Full Idea
Although truth and falsehood are properties of beliefs, they are properties dependent upon the relations of the beliefs to other things, not upon any internal quality of the beliefs.
Gist of Idea
Truth is a property of a belief, but dependent on its external relations, not its internal qualities

A Reaction
Beliefs can have an intrinsic property of subjective certainty, but Russell is right that that is not enough. So is truth a property or a relation?
