A hero (heroine is usually used for females) (Ancient Greek: ἥρως, hḗrōs), in Greek mythology and folklore, was originally a demigod, their cult being one of the most distinctive features of ancient Greek religion. Later, hero (male) and heroine (female) came to refer to characters who, in the face of danger and adversity or from a position of weakness, display courage and the will for self sacrifice—that is, heroism—for some greater good of all humanity. This definition originally referred to martial courage or excellence but extended to more general moral excellence.
Stories of heroism may serve as moral examples. In classical antiquity, hero cults that venerated deified heroes such as Heracles, Perseus, and Achilles played an important role in Ancient Greek religion. Politicians, ancient and modern, have employed hero worship for their own apotheosis (i.e., cult of personality).
Coined in English 1387, the word hero comes from the Greek "ἥρως" (heroes), "hero, warrior", literally "protector" or "defender" the postulated original forms of these words being *ἥρϝως, hērwōs, and *ἭρFα, Hērwā, respectively. It is also thought[citation needed] to be a cognate of the Latin verb servo (original meaning: to preserve whole) and of the Avestan verb haurvaiti (to keep vigil over), although the original Proto-Indoeuropean root is unclear.
War is an organized, armed, and often a prolonged conflict that is carried on between states, nations, or other parties typified by extreme aggression, social disruption, and usually high mortality. War should be understood as an actual, intentional and widespread armed conflict between political communities, and therefore is defined as a form of political violence. The set of techniques used by a group to carry out war is known as warfare. An absence of war (and other violence) is usually called peace.
In 2003, Nobel Laureate Richard E. Smalley identified war as the sixth (of ten) biggest problems facing the society of mankind for the next fifty years. In the 1832 treatise On War, Prussian military general and theoretician Carl von Clausewitz defined war as follows: "War is thus an act of force to compel our enemy to do our will."
While some scholars see warfare as an inescapable and integral aspect of human culture, others argue that it is only inevitable under certain socio-cultural or ecological circumstances. Some scholars argue that the practice of war is not linked to any single type of political organization or society. Rather, as discussed by John Keegan in his History of Warfare, war is a universal phenomenon whose form and scope is defined by the society that wages it. Another argument suggests that since there are human societies in which warfare does not exist, humans may not be naturally disposed for warfare, which emerges under particular circumstances. The ever changing technologies and potentials of war extend along a historical continuum. At the one end lies the endemic warfare of the Paleolithic[citation needed] with its stones and clubs, and the naturally limited loss of life associated with the use of such weapons. Found at the other end of this continuum is nuclear warfare, along with the recently developed possible outcome of its use, namely the potential risk of the complete extinction of the human species.
A police officer (also known as a policeman or policewoman, and constable in some forces, particularly in the United Kingdom and other Commonwealth nations) is a warranted employee of a police force. In the United States, "officer" is the formal name of the lowest police rank; in many other countries "officer" is a generic term not specifying a particular rank, and the lowest rank is often "constable". Police officers are generally charged with the apprehension of criminals and the prevention and detection of crime, and the maintenance of public order. Police officers may be sworn to an oath, and have the power to arrest people and detain them for a limited time, along with other duties and powers.
Some police officers may also be trained in special duties, such as counter-terrorism, surveillance, child protection, VIP protection, and investigation techniques into major crime, including fraud, rape, murder and drug trafficking.
Responsibilities of a police officer are varied, and may differ greatly from within one political context to another. Typical duties relate to keeping the peace, law enforcement, protection of people and property, and the investigation of crimes. Officers are expected to respond to a variety of situations that may arise while they are on duty. Rules and guidelines dictate how an officer should behave within the community, and in many contexts restrictions are placed on what the uniformed officer wears. In some countries, rules and procedures dictate that a police officer is obliged to intervene in a criminal incident, even if they are off-duty. Police officers in nearly all countries retain their lawful powers, while off duty.
