People thus differ from animals, which want without limit. Precisely because people's desires can be ordered according to reasoned principles, and can be structured so that they do not clash, each individual's will is not internally contradictory, and desires can be harmonized and co-exist.
正因為人的意志會「要」得合於思維的律則，會「要」得不自相矛盾，所以各個人的意志也才能「要」得彼此不相矛盾、「要」得彼此和諧並存。
