28. Preliminary Note. -- The orderly arrangement of science is accomplished in a progressive way.
First, the predicate is formally connected with the subject: an act of judgment.
Then, being brought together and combined, the judgments produce more complex judgments: reasoning.
Lastly, several reasonings relating to the same object contribute to the formation of a logical system: organization of science.
Chapter III will consist of three articles corresponding to the three stages of logical order.
Article I, devoted to the study of the judgment and the proposition, will be divided into three sections:
§ 1. Meaning of the judgment and the proposition.
§ 2. Judgments and propositions.
§ 3. Relations between judgments and propositions.
