None of the observations are more in point, as bearing on the doctrine of what Hooker terms 'creation by variation,' than the great extent to which the internal characters and properties of plants, or their physiological constitution are capable of being modified, while they exhibit externally no visible departure from the normal form. ...When several of these internal or physiological modifications are accompanied by variation in size, habits of growth, colour of the flowers, and other external characters, and these are found to be constant in successive generations, botanists may well begin to differ in opinion as to whether they ought to regard them as distinct species or not.

The object of this Essay is to explain as clearly as I am able grounds of an opinion which I have held from the very earliest period when I had formed any opinions at all on social political matters, and which, instead of being weakened or modified, has been constantly growing stronger by the progress reflection and the experience of life. That the principle which regulates the existing social relations between the two sexes - the legal subordination of one sex to the other - is wrong itself, and now one of the chief hindrances to human improvement; and that it ought to be replaced by a principle of perfect equality, admitting no power or privilege on the one side, nor disability on the other.
John Stuart Mill
But how to write about a man who lived such a contemplative life marked by so few striking external events? He was extraordinarily private, and he kept his own person invisible in his writing. I had none of the material that ordinarily lends itself to narrative-no family dramas, no love affairs, jealousies, curious anecdotes, feuds, spats, or reunions. He had a large correspondence, but after his death his colleagues followed his instructions and removed almost all personal comments from his letters. No, not much external drama in his life: most scholars regard Spinoza as a placid and gentle soul-some compare his life to that of Christian saints, some even to Jesus.
Baruch Spinoza
Constitution,-the apex of all its intelligences and mighty instincts and dumb longings: it is I? William Conqueror's big gifts, and Edward's and Elizabeth's; Oliver's lightning soul, noble as Sinai and the thunders of the Lord: these are mine, I begin to perceive,-to a certain extent. These heroisms have I,-though rather shy of exhibiting them. These; and something withal of the huge beaver-faculty of our Arkwrights, Brindleys; touches too of the phoenix-melodies and sunny heroisms of our Shakspeares, of our Singers, Sages and inspired Thinkers all this is in me, I will hope,-though rather shy of exhibiting it on common occasions.
Thomas Carlyle
The aesthetics of painting were always in a state of development parallel to the development of painting itself. They influenced each other and vice versa. But all of the sudden, in that famous turn of the century [1900] a few people thought they could take the bull by the horns and invent an aesthetic beforehand. After immediately disagreeing with each other, they began to form all kinds of groups, each with the idea of freeing art... The question as they saw it, was not so much what you could paint, but what you could not paint. You could not paint a house or a tree or a mountain. It was then that the subject matter came into existence as something you ought not to have.
Willem de Kooning
Since the Gothic, European sculpture had become overgrown with moss, weeds – all sorts of surface excrescences which completely concealed shape. It has been Brancusi's special mission to get rid of this overgrowth, and make us once more shape-conscious. To do this he has had to concentrate on very simple direct shapes, to keep his sculpture, as it were, one-cylindered, to refine and polish a single shape to a degree almost too precious.. ..it may now be no longer necessary to close down and restrict sculpture to the single form unit. We can now begin to open out. To relate and combine together several forms of varied sizes, sections, and directions into one organic whole.
