An Essay Concerning Human Understanding

Key themes and ideas explored in An Essay Concerning Human Understanding include: Empiricism: Locke is often regarded as one of the primary proponents of empiricism a philosophical stance that emphasizes the role of experience and sensory perception as the sources of human knowledge. He argues that all human ideas and knowledge are ultimately derived from experience. Tabula Rasa: Locke introduces the concept of tabula rasa which translates to blank slate in Latin. According to this notion the human mind is born as a blank slate devoid of innate ideas or preconceived knowledge. Knowledge is then acquired through sensory experience and reflection on those experiences. Primary and Secondary Qualities: Locke distinguishes between primary qualities (such as size shape and motion) and secondary qualities (such as color taste and sound). Primary qualities exist in the external world and are inseparable from the objects themselves while secondary qualities are dependent on the perception of the observer.

He explores how we form the idea of substance which refers to the underlying reality that supports the qualities of objects. Additionally Locke discusses the continuity of personal identity over time and the criteria for the persistence of the self.
