Prof. Lottenbach PREPARES for lectures (I see him in his office, through the hazy glass, pacing/practicing). He is extremely competent, thorough, and engaging. He simply knows his stuff. He offers historical background to the ideas he introduces without making it a survey course. He's enthusiastic after class hours also. Just make sure you're interested in the answer, because the man will talk and talk. I certainly hope he stays at UCLA a bit longer. UCLA can definitely use someone with his phisosophical background. Simply stated, he teaches philosophy well.
