parts of every assertion as well as to most, if not all other
sentences. But I need only notice assertions. You are
familiar with assertions, and you will not, at present, need
to know very exatly what they consist of. It will suffice to
point out a few obvious characters. In the first place, they
belong to that class of signs which can be Uttered, i.e. that one can
either scribe (i.e., write, or draw, or typewrite, or print on a visible surface) or sound by a person whom I designate the Utterer. This, however,
does not mean that the assertion itself, as I mean the word, can
be rendered visible or audible, since in my sense the very
same assertion can be both scribed and sounded; and it may
be sounded over and over again in different keys, sometimes
in a whisper, some time shouted through a megaphone, and can
be scribed in black ink, in red, in blue, or with pencils of many color.
