Appeal to tradition:
|When a claim is deemed true on the basis that it has a long-standing tradition behind it.||Polygamy is wrong because marriage here in our country has long been only between one man and one women.|
|All traditional practices were at one time new. The duration of a practice neither validates or invalidates the practice. Patricide, child sacrifice and self-immolation were all well-established traditions at one time, yet are now generally abhorred.|
Case Study One
Both extremes on the issue of public nudity have invoked this fallacy to justify their positions.
Keep in mind that a fallacious argument does not entail an erroneous position.
