Why Is There Anything At

Our Reasonings Are Grounded Upon Two Great Principles, That Of Contradiction, In Virtue Of Which We Judge False That Which Involves A Contradiction, And True That Which Is Opposed Or Contradictory To The False.

There Are Also Two Kinds Of Truths: Truth Of Reasoning And Truths Of Fact.

Let There Be Two Possible Things, A And B, One Of Which Is Such That It Is Necessary That It Exists, And Let Us Assume That There Is More Perfection In A Than In B. Then, At Least, We Can Explain Why A Should Exist Rather Than B And Can Foresee Which Of Them Will Exist; Indeed, This Can Be Demonstrated, That Is, Rendered Certain From The Nature Of The Thing.

But In Simple Substances The Influence Of One Monad Over Another Is Ideal Only.

The Present Is Great With The Future.
