Religions that teach brotherly love have been used as an excuse for persecution, and our profoundest scientific insight is made into a means of mass destruction.

To teach how to live without certainty and yet without being paralysed by hesitation is perhaps the chief thing that philosophy, in our age, can do for those who study it.

Dogmatism and skepticism are both, in a sense, absolute philosophies; one is certain of knowing, the other of not knowing. What philosophy should dissipate is certainty, whether of knowledge or ignorance.

I think we ought always to entertain our opinions with some measure of doubt. I shouldn't wish people dogmatically to believe any philosophy, not even mine.

My dad is an electrical engineer. So he was always very focused on, you know, teaching his daughters about, you know, science, math, technology. None of us actually became engineers for our careers, but I always had that exposure when I was young, and I just loved playing computer games.

There were certain things that grabbed my interest, such as photosynthesis, such as us living off plants and plants living off us. You look at everything in that light - so if I'm looking at ice cubes, I might start thinking about absolute zero, or Fahrenheit and Celsius. There's so much that can make me think about science.

My desire to be a physician had a lot to do with that sense of medicine as a ministry of healing, not just a science. And not even just a science and an art, but also a calling, also a ministry.

I started out with the intention of studying physics. I was a terrible high school student outside of the fact that I did well in physics, but there's a big difference between being good at physics and being a physicist, so I jettisoned that very quickly.
