"For, after all, how do we know that two and two make four? Or that the force of gravity works? Or that the past is unchangeable? If both the past and the external world exist only in the mind, and if the mind itself is controllable – what then?"
"Reality exists in the human mind, and nowhere else."
"Always eyes watching you and the voice enveloping you. Asleep or awake, indoors or out of doors, in the bath or bed- no escape. Nothing was your own except the few cubic centimeters in your skull."
"He was a lonely ghost uttering a truth that nobody would ever hear."
