A judgment is a mental act by which one makes a resolution to adhere to a proposition as true, with all its logical consequences.
Do we not all perceive that judgment is something closely allied to assertion? That is the view that ordinary speech entertains. A man or woman will be heard to use the phrase, “I says to myself.” That is, judgment is held to be either no more than an assertion to oneself or at any rate something very like that.
A proposition […] is not to be understood as the lingual expression of a judgment. It is, on the contrary, that sign of which the judgment is one replica and the lingual expression another. But a judgment is distinctly more than the mere mental replica of a proposition. It not merely expresses the proposition, but it goes further and accepts it.
A judgment is a mental act deliberately exercising a force tending to determine in the mind of the agent a belief in the proposition; to which should perhaps be added that the agent must be aware of his being liable to inconvenience in the event of the proposition’s proving false in any practical aspect.

A mental proposition is called a judgment.
