This is the Intermediate level in the study of the Logic of Judgments. Here we study the two ways we do immediate inference: the reformulation of attributive propositions into equivalent propositional forms through the processes of eduction and the relationship of propositions to one another as to truth and falsity--how, if one proposition is true, certain other propositions must be false, and vice versa" (Bachhuber, 53) through the processes of opposition.
The first part, good for one week, has 5 lessons: 1) The Quantity, or Extension, of the Predicate (pp. 34-9); 2) Conversion (pp. 55-60); 3) Obversion (pp. 60-4); 4) Contraposition (pp. 64-9); and 5) Inversion (pp. 69-71).
This level (part II), good for two weeks, has six lessons: 1) Contradictory Opposition (pp. 75-8, 81); 2) Contrary Opposition (pp. 78-9, 81); 3) Subcontrary Opposition (pp. 79-80, 81); 4) Subalterns (pp. 80-1); 5) The Square of Oppositions (pp. 74-5; 81-4), and 6) Immediate Inference (pp. 53, 84-5).
Alongside the reading activity, there are three types of activities in this unit. Quizzes will help you understand the ideas you encounter. Reflection activities will help you consolidate your thoughts. A discussion with the class will help deepen your insights.
Successful completion of this level and of The Logic of Conceptions: Advanced Level will unlock the The Logic of Judgments: Advanced Level.
