There Are Two Famous Labyrinths Where Our Reason Very Often Goes Astray. One Concerns The Great Question Of The Free And The Necessary, Above All In The Production And The Origin Of Evil.

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.

Thus Men Are Linked With The Animals, These With The Plants And These With The Fossils Which In Turn Merge With Those Bodies Which Our Senses And Our Imagination Represent To Us As Absolutely Inanimate.
