Thus we seem to be on the verge of an expansion of welfare economics into something like a social science of ethics and politics: what was intended to be a mere porch to ethics is either the whole house or nothing at all. In so laying down its life welfare economics may be able to contribute some of its insights and analytical methods to a much broader evaluative analysis of the whole social process.
Humans in modern societies are driven by a perhaps desperate hope that they might find some way of mobilizing their theoretical and empirical knowledge and their evaluative systems so as both to locate themselves and their projects in some larger imaginative structure that makes sense to them. ... Furthermore, many modern agents would like it to be the case that the form of orientation which their life has is, if not true, at least compatible with the best available knowledge.raymond geuss
Raymond Aron ascribes to Weber the view that ‘each man’s conscience is irrefutable.’ ... while [Weber] holds that an agent may be more or less rational in acting consistently with his values, the choice of any one particular evaluative stance or commitment can be no more rational than any other. All faiths and all evaluations are equally non-rational...alasdair macintyre
