This is the quote at the beginning of The Field. It really sums up the theme of the entire novel.
“What we call empty space contains an immense background of energy. This vast sea of energy may play a key part in the understanding of the cosmos as a whole. Space, which has so much energy, is full rather than empty. What we perceive through the senses as empty space is actually the plenum, which is the ground for the existence of everything, including ourselves.” ~ David Bohm, physicist
