EXCEPTION n. 4 definitions
from others; a person, thing, or case, specified as distinct, or not included; as, almost every general rule has its exceptions. Such rare exceptions, shining in the dark, Prove, rather than impeach, the just remark. Cowper.
EXISTENCE n. 3 definitions
Continued or repeated manifestation; occurrence, as of events of any kind; as, the existence of a calamity or of a state of war. The existence therefore, of a phenomenon, is but another word for its being perceived, or for the inferred possibility of perceiving it. J. S. Mill.
