“Yon Cassius has a lean and hungry look. He thinks too much. Such men are dangerous.”

Gee, I don't know...he could be describing DaVinci here. ?

I guess it matters as to the thinker. The thinkers of the statist theocracy that now infest this land had to think long, hard and much to become such a danger to freedom, liberty, and the rights of man. However, that quintessence that is the soul of man is once again awakening, causing men to think much on how to restore freedom, liberty, and rights. That is a danger to the statist theocracy.

Strangely dangerous men of today do not always look mean and hungry. They can instead be well fed and winsome, at leat fro some, if not for all.

Especially if they are quiet

Harry Reed looks lean and hungry. As to his thinking , I 'm not sure, but he is definitly dangerous.
