Convergence is, in my opinion, not only deeply fascinating but, curiously, it is as often overlooked. More importantly, it hints at the existence of a deeper structure to biology. It helps us to delineate a metaphorical map across which evolution must navigate. In this sense the Darwinian mechanisms and the organic substrate we call life are really a search engine to discover particular solutions, including intelligence and-risky thought-perhaps deeper realities?

But those rare souls whose spirit gets magically into the hearts of men, leave behind them something more real and warmly personal than bodily presence, an ineffable and eternal thing. It is everlasting life touching us as something more than a vague, recondite concept. The sound of a great name dies like an echo the splendor of fame fades into nothing but the grace of a fine spirit pervades the places through which it has passed, like the haunting loveliness of mignonette.
James Thurber
In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time someting like that happened in politics or religion.
Carl Sagan
Such is the common process of marriage. A youth and maiden meeting by chance, or brought together by artifice, exchange glances, reciprocate civilities, go home, and dream of one another. Having little to divert attention, or diversify thought, they find themselves uneasy when they are apart, and therefore conclude that they shall be happy together. They marry, and discover what nothing but voluntary blindness had before concealed; they wear out life in altercations, and charge nature with cruelty.
Samuel Johnson
However great a man's fear of life, suicide remains the courageous act, the clear-headed act of a mathematician. The suicide has judged by the laws of chance -- so many odds against one that to live will be more miserable than to die. His sense of mathematics is greater than his sense of survival. But think how a sense of survival must clamor to be heard at the last moment, what excuses it must present of a totally unscientific nature.
Graham Greene
A social aggregate which has chosen the fatal path of organic evolution must succumb to the same law of organic development to which all organisms are subject, namely greater and greater organization, increase of structure, greater differentiation, decrease of critical, personal, consciousness, loss of individual liberty, increased activity of the subconscious forces, falling into a state of somnambulism which can only be redeemed by revolution or by death.
