"All matter originates and exists only by virtue of a force which brings the particle of an atom to vibration."
"The inability to perceive that existence preceded creation is the primary barrier to understanding."
"Anybody who has been seriously engaged in scientific work of any kind realizes that over the entrance to the gates of the temple of science are written the words: 'You must have faith.'"
