Is the purpose of theoretical physics to be no more than a cataloging of all the things that can happen when particles interact with each other and separate? Or is it to be an understanding at a deeper level in which there are things that are not directly observable (as the underlying quantized fields are) but in terms of which we shall have a more fundamental understanding?

Philosophy treats of physics where a more careful knowledge is required because the problems which come under this head are numerous... So the reader of Ctesibius or Archimedes and the other writers of treatises of the same class will not be able to appreciate them unless he has been trained in these subjects by the philosophers.
Vitruvius
Weep for me, whoever has charity, truth and justice I did not come on this voyage for gain, honor or wealth, that is certain for then the hope of all such things was dead. I came to Your Highnesses with honest purpose and sincere zeal and I do not lie. I humbly beseech Your Highnesses that, if it please God to remove me hence, you will help me to go to Rome and on other pilgrimages.
Christopher Columbus
Sir, money, money, the most charming of all things money, which will say more in one moment than the most elegant lover can in years. Perhaps you will say a man is not young I answer he is rich. He is not genteel, handsome, witty, brave, good-humored, but he is rich, rich, rich, rich, rich that one word contradicts everything you can say against him.
Henry Fielding
When, in the course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume among the powers of the earth the separate and equal station to which the laws of nature and of nature's God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.
Thomas Jefferson
We grow great by dreams. All big men are dreamers. They see things in the soft haze of a spring day or in the red fire of a long winter's evening. Some of us let these dreams die, but others nourish and protect them nurse them through bad days till they bring them to the sunshine and light which comes always to those who hope that their dreams will come true.
