The concept of the struggle for existence refers to the rivalry for resources essential to survival, a principle observed in both nature and human societies. Originating in ancient philosophy and later formalized by thinkers such as Malthus and Darwin, it became a central element of evolutionary theory, explaining natural selection through competition.
Authors like Alfred Russel Wallace highlighted its role in encouraging human creativity, while Thomas Huxley connected it to societal assertiveness. L.H. Bailey challenged more severe interpretations, arguing that the struggle is inherently just, promoting life's continuation through ability. Although debated, the idea remains a fundamental aspect of biological and social thought, evolving from a harsh mechanism of survival to a more refined force influencing adaptation and collaboration.
