PHIL165 . Holden T A 4 Months Ago

Professor Holden is a great philosophy professor. He's funny and tries to make the class as understandable as possible because Hume's works are pretty dense to get through. I didn't always go to lecture, but when I did, he made it easier to understand. Exams are reasonable and just essay questions. Do the readings and you'll do fine! He's great :)

PHIL20C . Holden T A 5 Months Ago

Holden is the GOAT. I had him for both PHIL20C and PHIL 167. His lectures are very interesting, you can tell he knows his stuff and he is passionate and thoughtful about the things he says. Even if you're not a philosophy major you'll likely enjoy 20C. Classes are graded on exclusively midterms and finals. If you do readings you'll do well.

PHIL20C . Holden T A 5 Months Ago

Prof Holden was okay. lectures were boring and there was tons of reading. no homework so the whole class was based on the final, midterm, and 2 papers. Papers aren't bad depending on your TA. the final was writing and wasn't too bad. I don't even like philosophy so I was so bored.

PHIL20C . Holden T A 1 Year, 10 Months Ago

Don't take this class as a GE. I'm a phil major, and even I had a hard time fully getting what Holden was saying sometimes. Graded on 2 papers, and a final. TA grading is harsh if you get a bad one. Lots of reading. If you can keep up, it's manageable. Prof is super passionate/funny, but sometimes unclear. Fine class, difficult for a lower div tho

PHIL20C . Holden T A 1 Year, 11 Months Ago

If you're not into PHIL- I wouldn't take this class. I think he is funny to PHIL majors, but I found his lectures bizarre. It's really hard to adjust to a PHIL class and learn how to write those papers if you are from basically any other major.
