Generosity is the act of giving away what is ours without any expectation of return. While some philosophers argue it is against our biological nature to sacrifice anything without receiving an equivalent personal benefit, many others insist it is actually one of the essential traits that allowed humans to evolve into the complex, relational, community-based creatures that we are. While we often focus our concept of generosity around money, it actually encompasses anything that we perceive to be ours, including time and energy. Those who cultivate generosity often cite both personal good feelings and the increased well-being of those around them as their motivations. While it is hard to truly measure the outcome of any one act of generosity, most ripple outward in tangible and intangible ways, providing increased levels of security, encouragement, freedom, dignity, joy, and support throughout our communities.
