A second line of thought also supports an equality of opportunity conception of distributive justice. This line of thought is discernible in chapter two of John Rawls's classic treatise on justice (Rawls 1999; see also Barry 1989: chapter 6). If we accept that people ought to enjoy formal equality of opportunity or careers open to talents, we should be concerned that morally arbitrary good and bad fortune can determine whether individuals have the opportunity to develop their potential talents and become qualified for positions that confer special advantages and favorable life prospects. If we accept that this morally arbitrary good and bad fortune should not determine people's prospects, we are led to accept FEO. This substantive equal opportunity doctrine is satisfied when all those with the same native talent and the same ambition have the same prospects of competitive success.
