 Regarding matters that can be known from scripture, claims are not to be established by reasoning. This is because reasoning—when uninformed by scripture and based only on human imagination—lacks stability; for such imagination is unconstrained. Moreover, even when experts prepare arguments by employing imagination with care, such arguments may appear unsound to others who have greater expertise. Given that arguments imagined up by someone may later appear unsound to another, arguments cannot acquire any stability due to human disagreement. (Shastri 1980: 366–367)
