Full Idea
To explain belief in what is false we shall have to regard what is called belief in a proposition as not a thought related to the proposition, but rather as a thought related to the constituents of the proposition.
Gist of Idea
To explain false belief we should take belief as relating to a proposition's parts, not to the whole thing

A Reaction
Russell proposed a new theory of judgement, in order to explain erroneous judgements, given that true propositions are identical with facts. Of course there might be errors about the constituents, as well as about their structure. Othello is his example.
