Abstract

In modern European culture the explication and the understanding of nature is determined by the specific traits of systemic objects investigated by science. The paper singles out three types of systemic objects, i.e. simple (mechanical) objects, complex self-regulating, and complex self-developing systems. Categorical structures accounting for each of these types are analyzed.The paper shows that the investigation of every new type of systems changes the type of scientific rationality (classical, nonclassical, post-nonclassical)
