"For me, consciousness is the most interesting unsolved problem of science, and, in fact, we may never know what it is about a particular arrangement of neurons that gives rise to consciousness. Our consciousness, like the air we breathe or like the passage of time, is central to our existence as intelligent beings."

It is characteristic of genius to be hopeful and aspiring. It is characteristic of genius to break up the artificial arrangements of conventionalism, and to view mankind in true perspective, in their gradations of inherent rather than of adventitious worth. Genius is therefore essentially democratic, and has always been so.

— Harriet Martineau
