How, then, can terrorists hope to achieve much? Following an act of terrorism, the enemy continues to have the same number of soldiers, tanks and ships as before. The enemy’s communication network, roads and railways are largely intact. His factories, ports and bases are hardly touched. However, the terrorists hope that even though they can barely dent the enemy’s material power, fear and confusion will cause the enemy to misuse his intact strength and overreact. Terrorists calculate that when the enraged enemy uses his massive power against them, he will raise a much more violent military and political storm than the terrorists themselves could ever create. During every storm, many unforeseen things happen. Mistakes are made, atrocities are committed, public opinion wavers, neutrals change their stance, and the balance of power shifts.

Nothing captures the biological argument better than the famous New Age slogan: ‘Happiness begins within.’ Money, social status, plastic surgery, beautiful houses, powerful positions – none of these will bring you happiness. Lasting happiness comes only from serotonin, dopamine and oxytocin.

Money is the most universal and most efficient system of mutual trust ever devised.

The assertion that religion is a tool for preserving social order and for organising large-scale cooperation may vex many people for whom it represents first and foremost a spiritual path. However, just as the gap between religion and science is smaller than we commonly think, so the gap between religion and spirituality is much bigger. Religion is a deal, whereas spirituality is a journey. Religion gives a complete description of the world, and offers us a well-defined contract with predetermined goals. ‘God exists. He told us to behave in certain ways. If you obey God, you’ll be admitted to heaven. If you disobey Him, you’ll burn in hell.’ The very clarity of this deal allows society to define common norms and values that regulate human behaviour. Spiritual journeys are nothing like that. They usually take people in mysterious ways towards unknown destinations. The quest usually begins with some big question, such as who am I? What is the meaning of life? What is good? Whereas many people just accept the ready-made answers provided by the powers that be, spiritual seekers are not so easily satisfied. They are determined to follow the big question wherever it leads, and not just to places you know well or wish to visit. Thus for most people, academic studies are a deal rather than a spiritual journey, because they take us to a predetermined goal approved by our elders, governments and banks.

religion is created by humans rather than by gods, and it is defined by its social function rather than by the existence of deities. Religion is anything that confers superhuman legitimacy on human social structures. It legitimises human norms and values by arguing that they reflect superhuman laws.

Cultures are mental parasites that emerge accidentally, and thereafter take advantage of all people infected by them.

Politics, too, is a second-order chaotic system. Many people criticise Sovietologists for failing to predict the 1989 revolutions and castigate Middle East experts for not anticipating the Arab Spring revolutions of 2011. This is unfair. Revolutions are, by definition, unpredictable. A predictable revolution never erupts.

In fact, monotheism, as it has played out in history, is a kaleidoscope of monotheist, dualist, polytheist and animist legacies, jumbling together under a single divine umbrella. The average Christian believes in the monotheist God, but also in the dualist Devil, in polytheist saints, and in animist ghosts. Scholars of religion have a name for this simultaneous avowal of different and even contradictory ideas and the combination of rituals and practices taken from different sources. It’s called syncretism. Syncretism might, in fact, be the single great world religion.

In 2012 about 56 million people died throughout the world; 620,000 of them died due to human violence (war killed 120,000 people, and crime killed another 500,000). In contrast, 800,000 committed suicide, and 1.5 million died of diabetes. Sugar is now more dangerous than gunpowder.

To run fast, don’t take much baggage with you. Leave all your illusions behind. They are very heavy.

Not only rationality, but individuality too is a myth. Humans rarely think for themselves. Rather, we think in groups. Just as it takes a tribe to raise a child, it also takes a tribe to invent a tool, solve a conflict, or cure a disease. No individual knows everything it takes to build a cathedral, an atom bomb, or an aircraft. What gave Homo sapiens an edge over all other animals and turned us into the masters of the planet was not our individual rationality but our unparalleled ability to think together in large groups.1

This is the essence of the Agricultural Revolution: the ability to keep more people alive under worse conditions.

The currency of evolution is neither hunger nor pain, but rather copies of DNA helixes. Just as the economic success of a company is measured only by the number of dollars in its bank account, not by the happiness of its employees, so the evolutionary success of a species is measured by the number of copies of its DNA.

If you are really in love with someone, you never worry about the meaning of life.

Terrorists are like a fly that tries to destroy a china shop. The fly is so weak that it cannot budge even a single teacup. So it finds a bull, gets inside its ear and starts buzzing. The bull goes wild with fear and anger, and destroys the china shop. (p.21)
