The power of an idea is never to be underestimated. Many a thought has survived long after its host has ceased to be. It is the power of an idea that no shield can defend against, nor sword divide, nor poison infect. As such, we must aspire to create ideas, rather than preserve life. In a sense, this is how we achieve true immortality and live on past our time.

Meaning: The rhyme presents a spring ague as medicine fit for a king. It gives a feverish illness a surprising positive value rather than simply treating it as misfortune.

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.
