There Are Also Two Kinds Of Truths:

In Symbols One Observes An Advantage In Discovery Which Is Greatest When They Express The Exact Nature Of A Thing Briefly And, As It Were, Picture It; Then Indeed The Labor Of Thought Is Wonderfully Diminished.

There Are Also Two Kinds Of Truths, Those Of Reasoning And Those Of Fact. Truths Of Reasoning Are Necessary And Their Opposite Is Impossible, And Those Of Fact Are Contingent And Their Opposite Is Possible. When A Truth Is Necessary Its Reason Can Be Found By Analysis, Resolving It Into More Simple Ideas And Truths Until We Reach Those Which Are Primitive.

Everything That Is Possible Demands To Exist.

What Is Is What Must Be.
