It Is Thus Necessary To Examine All

Galen , In The Third Section Of His Book, "the Use Of The Limbs," Says Correctly That It Would Be In Vain To Expect To See Living Beings Formed Of The Blood Of Menstruous Women And The Semen Virile, Who Will Not Die, Will Never Feel Pain, Or Will Move Perpetually, Or Shine Like The Sun. This Dictum Of Galen Is Part Of The Following More General Proposition: Whatever Is Formed Of Matter Receives The Most Perfect Form Possible In That Species Of Matter; In Each Individual Case The Defects Are In Accordance With That Individual Matter.

He Who Thinks He Can Have Flesh And Bones Without Being Subject To Any External Influence, Or Any Accidents Of Matter, Unconsciously Wishes To Reconcile Two Opposites, Viz., To Be At The Same Time Subject And Not Subject To Change. If Man Were Never Subject To Change There Could Be No Generation; There Would Be One Single Being, But No Individuals Forming A Species.

Be Convinced That, If Man Were Able To Reach The End Without Preparatory Studies, Such Studies Would Not Be Preparatory But Tiresome And Utterly Superfluous.

Inspire Me With Love For My Art And For Thy Creatures. In The Sufferer Let Me See Only The Human Being.

In The Realm Of Nature There Is Nothing Purposeless, Trivial, Or Unnecessary
