Nevertheless, the return of material beings with regard to species is evident; so the trees which during former years brought forth leaves, blossoms and fruits in the coming years will bring forth exactly the same leaves, blossoms and fruits. This is called the repetition of species. If anyone makes an objection saying that the leaf, the blossom and the fruit have been decomposed, and have descended from the vegetable world to the mineral world, and again have come back from the mineral world to the vegetable world, and, therefore, there has been a repetition-- the answer is that the blossom, the leaf and the fruit of last year were decomposed, and these combined elements were disintegrated and were dispersed in space, and that the particles of the leaf and fruit of last year, after decomposition, have not again become combined, and have not returned. On the contrary, by the composition of new elements, the species has returned. It is the same with the human body, which after decomposition becomes disintegrated, and the elements which composed it are dispersed. If, in like manner, this body should again return from the mineral or vegetable world, it would not have exactly the same composition of elements as the former man. Those elements have been decomposed and dispersed; they are dissipated in this vast space. Afterward, other particles of elements have been combined, and a second body has been formed; it may be that one of the particles of the former individual has entered into the composition of the succeeding individual, but these particles have not been conserved and kept, exactly and completely, without addition or diminution, so that they may be combined again, and from that composition and mingling another individual may come into existence. So it cannot be proved that this body with all its particles has returned; that the former man has become the latter; and that, consequently, there has been repetition; that the spirit also, like the body, has returned; and that after death its essence has come back to this world (284:1)
