Novelists would do well to remember that when the works of the scholar-historians create doubt in the researcher’s mind, the researcher then turns to literature as a primary source for confirmation or correction. If the truth of a time, a people, a state is not available anywhere else, let it be in the novel. - from Twayne’s US Authors Series: JOHN A WILLIAMS by Gilbert Muller

Editorial context: This metaphor criticises refusal to consider evidence. Visual disability is not unwillingness to understand, and disagreement alone does not prove refusal.

Meaning: Someone who refuses to consider available evidence may resist understanding more than someone who lacks information. The saying criticises deliberate avoidance, but its sight metaphor must not equate visual disability with unwillingness or ignorance.

Meaning: The phrase offers having a bone in one’s arm as an explanation. Without its conversational setting, it does not say which action the speaker is avoiding or describing.

Meaning: A difficult day can cast a shadow over the evening that follows. The saying expresses how trouble carries on in experience, but its word never is an exaggeration: later rest, support or a change of circumstances can still help.
