Vulgarity begins when imagination succumbs to the explicit.

Under no stretch of imagination can war be regarded as an ethical process yet war, force, terror, and propaganda were the evolutionary means employed to weld the German people into a tribal whole.

I always believe it's better to have 30 imaginations working on a project, rather than one imagination telling the other 29 what to do.

I have enough love to last me a lifetime! Thank God I'll never lose my imagination and my passion. That's really what it is. I'm still passionate about what I do.

Clearly, some creative thinking is badly needed if humans are to have a future beyond Earth. Returning to the Moon may be worthy and attainable, but it fails to capture the public's imagination. What does get people excited is the prospect of a mission to Mars.
