Caution is the theme of what looks fine usually isn’t. Almost every language has a proverb for it, and the choice of image gives away the worldview behind the warning.
The Khmer choose a forest with a snake. The Russians choose a quiet whirlpool with devils in it. The English settle for a rose and its thorn — a softer, almost romantic register. The Spanish, in their cheerful fatalism, say that everywhere they cook beans: trouble is universal, so make peace with it.
What unites these proverbs is the observation. What separates them is the temperament. Caution, it turns out, is not one mood. It’s a family of them.
