Not dumb at all. Perhaps the context of your enquiry makes it especially interesting.
>From Critique of the Gotha Programme, written spring 1875 but not published
till 1891.
Part I commenting on the third sentence taken from the original programme.
Firstly describing "the lower phase" of communism:-
" The right of the producers is proportional to the labor they supply; the equality consists in the fact that measurement is made with an equal standard, labor.
But one man is superior to another physically, or mentally, and supplies more labor in the same time, or can labor for a longer time; and labor, to serve as a measure, must be defined by its duration or intensity, otherwise it ceases to be a standard of measurement. This equal right is an unequal right for unequal labor. ....
But these defects are inevitable in the first phase of communist society as it is when it has just emerged after prolonged birth pangs from capitalist society. Right can never be higher than the economic structure of society and its cultural development conditioned thereby.
In a higher phase of communist society, after the enslaving subordination of the individual to the division of labor, and therewith also the antithesis between mental and physical labor, has vanished; after labor has become not only a means of life but life's prime want; after the productive forces have also increased with the all-around development of the individual, and all the springs of co-operative wealth flow more abundantly -- only then then can the narrow horizon of bourgeois right be crossed in its entirety and society inscribe on its banners: From each according to his ability, to each according to his needs!
