In 1078, Saint Anselm of Canterbury proposed a proof of God’s existence in his work Proslogion, which has given rise to various versions that attempted to improve it (usually without success) and to attempts to demolish it. Even today, it continues to provoke the attention of philosophers and corrections to its translation. This is Saint Anselm's argument, originally written in Latin, as it is usually translated:
i.
That than which nothing greater can be conceived at any rate
exists in the mind of the fool who says there is no such thing.
ii.
If that than which nothing greater can be conceived is only in a
mind, it can be thought to exist in reality too, which is greater.
iii. Therefore
if that than which nothing greater can be conceived is only in a mind, it is
not that than which nothing greater can be conceived.
iv. But it is a
contradiction to say that something than which nothing greater can be conceived
is something than which a greater can be conceived.
v. Therefore that than which nothing greater can be conceived exists in reality as well as in the mind.
