The questions of philosophy proper are human desires and fears and aspirations - human emotions - taking an intellectual form.

We receive the truths of science by compulsion. Nothing but ignorance is able to resist them.

All observers not laboring under hallucinations of the senses are agreed, or can be made to agree, about facts of sensible experience, through evidence toward which the intellect is merely passive, and over which the individual will and character have no control.

If they are, then the only ultimate truths are the particulars of concrete experience, and no postulate or general assumption is inherent in science until its proceedings become systematic, or the truths already reached give direction to further research.

I was a science fiction geek from an early age, enthralled by the questions of life in the universe. As I got older, I learned that space exploration was real. I wanted to get involved in that. I knew I wanted to be a scientist.

Imagination is the Discovering Faculty, pre-eminently. It is that which penetrates into the unseen worlds around us, the worlds of Science.

I think sometimes people can get lost in the bigger special effects, science fiction, robot stuff, and those are cool and fun to watch, too, but I think it's so important to sometimes step back and watch something that's about life and human interaction.

Physics is perceived as a lonesome, nerdy kind of enterprise that has very little to do with human feelings and the things that excite people day-to-day about each other. Yet physicists in their own working environment are very social creatures.
