Explanation : In Viruddha hetvabhasa or contradictory
fallacious reason, the middle term abides in
the minor term as well as in its opposite. It is a
reason uniformly concomitant with a contrary
inference as well, which means, it proves
the contrary of what it is intended to prove.
e.g. In "Air is heavy because it is empty",
the middle term 'empty' actually disproves
the heaviness of air. Similarly, in 'Sound is
element, because it is caused', the middle
term, 'caused' actually disproves that sound
is element because element is a naturally
occurring thing rather than 'caused'.
