Pure Earth Does Not Petrify, Because The Predominance Of Dryness Over [i.e. In] The Earth Endows It Not With Coherence But Rather With Crumbliness. In General, Stone Is Formed In Two Ways Only (a) Through The Hardening Of Clay, And (b) By The Congelation [of Waters].

Medicine Is The Science By Which We Learn The Various States Of The Human Body In Health And When Not In Health, And The Means By Which Health Is Likely To Be Lost And, When Lost, Is Likely To Be Restored Back To Health. In Other Words, It Is The Art Whereby Health Is Conserved And The Art Whereby It Is Restored After Being Lost. While Some Divide Medicine Into A Theoretical And A Practical [applied] Science, Others May Assume That It Is Only Theoretical Because They See It As A Pure Science. But, In Truth, Every Science Has Both A Theoretical And A Practical Side.

Now It Is Established In The Sciences That No Knowledge Is Acquired Save Through The Study Of Its Causes And Beginnings, If It Has Had Causes And Beginnings; Nor Completed Except By Knowledge Of Its Accidents And Accompanying Essentials.

An Ignorant Doctor Is The Aide-de-camp Of Death.

Medicine Considers The Human Body As To The Means By Which It Is Cured And By Which It Is Driven Away From Health.
