The apikorsus and licentiousness on campuses today in 2010 is far greater than in 1930 to the point they aren’t even comparable. (Including the apikorsus at YU, such as the toeiva’niks gatherings, the bales of Apikorsus to be found in their library, ideas espoused even in the Limudei Kodesh courses that are against the Torah, never mind secular courses where clear anti-Torah ideas and ideals are taught by teachers who have all but carte blanche to say whatever they want, etc.) Rav Aharon Kotler ZT’L said many times that he will not enter YU because it is bad. His son, Rav Schneur ZT’L, followed suit.
Another point why attending modern universities ought give one deep pause if they value their Yiddishkeit and frumkeit and wish to keep it.
The Rama 246:4 rules explicitly that it is absolutely prohibited according to Halachah to engage in a curriculum of secular studies. To read secular studies now and then, is permitted, he says. The Birkas Shmuel (Kiddushin #27 p.42) and Kovetz Shiurim II:47 rules in accordance with this Rema.
Rav Elchonon Wasserman said that the confusion in Germany happened when people thought, mistakenly, that by Jews possessing secular knowledge the Goyim will hate them less. This caused a “negiyos” – a vested interest – that caused the German Jews to desire that their rabbis have a secular education as well.
Rav Moshe Feinstein ZT’L also denounced college in a Teshuva, and in a famous speech delivered to his students, published under the title “The Counsel of the Wicked” (Vaad LeHaromas Keren HaTorah, New York, 1978). There he reiterates that everyone has an obligation to become great in Torah, we should not care so much about Cadillac’s (yes, this was said in the “olden days”), and that learning Torah is what we should be pursuing, not secular stuff. He says in America you do not need college to make a Parnassa, and we should be willing to live on little, not a lot, for the sake of Torah, and that R. Nehuray’s statement of abandoning all skills in favor of Torah applies all that more today that we live in a country where you can make a parnassa without college, with no miracles needed.
The Chasam Sofer in Parsha Beshalach states clearly that certain secular knowledge is useful for learning certain Torah topics, such as cow anatomy being useful for shechitah, and arithmetic for Eruvin and Sukkah. But that before we embark on obtaining secular knowledge – and of course that means only to the extent that it is useful for our Torah studies – we must first fill ourselves with Torah-only knowledge. After we are strong in Torah, only then can we move to acquire the useful secular knowledge that we need for our Torah studies.
He quotes the Rambam, who he describes as “the father of philosophy” in our religion, in Hilchos Yesodei HaTorah, stating that a person may not learn philosophy until after he has “filled his stomach” with Shas and Poskim, which are the things, and only the things, that bring us Olam Habah. Then he quotes the Rashba, saying that there is a cherem against learning any secular studies if you are under age 25!
