Seridei Aish Key to learning Torah is challenging Sages who are presumed to be correct

Daas Torah page 193

Seridei Aish (1:113): I frequently comment on the apparent contradiction found in Avos (6:5) concerning those factors involved in acquiring Torah i.e. analysis of the students and faith in our Sages. Furthermore, what does faith in our Sages have to do with acquiring Torah? However, the explanation is that if one doesn’t believe in the truth of the words of the sages then one readily dismisses them for the slightest reason. With an attitude of condescension, one proclaims that they didn’t know what they were talking about. Consequently, one makes no effort to investigate and try to validate what they said. However, in the end we find that in fact we are the ones who have erred. … Therefore it is characteristic of the truly wise to presume that the sages have not erred, G-d forbid! In fact we, with our limited perspective and limited understanding, have erred. On the other hand to blindly believe and not struggle to comprehend with our intellect the apparent difficulties, saying simply that they knew and we need merely to mindlessly rely on them, that is also not correct. We need to wrestle mightily with the apparent contradictions and doubts as if they are people like us. With this approach, we will come to a much profounder and sharper comprehension. Thus, we see that both factors - emunas chachomim (faith in our sages) and pilpul (intellectual evaluation) - work together to the purpose of the acquisition of Torah.
