“The argument has long been made that we humans are by nature compassionate and empathic despite the occasional streak of meanness, but torrents of bad news throughout history have contradicted that claim, and little sound science has backed it. But try this thought experiment. Imagine the number of opportunities people around the world today might have to commit an antisocial act, from rape or murder to simple rudeness and dishonesty. Make that number the bottom of a fraction. Now for the top value you put the number of such antisocial acts that will actually occur today. That ratio of potential to enacted meanness holds at close to zero any day of the year. And if for the top value you put the number of benevolent acts performed in a given day, the ratio of kindness to cruelty will always be positive. (The news, however, comes to us as though that ratio was reversed.)Harvard's Jerome Kagan proposes this mental exercise to make a simple point about human nature: the sum total of goodness vastly outweighs that of meanness. 'Although humans inherit a biological bias that permits them to feel anger, jealousy, selfishness and envy, and to be rude, aggressive or violent,' Kagan notes, 'they inherit an even stronger biological bias for kindness, compassion, cooperation, love and nurture – especially toward those in need.' This inbuilt ethical sense, he adds, 'is a biological feature of our species.”

“The quality of moral behaviour varies in inverse ratio to the number of human beings involved.”

“The task of evolutionary psychology is not to weigh in on human nature, a task better left to others. It is to add the satisfying kind of insight that only science can provide: to connect what we know about human nature with the rest of our knowledge of how the world works, and to explain the largest number of facts with the smallest number of assumptions.”

“No matter how limited their powers of reason might have been. still they must have understood that living like that was just murder, a capital crime - except it was slow, day-by-day murder. The government (or humanity) could not permit capital punishment for one man, but they permitted the murder of millions a little at a time. To kill one man - that is, to subtract 50 years from the sum of all human lives - that was a crime; but to subtract from the sum of all human lives 50,000,000 years - that was not a crime! No, really, isn't it funny? This problem in moral math could be solved in half a minute by any ten-year-old Number today, but they couldn't solve it. All their Kant's together couldn't solve it (because it never occurred to one of their Kant's to construct a system of scientific ethics - that is, one based on subtraction, addition, division, and multiplication).”

“As I have earlier noted, the most important things in life and in business can’t be measured. The trite bromide 'If you can measure it, you can manage it' has been a hindrance in the building a great real-world organization, just as it has been a hindrance in evaluating the real-world economy. It is character, not numbers, that make the world go ‘round. How can we possibly measure the qualities of human existence that give our lives and careers meaning? How about grace, kindness, and integrity? What value do we put on passion, devotion, and trust? How much do cheerfulness, the lilt of a human voice, and a touch of pride add to our lives? Tell me, please, if you can, how to value friendship, cooperation, dedication, and spirit. Categorically, the firm that ignores the intangible qualities that the human beings who are our colleagues bring to their careers will never build a great workforce or a great organization.”

“The Hitchhiker's Guide to the Galaxy's definition of "Universe":The Universe is a very big thing that contains a great number of planets and a great number of beings. It is Everything. What we live in. All around us. The lot. Not nothing. It is quite difficult to actually define what the Universe means, but fortunately the Guide doesn't worry about that and just gives us some useful information to live in it. Area: The area of the Universe is infinite.Imports: None. This is a by product of infinity; it is impossible to import things into something that has infinite volume because by definition there is no outside to import things from.Exports: None, for similar reasons as imports.Population: None. Although you might see people from time to time, they are most likely products of your imagination. Simple mathematics tells us that the population of the Universe must be zero. Why? Well given that the volume of the universe is infinite there must be an infinite number of worlds. But not all of them are populated; therefore only a finite number are. Any finite number divided by infinity is zero, therefore the average population of the Universe is zero, and so the total population must be zero.Art: None. Because the function of art is to hold a mirror up to nature there can be no art because the Universe is infinite which means there simply isn't a mirror big enough. Sex: None. Although in fact there is quite a lot, given the zero population of the Universe there can in fact be no beings to have sex, and therefore no sex happens in the Universe.”
