Some students, faculty members and administrators at UCLA were puzzled and dismayed by Kurt's teaching methods. His undergraduate art history lectures were wildly popular, and by 1966 upwards of 400 students were in attendance. He played rock and roll, brought in guest lecturers, and taught in a very unconventional style. In this lecture (drawn from word-for-word class notes) from December, 1966, he directly addressed criticisms he'd heard, and took pains to explain why he was teaching in the way he was: "This approach involves fundamental issues; it involves keeping open the live questions. This is very dangerous; it unsettles a lot of people; you keep the door open, you inevitably let the draft in...it gets very uneasy. You also inevitably let the light in, and that's another point."
