知識 and 知恵: Known information and practical judgment
Compare knowledge of local culture and a condition for calm judgment with ingenuity in using limited ingredients and solving a problem together.
Known content and a condition for judgment
知識 means knowledge. 「旅の前に現地の文化について知識を深めた。」 describes developing knowledge of the local culture before traveling.
「正しい知識があれば、落ち着いて判断できる。」 says accurate knowledge makes calm judgment possible. Preserve the condition rather than adding a completed judgment or a guarantee that every decision is correct.
Making use of ingredients and solving a problem
知恵 means wisdom or ingenuity. 「限られた材料を生かす知恵を祖母から学んだ。」 says the speaker learned from their grandmother how to make use of limited ingredients.
「皆で知恵を出し合い、問題を解決した。」 states that everyone pooled their wisdom and solved the problem. Read the learning source and the completed joint solution as the separate examples.
Information and its use in a situation
知識 emphasizes what is known. 知恵 emphasizes judgment or ingenuity suited to a situation. The knowledge example also connects knowledge with judgment, so it is not restricted to information that cannot be used in life.
知恵 can itself be learned from someone, as the grandmother example shows. Do not impose a rule that knowledge comes only from books and wisdom only from innate intuition or experience.
Does 知恵 in making use of limited ingredients refer only to the amount of information known about those ingredients?
Show the answer and why
No. It concerns judgment and ingenuity in using them. Compare this with the known content of 知識, while allowing overlap in their use and how they are learned.
