Knut D. Peterson (When Alaska Was Free, 1977) talks about "odd balls": "His true nature, whether he knows it or not, is to search for the unknown. He doesn’t look down on anybody, regardless of caste, race or color. Neither does he look up to anyone, no matter how high he may have climbed. He is a sort of loner, although he is not necessarily lonesome. The herd instinct doesn’t apply to his nature. Above all, he is a free agent."
