The wealth of exceptional Jewish-authored books which teach good behavior are taken from the good values found in the literature of psychology, which is not Torah nor nessesarily Jewish.

Bilaam Harasha said about the Jews
עם לבדד ישכון ובגוים לא יתחשב
That we are a self sufficient people!
We have our own values, holidays, music etc… Boruch Hashem we have a tremendous wealth today of the best educational books from acceptable and exceptional authors in our own Jewish bookstores and lending libraries that we don’t need any non jewish or irreligious books to infiltrate our kids’ pure minds with any improper subliminal messages of any sort.

For example, whereas both teach to love your fellow (yid?) as yourself, only one of them includes even the yid who sinned.

I can not understand where’s the good in today’s abundance of “refrum” literature. That kind of ahavas yisroel is not what the Baal Shem Tov taught. I therefore as a guide allow in only stories and lessons taught by the 9 Rebeiim, whose ahavas yisroel was deliberately extended to include balei avaira.

One exception (so far), and to the practical side, I have also purchased the Machanayim collection (softcover) even though the Sipuray Tzadikim extend beyond the Baal Shem Tov’s ahavas yisroel but that’s because we are all in need of quality replacements for the default Youtube videos which captivate our little ones. Machanayim is a highly recommended replacement for the likes of Dr Suess, among all the other Doctors’ Self-focused books found in your traifeh Readers Digest.

How do we know all Jewish authors are moral people? Do we assume they all are unless proven otherwise?

how do we know which non jewish authors might be moral people?

practically speaking, is there a list of non jewish books that are ok in content and with moral authors?
