The concept of “transition” (Danish Overgang, from Old Danish øwergong or owergong, Old Norse yfirgangr or yfirganga)1 is primarily used to designate processes of movement, roaming, change, becoming, or decay, that is, processes in which a substance passes from one state into another. Transitoriness is an essential hallmark not only of logical reality, but of historical and existential actuality as well. What unites logical, historical, and existential transitions is that the original state no longer obtains; another has taken its place.
