Should I quote famous scientists in my SOP?

In one of Ben Bitdiddle's comment, he confirms that quoting famous scientists in the SOP is generally bad. But I don't know why. Isn't SOP the place to tell our stories, our inspirations, our motivations, our goals, etc? We scientists, who incur ourselves to solve the hardest problems of the world, are inspired by giant scientists, don't we? So I don't know why...
