There&#x27;s nothing in your statement &quot;it is against human nature&quot; that would imply that it was just an expression of your opinion. You stated it as clearly as possible, yet you have no basis for this. It&#x27;s very sad to see the standards drop so low when the discussion regards human behaviour; it borders on religious faith. People believe X regarding human behaviour in the same way other people believe in <i>baby jesus</i>.<p>&gt; the challenge to find a counter-example to my argument is called proof by contradiction.<p>I don&#x27;t think &quot;proof by contradiction&quot; means what you are &quot;expecting&quot;, really. Look it up. You&#x27;ll see why and how fallible it would be as a method for human and social sciences.
