The most cited definition of awe is “an emotion in the upper reaches of pleasure and on the boundary of fear and that the stimulus is vast and that it requires accommodation” (Keltner & Hardt, 2003 p.297).
In 2023, Keltner defined awe as “the feeling of being in the presence of something vast that transcends your current understanding of the world”.
The origins of awe trace it back to the Old Norse and Icelandic words of agi, aghe, ege and aegilegur with meanings of terror or dread relating to mystical or divine beings. Fear is still associated with awe, though overall the valence of awe is classified as positive, aesthetic or self- transcendent.
