knife, against the “atomistic requirements” which still lead a dangerous after-life in places where no one suspects them, like the more celebrated “metaphysical requirements”: one must also above all give the finishing stroke to that other and more portentous atomism which Christianity has taught best and longest, the SOUL-ATOMISM. Let it be permitted to designate by this expression the belief which regards the soul as something indestructible, eternal, indivisible, as a monad, as an atomon: this belief ought to be expelled from science! Between ourselves, it is not at all necessary to get rid of “the soul” thereby, and thus renounce one of the oldest and most venerated hypotheses — as happens frequently to the clumsiness of naturalists, who can hardly touch on the soul without immediately losing it.
