VICE-PRINCIPAL OF ST. EDMUND HALL, OXFORD.
The following ILLUSTRATIVE OBSERVATIONS were first published in the year 1816, and have been considerably enlarged in subsequent editions. The author vas disposed to allow them to continue out of print, knowing that several works of great utility have been more recently published on the same subject. He has, however, been influenced by repeated applications from various
quarters to issue another edition.
DE TERMINIS SIMPLICIBUS.
§. 1. De Mentis Operationibus. MENTIS operationes ad ratiocinandum adhibitæ tres sunt: 1. Simplex Apprehensio ; 2. Judicium ; 3. Discursus.
The office of Logic is the developement of the natural process of the human mind in the act of reasoning. It has therefore a close alliance with that branch of Metaphysics which relates to the faculties and operations of the mind. These faculties indeed, and their respective operations, are so diversified, that the enumeration of them might be carried to an almost unlimited extent. But, if not all, those at least with which Logic is connected, may be reduced to these three classes, Simple Apprehension, Judgment, and Reasoning. The act of Reasoning is, in fact, the subject matter of Logic; and to this the exercise of the other two operations are subordinate.
Each of these words, Simple Apprehension, Judg. ment, Reasoning, is employed to denote, first, the faculty or power of the mind; then, the operation or exercise of that faculty; and, lastly, the result of that operation.
