I’m working on a Philosophy multi-part question and need support to help me study.
(a) clearly identify the immediate inference as valid, invalid, or valid by limitation, and (b) provide the rationale for your assessment in terms of the squares of opposition and/or the operations of conversion, obversion, and contraposition. Be sure to pay special attention whatever effect existential import may have on the validity of the immediate inferences (#1-10)
Test the validity of each of the following categorical syllogisms using Venn diagrams. (1) When setting up each Venn diagram, please use the lower left-hand circle to represent the subject term of the conclusion and the lower right-hand circle to represent the predicate term of the conclusion. The upper circle should be used to represent the syllogism’s middle term. (2) Clearly identify the form of the syllogism using the indicated terms, and keep in mind that you may need to reduce terms, as explained in Section 6G, before diagramming. Any argument that results from the reduction of terms should include only the three terms indicated for the corresponding syllogism. Finally, (3) clearly indicate whether the argument is valid or invalid, and (4) explain your reasoning (#11-13)
