Some quick, handy references

I just read that an Australian Senator called Fierravanti-Wells said the following:

I believe that marriage is between a man and a woman ... coming together in one unique union. That is what it has been for every culture, in every ethnicity, in every faith in every corner of the world for thousands and thousands of years.

Suggested reading:

• Wikipedia entry on polygamy
• Wikipedia entry on polyandry
• Wikipedia entry on the history of same-sex unions

The primary literature is cited in those entries. Also:

• Skeptic's Annotated Bible entry on what the Bible says about polygamy

It would appear that the premise of this particular argument is demonstrably false. It would further appear that it is also not a logically valid argument, regardless of the truth or falseness of its premise:

• Logical Fallacies > Fallacies of Relevance > Irrelevant Appeals > Appeal to Antiquity / Tradition
