Wilhelm Dilthey used the example of understanding a sentence as an example of the circular course of hermeneutic understanding. He particularly stressed that meaning and meaningfulness were always contextual. Thus the meaning of any sentence cannot be fully interpreted unless we know the historical circumstances of its utterance. And this means that interpretation is always linked to the situation of the interpreter, because one can only construct a history from the particular set of circumstances in which one currently exists. Thus Dilthey says: "Meaningfulness fundamentally grows out of a relation of part to whole that is grounded in the nature of living experience." For Dilthey, "Meaning is not subjective; it is not projection of thought or thinking onto the object; it is a perception of a real relationship within a nexus prior to the subject-object separation in thought."
