Was Maimonides Always Correct?

The Sefer HaBris (1:2:6) in a discussion about the structure of the heavens disagrees with the opinion of Maimonides. He then writes as follows:

It perplexes me that many people are of the opinion that everything written in the works of the Rambam must be correct. That nothing can be added or subtracted from it, and to say the opposite is impossible. The truth is that he did not come up with the truth is every case, and in many cases what he writes is the opposite of the truth. This is well documented by many prominent Jewish Sages in their holy works. I am a poor person before his honor, like a mustard seed before a full world. Everyone knows that he stands alone and there is no one who can compare to him among the Jewish sages in wisdom, science and Torah all of which he incorporated. No one taught Halacha  and the Mitzvos as he did. Still, despite the fact that everyone bows before his Yad HaChazakah there are things in it which we don't rule by. Surely that is true in other areas.

Some say that the development of philosophy was retarded because of the greatness and fame of Aristotle. Wise people generation after generation studied  his ideas and assumptions with the idea that anyone who would argue with Aristotle is disputing the absolute truth. The development of our belief system has been retarded for the same reason. Many think that disputing the Rambam is like disputing the absolute truth. This is essentially the same situation was with Aristotle and, interestingly, the Rambam based much of his teaching on Aristotle. But any person, even while loving the Rambam, should love the truth more.
