I received your book--"The Tyranny of God"--and have read it through. I think as you do that death ends all, yet I do not feel certain, because there are many facts that seem to show that the real units of life are not the animal mechanism itself, but groups of millions of small entities living in the visible cells. The animal being their mechanism for navigating the environment, and when the mechanism fails to function, i.e. die, the groups go out into space to go thru another cycle. The entities are each highly organized and perform their allotted task. If there is anything like this we still have a fighting chance. You have doubtless read interviews I have given lately on this subject. They appeared in the Scientific Monthly for October 30, 1920 and the Cosmopolitan for May, 1920. Yours very truly, Thos A Edison Famous Inventor Gives Views of Death and Immortality in Correspondence with Author of "The Tyranny of God."
