Ben Sira 21:18

18 To an ignorant person, wisdom is as useless as a house gone to ruin. He has never even thought about the things he is so sure of.

Ben Sira 21:18 In-Context

16 Listening to a foolish person talk is like traveling with a heavy load on your back, but it is a pleasure to hear what intelligent people have to say.
17 The assembly will be eager to hear from an intelligent person and will take his opinion seriously.
18 To an ignorant person, wisdom is as useless as a house gone to ruin. He has never even thought about the things he is so sure of.
19 To a person without any sense, an education is like handcuffs,
20 but to a sensible person, it is like gold bracelets. An intelligent person will smile quietly while a fool roars with laughter.
