I Hold That It Is Only When

The Present Is Great With The Future.

I Am Convinced That The Unwritten Knowledge Scattered Among Men Of Different Callings Surpasses In Quantity And In Importance Anything We Find In Books, And That The Greater Part Of Our Wealth Has Yet To Be Recorded.

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

Now, As There Is An Infinity Of Possible Universes In The Ideas Of God, And As Only One Of Them Can Exist, There Must Be A Sufficient Reason For God's Choice, Which Determines Him Toward One Rather Than Another. And This Reason Can Be Found Only In The Fitness, Or The Degrees Of Perfection, That These Worlds Contain, Since Each Possible Thing Has The Right To Claim Existence In Proportion To The Perfection It Involves.

The Monad, Of Which We Shall Speak Here, Is Nothing But A Simple Substance Which Enters Into Compounds; Simple, That Is To Say, Without Parts.
