In addition to spending many hours commenting on drafts of this dissertation, the two internal members of my dissertation committee, Professors Hannah Ginsborg and Daniel Warren, acted as my mentors throughout my time at Berkeley.

The two people who served as the outside members of my committee, Professors David Stern and Marianne Constable, also spent many hours reading and discussing my work with me.

My work has benefited from conversations with colleagues, former teachers, and new acquaintances. For their generous help, I am grateful to Henry Alison, Randall Amano, Karl Ameriks, Dorothy Brown, Quassim Cassam, David Cerbone, Willem deVries, Lorne Falkenstein, Eckart Förster, George Gale, Susan Hahn, Damian Konkoly, Alison Laywine, Rudolf Makkreel, Jeff Malpas, Lenny Moss, Wayne Martin, Bruce Merrill, Stephen Palmquist, Hoke Robinson, Fred Rush, Donald Rutherford, Gopal Sreenivasen, Jonathan Vogel, and Eric Watkins.

Jerry Robinson, David Lynaugh, Tim Ryan, and the rest of the exemplary administrative staff at the Berkeley Department of Philosophy have helped me more than they realize.

I owe a special debt to Ingrid Rieger, who taught me to read Kant's German.
