For good is considered in the light of something desirable, while being and true are not so considered: because good is "what all things seek."

Context

“Thomas quotes the passage, probably from memory, as though it were an assertion: "I am become," etc.] I answer that, Good, true and being are the same in reality, but differ as considered by reason. For good is considered in the light of something desirable, while being and true are not so considered: because good is "what all things seek." Wherefore good, as such, cannot be the object of hatred, neither in general nor in particular. Being and truth in general cannot be the object of hatred: because disagreement is the cause of hatred, and agreement is the cause of love;” source
