A enlightening post from some nutjobs who attack R’ Slifkin constantly sheds light on some of the mind-numbing and close-minded fanaticism rampant among haredim. It gives you a clear idea of what haredim think of secular knowledge. They hate non-frum books so much, is it any wonder that they abhor education and thus are mostly unemployed?
Yes, secular books are eminently capable of dragging a person off the path of emunah! The gemara in Chagiga (15b) relates that the great sage Elisha ben Avuya went off the derech because he was influenced by Greek culture (he was always whistling Greek tunes) and Greek attitudes (books of heresy)… Secular books are, for the most part, anti-Torah; they contain the attitudes of the gentile nations which are diametrically opposed to the attitude of the Torah. Even innocuous books, such as those on science, are tainted with the attitudes of the goyim. It is extremely dangerous for an innocent ben-Torah to start taking unwarranted and unsupervised excursions in the fields of gentile literature. Human beings, all human beings, are extremely impressionable and thus it is a sakana gedolah (great danger) to allow oneself to be exposed to foreign ideologies. This is the most obvious lesson that can be learned from this Ami article.
