Oftentimes, those special brains, the ones that are capable of focusing more intently than others, do so at the expense of emotional maturity

Our society’s love affair with mechanical devices that respond at a button-touch ill prepares us to deal with the unruly organic mind that dwells within. Anything that does not comply must be broken or poorly designed, people now suppose, including their hearts.

If our well-being depends upon the interaction between events in our brains and events in the world, and there are better and worse ways to secure it, then some cultures will tend to produce lives that are more worth living than others; some political persuasions will be more enlightened than others; and some world views will be mistaken in ways that cause needless human misery.

Everything a person is and everything he knows resides in the tangled thicket of his intertwined neurons. These fateful, tiny bridges number in the quadrillions, but they spring from just two sources: DNA and daily life. The genetic code calls some synapses into being, while experience engenders and modifies others.

Jumping to conclusions is efficient if the conclusions are likely to be correct and the costs of an occasional mistake acceptable. Jumping to conclusions is risky when the situation is unfamiliar, the stakes are high and there is no time to collect more information.

It's a general moral principle that the more power you have over someone, the greater your duty to use that power benevolently. Well, who is the one person in the world you have the greatest power over? It's your future self. You hold that life in your hands, and what it will be depends on how you care for it.

Taking in the good is not about putting a happy shiny face on everything, nor is it about turning away from the hard things in life. It's about nourishing well-being, contentment, and peace inside that are refuges you can always come from and return to.

our moral reasoning is plagued by two illusions. The first illusion can be called the wag-the-dog illusion: We believe that our own moral judgment (the dog) is driven by our own moral reasoning (the tail). The second illusion can be called the wag-theother-dog's-tail illusion: In a moral argument, we expect the successful rebuttal of an opponent's arguments to change the opponent's mind. Such a belief is like thinking that forcing a dog's tail to wag by moving it with your hand will make the dog happy.

One brain’s blueprint may promote joy more readily than most; in another, pessimism reigns. Whether happiness infuses or eludes a person depends, in part, on the DNA he has chanced to receive.

[I]f you can be with the pleasant without chasing after it, with the unpleasant without resisting it, and with the neutral without ignoring it - [...] that is an incredible [...] freedom.

[K]eep in mind the big picture, the 1,000-foot view. See the impermanence of whatever is at issue, and the many causes and conditions that led to it. See the collateral damage - the suffering - that results when you cling to your desires and opinions or take things personally. Over the long haul, most of what we argue about with others really doesn't matter that much.

When people have trouble with their emotions – a bout of anxiety or depression, say, or seasonal gloominess - they often want science to pinpoint an offending neurotransmitter in the way that a witness picks the perp out of a lineup. Is it excessive norepinephrine, too little dopamine, errant estrogen? The answer is apt to dissatisfy: no single suspect can be fingered with confidence because the question itself attributes a fallacious simplicity to the brain.

The linear size of a neuron varies widely from one nerve cell to the other, since some of these cells are contained in closely integrated large aggregates and have, therefore, very short axons, while others conduct pulses between rather remote parts of the body and may, therefore, have linear extensions comparable to those of the entire human body.
