Epistemology is the branch of philosophy that deals with the theory of knowledge. Its standard questions (e.g., what is knowledge? how does knowledge differ from true belief?) are normative and non-empirical. Developmental epistemology (i.e., Piaget‘s genetic epistemology) deals with the genesis or development of knowledge in two respects: 1. its initial formation and 2. its valid constitution.
