The Critique is also notable for elucidating the principles of "To each according to his contribution" as the basis for a "lower phase" of communist society directly following the transition from capitalism, and "From each according to his ability, to each according to his needs" as the basis for a future "higher phase" of communist society. In describing the lower phase, he states that "the individual receives from society exactly what he gives to it" and advocates remuneration in the form of labour vouchers as opposed to money. The Critique of the Gotha Program, published after his death, was one of Marx's last major writings.
