All right, Schwartz, tackle my mind now. Go as deep as you want. I was born on Baronn in the Sirius Sector. I lived my life in an atmosphere of anti- Terrestrialism in the formative years, so I can't help what flaws and follies lie at the roots of my subconscious. But look on the surface and tell me if, in my adult years, I have not fought bigotry in myself. Not in others; that would be easy. But in myself, and as hard as I could. .Isaac Asimov
