All Science Requires Mathematics.

One Man Alone Had Really Known The Sciences, Namely, Robert, Bishop Of Lincoln.

It Is Easier For A Man To Burn Down His Own House Than To Get Rid Of His Prejudices.

Mathematics Is The Gate And Key To Science.

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.
