PHILOSOPHICALINVESTIGATIONS 1145
Of course we have the right to use an assertion sign in contrast with a question-
mark, for example, or if we want to distinguish an assertion from a fiction or a supposi-
tion. It is only a mistake if one thinks that the assertion consists of two actions,
entertaining and asserting (assigning the truth-value, or something of the kind), and that
in performing these actions we follow the propositional sign roughly as we sing from
the musical score. Reading the written sentence loud or soft is indeed comparable with
singing from a musical score, but ‘meaning’ (thinking) the sentence that is read is not.
Frege’s assertion sign marks the beginning of the sentence.Thus its function is
like that of the full-stop. It distinguishes the whole period from a clause withinthe
period. If I hear someone say “it’s raining” but do not know whether I have heard the
beginning and end of the period, so far this sentence does not serve to tell me anything.
- But how many kinds of sentences are there? Say assertion, question, and com-
mand?—There are countlesskinds: countless different kinds of use of what we call
“symbols,” “words,” “sentences.” And this multiplicity is not something fixed, given
once for all; but new types of language, new language-games, as we may say, come into
existence, and others become obsolete and get forgotten. (We can get a rough pictureof
this from the changes in mathematics.)
Here the term “language-game” is meant to bring into prominence the fact that
the speakingof language is part of an activity, or of a form of life.
Review the multiplicity of language-games in the following examples, and in others:
Giving orders, and obeying them—
Describing the appearance of an object, or giving its measurements—
Constructing an object from a description (a drawing)—
Reporting an event—
Speculating about an event—
Forming and testing a hypothesis—
Presenting the results of an experiment in tables and diagrams—
Making up a story; and reading it—
Play-acting—
Singing catches—
Guessing riddles—
Making a joke; telling it—
Solving a problem in practical arithmetic—
Translating from one language into another—
Asking, thanking, cursing, greeting, praying.Imagine a picture representing a boxer in a particular stance. Now, this picture can be
used to tell someone how he should stand, should hold himself; or how he should not
hold himself; or how a particular man did stand in such-and-such a place; and so on.
One might (using the language of chemistry) call this picture a proposition-radical. This
will be how Frege thought of the “assumption.” [Note added by Wittgenstein.]
—It is interesting to compare the multiplicity of the tools in language and of the ways
they are used, the multiplicity of kinds of word and sentence, with what logicians
have said about the structure of language. (Including the author of the Tractatus
Logico-Philosophicus.)
