If two standard form categorical propositions with the same subject and predicate are related in such a manner that if one is undetermined the other must be undetermined, what is their relation?
If two standard form categorical propositions with the same subject and predicate are related in such a manner that if one is undetermined the other must be undetermined, what is their relation? Correct Answer Sub-altern
The standard form of categorical proposition having the same subject term and predicate term but may differ from each other in quality or quantity or both. Such differing has been called opposition. The term opposition is used when there is no apparent disagreement between the propositions.
This happens in sub-altern (A+I or E+O). Consider following:
Subalternation: It is the opposition between a universal proposition and its corresponding particular proposition. In the corresponding proposition, the universal proposition is called superaltern and the particular proposition is called subaltern. These propositions have the same subject and predicate term and agree in quality. Both are affirming or both denying but differ in quantity. On universal and the other particular.
For Example-
- All citizens are taxpayers (A)
- Some citizens are taxpayers. (I)
- If some citizens are taxpayers is true, then difficult to come up with a single venn diagram
- in that situation, the universal positive (A) will be undetermined because we can’t draw a single venn diagram.
Therefore, the relation between two standard form categorical propositions with the same subject and predicate are related in such a manner that if one is undetermined the other must be undetermined is - Sub-altern.
