An open mind but not an empty head.

The speculative part of my work is that these particular cognitive tasks - ways of thinking analytically - are tied to nature's laws.

The minimum we should hope for with any display technology is that it should do no harm.

I am certainly not an intellectual relativist, nor a moral relativist.

The best graphics are about the useful and important, about life and death, about the universe. Beautiful graphics do not traffic with the trivial.

The goal is to provide analytical tools that will last students a lifetime

I do believe that there are some universal cognitive tasks that are deep and profound - indeed, so deep and profound that it is worthwhile to understand them in order to design our displays in accord with those tasks.
