This is the specific character of analogy - there is some likeness of meaning, but more unlike than like. Only one term is truly health and this is known as the principal analogate. The other analogates are only secondary and take their significance from the principal analogate, for they are not health itself. A juicy steak when you're hungry is good. A dog is good.
Justice is good.
A man is good. God is good. This example differs from that of analogy of attribution. Here there is not one principal analogate, but the term is said truly, though diversely, of all the subjects. They have something in common.
