There Are In Fact Four Very Significant

The Strongest Arguments Prove Nothing So Long As The Conclusions Are Not Verified By Experience. Experimental Science Is The Queen Of Sciences And The Goal Of All Speculation.

For The Things Of This World Cannot Be Made Known Without A Knowledge Of Mathematics.

No One Really Knew The Sciences Except The Lord Robert, Bishop Of Lincoln, By Reason Of His Length Of Life And Experience, As Well As Of His Studiousness And Zeal. He Knew Mathematics And Perspective, And There Was Nothing Which He Was Unable To Know; And At The Same Time He Was Sufficiently Acquainted With Languages To Be Able To Understand The Saints And The Philosophers And The Wise Men Of Antiquity But His Knowledge Of Languages Was Not Such As To Enable Him To Effect Translations Until The Latter Portion Of His Life.

As Regards Authority I So Proceed. Boetius Says In The Second Prologue To His Arithmetic, 'if An Inquirer Lacks The Four Parts Of Mathematics, He Has Very Little Ability To Discover Truth.' And Again, 'without This Theory No One Can Have A Correct Insight Into Truth.' And He Says Also, 'i Warn The Man Who Spurns These Paths Of Knowledge That He Cannot Philosophize Correctly.' And Again, 'it Is Clear That Whosoever Passes These By, Has Lost The Knowledge Of All Learning.'

There Are Four Great Sciences, Without Which The Other Sciences Cannot Be Known Nor A Knowledge Of Things Secured ... Of These Sciences The Gate And Key Is Mathematics ... He Who Is Ignorant Of This [mathematics] Cannot Know The Other Sciences Nor The Affairs Of This World.
