Altruism is the act of doing something for someone else's benefit, with no benefit for the person conducting the act, popularly known as being 'unselfish'. <a href="https://alelici.wordpress.com/2016/05/09/sustainability-assessmentsaloka-ultrasound-transducer/>Aloka Ultrasound Transducer</a>The term was first employed by the French philosopher Comte, to signify devotion to others or to humanity; the opposite of selfishness or egoism. Some argue that true altruism must be an act that not only benefits another person, but does so to the detriment of the person conducting the altruistic act. This self-sacrifice is of coursecontrary to the basic principles of survival, and as such many psychologists argue that no human act is ever truly altruistic, but is indeed self-serving. A typical example cited is a parent risking their life to save their child. In this example the parent is actually serving their basicinstinct to protect the genes which they have passed on and are being carried by the child.<a href="http://alelici.webs.com/>Defibrillator battery</a> Similarly, an adult risking their life to save a stranger, it is argued, follows the same pattern. The humanrace developed from a small family and as such we all share some genes, the stranger is part of our family, albeit remotely, and we are simply acting - unconsciously - to save our own genes.<a href="http://alelici.yolasite.com/>Jaundice Meter battery</a> Other apparently altruistic acts, such as being kind to someone, it is argued are done with a view to some future payback. The stranger may help us in the future, or may help someone else who helps someone until the kindness goes full circle and someone is kind to us. An act which hopes for a benefit for the perpetrator of the act, such as a future kindness being received, or securing a place in a holy after-life, is not altruistic, but selfish, no matter how kind it may be.
