PRAMÂNA ARTHĀPATTI AND ABHĀVA
The first group comprising the four subtypes where a 'capacity' is posited are on the whole criticized not on the basis of some logical consideration but on the ontological consideration that the concept of 'capacity' is untenable.21 Jayanta's basic contention is that an effect is produced by a cause accompanied by the appropriate accessories but not possessed of a socalled 'capacity' supposed to be something supersensuous. » The Mimāṁsaka argues that a capacity' is to be posited for the following reasons :
(1) Otherwise, any thing might produce any thing inasmuch as all things are similar qua a substance;
(2) While under the influence of a spell a thing apparently remaining the same and remaining accompanied by the appropriate accessories fails to produce the effect concerned, and this happens because this thing is now deprived of the capacity' concerned;
