●Natural rights - John Locke is well-known for claiming every human has certain rights not given to them by the law or society. Things such as freedom, privacy, life etc.Social ●Contract - Again Locke, but also prominent in Jean-Jaques Rousseau's writings. A political philosophy which claims that the government and people are bound under a contract, the government protects the people's natural rights and, in return, the people allow the government to rule.
●Revolution - If the government fails to protect the people's natural rights, Locke argued that it is essentially obligatory for the people to revolt.
●Reason - The ideas of the enlightenment are supported by reason, differing from previous eras which relied on supernatural and spiritual justifications.
