This being exists so truly that it cannot be thought not to exist. For it is possible to think that something exists that cannot be thought not to exist, and such a being is greater than one that can be thought not to exist. Therefore, if that then which a greater cannot be thought can be thought not to exist, then that than which a greater cannot be thought is not that than which a greater cannot be thought; and this is a contradiction. So that than which a greater cannot be thought exists so truly that it cannot be thought not to exist.
I took intro to political thought instead of philosophy, much more concrete.
Traditionally, logic is studied as a branch of philosophy...Since the mid-nineteenth century formal logic has been studied as the foundation of mathematics. In 1903 Bertrand Russell and Alfred North Whitehead established logic as the cornerstone of mathematics with the publication of Principia Mathematica.
Ugh, why did I take Philosophy
there is nothing concrete about "I think, therefore I am".
