REQUIRED Forum Post # 4: Examples of Arguments (Evaluative Vocabulary)
Each apprentice is appropriate to contribute one post containing one example for anniversary of the afterward categories: (1) one accurate deductive argument, (2) one invalid deductive argument, (3) one valid, complete deductive argument, (4) one valid, ailing deductive argument, (5) one strong, cogent anterior argument, (6) one strong, uncogent anterior argument, (7) one weak, anterior argument. Students will not be able to see alternative students’ posts until she/he has posted. One's examples charge be original, novel, not from the textbook. Anniversary apprentice will accept a absolute of seven (7) altercation examples. The archetype arguments may accept any cardinal of premises, admitting one to three bounds will apparently be best. Acutely characterization anniversary archetype (e.g., “valid, ailing deductive argument”), and use Logical/Inference Indicators to acutely authenticate which account is the conclusion. After posting, anniversary apprentice is REQUIRED to animadversion on at atomic one alternative student's examples: are they correct? Are there any errors? Et cetera.
Following are examples for analogy ONLY:
Deductive, Accurate Argument
1. All schmucks are ducks.
2. All ducks are pucks.
3. Therefore, all schmucks are pucks.
Deductive, Invalid Argument
1. Maria is a hypochondriac.
2. Hence, Maria is abashed of dragons.
Comment: This is a deductive-definition/meaning argument. This altercation is invalid because if one supposes P1 is true, again the C does not necessarily follow. In alternative words, the appellation “hypochondria” does not beggarly “afraid of dragons.”
Deductive, Valid, Complete Argument
1. All dogs are mammals.
2. All mammals are animals.
3. Therefore, all dogs are mammals.
Comment: This altercation is deductive-categorical syllogism. Both Ps are true. The C is true. The altercation is complete because both P1 and P2 are true. This altercation is accurate because the C follows necessarily from the Ps.
Deductive, Valid, Ailing Argument
1. All dogs are mammals.
2. All mammals are fish.
3. Consequently, all dogs are fish.
Comment: P1 is true. P2 is false. The C is false. The altercation is accurate because IF the Ps are true, again the C necessarily follows. So, this altercation is deductive-categorical syllogism, valid, ailing because P2 is false.
