Last night, on the 2nd anniversary of the atrocities of October 7th, 2023, @bariweiss and I tried to make sense of what happened, and why so much of the world's reaction was quite different from our own. @TheFP

It does matter, Matt. Human reasoning cannot be fully developed without the skills of reading and remembering texts, thinking for oneself, writing down ideas, and engaging in written and spoken debates. We are in the midst of a disastrous educational collapse, which AI will only sped up.

Vince Ebert@VinceEbert·
Wir leben in einer Kultur der Überempfindlichkeit und Wehleidigkeit, in der es darum geht, einen möglichst prominenten Opferstatus zu erlangen. Weil das aber nicht argumentativ sondern nur emotional möglich ist, müssen fast zwangsläufig Fakten durch Gefühle ersetzt werden. Und Gefühle durch Argumente.  So werden an Universitäten „Safe Spaces“ eingerichtet, die die Studenten vor neuen Erfahrungen, Ideen und Widerspruch schützen sollen. Die jungen Menschen lernen sozusagen, wie man sich hilflos fühlt. Nicht selten kippt diese erlernte Hilflosigkeit in Wut um. So hat sich in unserer Gesellschaft Stück für Stück eine Tyrannei der Wehleidigen etabliert, die ihre Aggressivität als Notwehr verkaufen, um ihren Willen durchzusetzen.

@SuayibUestuen Really, Suyaib? Did you ever teach large classes? What you do is downplaying those who have to deal with large BSC classes. Thanks

Good for you! Teaching a small group of motivated students is certainly rewarding, and you're fortunate not to have to handle the basics with 300 students. However, that foundational work is essential for attracting those motivated students to your course in the first place.
Şuayb Üstün 🌱👨🏻‍🔬@SuayibUestuen

Some profs. downplay course teaching: Over 5 weeks,we gave 10+lectures (30-60 min),worked 8-20+ hrs (incl. weekends) preparing, organized a student seminar with paper presentations,held an exam, & found interactions more rewarding than lecturing to 300 students #AcademicChatter

Der Chinesische Garten braucht dringend Spenden. Verwitterungsschäden und vor allem jahrelanger Vandalismus haben ihm schwer zugesetzt. Bitte helfen Sie, dieses Juwel im Botanischen Garten der #ruhrunibochum zu erhalten! gofund.me/686f25a9
