“The majority never has right on its side.”
Act IV
Flertallet har magten — desværre —; men retten har det ikke. Retten har jeg og de andre få, de enkelte. Minoriteten har altid retten. http://books.google.com/books?id=3VcqAAAAYAAJ&q=%22Flertallet+har+magten+desv%C3%A6rre+men+retten+har+det+ikke+Retten+har+jeg+og+de+andre+f%C3%A5+de+enkelte+Minoriteten+har+altid+retten%22&pg=PA134#v=onepage
The majority has the might — more's the pity — but it hasn't right. I am right — I and one or two other individuals like me. The minority is always right. http://books.google.com/books?id=Vl0Xb4lPL5IC&q=%22The+majority+has+the+might+more's+the+pity+but+it+hasn't+right+I+am+right+I+and+one+or+two+other+individuals+like+me+The+minority+is+always+right%22&pg=PA96#v=onepage
An Enemy of the People (1882)
Context: Dr, Stockmann: It is the majority in our community that denies me my freedom and seeks to prevent my speaking the truth.
Hovstad: The majority always has right on its side.
Billing: And truth too, by God!
Dr. Stockmann: The majority never has right on its side. Never I say! That is one of those social lies against which an independent, intelligent man must wage war. Who is it that constitute the majority of the population in a country? Is it the clever folk or the stupid? I don't imagine you will dispute the fact that at present the stupid people are in an absolutely overwhelming majority all the world over. But, good Lord!— you can never pretend that it is right that the stupid folk should govern the clever ones! [the crowd cries out] Oh yes— you can shout me down, I know! But you cannot answer me. The majority has might on its side-unfortunately; but right it has not. I am in the right— I and a few other scattered individuals. The minority is always in the right.
