‘Sound is eternal because it is produced’ refers to which of the following…

Concept

A hetvābhāsa is an apparent reason that fails to establish a thesis. In the viruddha type, the reason does not merely fail; its established implication proves the opposite of the proposition to be established.

Application

The thesis says that sound is eternal, while the given reason says that sound is produced. Whatever is produced comes into existence and is therefore non-eternal. Thus, the reason supports the negation of the thesis rather than the thesis itself.

Contrast

• Bādhita concerns a reason whose conclusion is contradicted by stronger established knowledge, such as perception.

• Asiddha concerns a reason that is not established in the subject under discussion.

• Savyabhicāra concerns an irregular reason that occurs both where the probandum is present and where it is absent.

Result

Therefore, the fallacy is Viruddha.
