Who Would Dare Assert That We Know

The Deeper I Go In Considering The Vanities Of Popular Reasoning, The Lighter And More Foolish I Find Them. What Greater Stupidity Can Be Imagined Than That Of Calling Jewels, Silver, And Gold "precious," And Earth And Soil "base"?

The Vain Presumption Of Understanding Everything Can Have No Other Basis Than Never Having Understood Anything. For Anyone Who Had Ever Experienced Just Once The Perfect Understanding Of One Single Thing, And Had Truly Tasted How Knowledge Is Accomplished, Would Recognize That Of The Infinity Of Other Truths He Understands Nothing.

Showing A Greater Fondness For Their Own Opinions Than For Truth, They Sought To Deny And Disprove The New Things Which, If They Had Cared To Look For Themselves, Their Own Senses Would Have Demonstrated To Them.

And Believe Me, If I Were Again Beginning My Studies, I Should Follow The Advice Of Plato And Start With The Mathematical Sciences, Which Proceed Very Cautiously And Admit Nothing As Established Until It Has Been Rigorously Demonstrated.

Nature Is Written In Mathematical Language.
