"Thus shadow owes its birth to light."

A shadow is a dark area on a surface where light from a light source is blocked by an object. In contrast, shade occupies the three-dimensional volume behind an object with light in front of it. The cross-section of a shadow is a two-dimensional silhouette, or a reverse projection of the object blocking the light.

"There are no shadows in the dark. Shadows are the servants of light, the children of fire. The brightest flame casts the darkest shadows."
"The worthy gentleman [Mr. Coombe], who has been snatched from us at the moment of the election, and in the middle of the contest, while his desires were as warm, and his hopes as eager as ours, has feelingly told us, what shadows we are, and what shadows we pursue."
"Shadows are friends to men in black."
