing as the subject that thinks or entertains
ideas. If I wrote a book called The World as l found it, I should have
to include a report on my body, and should have to say which parts were
subordinate to my will, and which were not, etc., this being a method of
isolating the subject, or rather of showing that in an important sense
there is no subject; for it alone could not be mentioned in that book.--

5.632 The subject does not belong to the world: rather, it is a limit of
the world.

5.633 Where in the world is a metaphysical subject to be found? You will
say that this is exactly like the case of the eye and the visual field.
But really you do not see the eye. And nothing in the visual field
allows you to infer that it is seen by an eye.

5.6331 For the form of the visual field is surely not like this

5.634 This is connected with the fact that no part of our experience is
at the same time a priori. Whatever we see could be other than it is.
Whatever we can describe at all could be other than it is. There is no a
priori order of things.

5.64 Here it can be seen that solipsism, when its implications are
followed out strictly, coincides with pure realism. The self of
solipsism shrinks to a point without extension, and there remains the
reality co-ordinated with it.

5.641 Thus there really is a sense in which philosophy can talk
about the self in a non-psychological way. What brings the self into
philosophy is the fact that 'the world is my world'. The philosophical
self is not the human being, not the human body, or the human soul, with
which psychology deals, but rather the metaphysical subject, the limit
of the world--not a part of it.

6. The general form of a truth-function is [p, E, N(E)].

This is the general form of a proposition.

6.001 What this says is just that every proposition is a result of
successive applications to elementary propositions of the operation N(E)

6.002 If we are given the general form according to which propositions
are constructed, then with it we are also given the general form
according to which one proposition can be generated out of another by
means of an operation.
