Final answer:
John Locke believed that humans learn subjects through their experiences and observations, and not through innate knowledge or concepts.
Step-by-step explanation:
John Locke believed that humans learn only from experience. He argued that at birth, our minds are blank slates or tabula rasa, and we gain knowledge through sensation and reflection. This means that Locke did not believe in innate knowledge or concepts. Instead, he believed that we learn subjects through our experiences and observations. For Locke, our minds aren't repositories of innate ideas; instead, they are shaped and enriched by the continuous influx of experiences, underscoring the profound influence of sensation and introspection in shaping human cognition and understanding.
