Giraffes do use their long necks to browse leaves, at the tops of acacia trees - but such current function, no matter how vital, does not prove that the neck originally evolved for this purpose. The neck may have first lengthened in context of a different use, and then been coopted for better dining when giraffes moved into the open plains. Or the neck may have evolved to perform several functions at once. We cannot learn the reasons for historical origin simply by listing current uses.

Depth, in a pictorial, plastic sense, is not created by the arrangement of objects one after another toward a vanishing point, in the sense of the Renaissance perspective, but on the contrary (and in absolute denial of this doctrine) by the creation of forces in the sense of push and pull . Nor is depth created by tonal gradation (another doctrine of the academician which, at its culmination, degraded the use of color to a mere function of expressing dark and light).
Hans Hofmann
I assert once again as a truth to which history as a whole bears witness that men may second their fortune, but cannot oppose it; that they may weave its warp, but cannot break it. Yet they should never give up, because there is always hope, though they know not the end and more towards it along roads which cross one another and as yet are unexplored; and since there is hope, they should not despair, no matter what fortune brings or in what travail they find themselves.
Niccolò Machiavelli
Men call women faithless, changeable, and though they say it in jealousy of their own ever-threatened sexual honor, there is some truth in it. We can change our life, our being; no matter what our will is, we are changed. As the moon changes yet is one, so we are virgin, wife, mother, grandmother. For all their restlessness, men are who they are; once they put on the man's toga they will not change again; so they make a virtue of that rigidity and resist whatever might soften it and set them free.
Ursula K. Le Guin
Once, when I was younger, I thought I could be someone else. I'd move to Casablanca, open a bar, and I'd meet Ingrid Bergman. Or more realistically - whether actually more realistic or not - I'd tune in on a better life, something more suited to my true self. Toward that end, I had to undergo training. I read The Greening of America, and I saw Easy Rider three times. But like a boat with a twisted rudder, I kept coming back to the same place. I wasn't anywhere. I was myself, waiting on the shore for me to return.
Haruki Murakami
There is no coherent knowledge, i. e. no uniform comprehensive account of the world and the events in it. There is no comprehensive truth that goes beyond an enumeration of details, but there are many pieces of information, obtained in different ways from different sources and collected for the benefit of the curious. The best way of presenting such knowledge is the list - and the oldest scientific works were indeed lists of facts, parts, coincidences, problems in several specialized domains.
