John Locke was a 17th-century English philosopher whose ideas greatly influenced the development of modern educational theory and practice. He is best known for his theory of empiricism, which emphasizes that knowledge comes from experience and sensory perception, and for advocating the idea that education should focus on developing a child's character and understanding rather than merely imparting knowledge. Lockeโs views on the mind as a blank slate (tabula rasa) shaped thoughts on child development and the purpose of education throughout history.
