What We Makes Of The World Must Be Largely Dependent On The Sense-organs That We Happen To Possess. How The World Must Have Changed Since The Man Came To Rely On His Eyes Rather Than His Nose.

To The Pure Geometer The Radius Of Curvature Is An Incidental Characteristic - Like The Grin Of The Cheshire Cat. To The Physicist It Is An Indispensable Characteristic. It Would Be Going Too Far To Say That To The Physicist The Cat Is Merely Incidental To The Grin. Physics Is Concerned With Interrelatedness Such As The Interrelatedness Of Cats And Grins. In This Case The "cat Without A Grin" And The "grin Without A Cat" Are Equally Set Aside As Purely Mathematical Phantasies.

Philosophically, The Notion Of A Beginning Of The Present Order Of Nature Is Repugnant To Me ... I Should Like To Find A Genuine Loophole.

A Star Is Drawing On Some Vast Reservoir Of Energy By Means Unknown To Us. This Reservoir Can Scarcely Be Other Than The Subatomic Energy Which, It Is Known Exists Abundantly In All Matter; We Sometimes Dream That Man Will One Day Learn How To Release It And Use It For His Service. The Store Is Well Nigh Inexhaustible, If Only It Could Be Tapped. There Is Sufficient In The Sun To Maintain Its Output Of Heat For 15 Billion Years.

Unless The Structure Of The Nucleus Has A Surprise In Store For Us, The Conclusion Seems Plain — There Is Nothing In The Whole System Of Laws Of Physics That Cannot Be Deduced Unambiguously From Epistemological Considerations.
