From each according to his ability, to each according to his needs (; ) is a slogan first used by Louis Blanc in 1851 (although an earlier version of the saying appeared in Étienne-Gabriel Morelly's The Code of Nature) and popularised by Karl Marx in his 1875 Critique of the Gotha Program. The principle refers to free access and distribution of goods and services. In the Marxist view, such an arrangement will be made possible by the abundance of goods and services that a developed communist system will produce; the idea is that, with the full development of socialism and unfettered productive forces, there will be enough to satisfy everyone's needs.
