His weakened body quit functioning is all... You cannot kill Christopher Hitchens, Christopher Hitchens will live on in his work, in the words he has written, the thousands of hours of video of him, in the conscious minds of EVERYONE that has listened to his voice or read his words.... You can NEVER kill that, neither can it ever die....
Christopher Hitchens is not dead, he has just past from life into immortality. Not an immortal nonexistent realm of the eternal "soul".... but into the realm of the immortal literary geniuses.
Christopher Hitchens did not die... he just finished his final book. The ONLY book of life there is, once it is closed you do not return but what you leave behind lives on for you as a namesake. The namesake of Christopher Hitchens will never die.
To wipe Christopher Hitchens from the face of this planet you would need to find every copy of his books... That is a list of a few.. 50 or so that he wrote, co authored etc... just a few...... there are others I may have missed...
To kill Christopher Hitchens you would have to remove ALL his work... Can't be done... Christopher Hitchens did not die... he is now an immortal... not a god... not in hell nor a heaven... Christopher Hitchens lives on in his work and in the minds of millions that respected him, cared for him, loved him, believed in him... and yes even in those that hate him still... until his memories are removed from our minds, his work removed from our bookshelves, libraries and from all forms of written, recorded history... he shall live on...
