Sublime is the quality of greatness or vast magnitude, whether physical, moral, intellectual, metaphysical, aesthetic, spiritual or artistic.
Kant (1764)- He distinguishes between the “remarkable differences” of the Beautiful and the Sublime, noting that beauty “is connected with the form of the object”, having “boundaries”, while the sublime “is to be found in a formless object”, represented by a “boundlessness”
