Alan Keyes: "No, you don't understand the difference between incident and essence. Homosexuals are essentially incapable of procreation. They cannot mate. They are not made to do so. Therefore the idea of marriage for two such individuals is an absurdity."
I'm glad Keyes brought up the difference in substance/nature. He's exactly right, and it's clear that this guy Signorile is not familiar with the terms and philosophical background of those terms that Keyes is using. Aristotle, Aquinas, etc., distinguished between ESSENCE and ACCIDENCE (or, as Keyes refers to it "incidence").
Even if scientific/medical advances someday make it possible for homosexual males to procreate, it is not an "ESSENTIAL PREDICATION" of their NATURE--the natural capacity is not present on their souls.
Likewise, even if Liddy Dole is not now able to procreate, it is still in her nature to do so AS A WOMAN (that is, as women are designed-the natural capacity).
Which is to say, women AS SUCH are designed by NATURE to procreate. Men are not. This is, it is part of the design inherent in their soul. Even if that CAPACITY is not realized, or able to be realized, the CAPACITY is part of the original design of the soul of women.
The fact that Liddy cannot is an ABBERATION or LACK of something that is part of her natural, original design.
I'm shooting from the hip here in my definition. If I took more time I could clean it up. Hope my definition is not misleading or too poorly worded. This gets complex.
I refer people who would like a more thoughful, exact background in this to read a book titled Philosophical Foundations For A Christian Worldview by J.P. Moreland, and William Lane Craig. Specifically, read those chapters on metaphysics.
That might lay it out better than I'm doing right here.
There are lots of other books, but that's just one that comes to mind. Also, a book titled BODY AND SOUL by J.P. Moreland goes even more into detail on this subject, but it's a difficult read for many.
Please feel free to make any corrections, or to elaborate on my post #168 :o)
