Descartess PremiseDescartess Premise
Now it is manifest by the naturallight thatthere must at least be as much reality inthe efficient and total cause as in its effect.
For, pray, whence can the effect derive itsreality, if not from its cause? And in whatway can this cause communicate thisreality to it, unless it possessed it in itself?

And from this it follows, not only thatsomething cannot proceed from nothing,but likewise that what is more perfect --that is to say, which has more reality withinitself-- cannot proceed from the lessperfect.

Anselms ArgumentAnselms Argument
Even the Fool ... is forced to agree thatsomething, the greater than which cannot bethought, exists in the intellect, since he
understands this when he hears it, andwhatever is understood is in the intellect.

Anselms ArgumentAnselms Argument
And surely that, the greater than which cannotbe thought, cannot exist in the intellect alone.For if it exists solely in the intellect, it can be
thought to exist in reality, which is greater. If,then, that, the greater than which cannot bethought, exists in the intellect alone, this samebeing, than which a greater cannot be thought,is that than which a greater can be thought. Butsurely this is impossible.
