Let this expression signify the belief that the soul is something indestructible, eternal, indivisible, that it is a monad, an atomon: this belief must be thrown out of science! Between you and me, there is absolutely no need to give up “the soul” itself, and relinquish one of the oldest and most venerable hypotheses – as often happens with naturalists: given their clumsiness, they barely need to touch “the soul” to lose it. But the path lies open for new versions and sophistications of the soul hypothesis – and concepts like the “mortal soul” and the “soul as subject-multiplicity” and the “soul as a society constructed out of drives and affects” want henceforth to have civil rights in the realm of science. By putting an end to the superstition that until now has grown around the idea of the soul with an almost tropical luxuriance, the new psychologist clearly thrusts himself into a new wasteland and a new suspicion.
