Ere many generations pass, our machinery will be driven by a power obtainable at any point of the universe. This idea is not novel. Men have been led to it long ago by instinct or reason; it has been expressed in many ways, and in many places, in the history of old and new. We find it in the delightful myth of Antaeus, who derives power from the earth; we find it among the subtle speculations of one of your splendid mathematicians and in many hints and statements of thinkers of the present time. Throughout space there is energy. Is this energy static or kinetic! If static our hopes are in vain; if kinetic — and this we know it is, for certain — then it is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature.
Our virtues and our failings are inseparable, like force and matter. When they separate, man is no more.
Of all the frictional resistances, the one that most retards human movement is ignorance, what Buddha called 'the greatest evil in the world.' The friction which results from ignorance ... can be reduced only by the spread of knowledge and the unification of the heterogeneous elements of humanity. No effort could be better spent.
Waterloo will wipe out the memory of my forty victories; but that which nothing can wipe out is my Civil Code. That will live forever.
With Heaven's aid I have conquered for you a huge empire. But my life was too short to achieve the conquest of the world. That task is left for you.
I don't know if I particularly want to be remembered for anything. I have enjoyed great satisfaction from my climb of Everest and my trips to the poles. But there's no doubt, either, that my most worthwhile things have been the building of schools and medical clinics. That has given me more satisfaction than a footprint on a mountain.
