Thus far I have referred only to the necessity and benefit of this principle being practised in a moral point of view. I have said nothing about the physiological side of the question. This is one of if not the strongest sources of argument in its favor; but I do not propose to enter into that branch of the subject to any great extent on the present occasion. We are all, both men and women, physiologists enough to know that the procreative powers of man endure much longer than those of woman. Granting, as some assert, that an equal number of the sexes exist, what would this lead to? Man must practise that which is vile and low or submit to a system of repression; because if he be married to a woman who is physically incapable, he must either do himself violence or what is far worse, he must have recourse to the dreadful and damning practice of having illegal connection with women, or become altogether like the beasts. Do you not see that if these things were introduced among our society they would be pregnant with the worst results? The greatest conceivable evils would result therefrom! How dreadful are the consequences of this system of which I am now speaking, as witnessed at the present time throughout all the nations of Christendom! You may see them on every hand. Yet the attempt is being continually made to bring us to the same standard, and to compel us to share the same evils. When the principle of plurality of wives was revealed I was but a boy. When reflecting on the subject of the sealing power which was then being taught, the case of Jacob, who had four wives, occurred to me, and I immediately concluded that the time would come when light connected with this practice would be revealed to us as a people. I was therefore prepared for the principle when it was revealed, and I know it is true on the principle that I know that baptism, the laying on of hands, the gathering, and everything connected with the gospel is true. If there were no books in existence, if the revelation itself were blotted out, and there was nothing written in its favor, extant among men, still I could bear testimony for myself that I know this is a principle which, if practised in purity and virtue, as it should be, will result in the exaltation and benefit of the human family; and that it will exalt woman until she is redeemed from the effects of the Fall, and from that curse pronounced upon her in the beginning. I believe the correct practice of this principle will redeem woman from the effects of that curse--namely, "Thy desire shall be to thy husband, and he shall rule over thee." All the evils connected with jealousy have their origin in this. It is natural for woman to cleave to man; it was pronounced upon her in the beginning, seemingly as a punishment. I believe the time will come when, by the practise of the virtuous principles which God has revealed, woman will be emancipated from that punishment and that feeling.
