Logic is about inference, which is a complex mental operation. Inference presupposes a simpler, more fundamental act--judgment. Judgment is still a complex mental that also presupposes a simpler, more fundamental act--simple apprehension or conception. Simple apprehension or conception generates the concept, which is verbally expressed as a term. From this, it should be clear that if we wish to thoroughly understand inference, we shall have to study more carefully the simpler mental operations and the products they involve.
The second part of our study is The Logic of Conceptions. It has three levels: Basic, Intermediate, and Advanced. The Basic level provides you with the nonnegotiable, essential knowledge about the logic of conceptions. Accomplishing this level moves you up to the next level. The Intermediate level provides knowledge necessary to pass this part of the course. Accomplishing this level opens up two possibilities for you: one possibility opened is that of moving on to the next unit of the course: The Logic of Judgments; another possibility opened is that of moving on to the next level. The Advanced level provides you with knowledge that is not necessary for passing the course on Logic, but is necessary to become a good student of Philosophy.
