Abstract
‘Prejudice apart, the game of push-pin is of equal value with the arts and sciences of music and poetry’, was penned by Jeremy Bentham in 1825, but could as appropriately appear in most contemporary treatments of social choice and rationality. Political economists still use the felicific calculus; they search for ‘the greatest happiness of the greatest number’ by exploring means and consequences of aggregating individuals' preferences to form social choices among competing values. The values are assigned equal weight. The origins and processes of development of individual preferences are taken as ‘givens’, i.e. as irrelevant to the problem of social choice. What counts is rational behaviour, which is said to exist when action is ‘correctly’ designed to maximize goal achievement, ‘given the goal in question and the real world as it exists’.
