An example of this is the use of the rules of inference found within symbolic logic. Aristotle held that any logical argument could be reduced to two premises and a conclusion. [2] Premises are sometimes left unstated, in which case, they are called missing premises, for example: Socrates is mortal because all men are mortal.
From the example above, humans, mortal, and Greeks: mortal is the major term, and Greeks the minor term.

The first type of enthymeme is a truncated syllogism, or a syllogism with an unstated premise. [6] Here is an example of an enthymeme derived from a syllogism through truncation (shortening) of the syllogism: "Socrates is mortal because he's human."

In everyday reasoning, the fallacy of four terms occurs most frequently by equivocation : using the same word or phrase but with a different meaning each time, creating a fourth term even though ...
Not all shows have stuck to their original premise over the years — in fact some changed their central story lines on purpose. Family Matters is a great example since it shifted its cast. The ...
Examples: The column-14 operator (OR), shows Addition rule: when p=T (the hypothesis selects the first two lines of the table), we see (at column-14) that p∨q=T. We can see also that, with the same premise, another conclusions are valid: columns 12, 14 and 15 are T.
