No One Really Knew The Sciences Except

First, By The Figurations Of Art There Be Made Instruments Of Navigation Without Men To Row Them, As Great Ships To Brooke The Sea, Only With One Man To Steer Them, And They Shall Sail Far More Swiftly Than If They Were Full Of Men; Also Chariots That Shall Move With Unspeakable Force Without Any Living Creature To Stir Them. Likewise An Instrument May Be Made To Fly Withall If One Sits In The Midst Of The Instrument, And Do Turn An Engine, By Which The Wings, Being Artificially Composed, May Beat The Air After The Manner Of A Flying Bird.

But We Must Here State That We Should Not See Anything If There Were A Vacuum. But This Would Not Be Due To Some Nature Hindering Species, And Resisting It, But Because Of The Lack Of A Nature Suitable For The Multiplication Of Species; For Species Is A Natural Thing, And Therefore Needs A Natural Medium; But In A Vacuum Nature Does Not Exist.

Experimental Science Is The Queen Of Knowledge.

There Are Four Chief Obstacles In Grasping Truth ... Namely, Submission To Faulty And Unworthy Authority, Influence Of Custom, Popular Prejudice, And The Concealment Of Our Own Ignorance Accompanied By An Ostentatious Display Of Our Knowledge.

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.'
