PAULEE'S philosophicalynessterdiest[=

TODAYYY IN MR.B.W. BASINGER'S CLASS WE..
discussed deductive reasoning..

there are three types of deductive logic which are Syllogisms, Modus Ponens, and Modus Tollens.

A Syllogism is a type of deductive reasoning where a major premise (which contains A term and B term) and minor premise (which contains B term and C term) combine to make a conclusion (which contains A term and C term).

here is an example:

Hip-hop singers beat up their girlfriend.
Chris Brown is a hip-hop singer.
Chris Brown beats up his girlfriend.


A Modus Ponens is a deductive reasoning where a "if p, then q" statement is given and "p" is given as a positive premise, so that we may be sure of the positive premise of "q".


here is a simple example:

If Michael Phelps wins 8 gold medals, then he will get caught smoking marijuana.
Michael Phelps won 8 gold medals.
Therefore, Michael Phelps did get caught smoking marijuana.

A Modus Tollens is a deductive reasoning where "if p, then q" statement is given and "q" is given as a negative premise, so that we may be sure of the negative premise of "p"


here is another simple example:

If michael jackson stayed away from little boys, then he would perform more shows.
Michael Jackson did not perform more shows.
Therefore, Michael Jackson did not stay away from little boys.
