== Informal Logic ==

The art of [[rhetoric]] is sometimes called "informal logic", and the classic [[logical fallacies|fallacies]] are often described as "logical fallacies", though, strictly speaking, most of them are simply emotionally effective ways to build an invalid argument.  Generally speaking, "informal logic" consists of "common sense" and a collection of other rather loose rules that people employ while making most decisions and even in debate. It is unstructured, and depends largely on one's view of "the reasonable". The thresholds of what is "reasonable" and what is not are inexact and subject to change with the receipt of sufficient contrary evidence – and again, what constitutes "sufficiency" in this context might vary from person to person.
