Logical fallacies are errors made in reasoning.
Reasoning is the process of either inducing or deducing a conclusion from any given set of data. In the case of deductive reasoning, one reasons from a set of premises to a conclusion. If the premises are true, and the logic is correct, the conclusion is indisputable. In the case of inductive reasoning, one reasons from a set of data to a conclusion. If the data is true and the logic reasonable, the conclusion may not be accepted as a truth, for the conclusion is an assumption based on experience.
