“without sense or reason”
“Why you need a reason for everything? Reason is something people say to make sense of things that don't make sense.”
“Look, if the reason you two aren't speaking doesn't make sense, then the reason you contact him again doesn't have to make sense, either. If nothing makes sense, act accordingly.”
“Upon my word, Emma, to hear you abusing the reason you have, is almost enough to make me think so too. Better be without sense than misapply it as you do.”
“It is a thousand times better to have common sense without education than to have education without common sense.”
“Emotion without reason lets people walk all over you; reason without emotion is a mask for cruelty.”
