This paper starts with an analysis of the maker’s knowledge principle as one of the main characteristics of Modern epistemology. We start by showing that maker’s knowledge can be understood in two ways: 1) a negative sense, as a way of establishing limits to human knowledge: we can only know what we create; and 2) a positive sense, as legitimizing human knowledge: we effectively know what we create. We proceed then to examine the roots of the maker’s knowledge principle in (...) the context of the transition from Greek philosophy to early Christian thought, seeing Philo of Alexandria as perhaps the first to formulate an early version of the principle. We conclude that it is the Christian conception of God as creator that makes possible a redefinition of the relation between knowing and creating, opening the way to the Modern formulation of the principle.
