Unwarranted Contrast


Logical Fallacy of Unwarranted Contrast / Some Are-Some Are Not

Unwarranted contrast is a formal fallacy that covers up the problem when reasoning is based on one of the three fallacies of Agrippa's trilemma. Whenever a logical fallacy is committed, the fallacy has its roots in Agrippa's trilemma. All human thought (without Divine revelation) is based on one of three unhappy possibilities. These three possibilities are infinite regress, circular reasoning, or axiomatic thinking. This problem is known as Agrippa's trilemma. Some have claimed that only logic and math can be known without Divine revelation; however, that is not true. There is no reason to trust either logic or math without Divine revelation. Science is also limited to the pragmatic because of the weakness on human reasoning, which is known as Agrippa's trilemma.

The Logical Fallacy of Unwarranted Contrast / Some Are-Some Are Not occurs when it is assumed that because some of one thing have a certain characteristic, then some of that thing must not have that characteristic or vice versa. 

INVALID FORM

“Some A are B. Therefore, Some A are not B.” “Some A are not B. Therefore, Some A are B.” 

There are times when you can only know about some people, places, or things. In those cases, you can observe those people, places, or things and make a statement that is true for all of them. Barring Divine revelation, you can only rationally make a statement about some. You cannot examine all, so you make a statement about some. If you have no evidence to show an exception, then you cannot assume that there is or is not at least one exception.

Examples of the Logical Fallacy of Unwarranted Contrast / Some Are-Some Are Not

"Some Christians follow Christ; therefore, some Christians don't follow Christ."

This conclusion is actually true. The logic, however, is faulty. We don't know that some Christians don't follow Christ because we know that some Christians do follow Christ. We know that some Christians don't follow Christ because some of those Christians make it obvious that they are not following Christ.

"All Christ-followers follow Christ sometimes; therefore, all Christ-followers don't follow Christ sometimes."

The logic is faulty, and the conclusion is not known.
