State any two ideas philosophers that you consider to be the most important for society to function effectively

Religious tolerance and liberty, as envisioned by Voltaire, are essential for a well-functioning society. Religious liberty protects religious minorities from oppression. It also promotes a kinder society in which people can freely practise their religion without fear of being judged. The writings of Jean Jacques Rousseau on the social contract are also significant. A sense of security is enhanced by a social contract between a government and its citizens. A government grants important rights to its citizens, such as the right to vote, under this agreement.
