According to Locke, what do humans lack at birth according to the tabula rasa concept?

The tabula rasa concept, which means "blank slate," posits that individuals are born without built-in mental content. According to John Locke, this implies that humans lack knowledge at birth. He argued that the mind starts as a blank slate, and as individuals experience the world and interact with their surroundings, they accumulate knowledge through sensory experiences and reflection. This understanding contrasts with the notion of innate ideas, where knowledge is thought to be inherent rather than acquired through experience. Therefore, the emphasis on the absence of knowledge aligns directly with Locke’s view on human development and the acquisition of understanding over time through interaction with the environment.
