From Douglas Moore’s Art of Quotation blog
“The peculiar evil of silencing the expression of an opinion is, that it is robbing the human race;
posterity as well as the existing generation; those who dissent from the opinion, still more than those who hold it. If the opinion is right, they are deprived of the opportunity of exchanging error for truth: if wrong, they lose, what is almost as great a benefit, the clearer perception and livelier impression of truth, produced by its collision with error. “
~John Stuart Mill, On Liberty, 1859, English, economist, philosopher, writer

A salutary warning but I’m not optimistic it will be heeded.
These are dark times.
Yes, I agree. I hope the terror we’ve been experiencing will shake us all to the core and realize that we all must vote and participate in our democracy. No one can afford to just be silent ever again. Wake up, folks!!
I think -clearer perception is right for benefit for humanity.dear leonardo !!m i right saying?
Agree.
