As one examines the research by Alan Turing, one realizes a discrepancy between his early and late works. At the beginning of his career, his sole focus was mathematical logic, computability of numbers, mechanistic description of mathematical operations, and so on. However, in his late research, one of the most fascinating articles on biology and chemistry is found -his examination of the chemical basis of morphogenesis. The question is how his research on morphogenesis relates to his earlier research. In this article, it is argued that Turing's desire to develop 'artificial cognition' and the cybernetics-friendly atmosphere of the late 1940s are the links connecting his two research periods.
