The contentious impulse [nitzachon] cannot bear truth. And even if a true matter is clarified before its eyes — it will push it away because of contentiousness. Therefore one who truly wants the truth must first remove the attribute of contentiousness. And then one can see the truth if one wishes. But Hashem Yisborach — even in His "nitzachon" [triumph] He is truth. And this is: ""and also the Eternity [Netzach] of Israel will not lie"" [I Samuel 15:29]. [From this you will see with a broad eye: many things that some of the greats of the generation innovated — and the spirit of the sages of their generation was not pleased with them — that this is no proof at all to say: if it were true — why was it not accepted in the eyes of the sages of the generation? For according to what is explained here — the attribute of contentiousness cannot bear truth — and this applies to all mortal beings — and only Hashem Yisborach is praised in it. Therefore the Sifri said on the verse ""and you shall not answer in a dispute"" — ""al rav"" [about a superior] — do not say: I will do as he says without reason and proof.]
