Need We Add That Mathematicians Themselves Are

. . . By Natural Selection Our Mind Has Adapted Itself To The Conditions Of The External World. It Has Adopted The Geometry Most Advantageous To The Species Or, In Other Words, The Most Convenient. Geometry Is Not True, It Is Advantageous.

But For Harmony Beautiful To Contemplate, Science Would Not Be Worth Following.

It Is Far Better To Foresee Even Without Certainty Than Not To Foresee At All.

In The Old Days When People Invented A New Function They Had Something Useful In Mind.

If We Wish To Foresee The Future Of Mathematics, Our Proper Course Is To Study The History And Present Condition Of The Science.
