This book presents an extended argument for the thesis that people of the present day are not debarred in principle from passing moral judgement on people who lived in former days, notwithstanding the inevitable differences in social and cultural circumstances that separate us.  Some philosophers argue that because we can see things only from our own peculiar historical situation, we lack a sufficiently objective vantage point from which to appraise past people and their acts.  If they are correct, then the judgements passed by twenty-first-century people must inevitably be biased and irrelevant, grounded on moral standards that would have seemed alien in that 'foreign country' of the past.   This book challenges this relativistic position, contending that it seriously underestimates our ability to engage imaginatively with people who, however much their lifestyles may have differed from our own, were our fellow human beings, endowed with the same basic instincts, aversions, desires and aspirations.   Taking a stand on a naturalistic theory of human beings, coupled with a Kantian conception of the equal worth of all human members of the Kingdom of Ends, Scarre argues that historical moral judgements can be sensitive to circumstances, fitting and fair, and untainted by anachronism. The discussion ends by examining the implications of this position for the practice of historians and for the ethics of memory and commemoration.
