Question

I would be glad to know how you understand the contribution of the "Tzemach Tzedek" of Chabad to the discussion of matters of faith and knowledge.
I am asking specifically about him because, unlike Chabad Hasidic books in general, and the broader teachings of Hasidism in particular, which do not deal with the subject directly, one could say that he took up the challenge and discussed these issues in a systematic and orderly way, apparently trying thereby to represent the Hasidic method, whose footprint in the realm of intellectual discussion is supposedly lacking. (In his books Sefer HaChakira, which as its name indicates is devoted to these topics, and Derekh Mitzvotecha in the commandment of belief in God and the commandment of the unity of God, which appear to be profound and wide-ranging essays.)
(I had difficulty phrasing the question precisely. I am not expecting you to lay out for me some kind of systematic summary of his views and main arguments, and I understand that the question is general, for which I apologize in advance. But if you could nevertheless do that, or something along those lines, I would be deeply grateful.)
