👉 In classical Greek philosophy, "Tholus" is a word that refers to an object or concept without having any direct relationship with other objects. It can be used in various contexts, such as metaphysics and epistemology, where it signifies an abstract idea or concept without concrete reference points. The term "Tholus" was introduced by Aristotle in his work "De Rerum Natura et Commentarii Animalium", which is considered one of the most important works on philosophy.
