That that which is neither true nor truthlike does not exist. Now, whatever exists, exists otherwise in something else than it exists in itself.
Nicholas of CusaIf, therefore, man has come into the world to search for God and, if he has found Him, to adhere to Him and to find repose in adhering to Him-man cannot search for Him and attain Him in this sensible and corporeal world, since God is spirit rather than body, and cannot be attained in intellectual abstraction, since one is able to conceive nothing similar to God, as he asserts-how can one, therefore, search for Him in order to find Him?
Nicholas of CusaSince beings desire to exist, because to exist is a good thing: they desire the One without which they cannot exist.
