Paulo Coelho's "The Alchemist"

"Because it's not love to be static like the desert, nor is it love to roam the world like the wind. And it's not love to see everything from a distance, like you do. Love is the force that transforms and improves the Soul of the World. When I first reached through to it, I thought the Soul of the World was perfect. But later, I could see that it was like other aspects of creation, and had its own passions and wars. It is we who nourish the Soul of the World, and the world we live in will be either better or worse, depending on whether we become better or worse. And that's where the power of love comes in. Because when we love, we always strive to become better than we are."

Descartes' 3rd Maxim: "Conquer Yourself"

"My third maxim was to endeavor always to conquer myself rather than fortune, and change my desires rather than the order of the world, and in general, accustom myself to the persuasion that, except our own thoughts, there is nothing absolutely in our power; so that when we have done our best in things external to us, all wherein we fail of success is to be held, as regards us, absolutely impossible: and this single principle seemed to me sufficient to prevent me from desiring for the future anything which I could not obtain, and thus render me contented; for since our will naturally seeks those objects alone which the understanding represents as in some way possible of attainment, it is plain, that if we consider all external goods as equally beyond our power, we shall no more regret the absence of such goods as seem due to our birth, when deprived of them without any fault of ours, than our not possessing the kingdoms of China or Mexico, and thus making, so to speak, a virtue of necessity, we shall no more desire health in disease, or freedom in imprisonment, than we now do bodies incorruptible as diamonds, or the wings of birds to fly with. But I confess there is need of prolonged discipline and frequently repeated meditation to accustom the mind to view all objects in this light; and I believe that in this chiefly consisted the secret of the power of such philosophers as in former times were enabled to rise superior to the influence of fortune, and, amid suffering and poverty, enjoy a happiness which their gods might have envied. For, occupied incessantly with the consideration of the limits prescribed to their power by nature, they became so entirely convinced that nothing was at their disposal except their own thoughts, that this conviction was of itself sufficient to prevent their entertaining any desire of other objects; and over their thoughts they acquired a sway so absolute, that they had some ground on this account for esteeming themselves more rich and more powerful, more free and more happy, than other men who, whatever be the favors heaped on them by nature and fortune, if destitute of this philosophy, can never command the realization of all their desires."

Descarte's 2nd Maxim: Be firm & resolute in actions and decisions

"My second maxim was to be as firm and resolute in my actions as I was able, and not to adhere less steadfastly to the most doubtful opinions, when once adopted, than if they had been highly certain; imitating in this the example of travelers who, when they have lost their way in a forest, ought not to wander from side to side, far less remain in one place, but proceed constantly towards the same side in as straight a line as possible, without changing their direction for slight reasons, although perhaps it might be chance alone which at first determined the selection; for in this way, if they do not exactly reach the point they desire, they will come at least in the end to some place that will probably be preferable to the middle of a forest. In the same way, since in action it frequently happens that no delay is permissible, it is very certain that, when it is not in our power to determine what is true, we ought to act according to what is most probable; and even although we should not remark a greater probability in one opinion than in another, we ought notwithstanding to choose one or the other, and afterwards consider it, in so far as it relates to practice, as no longer dubious, but manifestly true and certain, since the reason by which our choice has been determined is itself possessed of these qualities. This principle was sufficient thenceforward to rid me of all those repentings and pangs of remorse that usually disturb the consciences of such feeble and uncertain minds as, destitute of any clear and determinate principle of choice, allow themselves one day to adopt a course of action as the best, which they abandon the next, as the opposite."

The Descent of Agriculture [Jared Diamond]

“Hunter-gatherers practised the most successful and long-persistent lifestyle in the career of our species. In contrast, we are still struggling with the problems into which we descended with agriculture, and it is unclear whether we can solve them. Suppose that an archaeologist who had visited us from outer space were trying to explain human history to his fellow spacelings. The visitor might illustrate the results of his digs by a twenty-four-hour clock on which one hour of clock-time represents 100,000 years of real past time. If the history of the human race began at midnight, then we would now be almost at the end of our first day. We lived as hunter-gatherers for nearly the whole of that day, from midnight through dawn, noon, and sunset. Finally, at 11:54 pm we adopted agriculture. In retrospect, the decision was inevitable, and there is now no question of turning back. But as our second midnight approaches, will the present plight of African peasants gradually spread to engulf all of us? Or, will we somehow achieve those seductive blessings that we imagine behind agriculture’s glittering facade, and that have so far eluded us except in mixed form?”

In search of stimuli

"If the brain were unable to fill in gaps and bet on meagre evidence, activity as a whole would come to a halt in the absence of sensory inputs. In fact we may slow down and act with action in the dark, or in unfamiliar surroundings, but life goes on and we are not powerless to act. Of course we are more likely to make mistakes ... but this is a small price to pay for gaining freedom from immediate stimuli determining behavior, as in simple animals which are helpless in unfamiliar surroundings. A frog may starve to death surrounded by dead flies; for behavior ceases when imagination cannot replace absent stimuli."

Jose Saramago - Blindness

"On their way to the home of the girl with dark glasses, they crossed a large square with groups of blind people who were listening to speeches from other blind people, at first sight, neither one nor the other group seemed blind, the speakers turned their heads excitedly towards their listeners, the listeners turned their heads attentively to the speakers. They were proclaiming the end of the world, redemption through penitence, the visions of the seventh day, the advent of the angel, cosmic collisions, the death of the sun, the tribal spirit, the sap of the mandrake, tiger ointment, the virtue of the sign, the discipline of the wind, the perfume of the moon, the revindication of darkness, the power of exorcism, the sign of the heel, the crucifixion of the rose, the purity of the lymph, the blood of the black cat, the sleep of the shadow, the rising of the seas, the logic of anthropopagy, painless castration, divine tattoos, voluntary blindness, convex thoughts, or concave, or horizontal or vertical, or sloping, or concentrated, or dispersed, or fleeting, the weakening of the vocal cords, the death of the word, Here noboy is speaking of organisation, said the doctor's wife, Perhaps organisation is in another square, he replied."

Alvin Toffler - The Third Wave

"Today I believe we stand on the edge of a new age of synthesis. In all intellectual fields, from the hard sciences to sociology, psychology, and economics - especially economics - we are likely to see a return to large-scale thinking, to general theory, to the putting of the pieces back together again. For it is beginning to dawn on us that our obsessive emphasis on quantified detail without context, on progressively finer and finer measurement of smaller and smaller problems, leaves us knowing more and more about less and less."
