“Of course genes can’t pull the levers of our behavior directly. But they affect the wiring and workings of the brain, and the brain is the seat of our drives, temperaments and patterns of thought. Each of us is dealt a unique hand of tastes and aptitudes, like curiosity, ambition, empathy, a thirst for novelty or for security, a comfort level with the social or the mechanical or the abstract. Some opportunities we come across click with our constitutions and set us along a path in life.”

“We must allow the Word of God to confront us, to disturb our security, to undermine our complacency and to overthrow our patterns of thought and behavior.”

“Schwartz's research suggests something important: we can stretch our personalities, but only up to a point. Our inborn temperaments influence us, regardless of the lives we lead. A sizeable part of who we are is ordained by our genes, by our brains, by our nervous systems. And yet the elasticity that Schwartz found in some of the high-reactive teens also suggests the converse: we have free will and can use it to shape our personalities.”

“Inside our skulls are fish, reptile and shrew brains, as well as the highest centers that allow us to integrate information in our unique way; and some of our newer brain components talk to each other via some very ancient structures indeed. Our brains are makeshift structures, opportunistically assembled by Nature over hundreds of millions of years, and in multiple different ecological contexts.”

“Even though its common knowledge these days, it never ceases to amaze me that all the richness of our mental life - all our feelings, our emotions, our thoughts, our ambitions, our love life, our religious sentiments and even what each of us regards us his own intimate private self - is simply the activity of these little specks of jelly in your head, in your brain. There is nothing else.”

“Life will undertake to separate us, and we must each set off in search of our own path, our own destiny or our own way of facing death.”
