Deductive Fallacy

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 regression, circular reasoning, or axiomatic thinking. This is known as Agrippa's trilemma. Some have claimed that only logic and math can be known; however, that is not true. Without Divine revelation, neither logic nor math can be known. Science is also a casualty of the weakness on human reasoning, which is known as Agrippa's trilemma.

The Deductive Fallacy occurs when any fallacy of deductive reasoning is committed. This is a very broad term that would include all deductive fallacies. Deductive fallacies are those fallacies where it is claimed that the premises provide absolute proof that a conclusion is true, but the premises do not absolutely prove that the conclusion is true.

Keep in mind that for deductive reasoning to be sound, the premises must be true. That means that the reasoning on which they rest cannot be dependent on any arbitrary assumptions.

Inductive reasoning is reasoning that shows that something might be true. Deductive reasoning is reasoning that absolutely proves that something is true.

Examples of the Deductive Fallacy

Fallacies of Presumption, Bare Assertion, and Lies (using no evidence at all)
Fallacies of Flawed Evidence (using evidence that isn't true or testable by anyone)
Fallacies of Limiting Presuppositions (Worldviews or presupposed assumptions severely limit the ability to perceive reality or to discern between reality and the presuppositions/worldview.)
Fallacies of Contradiction
Fallacies of Comparison
Fallacies of Choice
Fallacies of Cause
Fallacies of Circular Reasoning (Assuming the conclusion as a starting point for proving the conclusion)
Fallacies of Non Sequitur (Using evidence that doesn't prove the point)
Fallacies of Invalid Form (Formal Fallacies: Getting mixed up in thinking)
Fallacies of Ambiguity (being unclear)
Relevance Fallacies of Authority (using authority as evidence when the authority doesn't prove the point)
Relevance Fallacies of Emotion (using emotion rather than reason)
Relevance Fallacies Against the Person, Organization, Book, etc. (attacking people rather than reasoning)
Relevance Fallacies of Pressure (using pressure rather than reason)
Relevance Fallacies of Distraction/Misdirection (Causing the focus of attention to move to one thing in order to avoid detection of another thing)
Fallacies of Omission (leaving out important information)
Tactics and Mind Games (using deceptive tricks of various kinds that go beyond statements)
Faulty Conclusions That Affect Future Reasoning (They become part of the inner paradigm or presupposition and are not challenged again because they are thought to be part of reality.)
