Abstract: Charles Percy Snow first talked of two cultures in a Rede Lecture he delivered in Cambridge 50 years ago (Snow in The two cultures and the scientific revolution, Cambridge University Press, Cambridge, 1959). In the lecture he had only spoken of scientific and literary cultures, but the concept has gradually become extended beyond the literary culture, to encompass the broader world of arts. Thus, the expression is now routinely used to define the scientific and the artistic cultures. Which have important intrinsic differences: the scientific culture is objective and generates products that require verification [The term verification is used here in a general sense. It would perhaps be more appropriate to use the term falsification. In Popper’s (The Logic of Scientific Discovery, Basic Books, New York, 1959; Conjectures and Refutations, Rutledge, London, 1963) lexicon, a theory or, more generally, an assertion, is only scientific if it is falsifiable: which, however, does not mean that it is false]. The artistic culture is subjective, and, as a rule, does not demand verification. Science progresses, art changes, but the notion of progress is alien to it. These undisputable differences have been frequently underlined, however, the two cultures also have important points of contact. This contribution will discuss the most important, i.e., the commonality of their general aims, and the structure of the creativity process.
