It Is Necessary To Believe That The Mixture Of Evil Has Produced The Greatest Possible Good: Otherwise The Evil Would Not Have Been Permitted.

These Principles Have Given Me A Way Of Explaining Naturally The Union Or Rather The Mutual Agreement [conformité] Of The Soul And The Organic Body. The Soul Follows Its Own Laws, And The Body Likewise Follows Its Own Laws; And They Agree With Each Other In Virtue Of The Pre-established Harmony Between All Substances, Since They Are All Representations Of One And The Same Universe.

Take What You Need, Do What You Should, You Will Get What You Want.

I Agree With You That It Is Important To Examine Our Presuppositions, Throughly And Once For All, In Order To Establish Something Solid. For I Hold That It Is Only When We Can Prove All That We Bring Forward That We Perfectly Understand The Thing Under Consideration. I Know That The Common Herd Takes Little Pleasure In These Researches, But I Know Also That The Common Herd Take Little Pains Thoroughly To Understand Things.

For, Above All, I Hold A Notion Of Possibility And Necessity According To Which There Are Some Things That Are Possible, But Yet Not Necessary, And Which Do Not Really Exist. From This It Follows That A Reason That Always Forces A Free Mind To Choose One Thing Over Another (whether That Reason Derives From The Perfection Of A Thing, As It Does In God, Or From Our Imperfection) Does Not Eliminate Our Freedom.
