Foolishly arrogant as I was, I used to judge the worth of a person by his intellectual power and attainment. I could see no good where there was no logic, no charm where there was no learning. Now I think that one has to distinguish between two forms of intelligence, that of the brain, and that of the heart, and I have come to regard the second as by far the more important. I guard myself against saying that intelligence does not matter ; the fool is ever as noxious as he is wearisome. But assuredly the best people I have known were saved from folly not by the ⓐ________ but by the ⓑ______. They come before me, and I see them greatly ignorant, strongly prejudiced, capable of the most absurd errors in reasoning ; yet their faces shine with the supreme virtues : kindness, sweetness, modesty, generosity. Not only do they possess these qualities, but they also understand how to use them ; they have the intelligence of the heart.

ⓐ ⓑ
① rationality―heart
② heart―intellect
③ heart―rationality
④ intellect―heart
⑤ intellect―rationality
