Happy People

The concept of personhood (who is a person within a society) is the fundamental component of any selective concept of people. A distinction is maintained in philosophy and law between the notions "human being", or "man", and "person". The former refers to the species, while the latter refers to a rational agent (for example, John Locke's Essay concerning Human Understanding II 27 and Immanuel Kant's Introduction to the Metaphysic of Morals). Central issues of interest to people are the understanding of the human condition and the meaning of life, and survival. Religion, philosophy, and science show or represent modes and aspects of inquiry which attempt to investigate and understand the nature, behavior, and purpose of people. Sociology, economics, and politics represent modes by which people investigate how to maximize a collective survival strategy.
In politics
Various republics govern, or claim to govern, in the name of the people. Both the Roman Republic and the Roman Empire used the Latin term Senatus Populusque Romanus, (the Senate and People of Rome). This term was fixed to Roman legionary standards, and even after the Roman Emperors achieved a state of total personal autarchy, they continued to wield their power in the name of the Senate and People of Rome. A People's Republic is typically a Marxist or socialist one-party state that claims to govern on behalf of the people. Populism is another umbrella term for various political tendencies that claim to represent the people, usually with an implication that they serve the common people instead of the elite.
