Study presents Hayek's reflection of evolutionary theory and its incorporation to his philosophy. The structure is as follows: (i) Evolutionary theory is a constitutive part of Hayek's work and it is impossible to fully understand his philosophy without its reflection.
This approach is also fundamental for historical and systematic classification of his philosophy; (ii) Evolutionary theory can be described as a hypothetical tool for explaining some phenomenon, although not only for those in biological realm. This inspires and defines Hayek's position in methodology of science and his concept of "explanation of principle"; (iii) Aim of evolutionary theory is to explain an emergence of spontaneous orders.
Among them Hayek counts society and mind as those most complex. By adapting many philosophical characteristics of evolutionary theory (like problem of teleology, chance, relation between empirical based knowledge and explanation of principle or philosophy of history) Hayek offers perspective for interpretation of his concepts and themes.
Those features constitutes a bridge between micro and macro perspective, therefore explain origin of our cognitive structures as well as evolution of societies and institutions.
