Arthur Schopenhauer,
The World as Will and Representation…
“ Let any one try to present vividly to his mind the time, in any case not far distant, when he will be dead. Then he thinks himself away and lets the world go on existing; but soon, to his own astonishment, he will discover that he was nevertheless still there. For he intended to present the world to his mind without himself; but the ego is the immediate element in consciousness, through which alone the world is brought about, and for which alone it exists. This centre of all existence, this kernel of all reality, is to be abolished, and yet the world is to go on existing ”
