Okay, ancient enough, but fell into disuse around the Enlightenment, was hardly considered 100-120 years ago, returned among academic philosophers like Philippa Foot, Catholics like MacIntyre tryed to keep it alive, and it is only roughly about now that it is something slowly considered again by the hip young atheist literati classes for whom karma is merely a metaphor and do not literally believe in bad deeds putting a stain on the soul, so in this sense it is only a newly fashionable thing again.
