"Lamettrie goes back to the father of the Church, Arnobius, from whose book, ' Adversus Gentes,' he borrows a hypothesis, which possibly became the original of the statue-man which plays its part in Diderot, Buffon, and particularly in Condillac. Let us suppose that in a feebly illuminated subterranean chamber, from which all sounds and sense-impressions are far removed, a new-born child is scantily nourished by a naked and ever-silent nurse... reared up without any knowledge... of the world or of human life until the age of... forty years. Then let this being leave his solitude. And now let him be asked what thoughts he has had in his solitude, and how he has been nourished and brought up. He will make no answer; he will not even know that the sound addressed to him has any meaning. Where now is that immortal particle of deity? Where is the soul that enters the body so well taught and enlightened? Like Condillac's statue, then, this creature, which has only the shape and the physical organisation of a man, must be supposed to have received feelings through the use of the senses that gradually arrange themselves, and education must do what else is necessary to give him the soul, the capacity for which is only dormant in his physical organisation. Although Cabanis, as pupil of Condillac, rightly rejected this unnatural hypothesis, we must nevertheless concede to it a certain justification as compared with the extremely weak foundation of the Cartesian doctrine of innate ideas."
