“It's a mystery of human chemistry and I don't understand it, some people, as far as their senses are concerned, just feel like home.”

“Let me tell you, you either have chemistry or you don't, and you better have it, or it's like kissing some relative. But chemistry, listen to me, you got to be careful. Chemistry is like those perfume ads, the ones that look so interesting and mysterious but you dont even know at first what they're even selling. Or those menues without the prices. Mystery and intrigue are gonna cost you. Great looking might mean something ve-ry expensive, and I don't mean money. What I'm saying is, chemistry is a place to start, not an end point.”

“Yes," Marcus says. "I understand that you are concerned -- that you all are concerned. You had never heard of the Divergent a week ago, and now all that you know is that they are immune to something to which you are susceptible, and that is a frightening thing. But I can assure you that there is nothing to be afraid of, as far as we are concerned."As he speaks, his head tilts and his eyebrows lift in sympathy, and I understand at once why some people like him. He makes you feel that if you just placed everything in his hands, he would take care of it.”

“There is no such thing as a weird human being, It's just that some people require more understanding than others.”

“Science is part of culture. Culture isn't only art and music and literature, it's also understanding what the world is made of and how it functions. People should know something about stars, matter and chemistry. People often say that they don't like chemistry but we deal with chemistry all the time. People don't know what heat is, they hardly know what water is. I'm always surprised how little people know about anything. I'm puzzled by it.”

“People think of life as being so sacred and they feel like this is their only chance and they have to do something with their life and make an impact As far as I'm concerned, it's just a pitstop for the afterlife. It's just a little test to see how you can handle reality.”
