I have really hard time swallowing the Conditional Reasoning section from PowerScore.
On page 116 of Logical Reasoning Bible it says...
"The sufficient condition does not make the necssary condition occur. "
"occurrence of the sufficient condition is a sign or indicator that the necessary cnodition will occur"
and on next page....
someone receiving an A+ (Sufficient) is a sign that indicates that studying(Necessary) must also have occurred.
A+ (Sufficient) does not make the studying (Necessary) occur
In sum, does the sufficient condition make the necessary condition occur or NOT!!!?
Sufficient and necessary/conditional relationships do not NECESSARILY entail cause and effect. Conditional relationships are in large part different than cause and effect relationships, however, there is some overlap between the two types of basic logic.
With conditional relationships, the truth of the sufficient condition guarantees the truth of the necessary condition, logically speaking, but that does not mean that the occurrence of the sufficient condition caused the necessary condition to be true. One conditions truth REQUIRES the other to be true, but that does not mean that the sufficient condition came first and caused the necessary to be true. The order the two conditions became true in time (temporally) can go either way. It's just a matter of logical truth. If you know that A is true, then you can conclude that B is true, but absent other context or subject matter stuff the established relationship tells you nothing about causal or temporal relationships between the conditions.
