It Is One Thing For The Human Mind To Extract From The Phenomena Of Nature The Laws Which It Has Itself Put Into Them; It May Be A Far Harder Thing To Extract Laws Over Which It Has No Control. It Is Even Possible That Laws Which Have Not Their Origin In The Mind May Be Irrational, And We Can Never Succeed In Formulating Them.

Man Is Slightly Nearer To The Atom Than To The Star. ... From His Central Position Man Can Survey The Grandest Works Of Nature With The Astronomer, Or The Minutest Works With The Physicist. ... [k]nowledge Of The Stars Leads Through The Atom; And Important Knowledge Of The Atom Has Been Reached Through The Stars.

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.
