On the other hand I had today an eye opening experience which indicates to me that Musar if fact goes along way in giving people a basic idea of the total world view of the Old Testament along with a good summary of the basic practices that the Old Testament involves. I.e. how it would apply to people in a modern framework.
Maybe I should make a quick list of the Musar I found helpful in case anyone wants it for reference.: Yesod Veshoresh Haavoda, Chovot Levavot, the 8 chapters of the Rambam on Avot, Shaari Teshuva, Maalot Hamidot, Sefer Hayashar attributed to Rabbi Tam, Reshit Chachma. and the major disciples of Israel Salanter: Madragat Haadam [Joseph Horwitz from Novardok, Simcha Zisel from Kelm and Isaac Blasser from Petersberg. His book, Or Israel is a masterpiece].
In some of these books there are ideas concerning science that are false. That does not make them pseudo science. Mistakes made in good faith are not pseudo science.
Catholics have their own sets of books of ethics that are similar in purpose and for Christian people it is probably a good idea to learn them.
In no case does familiarity with these books give one a right to attack evolution or any legitimate science.
Also there is no place in any of these book where the idea of sitting and learning while others support one is defended.
