The following article aims to consider the problem of the empirical consummation of the teleological programme of practical reason in Kant. In other words, it highlights the question about the possibility of achieving the final end in the world. Nature is the domain of mechanical causality, but also of free causality and the highest good. Specifically, I will focus on the field of Kantian philosophy of history, examining it with regard to the possibility of biological evolution and the possibility of moral evolution of humankind.
