A few months ago, in the 5781 שבת שובה Toras Avigdor booklet (p.6-7), Rav Avigdor Miller ז"ל addressed some dangerous distortions in Torah study and teaching, that exist among some Torah students and teachers, including, unfortunately, some identified with the Litvishe community, that can lead to Torah impoverishment and alienation, G-d forbid.
In particular, two distortions were described.
1) Covering too little ground. Getting bogged down in a Talmudic thicket, and not getting to know the vast, beautiful forest around it. It is very important to have context, to get the proverbial big picture, in Torah as in life, for proper understanding, and one doesn't get that from a relative few pages.
Rav Avigdor Miller states emphatically, based on his experience in great ישיבות of the past, that learning Torah does not mean learning merely the first six blatt of a מסכת, albeit with "all rishonim and achronim" in a winter zman. Rather much more was learned. As Rav Miller states, essential Torah principles and wisdom are not limited to the most widely studied pages of Talmudic tractates, but rather appear throughout the vast Talmudic sea (ים התלמוד). And through the תוה"ק in general, of course.
2) Skipping "non-lomdish" sections of gemara. Rav Miller speaks harshly of a rebbi he once had, that, when they came to sections of the Talmud that were not "legalistic", but rather dealt with חכמה, מוסר, eitzos, and yiras shamayim, he would skip them (!).
A wholesome Torah education leads to a wholesome Torah personality. A fragmented and piecemeal Torah education can lead (G-d forbid) to a deficient, semi-educated, fragmented, immature product.
As the saying goes, a little knowledge is a dangerous thing.
May Hashem help us learn and grow appropriately.
