Jonathan Safran Foer said this quote
“ A simple trick from the backyard astronomer: if you are having trouble seeing something, look slightly away from it. The most light-sensitive parts of our eyes (those we need to see dim objects) are on the edges of the region we normally use for focusing. Eating animals has an invisible quality. Thinking about dogs, and their relationship to the animals we eat, is one way of looking askance and making something invisible visible. ”
