At present, all existing so-called theories of justice, except only for utilitarianism, divide the history of humanity into long years of hopeless night and a few minutes of long-awaited dawn. Any theory must be disregarded if it assumes that for centuries people have come to terms with their lack of freedom only because of mental limitations or an unusual strictness of the ruling elite. Therefore any theories that are not able to explain historical changes to people's perceptions of justice must undoubtedly be deemed unrealistic and incorrect. Utilitarianism does not have this disadvantage, but it does have another well-known defect which has to do with the use of the strange and immeasurable concept of utility. In my opinion, to this day there have never been any significant barriers preventing the use of personal profit as the primary motive for human behaviour. This will not only restore the position of utilitarianism so undeservedly lost, but also provide an opportunity to solve a number of theoretical issues and will also fill with optimism the conclusions that follow from Arrow's Impossibility Theorem.
