Final answer:
The philosopher who believed knowledge comes from memories is Plato. He suggested that knowledge is remembering ideal forms known to our souls prior to birth.
Step-by-step explanation:
The Greek philosopher who argued that all knowledge comes from experience stored in memories is Plato. Unlike his teacher, Socrates, who derived principles from ethical conduct and essential truths, Plato derived principles from careful recollection. Plato's theory of forms suggests that knowledge is the act of remembering the pure, ideal forms of things that our souls were in contact with before being born into the world. This concept of recollection and the existence of a realm of eternal forms were central to how Plato explained knowledge and understanding.
