Good manifests good – we cause good to be and to happen. Technically, Jonathan Haidt described it as elevation, which is an emotion elicited by witnessing virtuous acts of remarkable moral goodness. It is experienced as a distinct feeling of warmth and expansion that is accompanied by appreciation and affection for the individual whose exceptional conduct is being observed. Elevation motivates those who experience it to open up to, affiliate with, and assist others. Elevation makes an individual feel lifted up and optimistic about humanity.
