Aidos (Greek: Αἰδώς, pronounced [ai̯dɔ̌ːs]) was the Greek goddess of shame, modesty, respect, and humility. Aidos, as a quality, was that feeling of reverence or shame which restrains men from wrong. It also encompassed the emotion that a rich person might feel in the presence of the impoverished, that their disparity of wealth, whether a matter of luck or merit, was ultimately undeserved. Ancient and Christian humility share common themes: they both reject egotism, self-centeredness, arrogance, and excessive pride; they also recognize human limitations. Aristotle defined it as a middle ground between vanity and cowardice.
