It Has Always Irked Me As Improper

As Far As I Know, There Is No Proof Whatever Of The Existence Of An Objective Reality Apart From Our Senses, And I Do Not See Why We Should Accept The Outside World As Such Solely By Virtue Of Our Senses.

For Me It Remains An Open Question Whether [this Work] Pertains To The Realm Of Mathematics Or To That Of Art.

Although I Am Even Now Still A Layman In The Area Of Mathematics, And Although I Lack Theoretical Knowledge, The Mathematicians, And In Particular The Crystallographers, Have Had Considerable Influence On My Work Of The Last Twenty Years. The Laws Of The Phenomena Around Us--order, Regularity, Cyclical Repetition, And Renewals--have Assumed Greater And Greater Importance For Me. The Awareness Of Their Presence Gives Me Peace And Provides Me With Support. I Try In My Prints To Testify That We Live In A Beautiful And Orderly World, And Not In A Formless Chaos, As It Sometimes Seems.

I Am Always Wandering Around In Enigmas. There Are Young People Who Constantly Come To Tell Me: You, Too, Are Making Op Art. I Haven't The Slightest Idea What That Is, Op Art. I've Been Doing This Work For Thirty Years Now.

By Keenly Confronting The Enigmas That Surround Us, And By Considering And Analyzing The Observations That I Had Made, I Ended Up In The Domain Of Mathematics. Although I Am Absolutely Without Training In The Exact Sciences, I Often Seem To Have More In Common With Mathematicians Than With My Fellow Artists.
