What metaphors are used in In Dubious Battle by John Steinbeck?

Metaphor:

"A man in a group isn't himself at all; he's a cell in an organism that isn't like him any more than the cells in your body are like you.”

“You might be an effect as well as a cause, Mac. You might be an expression of group-man, a cell endowed with a special function, like an eye cell, drawing your force from group-man, and at the same time directing him, like an eye. Your eye both takes orders from and gives orders to your brain.”
