Entry 4

Item 1:

• Structure:

All cats have four legs ( All S is P)

I have four legs ( A is P)

-------------------------------------------

I am a cat ( A is S)

• Type of fallacy: Structural fallacy
• Analysis: The argument is invalid. Two premises are true; however the conlusion is false because of inference. In fact, there are many animals with 4 legs, are not cats such as: cows, buffaloes....

Item 2.

• Type of fallacy: Slippery slope
• Analysis: This argument is false because having more knowledge about cars doesn’t lead to the desire of having a BMW because BMW is not the greatest one among many famous brands of cars.

Item 3.

• Type of fallacy: False dilemma
• Analysis: The MasterCard advertisement suggests that there are two cases: something can’t not be bought by money and everything else  can be bought by a MasterCard. However; it’s clear that not everything can be bought with a MasterCard. Money cannot by everything and Neither can MasterCard.
