In conclusion, Locke's philosophy is very good because he wants all people to know the facts by using experience through sensations. As we have known, something around us is abstract therefore we need to find the truth and reality. As Locke has mentioned above education is very important for all people. So, not only people in other countries but also people in Cambodia parents have to send their children to study at schools. It is a good reason that children are easy to acquire knowledge when they are children because in this stage John Locke held that at birth the human mind is a blank slate, empty ideas. In contrast, if parents don not send them to study it means that their children will be poor at knowledge. At last, Locke said that the goal of education is the welfare and prosperity of the nation- Locke conceived the nation's welfare and prosperity in terms of the personal happiness and social usefulness of its citizens.
