“Unfairness builds character and brings diversity to the otherwise homogeneous and isotropic existence.”

“Since we only consider the universe on a very large scale, and make abstraction of all details and local irregularities, our universe must be homogeneous and isotropic. It follows… that the three-dimensional space of it must be what mathematicians call a space of constant curvature.”

Willem de Sitter (1872–1934) Dutch cosmologist

“By symmetry we mean the existence of different viewpoints from which the system appears the same. It is only slightly overstating the case to say that physics is the study of symmetry. The first demonstration of the power of this idea may have been by Newton, who may have asked himself the question: What if the matter here in my hand obeys the same laws as that up in the sky—that is, what if space and matter are homogeneous and isotropic?”

Philip Warren Anderson (1923) American physicist

“O body swayed to music, O brightening glance,
How can we know the dancer from the dance?”

W.B. Yeats book The Tower

Among School Children http://poetry.poetryx.com/poems/1437/, st. 8 The Tower (1928) Context: Labour is blossoming or dancing where The body is not bruised to pleasure soul. Nor beauty born out of its own despair, Nor blear-eyed wisdom out of midnight oil. O chestnut-tree, great-rooted blossomer, Are you the leaf, the blossom or the bole? O body swayed to music, O brightening glance, How can we know the dancer from the dance?

“In this conflict between youth and its elders, youth is the incarnation of reason pitted against the rigidity of tradition.”

Randolph Bourne (1886–1918) American writer

Quote republished in " Left and Right: The Prospects for Liberty http://alexpeak.com/twr/lar/1/1/2/," Left and Right: A Journal of Libertarian Thought 1, no. 1 (Spring, 1965), pp. 21 http://alexpeak.com/twr/lar/1/1/2/#p21– 22 http://alexpeak.com/twr/lar/1/1/2/#p22. "Youth" (1912), II Context: In this conflict between youth and its elders, youth is the incarnation of reason pitted against the rigidity of tradition. Youth puts the remorseless questions to everything that is old and established,—Why? What is this thing good for? And when it gets the mumbled, evasive answers of the elders, it applies its own fresh, clean spirit of reason to the institutions, customs, and ideas, and finding them stupid, inane, or poisonous, turns instinctively to overthrow them and build in their place the things with which its visions teem.
