Antirazor

An antirazor is an argument in informal logic stating that if an explanation is too simple to explain the evidence, then one must develop a more complex solution. It is a opposed to Occam's razor.

Various antirazor arguments have been made.

Antirazor Arguments
The most famous antirazor is "Chatton's antirazor." Walter of Chatton was a contemporary of William of Ockham (1287–1347) who took exception to Occam's razor and Ockham's use of it. In response he devised his own anti-razor: If three things are not enough to verify an affirmative proposition about things, a fourth must be added, and so on.

Anti-razors have also been created by Immanuel Kant (1724–1804), and Karl Menger (1902-1985). Kant felt a need to moderate the effects of Occam's razor and thus created his own counter-razor: The variety of beings should not rashly be diminished.

Karl Menger found mathematicians to be too parsimonious with regard to variables so he formulated his Law Against Miserliness which took one of two forms: Entities must not be reduced to the point of inadequacy. It is vain to do with fewer what requires more.
