The ancient Greeks knew the laws that govern the propagation of light in a uniform medium and upon its reflection. However, the law governing the refraction of light as it passes from one transparent medium to another was unknown until the last century. Snell discovered it, Descartes tried to explain it and Fermat criticized his explanation. Since then, many great geometers have researched the problem, although no one has yet found a way of harmonizing the law of refraction with more fundamental laws that Nature must obey.

We cannot point to a single definitive solution of any one of the problems that confront us - political, economic, social or moral, that is, having to do with the conduct of life. We are still beginners, and for that reason may hope to improve. To deride the hope of progress is the ultimate fatuity, the last word in poverty of spirit and meanness of mind. There is no need to be dismayed by the fact that we cannot yet envisage a definitive solution of our problems, a resting-place beyond which we need not try to go.
Peter Medawar
That in all capital or criminal prosecutions a man bath a right to demand the cause and nature of his accusation, to be confronted with the accusers and witnesses, to call for evidence in his favor, and to a speedy trial by an impartial jury of twelve men of his vicinage, without whose unanimous consent he cannot be found guilty; nor can he be compelled to give evidence against himself; that no man be deprived of his liberty, except by the law of the land or the judgment of his peers.
George Mason
Daily the Negro is coming more and more to look upon law and justice, not as protecting safeguards, but as sources of humiliation and oppression. The laws are made by men who have little interest in him; they are executed by men who have absolutely no motive for treating the black people with courtesy and consideration; and, finally, the accused law-breaker is tried, not by his peers, but too often by men who would rather punish ten innocent Negroes than let one guilty one escape.
W. E. B. Du Bois
In the depths of the mirror the evening landscape moved by, the mirror and the reflected figures like motion pictures superimposed one on the other. The figures and the background were unrelated, and yet the figures, transparent and intangible, and the background, dim in the gathering darkness, melted into a sort of symbolic world not of this world. Particularly when a light out in the mountains shone in the center of the girl's face, Shimamura felt his chest rise at the inexpressible beauty of it.
Yasunari Kawabata
Yet I am not more sure that my soul lives, than I am that perverseness is one of the primitive impulses of the human heart - one of the indivisible primary faculties, or sentiments, which give direction to the character of man. Who has not, a hundred times, found himself committing a vile or a stupid action, for no other reason than because he knows he should not? Have we not a perpetual inclination, in the teeth of our best judgement, to violate that which is Law, merely because we understand it to be such?
Edgar Allan Poe
