Final answer:
John Locke and David Hume both advocated for empiricism, the idea that humans learn concepts through experience, with our senses playing a key role in forming our knowledge.
Step-by-step explanation:
John Locke and David Hume shared similar views on how humans learn concepts, subscribing to the theory of empiricism. According to Locke's work in An Essay Concerning Human Understanding, he believed that at birth, our minds are blank slates, or tabula rasa, and that all human knowledge comes from sensory experiences which then form simple ideas that lead to complex ones. Hume, though skeptical about the certainty of knowledge, agreed that knowledge comes via the senses but doubted our reasoning could lead to incontrovertible truths. Both rejected the idea of innate knowledge, positing instead that knowledge is based on experience and subject to continual revision.
