وثالثها: التسمية، أعني عنوان العلم
The third heading is its designation: the science's title or name.
A title identifies the discipline under which discussions are organized. “Manṭiq” is the familiar name under which conception, judgment, syllogism, and fallacies are studied.
Knowing the name does not itself define the subject. It helps identify the field, while its subject and aim specify what the name encompasses.
