Abstract
The purpose of this work is to explain the meaning of the biological terms "generatio aequivoca, Epigenesis, Praformation" in Kant's "Critique of Pure Reason", Chapter 27, within the historical context, and to show Kant's intentions by using them. Kant used these terms as biological analogies to illustrate the different epistemological positions of Locke, Leibniz and Hume (sensualism, rational dogmatism, scepticism) to form a contrast to his own point of view: "Epigenesis" stands for apodicticity, apriority, spontaneity and productivity of the categories of the intellect. This biological term allowed a dynamic imagination of knowledge as a product of pure intellect (form) and sensuality (matter). Kant defined the basic terms in his critique of the judgment (Chapter 81)
