CC Madhya 25.55

parama kāraṇa īśvara keha nāhi māne
sva-sva-mata sthāpe para-matera khaṇḍane
Word for word: 
parama kāraṇa — the supreme cause, the cause of all causes; īśvara — the Supreme Lord; keha nāhi māne — none of the above-mentioned philosophers accept; sva-sva-mata — their own personal opinions; sthāpe — they establish; para-matera khaṇḍane — busy in refuting the opinions of others.
Translation: 
“Of the philosophers mentioned, none really cares for the Supreme Personality of Godhead, the cause of all causes. They are always busy refuting the philosophical theories of others and establishing their own.
