In his lengthy and intense philosophical career, Castaneda deeply influenced analytic philosophy. In the last part of his life, he was also committed to spreading his views beyond the circle of analytic philosophy and to bridging the gap between analytic and so-called continen tal philosophy, convinced as he was of the overall unity of good philosophical theoriz ing. The importance and influence of his work is witnessed by three Festschriften ded icated to him, which included critical examinations of his theories by leading philoso phers, along with Castaneda's replies (Tomberlin 1983, 1986; Jacobi & Pape 1980). Castaneda's humanity and devotion to philosophy is evidenced in his fascinating autobiography, contained in Tomberlin 1986. He was also the founding editor of Nous, one of the world's best philosophical journals, now published by Blackwell Publishers. From the beginning, Nous emphasized the analytic tradition in philosophy, but has al ways been open to all kinds of serious philosophy, as its Latin motto witnessed: Nihil philosophicum a nobis alienum putamus.
