Locke’s tabula Rosa states that a child is born with no knowledge whatsoever however, it has been argued that Knowledge arises from genetic information honed by a process of natural selection. Some portions of this knowledge might be nurtured, but genetically determined forms also may modify how we categorize our experiences.
Darwin said when child was born he/she don’t have experience but he/she has instinct to survive when he/she get older. He/she will gain experience and the experience will fine tune the survival skill and become knowledge when a child increases a longer memory, a keener imagination and became involved in social contracts. a child’s knowledge about certain things about the world are innate, although can be changed by interactions with family, education, religion and society. This knowledge is about object and what is valued is "natural" having been repeatedly experienced over time.
