an.10.116 Aṅguttara Nikāya (Numbered Discourses)

With Ajita

Then the wanderer Ajita went up to the Buddha, and exchanged greetings with him.
When the greetings and polite conversation were over, he sat down to one side and said to the Buddha,
“Master Gotama, we have a spiritual companion called ‘The Philosopher’.
He has worked out around five hundred arguments by which followers of other paths will know when they’ve been refuted.”
Then the Buddha said to the mendicants,
“Mendicants, do you remember this philosopher’s points?”
“Now is the time, Blessed One! Now is the time, Holy One!
Let the Buddha speak and the mendicants will remember it.”
“Well then, mendicants, listen and pay close attention, I will speak.”
“Yes, sir,” they replied.
The Buddha said this:
“Mendicants, take a certain person who rebuts and quashes unprincipled statements with unprincipled statements. This delights an unprincipled assembly,
who make a dreadful racket:
‘He’s a true philosopher! He’s a true philosopher!’
Another person rebuts and quashes principled statements with unprincipled statements. This delights an unprincipled assembly,
who make a dreadful racket:
‘He’s a true philosopher! He’s a true philosopher!’
Another person rebuts and quashes principled and unprincipled statements with unprincipled statements. This delights an unprincipled assembly,
who make a dreadful racket:
‘He’s a true philosopher! He’s a true philosopher!’
Mendicants, you should know bad principles and good principles.
And you should know bad results and good results.
Knowing these things, your practice should follow the good principles with good results.
So what are bad principles? What are good principles? What are bad results? And what are good results?

And the many bad, unskillful qualities produced by wrong view are bad results.
And the many skillful qualities fully developed because of right view are good results.
