Frege's view that in an assertion there is contain[e|s]d a supposal Annahme, and that it is this

which
that

is asserted, is based really on the possibility that there is in our language o[r|f] writing every

Ts-226,14

every assertion sentence in the form: “It is asserted that so and so is the case”. But “that so and so is the case” is not a sentence in our language –

this
it

is not ˇyet a move in our language game. And if I write insetad of “It is asserted that …”, ˇI write “It is asserted: so and so is the case”, then in this case the words “It is asserted” are quite superfluous.
We might very well write every assertion in the form of a question followed by an affirmative reply; thus instead of “It's is raining”, “Is it raining? Yes.”. Would that show that in eve[er|ry] assertion there is contained a question?
