John Locke wtore two essays on hyman development, Essay Concerning Human Understanding and Some Thoughts Concerning Education. In Essay Cooncerning Human Understanding John Locke explains how humans grasp material lthat is brought before them. He says that when a person is born their mind is blank, and the mind gains knowledge from contact with the world. In his view external material things are objects of sensation, and the operations of our own minds within are the objects of reflection. He is saying that experience with the world and society gives you ideas because you see material things and your mind is constaly reflecting on these ideas. When that keeps happening you get a certain knowledge of the things you see. He also belived that productivity an intelligence will come if you are provided with the proper enviroment and education. In his other essay Some Thoughts Concerning Education he explains ways to educate children. He says that the human mind is more tender when it is young so you should teach them when they are young. You should be mild but firm in teaching kids, young minds should be made obedient to discipline and pliant to reason. He makes it clear that you should not curb the young mind to much because it would be in worse shape then before. Rewards and punishments should keep kids in order he says. That is what John Locke thought about education and knowledge.
