What did Sherlock Holmes mean when he said, "Love is too emotional and incompatible with the reason I respect very much"?

Rationality, that is, rational thinking or behavior, is usually a correct judgment, and feelings usually affect this rational judgment. In ancient China, there was a fable called "Even a wise man sometimes nods". There was a rich man in Song State. When it rained heavily, the wall of his house was broken. The rich man's son said, "If you don't build it, thieves will steal it." The old man next door said the same thing. Rich people really lost a lot of things at night. As a result, the rich man thought his son was very clever, but he suspected that the old man in the neighborhood had stolen from his family. This is the result of emotion, the same thing, the same words, and different judgments are caused by the intimacy of the relationship. Therefore, emotions usually lead to wrong judgments, while rational thinking is usually correct, so they are incompatible.
