Locke attacks both the view that we have any innate principles (for example, the whole is greater than the part, do unto others as you would have done unto you, etc.) as well as the view that there are any innate singular ideas (for example, God, identity, substance, and so forth). The main thrust of Locke’s argument lies in pointing out that none of the mental content alleged to be innate is universally shared by all humans. He notes that children and the mentally disabled, for example, do not have in their minds an allegedly innate complex thought like “equals taken from equals leave equals”. He also uses evidence from travel literature to point out that many non-Europeans deny what were taken to be innate moral maxims and that some groups even lack the idea of a God. Locke takes the fact that not all humans have these ideas as evidence that they were not implanted by God in humans minds, and that they are therefore acquired rather than innate.
The strength and well being of a society is largely determined by the capacity of its members to work cooperatively together towards common goals (a common good). The most significant disruption of this strength is related to the integrity of human character with regard to how we relate to and work with one another. Socrates spent most of his life in the context of Athenian democracy. In Socrates' Athens, the role of the citizen was much more central to the functioning of Athenian democracy than it is in the democratic republic of the .. Male citizens were required to participate in their government through mandatory military service and through their participation (randomly chosen) on the council. The ability of all citizens to relate to one another with integrity was of the utmost importance because acquiring a high position in the government was possible for any male citizen who was at least 30 years old. When Socrates asked questions such as "What is justice?" or "What is virtue?", he was not interested in academic abstractions. Socrates' goal was to learn what it meant to live as a just and virtuous citizen. This was of the utmost importance to Socrates because he knew that the good character of individuals contributed directly to the survival and well being of his whole society. When the learning and thinking habits of the people become slack, that is, when the masses do not live examined lives, democracy becomes a fast road to tyranny. When the justice and skillful virtue of the human character of individual citizens is harmed, society is harmed. This reality underlays Socrates' comment in Plato's Republic (564a) that, "tyranny is probably established out of no other regime than democracy...the greatest and most savage slavery out of the extreme of freedom."
