A History and Philosophy of Science degree can be a bachelor's, master's, or doctorate degree. These programs often teach students the history of science from antiquity to the present, and the set of philosophical presuppositions that make up the sciences, which inform the different methodologies and implications of science. Students often may learn about how the scientific method was arrived at, and what its original formulators believed about the world. Students learn philosophical tenets such as metaphysics, logic, ontology, epistemology, history, and how these are relevant in historical and modern sciences.
