These are actual quotes from Brigham Youngs speeches.
Speaking about reincarnation, he said:
"It has been, and is now, believed by numerous individuals, that the brute creation, by increase in knowledge and wisdom, change their physical or bodily organization, through numerous states of existence, so that the minutest insect, in the lapse of time, can take to itself the human form, and vice versa. This is one of the most inconsistent ideas that could be possibly entertained in the mind of man; it is called the
transmigration
of souls." - Journal of Discourses 1:92
Speaking of the spirit leaving the body at death, he said:
"Here, then, you see it passes from a mortal tenement, from the carcass, or flesh and bones, something similar, perhaps, to the butterfly being born from its coarser tenement;not that I wished to advocate anything like
transmigration
; but as the butterfly sallies out of the cocoon, leaving it to be manufactured into fabrics, and free-and-easy she moves in another element, basking among the flowers of earth, so the spirit emerges from the body, to regale itself in a more congenial clime." - Journal of Discourses 8:26
Personally, I think its quite hypocritical for Brigham to condemn people for believing in transmigration of souls reincarnation, or past lives when the Mormon concept of "eternal progression" of the spirit into a god is no more strange.
Regarding Blacks, he said:
"The first man that committed the odious crime of killing one of his brethren will be cursed the longest of any one of the children of Adam. Cain slew his brother. Cain might have been killed, and that would have put a termination to that line of human beings. This was not to be, and the Lord put a mark upon him, which is the
flat
nose
and black skin. Trace mankind down to after the flood, and then another curse is pronounced upon the same racethat they should be the "servant of servants;" and they will be, until that curse is removed; and the Abolitionists cannot help it, nor in the least alter that decree. How long is that race to endure the dreadful curse that is upon them? That curse will remain upon them, and they never can hold the Priesthood or share in it until all the other descendants of Adam have received the promises and enjoyed the blessings of the Priesthood and the keys thereof. Until the last ones of the residue of Adam's children are brought up to that favourable position, the children of Cain cannot receive the first ordinances of the Priesthood. They were the first that were cursed, and they will be the last from whom the curse will be removed. When the residue of the family of Adam come up and receive their blessings, then the curse will be removed from the seed of Cain, and they will receive blessings in like proportion." - Journal of Discourses 7:290
