4.116 Everything that can be thought at all can be thought clearly. Everything that can be put into words can be put clearly. In order to be able to represent logical form, we should have to be able to station ourselveswith propositions somewhere outside logic, that is to say outsidethe world. What finds its reflection in language, language cannot represent. What expresses itself in language, we cannot express by means of language.
Propositions show the logical form of reality.
They display it. What can be shown, cannot be said. The simplest kind of proposition, an elementary proposition,asserts the existence of a state of affairs. A proposition is an expression of agreement and disagreementwith truth-possibilities of elementary propositions. 4.41 Truth-possibilities of elementary propositions are the conditions of the truth and falsity of propositions.
