Logical Fallacy of Contradictory Premises

The contradictory premises fallacy is one of the many smokescreens that are used to cover the fact that the 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 contradictory premises occurs when a statement contradicts itself.

Examples of the Logical Fallacy of Contradictory Premises

"If God can do anything, can He make a stone so heavy that He won't be able to lift it?"

The premises are contradictory. God cannot be irrational, evil, unjust, or lie. He is what He is and that doesn't include being or doing irrational things. Note that, for the most part, people don't fully spell out their logic. In this case, a question was asked, and that doesn't appear to be a statement that would be required for logic. However, this is an old question that is used to try to show the non-existence of God. Stated more openly it would go something like this: If the God of the Bible exists, then He can do anything. If God can do anything, then He can make a stone so heavy that He won't be able to lift it. However, He can do anything, so He will be able to lift it. Therefore, the idea of God is irrational and the God of the Bible doesn't exist. The problem is not that God is irrational. The person using this ploy is irrational.

"I don't believe something written in a book" [meaning the Bible, which never needs to change]", but I believe in science" [meaning the constantly changing information in the science text books].
