Perhaps the strongest attempts to derive support for basic income policy from John Locke’s political philosophy hinge on Locke’s view that the world and its resources were originally owned in common by all persons. This world ownership, many have supposed, gives all persons a natural right to equal shares of resources and thus a right to an equal basic income under conditions (like our own) in which nearly all resources have been appropriated. This reasoning betrays a misunderstanding of Locke’s conception of original world ownership and, once this understanding is corrected, it becomes clear that there is no natural right to equal shares of resources, although there is a natural right to sufficient shares. Consequently, although governments must guarantee sufficiency for their citizens, there is no Lockean reason why this guarantee must take the form of a basic income or a scheme of equal and unconditional payments.
