Justice as utility
Or actually vice versa, utility applied properly in the society turns out, boils down to justice. Justice, in its turn, takes a wide variety of disguises, from the lex talionis, as we are taught the name of the old principle: an eye for an eye and a tooth for a tooth to the various notions of justful taxation. The former has been abandoned in the present Western societies, and the latter continuously debated. Generally accepted is the principle of progressive taxation, which is mild for small earnings and severe for big. But equally it is accepted as justice and seen utilitarian that talent and diligency are remunerated more than lazyness and ineffectiveness.
But could it not be so that all earnings give the same proportion to government for justful redistribution and let the market of supply and demand determine the justful earnings. Or could'nt the taxation be completely separated from personal earnings and paid from revenue of product entering the market? This notion of faceless taxation I have not seen anywhere else, so may consider my own utopian contribution to the idea of justful taxation.
And what is the utility itself? The utilitarian doctrine is, that happiness is desirable, and the only thing desirable, as an end; all other things being only desirable as means to that end. Happiness is not an abstract idea, but a concrete whole; and these are some of its parts. But if this doctrine be true, the principle of utility is proved.
