The thirteenth sutta of the Aṭṭhakavagga of the Suttanipāta.

Philosophers praise only themselves and their own views, and disparage others. Their disputations cannot lead to purity. The true brahmin is he who has overcome all disputes and is confident in his knowledge. He is indifferent to learning, for he is calm and peaceful (SN.vss.895-914).

The sutta was one of those taught on the occasion of the Mahāsamaya (SNA.ii.557), and is specially recommended for those inclined to confusion of mind (moha-carita). MNidA.222.
