The Subject of Logic

Abstract: Any attempt to discover and delimit the domain of a science necessarily resolves itself into the determination of just what the science investigates, studies, and analyzes. But that about which a science conducts its investigation is called the subject of the science, as has already been explained.1 For “that is the subject in a science whose causes and properties we seek.”2 The investigation of the domain of logic, therefore, requires the accurate determining of its subject. In the texts distinguishing logic from metaphysics which have just been seen, much is said about the subject of logic. In other texts also among those already examined there are indications of what logic studies. The operations of reason, ens rationis, intentions, the mode of predication, and the true and the false have all been assigned to logic as the field of its endeavors. Each of these must be carefully examined to determine and delimit the domain of logic and discover exactly what St. Thomas considers to constitute the proper subject of this science.
