“If all mankind minus one, were of one opinion, and only one person were of the contrary opinion, mankind would be no more justified in silencing that one person, than he, if he had the power, would be justified in silencing mankind.”

Meaning of “If all mankind minus one, were of one…”
Mill makes the number of people holding an opinion irrelevant to their right to silence dissent: minority speech remains worth protecting even when nearly everyone else believes it wrong.
Where does it come from?
On Liberty, Chapter II, Project Gutenberg #34901. Mill’s next argument is epistemic as well as political: suppressing an opinion can deprive everyone of truth or of the clearer understanding created when truth is tested against error.
