ABSTRACT
This chapter describes the turbulent professional career and private biography of the most prominent anti-instinct scholar and researcher of the 20th century. It published in 1921, Zing-Yang Kuo assaulted the concept of instinct. It was during his senior year that Zing-Yang wrote his first critique of the instinct concept, which was published in the Journal of Philosophy in 1921. During 1928 and 1929, at his private research facility, away from the distractions of Shanghai, Zing-Yang began his first serious work on the development of behavior in mammalian fetuses and avian embryos. In addition, he became one of the few psychologists whose work was known to biologists-a rarer feat in those days than it is today. Except for a period in 1963, when he graciously consented to come to Raleigh, North Carolina, to help me begin my research on the duck embryo, Zing-Yang Kuo never again had the opportunity to work in a laboratory.
