false belief

There are people who believe that in the matter of learning poetry there is no "ought," but this is a false belief.

An idea that she had disjointed the whole framework of things by creating a false belief filled her imagination.

More complete confusion of this false belief is nowhere to be found than in these "Fragments."

And yet by the crimes to which that false belief led them they almost proved the truth of something very like it.

They spring, like moral cowardice and anger, from the false belief that this little self of ours is of very great importance.
