Edgar Rice Burroughs,
The Master Mind of Mars — Chapter V: THE COMPACT
(1928)
“ I have passed the allotted natural span of life, but I am not through with my life's work--I have but barely started it. I must not die. Barsoom must not be robbed of this wondrous brain and skill of mine. I have long had in mind a plan to thwart death, but it required another with skill equal to mine--two such might live for ever. I have selected you to be that other, for reasons that I already have explained--they are undefiled by sentimentalism. I did not choose you because I love you, or because I feel friendship for you, or because I think that you love me, or feel friendship towards me. ”
