Most people have learned to live in the moment. The argument goes that if the past has uncertain effect on the present, there is no need to dwell on the past. And if the present has little effect on the future, present actions need not be weighed for their consequence. Rather, each act is an island in time, to be judged on its own. ... It is a world of impulse. It is a world of sincerity. It is a world in which every word spoken speaks just to that moment, every glance given has only one meaning.
I am exclusively occupied with the problem of gravitation and hope with the help of a local mathematician friend [Marcel Grossman] to overcome all the difficulties. One thing is certain, however, that never in life have I been quite so tormented. A great respect for mathematics has been instilled within me, the subtler aspects of which, in my stupidity, I regarded until now as pure luxury.
For there is a great difference in delivery of the mathematics , which are the most abstracted of knowledges, and policy , which is the most immersed. And howsoever contention hath been moved , touching a uniformity of method in multiformity of matter, yet we see how that opinion, besides the weakness of it, hath been of ill desert towards learning, as that which taketh the way to reduce learning to certain empty and barren generalities; being but the very husks and shells of sciences, all the kernel being forced out and expulsed with the torture and press of the method.
The most important experiences a man can have are those that take him to the very limit; that is the only way we learn, because it requires all our courage.
Enflamed with the study of learning and the admiration of virtue; stirred up with high hopes of living to be brave men and worthy patriots, dear to God, and famous to all ages.
He who knows much about others may be learned, but he who understands himself is more intelligent. He who controls others may be powerful, but he who has mastered himself is mightier still.
No matter how much we learn, there is always more knowledge to be gained. In this connection I am reminded of a short poem that has been in my mind over the years. It reads as follow: I used to think I knew I knew. But now I must confess. The more I know I know I know I know I know the less.
Trace Science, then, with Modesty thy guide,
First strip off all her equipage of Pride,
Deduct what is but Vanity or Dress,
Or Learning's Luxury or idleness,
Or tricks, to show the stretch of the human brain
Mere curious pleasure or ingenious pain.
The good man is the teacher of the bad, And the bad is the material from which the good may learn. He who does not value the teacher, Or greatly care for the material, Is greatly deluded although he may be learned. Such is the essential mystery.
