Rav Shach did not think very highly of books about the world view of Torah [השקפה]. He brings the verses that criticize making books "of making books there is no end" עשות ספרים אין קץ, and the end of that verse shows it is all vanity and a waste of time. On the other hand he brings statements that are indicative that books on Torah are important.
The resolution is books that continue the process of the Oral Law are good. Books that try to get world view issues are a waste. "Give a philosopher enough paper, and he can prove anything."
[However what would Rav Shach say about the Guide for the Perplexed or the Faiths and Doctrines of Rav Saadia Gaon? Apparently he would have to agree that a certain limited amount of this kind of study is important.]
