SN 12:15 Kaccayanagotta Sutta states:
By & large, Kaccayana, this world is supported by (takes as its object) a polarity, that of existence & non-existence. But when one sees the origination of the world as it actually is with right discernment, 'non-existence' with reference to the world does not occur to one. When one sees the cessation of the world as it actually is with right discernment, 'existence (atthitañceva)' with reference to the world does not occur to one. 'Everything exists': That is one extreme. 'Everything doesn't exist': That is a second extreme. It's to this extent, Kaccayana, that there is right view.
MN 60 Apannaka Sutta states:
...this venerable person is still criticized in the here-&-now by the observant as a person of bad habits & wrong view: one who holds to a doctrine of non-existence.'
...this venerable person is still praised in the here-&-now by the observant as a person of good habits & right view: one who holds to a doctrine of existence (atthikavādo).'
My reading of these two suttas gives an impression of a contradiction. MN 60 appears to state the 'doctrine of existence' ('atthikavādo') is right view. But SN 12.15 appears to state the 'view of existence' ('atthitañceva') is wrong view.
Is this a contradiction? If so, what is the cause, what is the reason, for this?
