Step 1: Understanding the Question
The question asks if "mere words of mouth" are sufficient to convey the full meaning of the "danger" associated with debt, according to the passage.
Step 2: Analyzing the Passage
The passage begins by stating that the proverb "Out of debt, out of danger" is wise, but then it qualifies this statement.
It says, "...but the word 'danger' does not sufficiently express all that the warning demands."
Later, it adds, "But as example is at all times more instructive than mere words of mouth...".
Step 3: Synthesizing the Answer
The passage clearly states that the word 'danger' is insufficient.
It then contrasts "mere words of mouth" with a real "example" (from a living writer), stating that the example is "more instructive".
This implies that words alone are not enough to convey the true gravity of the situation.
Step 4: Final Answer
The passage argues that personal examples are more effective than just words, indicating that mere words of mouth are not enough to express the full danger of debt.
